- Trimming down your brake hoses is something you need to do when installing fresh brakes, or perhaps to tidy up the cockpit on a new bike. Long unsightly cables can catch on stuff and rattle when you are riding. As with any mechanical job, it’s fairly straight forward as long as you follow a process. Here’s how🔧

How???? I order new hoses 25 minutes ago and now this has been up for 15 minutes, i think doddys a psychic
Cheers Doddy. But you are 2 weeks late for me, had to cut and swap both hoses on new brakes. One tip not mentioned for Shimano - a drop of mineral oil on the olive to help it seat and seal nicely 👍🏻
Excellent timing, just as I was in process of getting things together to sort out a brake upgrade. Thanks for that.
same here.
Great timing! I just shortened my brake hoses yesterday!!!
Love these videos. I’ve learned so much from y’all.
The hose clamp system has worked fine for me every time.
Very useful video. Thanks!
Great video once again thank you for all the wonderful entertainment! Wish you all the best from me and my Channel!❤️
Good video, haven’t needed to do this yet but at least I know how for when I do need to do it.
Good video Doddy! Thanks
genius as always thanks mate!
that bike is so clean!
I just got a message that my new dominions were ready to be picked up 2hrs ago. Perfect timing!
well good for u, btw they suck big ass.............good luck on the long term with those boi
Very nice Doddy. 👍
Thanks for the help! You saved me a lot of money instead of going to the bike shop!
Thank you for this Video! :)
Brilliant!
I did this a week ago so vids too late 😂 basically just made it up as I went had no professional toolsbut it worked out good. Did a shagura so shimano lever Migura caliper cos I hated the magura lever. It works so I’m pretty chuffed.
Hellow, Second video that I see, the first was the insurance to take care of the bicycle, greetings from Mexico, good morning England.
Great vid...clear, good length...and a job needed every time u get a new bike or brakes.....
That's a nice bike 😎
According to Shimano instructions you should put some premium grease on the olive before installing it
u dont need that ... plus u risk the fact u clog the hose with "premium grease" ........... greetings from The Netherlands!
Yo doddy, don t make people to scared. The cut doesn t have to be so accurate at a 90 degree angle. A propper cable cutrer will do the job if it is sharp. A sharp stanley knive will do too. That fancy park tool press is nice, but there are cheaper presses that work, like m-wave. Hittimg with a hammer is no option, as you will break the shimano insert. Get a presss for shimano, magura, tektro, all brands that do not screw in. Tighten the nut realy thight, close to the feeling of stripping out. ( be carfulll, but it has to be thight to avoid leaks). Then comes the real mecanic art, get the right kit for bleading. No aftermarket stuff... Shim for shim, sram for sram/avid, mag for mag, and shim also works for tektro. When you have all those parts go to youtube and fimd the right video for bleeding.your brand of brakes... Shim/tektro is easy, magura and sram/avid a pain in the bottom end. Hope is an other story with dot fluid, and hayes still a doubt for me. DO NOT reuse olives etc. New parts or nothing, and propper fluid of the brand of your brakes. Dot oil in mineral brakes will ruin your seals, olive oil in dot brakes will not slow you down when you are about to crash on a down hill.....
But then they dont get to justify their content to their sponsors
the music on this one was top xD
Slide the rubber cover well down the hose toward caliper, so u dont leave it on the cut off bit and forget it
My new bike came with a mile of cables up front. I do not have the proper tools. I think it may be best to go to the bike shop and let them do it. I also want to do the shrink wrap trick too.
Doddy, at the end when doing the last check with the funnel,do you activate the lever or just naturally let the air come out by it self??? thanks!!
You can use spare tyre valve retaining/securing 'nuts' to secure caliper bolts on caliper so you dont loose them or the washers
@seth
@Rupert Wenn Great tip!
Nicee
#askGMBNTech I need to replace my headset but now that I have checked the measurements(40mm cup) I cannot find a replacement. What can I do to fix this or do I have to just grin and bear it?? Thanks guys
I can do it without bleeding after?
One of the few jobs prefer to pay for
It doesn't have to be a perfect 90, and could probably even tolerate a 45 degree cut because it's not at the end of the hose where the seal is being made; the seal is happening between the compression sleeve ferrule (olive) and the insert. In other words, the hose is being squished between the ferrule (olive) and the insert when you screw it in and that deforms the ferrule, so that's why you can't remove and reuse it. I'm not recommending you cut the hose at 45, but it's not nearly as critical as the video makes it out to be.
Other than that, informative video!
Expensive people. Expensive work
Couple mins too late. I just fitted an xtr lever and shortned the hose to my bmx 5 mins ago
Great video. But what did you do at “cheeky little bleed”?
It
Remove a small amounts of air at the lever. It’s “cheeky “ because it’s not a full bleed which you’d need if there was too much air - or air stuck at the caliper. That would significantly degrade performance.
thanks for the reply. What i missed is HOW to do the cheeky little bleed at the lever.
@@billszymanski4844 flick the lever with the reservoir attached
Can we reuse the mineral oil after bleeding for removing air bubbles?
yes, If it is clean.
