ejmartin Posted January 17, 2006 Share Posted January 17, 2006 In the process of changing out front brake pads on a 1986 gl wagon and didn't realize I needed a special tool (I have it now) to compress and turn in piston.. So last night before I realized this, I pressed on the piston a little with a big C-clamp!! Does anyone think I might have damaged the threads in the piston??? Thanks in advance!!

Subarian Posted January 17, 2006 Share Posted January 17, 2006 Those threads are pretty hefty. I doubt you did any damage. If the piston turns in OK, you should be fine. Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted January 17, 2006 Share Posted January 17, 2006 No I don't think you damaged anything.As long as the rubber seal around the caliper piston isn't cracked then there shouldn't be anything to worry about.Those calipers are pretty strong.

ejmartin Posted January 17, 2006 Author Share Posted January 17, 2006 Actually the rubber boot around the piston is riped and partially missing?? What now?? No I don't think you damaged anything.As long as the rubber seal around the caliper piston isn't cracked then there shouldn't be anything to worry about.Those calipers are pretty strong.

Subarian Posted January 18, 2006 Share Posted January 18, 2006 The boot keeps dirt away from the seal, but you'd probably find most older Subarus on the road have torn boots. You can get a rebuild kit for less than $10 at Autozone. It's not hard to install. Link to comment Share on other sites More sharing options...
wesley willis Posted January 18, 2006 Share Posted January 18, 2006 i tried the C clamp thing unknowingly as well. i'm still alive, so i'm assuming that i didn't damage my brakes. Link to comment Share on other sites More sharing options...
Ross Posted January 18, 2006 Share Posted January 18, 2006 Wont have done any harm, and you dont need to use the special tool - various other things do the job, a large ROE spanner with a screwdriver through the ring end works well. Linemans pliers work well too. Link to comment Share on other sites More sharing options...
ballitch Posted January 18, 2006 Share Posted January 18, 2006 ya use cresent wrench with screwdriver through the eye end, and rotate clockwise i believe. ~Josh~ Link to comment Share on other sites More sharing options...
wesley willis Posted January 18, 2006 Share Posted January 18, 2006 yep, clockwise, and sometimes it seems like you're turning forever and getting nowhere...this is normal. one of my front caliper pistons takes a rediculous amount of turning to get back into its bore.

Ross Posted January 19, 2006 Share Posted January 19, 2006 Oh, and dont touch the hand brake till youve got it back together, otherwise all your hard work turning the %&** caliper in will be undone! Link to comment Share on other sites More sharing options...
