Default How to change caliper seals?

My rear brakes haven't been used in years, so I decided to fix em up, turns out they are seized, so I popped the sucker out and the seals were completely shot. I went and bought new ones today and they seem to be a pain to get in. Any tips?

You're talking about the o-rings on the caliper piston, correct?

Its been a while since ive messed with them, but after you get the new o-rings on, put some grease around the ring to help slide the piston back in. You may be able to use a c-clamp to push it back in, or use a socket inside the piston and use a vise to push it in, etc.

Never use grease. Use brake fluid. The grease can cause the orings to swell.
