keithap Posted July 2, 2011 Share Posted July 2, 2011 I was going to replace my brakes today and ran into a problem. I have an 87 GL 4WD. I was able to get the hub and calipers off and swapped out the rotor fairly easy, the problem is getting the caliper piston pushed all the way back in. I have turned it so it can go no further, but it is still sticking out about a 1/4" and it will go no further back. Needless to say I'm not to pleased but there must be something I'm missing. I tried turning, it just spins and doesn't move back any further. I tried just pushing but that didn't work. I need to get these pushed back further so I can get the brakes back together. Thank goodness for a 3 day weekend. The car is sitting on jack stands in my parents driveway until I can get it fixed, hopefully tomorrow. Please help!

idosubaru Posted July 3, 2011 Share Posted July 3, 2011 keep spinning it - it'll eventually go in. it seems like it's not going anywhere - but it is. front EA/ER calipers are *turned* in only, they can not be pressed in. if you did happen to press it in - then you may have broken it as they are on a threaded spindle and can't be pressed in. *also make sure the indentations on the pads aren't hitting the piston face. the calipers are not "flat" - so if the pad has indentations sticking up - it might be hitting high points on the caliper.

keithap Posted July 4, 2011 Author Share Posted July 4, 2011 I went and got the square tool to turn the piston in and it went like butter. Amazing how having the right tool makes everything better. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 4, 2011 Share Posted July 4, 2011 those things are pesky, even with the tools sometimes they aren't friendly. glad you knocked it out. so far every subaru piston i've seen goes back just about flush with the caliper bore.

el_freddo Posted July 4, 2011 Share Posted July 4, 2011 This is the cam gear that requires us to turn the piston to get it to retract. If you've been turning it for ages it means there's some crap in there that shouldn't be there. Anyway, the pic: Cheers Bennie Quote Link to comment Share on other sites More sharing options...
