ive been out there for HOURS!!!

sometimes you just want to quit!!

i cannot get the caliper to get around that little bump in the top of the ebc rear outter brake pad... on both sides

i have pushed the piston in with a clamp but it wont seem to budge any further!

please o please help me

No help here...but I feel your pain, man. Had the same problem...eventually, it just "went".

I know this may sound dumb, But check the obvious. I have forgotten to take the brake master cylinder cap off. It wont let you compress it with this cap on. Just check that. Other than that, It has to compress, You got me stumped?

you need to spin them down like a screw.

I didn't screw the pistons in, I just opened the bleed screw and pushed them in with my hands. My EBC pads fit fine, no problems.

<-----
spinning helps break rust patches and allows the piston to move better

how exactly do you spin them? i always take and just press the cylinder down and put on the new pads. ive never heard of spinning them.

So the e-brake was up and i was basically pushing against the force of that!!!!

Couldnt believe it.

I actaully did the brakes by themselves a week ago and they went on fine so iw a slike ok it must be the rotors being too thick for them all to squeeze on.
What sucks is that i ended up filing down a little bump on the ebc pads (the outter side where it has the green). But i dont think that will affect it. Brakes feel 110% better now, no more vibrating and shaking finally!

Thanx for the responses though

well its kinda a thing i just started going out of habbit cause the newer mustangs have kinda like acuatorskinda hard to explain with out one in front of you. (requires some pliars or this special tool deally) in the which require you to spin the you cant just push them down(I worked at a brake place for a while) On camaros there is two triangluar slits cut on the out diameter of the i would take a pair of needle nose pliars and spin them. I highly recommend opening up the bleeder screw caust it can be a pita when pushing. I would only do this when the pistons where hard to pushin like you would regularly do it just some times rust builds up and dirt and spinning kinda frees it up. if all what I said failed i would rebuild it, or recommend a new one be purchased.

I bet you'll never make that mistake again!

If there is enough junk in there to keep the piston from compressing, then the caliper needs a rebuild, IMO. When pads and rotor are new, there is sometimes little space to fit them together.

Also, if someone had adjusted the parking brake travel at the caliper, that will affect how far the inside pad can go in. There is a small allen screw on the back side.
Here is an adjustment procedure, but it is not too common that this has to be done.
