rear brake pads cant fit

[bergspre]

Hi, the piston seems to be too far out for the brake pads to fit. How can I get the piston in again for more space? (i havent touched the brake)

Hi
I left the old pad in on the piston side and used a set of water pump pliers to ease it back, squeezing on the pad and caliper, you need to protect the caliper with a thin bit of wood to stop it getting marked, or you could leave the old pads in and lever between them with some strong screwdrivers, it's worked for me every time.
Best of luck.....

Thanks, i got it back now. But now i cant get the pads in, its just not enough space on the back side of the brakedisc, between the brakedisc and the caliper body..the caliper body wont be able to be taken down into place.

I use a clamp like this:

works perfectly. Maybe your caliper isn't moving where it supposed to move? Some pictures pointing out the problem would really help.

yep.
For instance, is the caliper single-sided? (A piston on one side only).

I assume it is.

In which case, the whole caliper slides side-to-side on two pins, underneath little rubber gaiters.
Sometimes when you change the pads, specially if it's a long time since they were last changed, the caliper seizes on the pins. But it's usually easy to free off.
So if the caliper isn't moving side-to-side, you'll need to work out how you remove the caliper from the pins. Sometimes they unscrew from the caliper-holder, or there might be some clip arrangement.
You'll need to clean the pins - there may be rust there - and grease them carefully.
Don't damage the rubber gaiters.

A close-up photo or two would help, both sides of the caliper.
(Or the exact model of bike, probably someone here will know the procedure straightaway).

Its a XT600E year 2000
I can take some pictures today. Maybe its necessary to take off the whole caliper body and clean it..i dont like the idea of having to bleed the system cause ive never done that before, so thats why i havent taken it apart yet.
