Brake caliper starting to lock up?

You either have a seized piston, seized slide, or maybe both. Take off the rim, remove bracket, polish/sand slide, re-grease with high temp grease/never seize. If piston is stuck, you prob have a torn boot around the piston. Spray WD40 in to the torn boot & have someone in the car push the brake pedal so the piston comes out, then work the piston back in with a C-clamp. Do this until you feel the pistom coming out easier. When you think you're done, give it another shot of WD40, then pack the hole in the boot with heavy high temp grease. OR Buy a new caliper, haha.

haha thanks, i jacked the car up and it was the passenger front, already have a new caliper on and its working great. Didn't want to mess with rebuilding the old one. Thanks for all the info guys
 
I can guarantee you that that is the wrong caliper. I have been through this so many times it's not even funny. Even if they swear up and down from here to Timbuktu that it's a MSP replacement, they will send you calipers for a stock Protege.

Uhm.... nooo. I just put one in yesterday from Autozone. The calipers from them are just old rebuilt MSP calipers branded as something else.. same stampings on them and everything. Completely identical. That is why they are cheaper, they aren't "new". New seal, slider boots and refinished.

You must tell them it is with MPS Tuned suspension. They will have a few options when looking up in the computer.

Yeah, it is identical, but remember to tell them it is for the MPS tuned suspension as vinnie said
