  • XT rear brake.. Bled well, no leeks but still not good.. Options?

    So they’re in good shape.. The lever was recently replaced and by Merlin cycles and then they were checked over. I bled them a month ago and spent hours leaning, flicking etc to get every last bubble out..

    I checked them a few days ago and one or two little bubble came out but not enough to concern me.. The pads are new, the brakes work but the bite point keeps changing.. Sometimes a little closer to the bar than I’m happy with.

    What are my options to sort this? Pistons damages, dirty Pistons, new stiffer hoses??

    So tempted just to give up and buy some hopes!

    Did you take the caliper off and bleed that with a syringe?

    Have you checked for any other vegetables?

    How old/worn is the disc rotor? Ive found that can play havoc with shitmano brakes.

    If the bite point is changing (and not always moving in the same direction) then the most likely culprit is air, i.e. your bleed wasn’t as successful as you think.

    Apply some cheese sauce and a little paprika.Works for me every time. 😀
    Seriously though just fire it back to merlin.They’ve replaced both of mine as mine too where haunted by wee gremlins.

    It can be hard to get all the air out the caliper especially if you’ve been bleeding it still on the frame

    use a zip tie to hold the lever down all night and the air should move to the lever then bleed from that.

    Does it still happen if you’re riding in Wales?

    zip tie idea sounds good.. With the cap off or on..

    just pull the lever hard and put the ziptie on to hold it there. you want the system under pressure to force the air up.

    The vid below shows how to get a decent bleed

    Are the rotors knocking the pads back ? If the rotors are deformed they’ll push the pads back into the calipers. This causes long lever travel and it’s overcome by pumping the brake. Pump the lever quickly several times in quick succession and see it the bite point comes further out.
