How often do you bleed your brakes?
When they need it. Which is much less often than most people think. TBH most folks don’t keep brakes long enough for the fluid to need replaced. Most of the time, a need to bleed speaks of an earlier bad bleed (so a need to constantly rebleed kinda speaks for itself 😉 )Posted 4 years agoshortcutSubscriber
Bleed them when they stop working. Or potentially if I have been running the same brakes for years and decide to do an alps trip where fresh fluid may well stop them boiling.
Avid users may tell a different story though as they seem to do a bleed every 5 minutes.Posted 4 years agoalpinMember
have an old set of Deores from about 2006/7 that have only been bled once and that was about 6 years ago.
Shimano seem pretty good in that they don’t need bleeding very often, if at all.
Avids on the other hand…. GF boiled her new Avids last year so i re-bled them. the rear would be fine for a while then go squishy. prob more to do with a crap bleed, but then they are a PITA to bleed properly and seem to take an age compared to ShimanoPosted 4 years agoMintmanMember

Do you only ride uphill? or maybe not at all?
I’m not sure what you’re on about? Playing wtih the callipers did not equal replacing the pads (if that’s the conclusion you’ve mistakenly come to).
I was actually faffing with the angle that the hose entered the calliper (not that its anything to be proud of).
To make it worse I was using Superstar pads in my Avid brakes and I still didn’t explode 😀Posted 4 years agowobbliscottMember
There are only 2 reasons to bleed brakes or replace fluid.
1. Water contamination: symptom is spongy non progressive feel. Fluid change required, and you need to suss out where the moisture is getting in as it shouldn’t.
2. air in the system, symptoms, long travel on lever that shortens when you pump the lever. Fix is to bleed brakes and suss out how air is getting in as it shouldn’t be.
Other than that no need to bleed brakes at all in a sealed system. Cars are not sealed systems so need bleeding every 2 yrs or so. Bikes systems are sealed, so in theory you should never have to bleed brakes or replace fluid so long as your system remains fully sealed.Posted 4 years ago
