    So I have just changed the pads on my XOs. The rear was fine but the front has lost all power. I removed the old pads, re-set the pistons, fitted the new pads and the lever now just pulls to the bar. It looks like the left side piston is not moving. Have I buggered the piston or do they just need a bleed?

    Any help would be appreciated as I am at Mayhem this weekend!

    Cheers

    Was the bike upside down when you changed the pads? If so, they probably had air in the reservoir that’s now in the system.A good bleed should remove it, and prevent it happening again.

    if they are 2013 X0 trail brakes make sure the pads are not jamming in the caliper, i had the same issue but it sorted it’s self one i freed the pad off.

    Just to add to this, I’ve got 2012 Avid X0s and had lever pull to the bar, turned out to be a seal that had blow in the caliper. Can you see air bubbles coming from the caliper when you squeeze the lever?

    They’re warrantied for two years, so send them back if that’s the case.

    The bike was the right way up and they are 2012 XOs. I am getting some movement of the pistons but not much before the lever touches the bar. It feels like it needs a bleed but I cannot think why it happened all of a sudden.

    Looks like I will be pleading to the bike shop workshop tomorrow.

    Rickon,

    Cheers. I cannot see any air or bubbles anywhere. I will try the LBS tomorrow and have panic bought a bleed kit just in case.

    Did you buy one from Epic Bleed Solutions? If so… good choice 😉 It’s handy to have a kit anyway.

    Rickon,

    Yep, Epic got my order. Just hoping it arrives in time!

    It’s almost certainly had air in the reservoir- backing off the pistons moves a load of fluid around, when they’ve moved back out they’ve brought air in it. Bad bleed from the factory that’s just been waiting to cause you trouble. Not specifically an Avid fault though (on this occasion!)

    Similar issues here tbh.
    Changed pads on front XX and pulled to the bars repeatedly 24hrs later it had sorted itself out and was fine.
    Just changed rears pre-mayhem and I’ve got the same issue.

    What do Sram expect us to do if you’re on an epic and need a mid ride pad change? Not happy.

    Strangely the rear was a bit soft and has now firmed up. I will see what it is like in the morning.

    Well, a tour of three German bike shops resulted in one that was willing to take it and get it fixed before I get in the car and drive to the UK tomorrow for MM. Fingers crossed he can get it sorted. If not I have a bleed kit on order and access to another and apparently AVID will be at Mayhem so I might be approaching them with a big box of biscuits on Saturday!!
