Most overlooked brake maintenance procedure. Note: When pushing the pistons back in, make sure you're pushing them straight in. If you're pushing with an angle then the piston will get stuck. Hold the other pistons down and pull the brake lever so it comes unstuck. DON'T try and push it in with force if its stuck. It should go in smooth with little force.
Best brakes I ever had! Easy to install,bleed and maintain. Great design and absolutely crazy braking power. Soon I will replace everything on my bike with your stuff 😊 I'm very satisfied
I have the RX4+ callipers (shimano version) which use Shimano mineral oil. My understanding is that the silicone lubricant should not be used with mineral oil. I've just used the mineral oil to lube the pistons. I know most Hope brakes use DOT fluid, but might be worth clarifying this.
Hi ! many thanks indeed for your technicals tutorials. I wonder if you will make one for a full rebuilt for Hopetech 3 levers assembly and rebuit Best Regards
I’ll try the piston lube on the road 4-piston callipers. I’ve got mine perfectly centred having just fitted them but whatever I try the front brake always rubs after the brake has been applied (pistons don’t retract properly). It’s doing my head in having spent an hour trying to sort it out following the Hope guide step by step.
Nice video very helpful.. Keep up.!! If disc cleaner damage seals why not to try to make better compound seals.. I would be happy not to worry about damaging them when cleaning my bike
Why you would just not be idiot 🙃 if you put brake cleaner on pistons when you will get them back in place they will go on seal and seals are in contact with the dot inside the circuit and degreaser+dot isn’t really good 😅😂
Great video - really helpful. I’ve been through all the procedures for my rear brake, but have now lost all pressure in the brake system. I did the work with bike upside down, not on a stand- could this have caused loss of pressure perhaps? Do I now need to bleed the brakes?
Hey from Aussie … Love all my Hope parts man, wondering if it should be or needs to be done or would it gain me anything to wind both levers all in/out #BPC & Reach or leave as I’ve had them set up previous to lubing etc.. Running V4 Tech 3 setup Cheers
Can’t find hunter silicone lube in the US, is there some thing else that comes recommended? I can find silicone lube in a spray can, can I just spray some in a cup and apply with a brush?
Thanks for making this video, I've watched the one you guys posted years ago a bunch of times. I have the V4 calipers with regular rotors (not vented) so the pistons have to be pushed out more than normal to bite. I noticed that the pistons don't all push out at the same time (one or 2 always seem to stuck or slower. I am pretty sure I need to lube them but I can't find the lubricant anywhere. What lubricant do you recommend that I use to lube the pistons?
Mark Davey thank you very much, I am in US so I didn't find that product but once I searched for silicone grease I was able to find a similar product. Thank you!
i would like to see a wheel spin after pads was fitted.. i am sure it was sound like hhhhzzzz hzzzzz hhhhhzzzzz hhhzzzz there is not even a mm space there with pads on
@@justinholmes5614 pads are constantly in contact with the rotor no matter what. No audible rub thank god but with the bike in a stand the wheels don't spin freely.
nathan fagan Mine were like that until I greased the pistons and worked them in and out over and over. I took the wheel off and wedged a plastic screwdriver between 2 of the pistons to hold them back, then pumped the break until the other 2 came out a long way. Dab of silicone grease all the way round with a cotton wool bud and pushed them back. Do the same with the other 2 pistons. Once they are greased take the time to keep pumping the pistons out and push them back until they all move the same when you pump the brake.
Najgorsze hamulce z jakimi miałem doczynienia. Archaiczna konstrukcja z jakąś chorą metodą odpowietrzania i ustawiania. W Shimano czy Sram odpowietrzanie to 3 minuty,a tu godzina i dalej są miękie. Nie rozumiem zachwytu nad tym gównem.

How often should I be doing this to my brakes?
Best brakes I ever had! Easy to install,bleed and maintain. Great design and absolutely crazy braking power. Soon I will replace everything on my bike with your stuff 😊 I'm very satisfied
I have the same brakes and wondering how often you do this procedure?
Thanks a lot for making these new ones. Much appreciated!

Great video very helpfull for maintaining my v4 brakes
Tip use colored parts in the instruction video its way easyier to see that way 👍🏼
Loving these new videos. 👍

Did you ever find the solution to this? I’ve just installed some new hope callipers and having the same problem, the pistons don’t retract.

I got a brand new, out of the package V4 Vented rotor from CRC that is lightly warped. Makes for a frustrating time lining up the caliper....
hello can use rubber grease to lubricate piston and seal
Hello, I would like to know which tool did you used to change the "caps" of the calipers... the green one, to understand.... thank you :)
Can you get a direct mount for the V4 brakes ?
Can’t find hunter silicone lube in the US, is there some thing else that comes recommended? I can find silicone lube in a spray can, can I just spray some in a cup and apply with a brush?
Could you help me, i just replace my hope tech3 V4 with jagwire pro mountain hose and jagwire hyflow quick fit, but the brake dosnt working as well.
Dose anyone know if hope floating rotors will fit on a 2018 specialised enduro elite 27.5 with Öhlins fork
D_blade face of hope tech this is an awesome move away from that drone Nick Owen
Lube attracts dirt and dust. Just clean the pistons with isopropyl alcohol.

steven yeah but the funny thing is when I look for silicone lube online all I see are sex lubes. I'm pretty sure that's good for my pistons
Mark Davey thank you very much, I am in US so I didn't find that product but once I searched for silicone grease I was able to find a similar product. Thank you!
@@TommyHuynh Maybe sex lubes would work pretty good, who knows :-)
Hope recommend Hunters Silicon Lube
Hi is there any reason why I can’t add v4 pads to e4s? Thanks
If not then may I ask why hope don’t manufacture ebike pads for e4s?
are the pistons not soaked in brake fluid inside the calipers, why do you need to lubricate or clean them :D
They aren’t in this case.
what's the lube you put by the brush on pistons?
Kirill Romchanov it’s a silicon grease.
Hope Silicon Grease 30ml www.amazon.co.uk/dp/B0062N50S6/ref=cm_sw_r_cp_tai_MWz1DbXK6N2VW
The Hope spanner you use is that available and what is the name/part number?
I would also like to know this
google hope closed system cap spanner
i would like to see a wheel spin after pads was fitted.. i am sure it was sound like hhhhzzzz hzzzzz hhhhhzzzzz hhhzzzz
there is not even a mm space there with pads on
No matter what I do, they won’t centre. Seriously regret buying these :/
Edit : They are doing much better now I’ve stopped being such an angry prat.
Same on my current bike. Beautifully machined, yes. Easy to look after, debatable.

Mine are working well now after A LOT of fiddling. What are you having problems with ?

Don’t forget to wind the bite point screw right out before you start.
You don't have to be Northern to work 'ere, lad, but it bluddy well 'elps!
Is lithium grease okay to use in place of silicone grease?
I just cannot push the pistons back, since the brake brand new, even two of the pistons cracked so easily, very disappointing
That rotor is bent. Good video though.
hi what is tha tool you use to push the pistons back?
These work for mepedros.com/products/tools/wheel-and-tire/tire-levers/
Use a flat screwdriver it’s way easier
Wera key's are desent
