mulcheese Posted February 21, 2009 Share Posted February 21, 2009 1997 Impreza OBS Do I need to remove the entire caliper or am I able to replace the pads by removing one pin and rotating the bracket up? I have searched and some indicate the calipers may need to be removed. Link to comment Share on other sites More sharing options...
davebugs Posted February 21, 2009 Share Posted February 21, 2009 (edited) I always remove them to lube things up, check the boots, etc. Just hang the caliper from a wire running to the strut spring. If you're that far into the job you wanna check the slides, etc in my opinion. Edited February 21, 2009 by davebugs typing abilities Link to comment Share on other sites More sharing options...
bratman18 Posted February 21, 2009 Share Posted February 21, 2009 I agree, you don't have to remove the whole thing, but I always remove everything, even the caliper bracket, just to lube everything up. Those caliper bracket bolts often rust in there really good, so it's good to take them off, clean 'em up, lube 'em and then reinstall. Link to comment Share on other sites More sharing options...
idosubaru Posted February 21, 2009 Share Posted February 21, 2009 definitely remove and grease the slides. it's really, really easy anyway. Link to comment Share on other sites More sharing options...
PAezb Posted February 21, 2009 Share Posted February 21, 2009 You might want to consider purchasing the reseal kit for your vehicle. Around $20 (per axle) from a Suburau discounter. Given it's age, might be time to replace all the boots and piston seals. Easy enough to do while you're working on the brakes anyways. Link to comment Share on other sites More sharing options...

Instead of hanging the caliper from a wire, I find a small cardboard box lying around, and just lay the caliper on top of the box. The result is the same. You just don't want the caliper hanging by the rubber brake line. Link to comment Share on other sites More sharing options...

Any special tools or special skill needed to replace the boots and piston seals? I have never done this, and would like to learn when I do the brakes on my Subie this Spring.

davebugs Posted February 21, 2009 Share Posted February 21, 2009 Boots are easy - just require a little patience. I get generic ones that come in a black box. Never even priced original parts for this. I just keep a box (or partial box) around. Piston seals I've never done. If there is a problem there I just install a reman caliper.

mulcheese Posted February 21, 2009 Author Share Posted February 21, 2009 One more question. Is the piston seal a dust boot or does it actually keep the brake fluid in the caliper. To put it another way if it does go bad and fail/crack will my fluid leak out? Link to comment Share on other sites More sharing options...
OB99W Posted February 22, 2009 Share Posted February 22, 2009 A failed piston seal will allow brake fluid to get past it, but it might not be obvious if it's just starting to go bad, since the boot can retain some fluid. Neither the piston seal nor the boot is difficult to replace, although care has to be taken to avoid marring surfaces. However, scoring or pitting of the piston and/or bore (often due to contaminated brake fluid) can also cause leakage, and a new seal won't resolve that.