#askgmbntech hello there, I've got a little bit of a head scratcher for you. I have a 2019 Specialized Fuse Comp 27.5+ and I've scratched and pitted the heck out of my stanchions. It's a SR Suntour XCM32 fork. So the issue has been finding a replacement. I can't find a replacement upper, and as it's a straight steerer plus bike, I have been unable to find a different fork to replace it. Is there any way to refurbish the current uppers? Or perhaps a method to get a tapered to fit a straight steerer? I'd like to not have the bike be a loss if possible. It's not the main bike, but it's been ridden hard enough. Any thoughts?
th-cam.com/video/xAV7J93J9Z0/w-d-xo.html
(Link to a gmbn video about repairing stancion scratches)
next, how to lengthen the brake hose I just shortened ; ),
I have recently shortened my rear brake hose and now the pistons won’t work does this mean I need to do a break bleed
Yes
You forgot to run the hose through the fork first (at least on my bike) and leave a little extra hose in case of future change of bike or problems, tsk tsk😜
what is the name of that thing in the end of the hose
Barb or insert
You can get that barb in flat and 90 degree angle with your thumb. You just didnt try hard enough. Its not a lot of pressure.
This may be a dumb question... I want a more powerful front brake (being a fat lad with basic single piston Shimano) but they're very hard to find at the moment. If I order a rear brake from a German website (so lever on the right) will this be ok to put on the front with a shortened cable? I'm pretty sure it will but I often make stupid mistakes 😂 #askgmbntech
The calipers are identical front or rear, so the only difference is the lever side. It will work!
Maybe if you can, a larger rotor will give your single piston brakes more sauce.
Can you empty the remaining fluid in the funnel back to the bottle when done to reuse or is that waste when done?
if it looks clean then you can.
You have to tighten the olives in far more than you think, as the olive needs to be compressed....far tighter than shown in vid in order to compress olive properly, but not overtighten ...so you alsolutely need a proper torque wrench and crows foot 8mm....SRAM bleed kits come with the 8mm crows foot (use it at 90 degrees to your wrench)
How can you tell how much torque he was applying?
@@mattgies experience of the number of revolutions from when the fitting was 'nipped' up...would take a few more part turns on spanner...
The point is the olive needs crushing...which once firm (the point shown in the video), then requires further turning (which was not shown)
One area where the specified manf torque should be followed.
Though I have reused an already crushed olive before and not torqued, but then left overnight with the lever fully compressed/pulled and checked absolutely zero weaping/leak...an alternate method.
Correct torque also important to ensure it does not work loose over time and lead to a potentially catastrophic brake fail from fluid loss as ur bombing down some crazy trail!
Measure thrice, cut once
Personally, I would of added another 1-2 inches to the length Doddy chose. Because you know when you bleed you’d sometimes like to loosen and rotate the brake lever housing up plus I like there to be a bit more curve in the middle of the line.
Agreed, it'll also allow the owner to potentially upgrade there forks travel without paying out for another hose. Personally I'd say he's cut that at least 2" short maybe more
@@dicksplatts007 Yea I was being kind, but I would of made it closer to what a front brake hose would be like on a motocross bike where the 90 deg bend is further out, but not so much it bulges in the other direction towards the left when the fork is compressed.
This bike was really easy to assemble th-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike.

“Specific tool”, so a hammer then 😈
Works fine also never used a specific cutting tool when a Stanley or even a good set of sharp wire cutters do the job just fine. I'm sure he just likes to show off park tools bits
Did Canyon know that you show this on an orbea Bike?
Orbea is their new bike sponsor/channel partner.
One question: if don't shorten the hose, but replace it entirely, do i have to flood the new hose before closing the system? (First connect a syringe with fluid to the caliper, remove the old hose, connecti the new hose, then push fluid until it starts to come out on the lever end?)
A brake hose full of air will offer zero braking power! Take your bike to a professional would be my advice based on that question mate.
@@chris4536 haha, yes, but that is not what i meant. i asked myself if i should connect an already filled hose to minimize the amount of air that gets into the system. in the end i just connected the empty hose a did a bleeding procedure. worked well enough, at least i haven't died yet.
Would have been a good vid if it wasn't for that background music
Hope the next one is quiet, hard to follow with the distraction, just my opinion
Anyone who uses a hearing aid can't tolerate background music. I'm not sure the background music adds anything to the video, so perhaps review its use? Top video all the same, but you could help some person with hearing difficulties if you lost the music. 🙏
No Hacks or Bodges required.
Oh Doddy, we don’t deserve you.
Oh it's easy no problem just follow these steps and you will destroy 3 sets of fittings, waste 2 bottles of brake fluid, cover your garage floor in mineral oil, and your brakes still won't work. Have a nice day.
Leaver ✅ lever❌
Nope
E
I love these! But they're are a tad too thorough 😒
2 dollar piece of tape ..
Great instructions but you should wear some eye protection and gloves while working with the oil...
or just take it to the bike shop
Shame on this person for using those amazing forks on that horrid color way for the frame lol.
