This week I restore all four of the brakes from the E30 to a factory gold zinc plated finish. This one got delayed due to post getting lost. Slowing getting sorted in Spain but still in the process.

PROCESS:
Firstly I remove any brake pipes from the calipers. I then dismantled them completely. I then wash all of the pieces in the parts washer before plugging them with moldable plastic to protect against the blasting media in certain areas.
I then blast all of the parts excluding the pistons. Once all of the grease, oil, dirt, and rust has been removed, It's time to zinc plate the main pieces. It took me three days to plate and passivate all of the parts including dry time.
Whilst I was waiting for them to dry, I blasted the clips for the rear brakes and painted them in heat-proof black and clear coat. It was then time to put everything back together. I used a cool trick of putting the seal on the piston before installing it. This made life so much easier. The pistons should go in without any mechanical force.
WIth the pistons back in I added the sliders and pads before finishing them off with new rubbers and bleed valve covers. The restoration was complete.

Ok, Ok I will help you out for those that are stuck and can't get the pads back in (E36 etc). So no matter which way you try like the guy in the video there isn't enough space right? Remove the sliding pins, put the pads in and then put the sliding bracket over the pads (copper grease etc.), finish it off with screwing the pins back in. Also you will notice fitting the sliding pins from this side allows you to load them up with much more silicone grease.....you're welcome!
it's how you would have done it if they were mounted on the car by not removing the entire caliper, leaving the bracket on.
wasted so much time trying to do it like this guy shouldve checked the comments first
This is just my opinion. A great part of enjoying restoration videos is seeing how it looks at the end. You show the end product in the thumbnail, taking away the “surprise” - the “wow” factor.
This is so satisfying!! Specially the zinc coating. Good job!
Electroplating only works when there is clear line-of-sight between the anode and cathode. If the inside of the caliper did not directly face a plate the zinc will not transfer.
Your plating solution also needs movement... this video might help you...th-cam.com/video/Nmn94B5UUuU/w-d-xo.html
In addition to PHATJANUS and rustmans comments you need good current density throughout the part. The current will take the path of least resistance, in a larger part like the front calipers you didn't get much current through the underside there. So more current and/or you can also try moving your contacts around for a better result.
AND If you're going to be plating parts at home BAKE THEM after. With zinc nickel plating and acid pickling you are at risk of introducing hydrogen into the microstructure of the steel and making it brittle. It's really only of concern for hardened parts but as a safe bet it won't hurt to just bake everything. Look up hydrogen embrittlememt for some recommended times and temps, but you want to bake those parts within an hour of plating/passivating for a couple hours at 180C or so.
Keep up the good work!
@@patricklandusky7467 You seem to know your stuff. In the video he plates the sliding pins and the inside of the bits that the pistons sit in, would that interfere with their operation as you're adding a layer of zinc to something that should already be a very tight fit?
@@KineticLatency The pistons should be sliding on the seals, which will be a smaller diameter than the inside of the cylinder, so a thin layer of zinc shouldn't affect it.
@@KineticLatency thats why he left the seal in place till the finish.
When I was a much younger fella, I worked in an electroplating shop.
Firstly, we used metal hanging brackets as they gave greater conductivity and surface area contact, but!..... Secondly, when we had odd shaped items we knew would not plate well, we always added an additional contact wire as close to the affected area, this extra wire would help spread the current more evenly and efficiently hence increasing said area of electrical excitement and attracting more of the energised particles.
Seemed to garner better results for us, I'm going back 40 years so technology may have improved since then.
They have custom racks now with selectable paths. So you coat section A then disable that one's path, and start path B and so on. Visited a plating business for antique restoration recently.
It must be so much nicer doing this work in the new shop/workspace.
It's amazing thank you Aaron. A lot more walking but I'm getting used to it. The shop is only 20% finished, so I have a lot of work ahead of me.
@@RestoreIt Only 20 percent?? Wow I can't wait to see what else you have planned!
Agreed
You should paint it red
It will give you extra 20 whp
dont you mean bhp??😂😂
And +25 bhp for yellow one
@@Niggabalzz wheel horsepower is more relevant than brake horsepowers, you can lose a lot of power between the engine and wheels.
@@CA-gy4qf i said BRAKE hp because he is restoring the BRAKES😂 come on man it was just a joke
@@Niggabalzz that one went way over my head I'll admit 😂
It’s always nice during a busy day to pump the brakes (so to speak), kick back and watch another awesome video of yours! Thanks for posting!!
lovely
back to brand new status
great detailed handiwork, patience, craftsmanship
thanks for taking the time to put this together
You should get some big rubber sheet and put it on the tables. It will look nice, you wont damage the wood and most importantly its super easy to clean. Also put some at least 5mm plate under your vice to eliminate the flex when you were removing the brake lines at 4:40. Keep up the good work, your videos are my inspiration
Thank you Jondra! You read my mind. All of this to come in the workshop videos!
