The Giant TCR DISC I've had for the last two years has a front brake line that looks like a skipping rope hanging off the front of the bike. It's way too long. Today I go about fixing this myself armed with the right tools and after watching way too many KZfaq videos on hydraulic brakes (and hydraulic theory.... ok, I was bored!).

SHIMANO TL-BH62 Disc Brake Hose Cutter: amzn.to/377IF0A
SHIMANO TL-BT03-S Disc Brake Bleed Tool: amzn.to/3kZapte

Thank you Shane. I did the bleed but didn’t realise you had to pump the lever to complete the job? So I started again from scratch for the same result! Arrgghh! When I pumped the lever to finish the job all was swell. Your tip saved the day. Thanks again.

Make sure the pistons are super squeaky clean before you push them back to prevent the dirt getting behind the seals. Use cotton swabs and some clean mineral oil and the pistons slide in better as well. These look alright but while you're in there you might as well do it properly.

Hi Shane! Long time follower here. As an experienced mechanic I’ll confirm a few things: I always use the block. But before pushing the pistons in, I try to clean them as much as possible in order to not damage the seals with dirt and particles. - I’d use a spare lenght of regular brake or shift housing to measure the desired lenght before cutting the actual hose - the BBB bleed kit is fantastic for Shimano (but you have the original kit now) - most people will strip the bleed port screw on the levers, be patient and careful :) - (I hate to say it: your bar tape is wrapped backward on the top 🤣) I hope It helps for your next brake maintenance session 🙏🏼 (You can see the BBB bleed tool in my latest video) Cheers ✌🏻

I'm new to bike building but I memorized two things from watching several videos. 1) Before cutting a hose, when measuring the length, remember to turn the handlebars to determine the correct length then 2) keep a little length if you are 140 at the front because if one day, you wish to pass in 160, you would be very happy to have this extra length.

Hi Shane, noticed your lever is still a little spongy after a few squeezes, try cable tying the lever to the bar overnight to firm up the pressure, gravity will take place and any air still in the system will rise to the top and stay there..👍 nice job btw..

I had to do this with my new bike. Not only because I installed a narrower handlebar but also because the brakes where configurated wrongly (left/right vs front/rear) to what I´m used to. I had to repeat the bleading procedure because my shifter wasn´t at the perfect angle to bleed with the bucket on top.

Question: why did you decide to cut the top rather than by the brake caliper? I'm working on changing the fork with a front GRX that threads through the fork. And deciding whether it's easier to thread from the top or bottom. If I cut at the caliper, I thread from the top and give a full bleed but don't rewrap the handlebar. If I cut at the top, I wrap the bar and still have to bleed. I have a set of cable cutters and tube cutters available but not the specific tool.

Hi Shane, thanks for this video. I have few questions 1. Do I need the same tools and parts for a dura ace di2 12 speed ? 2. I only want to change my handlebar from a 40 to 38 which has internally routed cables, do I still need to cut the cables when rerouting internally through the new handlebar? Basically I bought a new bike with dura ace di2 system but came with a 42 cm internally routed aero handlebar, this bar is too wide for me and I want to swap it with a 38cm without bleeding or doing anything else to a brand new system.

Great video! Would however use the method of pushing the fluid through the system. Like shown in picture 4 from www.bikeradar.com/advice/workshop/how-to-bleed-shimano-disc-brakes/.

@@gplama done a bunch of shimano bleeds on both mtb and RS685 road shifters. The good news is that shimano usually lets you get away with a half-arsed effort and still be mostly ok but it will annoy you eventually with wandering bite point. The better news is that a full up,down,shifter grab bleed exactly per the dealer manuals from si.shimano.com is not that difficult and makes brakes simply awesome

Why did you cut the line at the lever end? cutting at the caliper end would have been quicker - no tape to undo & retape!

It'd require a full bleed/un-bubble from the bottom up, I assume. I thought this would be less risky as my first time messing with hydraulics.

@@neilwheel but you would need to do full bleed since you would need to let all the mineral oil out, i guess. The suction would probably hold most of it in but still longer way for bubbles to go and more chances of it trapping somewher.

@@davidkosi7662 never had to do it. like you say, suction comes into play here and you'll be shortening the line, not lengthening it.

You could have cut the hose from the caliper line. Would have made life easier, without removing the bar tape etc.

Clear and concise. I would advise checking hose length and routing by turning the bars back and forth BEFORE cutting anything and reviewing this kzfaq.info/get/bejne/a7OqfMynnNbJp3k.html to improve your bar taping skills. Cheers!

I can shorten the cables on my rim brakes in less than 5 min, no special tools needed (not sure about the air bubbles though).
