What would be your approach at fixing it....Just taking the caliper off, cleaning it up and then just re install or?????

I now have theme torn apart a bit....Well the drivers side front caliper is off hanging from a coat hanger...I took the pads off, but everything looks ok to my eye....


I just had a brake job done two seasons ago (less than 10k mile) so I didnt expect the pads to look bad....


Im stumped.... Why would this be happening and does anyone have a plan of attack that they would take lol.... I need some sort of a tip....


Also..... Should my rotor be able to spin freely with my front end lifted off the ground and my tires off....I thought they should seeing as thats how the wheel moves but I didnt know If anything electric locks it up when the car is off :confused:
I noticed BOTH front rotors wouldnt spin and now that I have the one (drivers side front) caliper compressed that rotor will spin like I thought it should.....


Are both my front calipers somehow locking up??!??!?

Hey not for nothing but if you don't know what it is n don't know what to do I suggest you get it checked by someone who really knows or a perfessional shop cause dude brakes is not something to mess around with get it checked before you wreck something or someone you love.

could be the caliper pistons sticking/freezing

same thing happened to my original calipers

but first check the caliper slide pins

remember the bolts you took out to remove the caliper?
well the part they thread into actually slides into the caliper bracket

you'll see a small rubber boot sealing the pin to the bracket

try to remove the pin from the bracket, if it doesn't slide out with little effort, thats your problem

get them out and clean them up very good with a wire wheel or some coarse sandpaper and then coat with grease or neversieze and reinstall

also, push the pistons back into the caliper (you may have to rent/buy a brake caliper tool for this), if they go easy your calipers are fine, if not, consider replacing them. they can be rebuilt but imho it not worth it. they always seem to be troublesome after a rebuild

also, you should really pick up a haynes manual for you car. they are less than 20 bucks and will guide you step-by-step much quicker than waiting for people to reply online when you have a problem, which in turn will get you on the road and having fun again much sooner


hope this helps:)

ps. nothing electric will lock up your brakes and you will have no light on the dash for brake problems unless it a malfunction with the abs.

also, even when everything is working as it should, there will be resistance to spinning the caliper, it'll spin with minor effort but don't expect it to freewheel like a bicycle wheel

again, i hope i've helped:)

Then Yes they are PBR, look on the top of the caliper it even says PBR. Its common on them... the pistons corrodes in the caliper. Try to compress a piston if it dont move or moves very slowly with a lot of force needed thats your problem. But check all 4 pistons

SO THE SLIDE PINS WERE FINE AND THE PISTON ARE CORRODED INSIDE....(sorry about caps lock lol)


What is suggested to be done about it.....The remains that you mentioned Mnirishjr, are they just to rebuild the caliper???? Im not sure If I wanna go that route and just have it happen again.... this SUCKS!:thumbsdown:
