Ok guys here it goes. I have a 2003 rm 85. With a ton of mod's. I recently bout new back brake pads and removed the old ones off the bike. I removed the calliper of the frame and put the new pads in, put everything back to gether. And now the calliper wont come out. I bleed the hell out of the line the only i did was comprees the piston in the calliper to remove the pad. Now for the life of me i cannot get the piston to come out when i press the brake. It acts like it wants to come out but it barley moves. The seal are good Ive checked them. I must be doing something wrong. Any help guys? thanks
