  • Touring with hydraulic disc brakes

    Has anyone done this? When hydraulics go wrong, how easy are they to fix miles from anywhere with no tools? What is most likely to fail on a hydraulic set up? Off around ireland next uear and Interested to hear from anyone with practical experience. Thanks!

  • I've had the O-ring where the hydraulic line meets the rear calliper fail somewhere in rural France. None of the bicycle shops within 30km had that O-ring so after the third descent without a rear brake I called it quits and caught a train home.

    I have to say, this was about 4 years ago. Hydraulic road bike disc brakes weren't a thing at the time. Nowadays more shops would probably stock the right O-rings for Shimano brakes. Also since that incident I haven't had any issues at all with my brakes.

  • Ok, so maybe pack a couple spare o rings. My main worry is, if something catastrophically leaks, where will I find brake fluid? Could I use olive oil or something?
