This is why I don't like closed off style wheels.... i can't tell how the brakes are doing.... So I was swapping wheels this weekend and found the following. At first I thought "OK, a seized caliper" but both sides look identical !!!
Re: Rear calipers aren't "squeezing very hard" ??? (CoconutPete)
that is not normal. and neither is the level of rust in my opinion. you may have a rusted piston in the caliper. in conn i would bet they still use salt. and if they do one needs to rinse the underside/brakes/etc of cars regularly.
i think you would be best to get new calipers, or at lest rebuilt ones. i would not even try to clean those up. the hardware and parts are pricy i think. you might not even get core value on trade-in either.
ask jrl for his opinion and or suggestions. edit, he prob has similar conditions.
just my opinion. i have never had pads that did not make full contact/sweep of a rotor, so i think you got to deal with it from the ground up.
i have used fcp groton. they do very well for these parts. right now they have free shipping for orders of 99 bucks or more. i just got an e mail also offering 10% off with their "junebug" coupon code.
rear calipers were 139 new, and 58 for rebuilt with a core charge of 50 bucks each. they may not like yours though, so call them before you decide.
i would buy new, with ceramic pads, often the rebuilt come with pads though. your rotors may be ok and clean up with working caliper and new pads. that is just a thought of course.
ipd is another great source.
good luck. think of changing your brake lines too. along with a complete brake fluid flush your getting in to a complete overhaul that appears needed.
Well if all works out I should have access to my buddys shop this weekend. Going to flush out the brake fluid and yank everything apart and see if I can clean it up to get an idea of what the hell is going on back there.
Does anyone happen to have the torque specs for the brake calipers?
