hey guys im in need of a little help with my rear disk brake (avid juicy three) i somehow lost one of the brake pads and the piston has moved over towards the other pad (does this mean i have to bleed the brakes which i have no idea in hell how to do) would a bike shop be able to fix this problem for me? also any recommendations for a good bike shop to sort these kind of issues in kerry would be very welcome.
ive added two pics of the brake maybe ye can tell me whats wrong (also havnt noticed any fluid leaking from the brake caliper and i also have brake pressure as the brake is working just not great as im missing a pad)
You should be able to remove the other pad and then very carefully insert the tip of a screwdriver between the pistons and twist gently forcing them apart. It would be easier to do this with the caliper removed from the frame. But if you are not confident I would let a bike shop do it - any competent shop will be able! By the way that pad is shagged!!
thanks for the reply, some other fella i was asking told me the piston with the missing pad might be completely shot as i used the bike this morning before i realized i was missing a pad (had two yesterday), the bike was bought used so i know some little parts will need replacing (pads are cheap enough but if i made an arse of the brake piston things could get a little tricky), il try to do what you told me anyway
I was going to suggest something other than a screwdriver for pushing that piston back, you don't want to damage it, then I realized that piston is so far out it must have been on the rotor! Did you hear a feint metal on metal sound at all? What state is the rotor in?
Sean,
If I remember right there is a central protrusion on the Juicy's pistons to help hold the pads in place. It is most likely not there now anyway. The pad might have fell out and the protrusion broke when it met a hole in the disk (very unlikely) or it broke earlier fitting or removing the pads (more likely, I have done this, Doooh!) and the pad fell out because it was only relying on the spring clip.
Either way I think you would at least need a new piston to be safe.
yeah i did hear it so im pretty certain the rotor is shot (but i dont know how to tell :() whats the cheapest thing to do? buy a new brake set and get some guy to install it or buy new pads and a new rotor and get a guy to install it (im no where near being able to do this myself yet im getting there but not yet :))

yeah id say the rotor filled it down until it was gone (early morning + earphones = ignorant bliss ;D) was doing some messing around in a woods near my house for the last couple of days so thats where i lost the pad id say oh well i was looking at upgrading the bike bit by bit might as well start with the rear brake (do all disk brakes fit all mtb's? whats with the different size rotors?)
It also looks like the disc has been rubbing off the brake adaptor! I'd check the spacing of the brake caliper in relation to the brake disc, doesn't seem right at all. Must be making fierce noise.
yeah i noticed that as well although its not really making all that much noise, damn it im going to save up for the week and buy myself a new rear brake, was all working great as well until the smart man i am decided to take it off a 3 foot drop :) guess il be replacing a lot of parts so, also the rear brake seems to be working right now (even though im missing the pad and its probably destroying the rotor and piston) so im going cycling on it tomorrow feck it
