help calipers stuck
both of my rear brake calipers appear to be stuck i cant push the piston in to get new pads on im using a c clamp to do this..
whats the best and cheapest way to possibly unstick them socking them in somting like kerosene? |
head to autozone the pistons are threaded and you need a tool
|
Make sure the e-brake is off...
The pistons are not threaded. |
i had to turn my pistons to push them back busted a clamp trying to do it normal way
and had to get a special tool to do so mine is s5 don't know of any differences in rear brakes though |
Don't use a c-clamp! You have to rotate the rear pistons to get them to go in. The easiest way is to use a pair of needle-nose pliers to grab onto the end and spin it.

oh spin it sweet maybey mine arnt stuck then
|
You need to rotate the rear pistons to move them back into the caliper body. I generally juse use a set of needle nosed pliers...
All this information is in the Haynes/FSM. The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars. Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well. These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download. |
HEY CARMEN!..I saw a thread on this a little while back,and it Actually has a PIC of the Brake block tool that you need to Turn the Caliper back in.(looks like a Small Cube,an Inch or so Square,and has Dimples coming out of it to go on the Caliper face so that it Turns it in..it Attaches onto a 3/8 Drive Socket Extension).you CAN'T Squeeze it in with a C Clamp!.....So in Short..do a SEARCH,you find it!
|
That little cube in the previous post helps a lot, but I use the needle-nose pliers...remember not to accidentally stab your hand if the pliers slip off the piston. Also...opening the cap to the brake master cylinder helps.
|
try using a open end wrench that fits snug between the openings of the piston, then attach a vice grip to it for leverage and turn it clockwise. Since my local store did not carry such tool, i had to improvise and the pliers weren't strong enough to turn it. Good luck:)