Buy you a set of flare wrenches also, it will help you not strip out your hose connectors.
@@RestoreIt Could also consider a sheet of acrylic for the disassembly bench, even easier to clean, and easily replaced. Also extremely cheap.
That terrazzo floor is the best, durable, smooth, easy to clean, looks great. There's nothing like it for an immaculate workshop. What a great base for your new working environment!
Thank you Wilmer! A lot of people have suggested i cover it, but i also quite like it.
Yes, but spraying paint around...no sheeting or spray booth, (cardboard box will do.. hmmm
Nice work! I love how the calipers came out looking. Well done and keep up the good work on this restoration journey. Be proud!
You do such excellent work ! I have been watching since you started this project and have enjoyed every video . Looking forward to seeing the finished project .
This channel is so addictive. Nice work. Cannot wait to see this car completed!
You don't need so much copper anti-seize on the back of the brake pads. A light coat near the contact point is fine. Now the copper anti-seize is just going to collect brake dust and look nasty bro
And now the sky will fall because of it.
@noxxi knox Yes, that sky is so full of that nasty C02
@noxxi knox i get at least 4 cars in a day with rubber backed pads for break squeal. throw some antiseize on the back of the pads and it works every time.
@noxxi knox True that, cant be having the people smelling cow farts.
@noxxi knox They're all cars with electronic e-brakes. Ebrake digs into the rubber and gets stuck onto the picton.
The metal plating is gorgeous. Very good work.
Another method is to leave the pistons and seals in place, then remove the brake lines and seal the opening with another brake bleed screw (usually it’ll be the same thread as the brake line). The bleed screws are cheap and you can plug the end with silicone or something. This lets you sandblast every surface that will be exposed to the elements, then you remove the old stuff and clean the inside of the caliper by hand
Nice one Steve!
Im always watching your videoes..
Please hurry up we need more videos in week:(
Dude thank you.
This video is two weeks late. I am so frustrated, it's unreal. I have another video completely ready because of a postal issue.
Expect a lot more content soon. More than one video a week. I'm still getting on my feet in Spain, it's a right pain in the ass. But soon I'll be there and the content will flow.
@@RestoreIt Come to Germany when ur car is ready
@@RestoreIt How are things going for you in Spain? I'd really like a video where you just talk about the reasons for moving, how you chose where you are, pros and cons etc
@@RestoreIt Power plug should be protected more from liquid.
Keep on keepin on. Your inspireing me to do this with my car
Brilliant restoration as always.
Wow. Just love your videos. I know nothing about cars but I can watch you all day!
Wow, they look beautiful. Great work. I rebuilt mine a couple years ago. I didn't have access to a blaster for the rust, so just soaked the calipers in a couple gallons of vinegar. That actually worked really well. I need to learn more about your zinc plating process..... that looks highly interesting.
I liked the idea of outing the pressure blaster hose in the bead cabinet, I'll have to try that.
Zinc plating gives incredible results!
They look amazing! Awesome!
Can't wait for the next shop update video! I love your videos!
I am really excited to see the fully restored E30
During the zinc plating I noticed a little taste of nostalgia in the background...the label container drawer organizer. Yep that was always there in the old shop in view. Glad it's still around. Relief.
Hello you are not shy when it comes to hard work l swear you did everything the hard way but l was entertaining thank you so much for sharing
Awesome as usual! Can’t wait to see the car rolling. 👍🏻
Thanks ZMO999! It wont be long!
Great video, excellent work. The finished product looks awesome. Keep up the good videos 😀.
Sweet finished product!
Beatiful job.
Interesting your work great detains. Thanks you very much for all steps. I have seen 3 o 4 times that video and I tell you I am not tired. I live in Nashua NH and I am becoming to be your fan.
Awesome job n very interesting viewing. Thanks n keep up the good work...
Watching this makes me think I should finish off refurbing the wheels I've had in my garage for the last 6 months ;) Nice job, as always man :)
Thanks man...always enjoy your work...amazing
Time to christen the new workshop with an E30 restoration video!
Oh hell yes! So many more to come :)
Restore It can’t wait to see them!
