Help with rear brakes, what am I doing wrong? Options

[Kevin@ojai.net]

So, a few minutes ago I tried replacing my rear brake pads with out success. I was unable to retract the pistons far enough into the calipers to fit the new pads in. All I did during my failed attempt was remove the old pads, then pry against the pistons. This process has worked for me on other vehicles, but I had almost no luck on the 914. I was able to retract the pistons a little, but not nearly enough to get the new pads installed. What am I forgetting to do? What am I doing wrong?

(IMG:http://www.914world.com/bbs2/html/emoticons/agree.gif) Dave did a brain dump on you. READ IT. All good advice. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I seriously doubt you'll be able to get the inner adjuster cover off with just the 4mm. If you want to attempt to put in new pads without pulling the caliper then I would suggest a MAPP torch on the rear adjuster before you even "attempt" its removal. Once you get it off you should be good to go. Use a long socket extension and a 4mm hex socket. If you can't get it then plan on Dave's route of removing and benching it. Plan on bleeding etc. (you and the car) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

It would probably be best to remove the brakeline clip and at least take the 19mm's out to remove the caliper. Good time to inspect the dust cover boots as Dave suggested. They are the #1 cause of stuck pistons (those and shitty brakefluid) as a torn one will allow water in to rust the piston top and bore.

You're in for a dime right now... the dollars come quickly. On a positive note, most pistons will move if done properly. Can they work better with a rebuild? Sure, but you should be fine if you can get them adjusted. Good luck.
