I got the rear brake pads put in my 4 lug rx7, into the caliper bracket, but now my problem is I can't get the caliper to fit back over onto the caliper bracket itself....Any help?

 

you have to "push" the piston in....... you have to turn the piston until its far enough in! you cant push in the piston

 

I turned the piston in with a needle nose all of the way but the outter pad seems to stick out a little to far and I can't get the caliper to fit over it.

 

For what its worth, go to NAPA and get a caliper piston tool. Its a little cubed deal with prongs.It firs a 1/2 " socket. It is a universal type so you will have to figure which one works for you. With that you can easily move the piston enought to clear.

 

The piston is all the way in. My problem is the upper mounting pin, I can't get it to move in or out to guide the caliper around the brake pads. It has to move toward the outside of the car about an 1/8 of an inch but it just won't budge.

 

Are you sure the piston is on the correct position? There should be one or two 'nubs' on the pad that fit into the recessions on the piston. If they are not lined up, you will have a gap.

 

Yeah the pads are in place as far as they will go but I can't get the upper mounting pin, that holds the piston assembly in place, to move even with penetrating oil it still wont move. Is there something I am missing that I have to take out to pull out the upper mounting pin?

 

Guess I do not understand why you are messing with the upper pin. You only need to remove the lower pin (lock pin bolt) pivot the caliper upward and support it with something. Then remove the pads. The bolts holding the caliper to the caliper mounting frame are mightly torqued on. It sounds like you are trying to remove them. Only remove them if you are replacing the whole caliper assembly.

The clearance between the piston and the pads will me tiny. Follow the suggestions above and make absolutely sure they are in fact compressed as much as possible. You will for sure get more twists from the tool than you will from needle nose pliers. The NAPA tool is only $10.00 You might also check to make sure the shims are fitting snug to the outside pad surface and that the seperator clip is in fact holding the pads apart.

 

No, the piston was turned all of the way in but the upper mounting pin is froze so it will not move in and out to adjust to the thickness of the new break pads. I could not get it to move or break loose so now I figure i might as well buy a new caliper.

 

Stupid question here. So plz no flaming. Is your ebrake on?

 

that has nothing to do with it. ^

 

Hit the pin. Hard. With a hammer. Repeatedly.

I know exactly what you're talking about, and spent about half an hour staring at my brake pads looking at the same thing. It's just stuck. You really should pull it out, and lube it again, but a hammer is a good start for getting it to move.

Speaking of which, I need to go pull my rear calipers off and free those up properly.
