Piston won't compress on rear brake caliper
Piston won't compress on rear brake caliper
Anyone familiar with a problem just compressing the piston on the rear calipers? I opened the bleeder valve and only get fluid out from the line, not the piston compressing.

Looks like you have a case of the siezed piston. This is common over time and use. You can either replace the whole caliper unit or try and rebuild the caliper yourself. You will get fluid out the bleeder valve, but this doesn't affect the piston being stuck.
Good luck.

get some needle nose pliers and turn it clockwise while firmly pushing it in.
shouldnt need too much effort actually.
oh and make sure your reseviour cap is REMOVED or it'll be trying to pressurize inside of there, making it near impossible to push in.
If it is a stubborn b----, use some visegrips on the very tip of the piston (try not to grab the boot or anything) and then try to turn it and move it inward...once its free-up some it should move a lot easier.
sometimes rust forms on the outside of the piston and cauese it to be a b---- to move in and out

This only works if you have the rear calipers designed for the 323. Some of the MX-3s have genII RX-7 rear calipers which is the type being discussed here. These calipers the actual pistion has to be screwed back in instead of having a retracting screw on the back.mx3autozam wrote:OMG guys. I'm new to MX3's and know this
Remove the 13mm bolt on the rear and use an allan key to turn it back in
There is a third type of rear caliper that I have seen on a few '96 these are worse that the 323 screw retracting type for jamming and not working. Never actually tried to replaced the pads on one of these. The last time I saw one of these 5 years ago they were so far gone that the calipers needed to be replaced along with the pads.
