How To Fit & Set Up Shimano Road Bike Hydraulic Disc Brakes | GCN Tech's Full Setup & Installation

Hydraulic road disc brakes offer superior performance but can be a little more complicated to set up than cable brakes. Ollie gives us an in-depth guide on the installation, setup, and maintenance of hydraulic road disc brakes. This video covers the tools you will need and the process of running cables and hoses through internally routed frames.

From my calculations Ollie used $1039.40 USD worth of Park Tools to install this $550 USD hydraulic brake set. However, we cyclists seem to loose all sense when it comes to spending on our bikes. Case in point I just spent an extra $120 on a some pedals just because they are a few grams lighter than the ones I had been happy with for 8 years.

This tutorial was absolutely what I needed to walk me through my first installation and setup of Shimano hydraulics. Clear instructions, great video to follow along, and one of the best instructors you could ask for. Thank you so much!

[MikeSmith-quew]

That was perfect! I have to do this and been watching many demonstrations and you have a real skill in communication. The experience and positive skill you have show clearly you are a serious cyclist. thanks from an old person that needed a good demonstration!

ALWAYS push the olive and nut onto the hose before installing the barb. Most barbs are to big to slide an olive and nut over.

Best advert for mechanical brakes I have seen

[elorz]

You can also very easily just hammer the barb into the housing with a pair of pliers and the yellow blocks that usually come with the brakes.

I was considering swapping out my shifters and brakes, and this video gave me the confidence that I could do it myself. Thank you.

Great video GCN. I’ve been intimidated about disc maintenance. Feeling confident now.

Note that the "wedge" flatmount adaptor for 160mm rotors for the back calliper doesn't usually come with the groupset whereas the front one usually does. Just a heads up if you are buying components to build your own bike.

I just love my colnago master with rim brake and external cables!

[stuartpatterson]

Olly, I noticed that you did it, but you never mentioned why you had the crows foot adapter at 90 degrees to the torque wrench. If anyone is wondering, it keeps the effective length the same, and therefore the torque the same (or near enough, it's not a perfect method, but close enough).

Great video. I would make a few additions. Firstly, it's just mineral oil and not brake or hydraulic fluid (which is corrosive) so not much to worry about when dealing with it. Also, for internal routing I find doing the opposite (getting the levers connected and then cutting the hose to length at the brake itself to be easier. Best video I've found on this... Thanks!

[usaidadnan]

This is just perfect as I just bought a gravel bike that had mechanical disc brakes and I want to upgrade to hydraulic brakes

[JohnAlexanderCain]

In the UK, they drive on the opposite side of the road and use the opposite brakes levers, right is front and left is back. Wah Wah. Thanks for informative video, bike dudes. Great entertainment for this rainy winter night.

Recently bled my brakes and had the black bar on the syringe positioned the same way as seen at 16:20 and was (unknowingly) slowly closing the bleed port back up. You can kind of see that happening in the video. Created a few issues for me before realizing what was happening.

[fluketennis]

thank you so much for sharing, I am a completely newbie in biking. Hope I can do DIY maintenance. Thanks again

[kjhlvco]

Perfect. Clears out many misconceptions i had. Thanks!

[oheso]

For a GCN video, that was surprisingly clear and complete. Well done and thank you!

[JP-mofb]

Clear, concise and plenty of helpful hints to future proof an installation. Thank you. J

Installing a new 105 groupset into my Orbea bike and Ollie just answered all the questions I had and any that may arise later. Thanks for the wonderfully detailed video!!
