- How often do you bleed your brakes?
Oh yeah should’ve added there was nowt wrong with them and I didn’t feel they needed it. I was just purely in the garage faffing and what not with the bike and thought I’d give them a bleed. It’s no bother when it takes all of 20mins for both ends.
If it makes any difference they are Hopes and Dot fluid.Posted 3 years agoSuggseyMember
Only when they have gone soft because when I stuck them on my new frame I undid the connector half turn and swung o ring joint a couple of mm and a tiny amount of air has obviously got in……bugger…..open reservoir and simple job to do though….on my to do list tomorrow as I trapped my finger behind the lever and bars last week so really got to be sorted 😆Posted 3 years ago
Or a good excuse for brake upgrade time….tell the misses fluids leaking from my brakes so I need some new ones 🙂billybouldersMember
If you’d said Elixirs, no-one would have believed you
My Elixirs, fitted 2010, are the best brakes I’ve ever had. Front one was fine out of the box and the back one only needed bleeding because I had to shorten the hose. Apart from changing the pads neither has needed touching since.Posted 3 years ago
The hope(less)’s I had on the other hand never worked as well as the avids despite regular bleeds, seal changes, piston changes, braided hose upgrades etc, etc.kimbersSubscriber
Try and do em once a year?
In reality longer
got a few set of hopes including my minis from 2002 that are still running sweet had a piston change and seal change myself and once rebuilt by hope
Anyway servicing your brakes;
Well worth it especially after trips to the Alps a season of shitty uk riding and racing etc
It only takes 20 mins and a couple of Quid of fluid,
Just like a fork service really you don’t really appreciate it until you’ve done it!
IMO you’d be foolish not to keep your bike running in top conditionPosted 3 years agobillybouldersMember
🙂 Guess so Nobeerinthefridge. To be fair the levers are getting a bit rattly after 4 years hard use and I don’t dare take them apart (even if I could get spares, which I doubt)Posted 3 years ago
Shimano next I reckon, the deores on my spare bike have always been similarly consistently reliable.carlosMember
Just wondering like, I’m aware you don’t NEED to do it every few months or whatever, just I was bored today with the weather and all, Mrs was out, so thought I’d do it.
Anyway, main reason for the question is why/how does the fluid get so dirty/dark?? I gave the brakes a full strip, clean, bleed etc.. back in late May before a trip to Spain, but today the fluid is a dark grey.Posted 3 years agodavewalshMember
They’re a sealed hydraulic system (unlike a car which breathes at the master cylinder), therefore unless opening the system I wouldn’t expect to bleed my brakes ever.Posted 3 years ago
However, that only applies to correctly bled brakes. IMO the main problem with brakes is poor bleeds (either factory or user) combined with the standard internet forum answer to every brake problem is ‘give them a bleed’.NorthwindSubscriber

built the bike in Jan 2008
let a tiny amount of fluid out in 2012 I think
formula Oro K18s.
How many times should I have bled them?
Service lifespan in cars and motorbikes seems to vary from 2-5 years for dot 4 which is probably not a bad guideline.Posted 3 years agouphillcursingSubscriber
I have a set of Magura Clara circa 2002 that have never been bled. Had countless sets of pads but never felt the need to bleed them.Posted 3 years ago
A set of Juicy 3 that my lad inherited from somewhere could have done with weekly attention prior to swapping out for some so far faultless Deore.pdwMember
the standard internet forum answer to every brake problem is ‘give them a bleed’.
Mine get done when they need it, which is pretty much never, unless I’ve disconnected a hose.
If using DOT fluid, it probably makes sense to replace the fluid every few years as you would on a car, as the fluid will absorb water which lowers its boiling point. Although on a bike, there’s a bladder in the reservoir which should mean no air in contact with the fluid and therefore nowhere to absorb water from.Posted 3 years agorocketmanMember

brakes squeal – bleed them
brakes pads worn out – bleed them
brakes don’t fit – bleed them
Have only recently changed some 3-year old Elixir 5s that worked perfectly from day 1 never been bled. Matey has some ancient Juicy 3s from 2009 just keep feeding them pads. Shimano Deore/XT on the other bikes – bled once when fittingPosted 3 years agodeadkennySubscriber
Unless they are Juicys 😉 (though it’s better to just throw them in the bin)
I’ve even broken the rules and not bled my X0 Trails after shortening the cables. They are perfect despite predictions of doom by not instantly bleeding them.
9 times out of 10 a brake bleed is actually not what’s required. It’s an easy advice to offer though. Chances are it will seem to work as the process of bleeding has you taking wheels off, fiddling and adjusting, possibly pushing pistons back, which is probably all that was needed.
Pulling to the bars? Wheel off, pump brake, push piston back, refit wheel. Often solves the problem. Or it could simply be worn pads and the brake hasn’t adjusted (good ones self adjust properly for wear). Doing the same trick can help, or bite adjuster or just fit new pads. Seen people with exactly that problem but everyone jumps in saying “bleed the brakes!” when it’s just the pads were worn.Posted 3 years ago