Cant imagine a lot of used brake calipers that gets to go through this deluxe spa treatment. Looking pro with that putty to mask surfaces from the blasting. +1
really addicted to your videos man , keep going
Hi, Steve! Your new shop is awesome! Your brakes turned out really nice. I like how you have a system to plate/coat them. Your car is going to be a show piece. I'm saving up now so I can get over there for a ride once it's finished. Hahaha! See you soon in the next video. Take care, my friend.
Wow that playing came out great!
Very nice work. Excellent results.
Phenomenal restoration
Looking good! Back to spec with a little bit of elbow grease!
YOU ARE SIMPLY A BRILLIANT PERSON.... 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Great job!
I can't wait to see your brand new BMW
You are very brave having your fingers so close to the piston when popping it out lol, usually i will lay a folded up towel on top of the caliper just in case things go wrong.
That's a great result.
Very Nice Job Bro Those Came Out Factory New
Great job, what a transformation. They're better than new and will look fantastic on the car. How much longer do you think it will be till you start to actually rebuild the car. I think it will be priceless when it's done due to the immaculate detail you go to on all the restoration. Can't wait to see it.
As always excellent content, keep up the good word dude!!
Great work ! 👍🏻
im not sure, but did you make your workbenches from MDF? if so you should put a different sheet if wood on top. oil and water will desolve the binding glues and MDF will swell and fall apart. then you get all these holes in your table, and weird MDF fibers on all the stuff your working on.
Great work
Beautiful result! Great job :)
well done young man!
Excellent job
Amazing! I love your work and you inspire me to restore my truck!... greetings from Argentina!
Thanks Yaikerz! Good to hear!
i get so excited when there's a new upload.
Děkuji za video, vysoce kvalitní obraz fotoaparátu. Good job!
Slick result!
Peace of art ! Wow
Thanks man!
This is gonna be the cleanest E30 on the planet when it's finished.
Nice job man. They came out good. I hate breaks at the best of times, you made it look easy :) nice!
Thanks dude. It certainly was not easy haha.
in this video he deals qith calipers that have recently been in use ....as the pistons popped out with just a bit of air pressure... being a mechanic i have come across hundreds of seized pistons in calipers that will not "pop" out with air no matter how much pressure is applied, the solution i found was to use a grease gun, simply take off the nipple tip and screw the thread into the hose thread on the caliper ...you can now apply 3000 psi of hydraulic pressure at a very controlled rate.... the piston "WILL COME OUT". every time, then its just a matter of cleaning the grease out of the caliper, this whole process takes 5 mins if you have the tools at hand, if you dont have a grease gun, go and buy a cheap pump action one. its so worth it
16.11 the main project of restoration have sneak peek.... very good job my friend.
Nice work 👍🏻👍🏻👍🏻
I’m going to have to watch all the BMW videos again to get a feel for how many parts we have done and how many are left to be done.
Good job , respect 👍💪
So damn satisfying
This is a fantastic series of restoration videos, I’m loving them!
i love your work
BMW Company Proud of you
Nice job!
It's so nice watching these videos knowing that if I want to learn a better way to do it all I have to do is read the comments from all of the couch blistered experts.
Neat work. Good job.
Brilliant, absolutely fine ... my Led Zeppelin of restoring videos ...
Beautiful job as always. I always put a high temp clear over zinc plated calipers. Just about all wheel cleaners are acidic and will burn the zinc right off.
12:44 was that a fish tank heater? Love the series! You are doing an amazing job with an amazing piece of history!
Well done. Cheers
nice work
Fantastic job i liked
Very good restoration bro 👍👍👍👏👏👏👏
Thanks man!
Loved seeing the plating. Worried about reusing pitted pistons even after refinishing.
I love watching your videos they are so satisfying! I do have one question though, you must not have any kids to have the time to do this. I can't even take a dump without getting bothered! Haha keep up the good work man I love it! 👍👍👍👍
New workshop love and them calipers are shot
Good job bro 😍😍
Your new shop is very nice.
Thank you, Gilbert. It's only around 20% finished. I have so much to do. As well as keeping the restoration videos coming. I'll get there :)
Sick resto! Thank you for sharing.
You definitely don’t do things by half measures. All power to you!
Nice job
Nice refurbish and rebuild. I realize you could have simply bought new or rebuilt ones, but now you know that are truly good and no worries if rebuilt ones will actually work. Not all the rebuilt parts you purchase in any auto parts store are good and quality reworked. I know that first hand... Thumbs Up!

They had excellent condition.
When I get notification of a new video by you I stop whatever I'm doing and watch immediately. Love it!
very good job !
You should try running a dust collection/air filter system on the blast cabinet. They make a world of difference. They suck out the dust on one end while sucking in clean air on the other. When the system fills you just dump it back into the blast cabinet.
New bench, nice.
