Hey all,

So I'm redoing my pads and rotors, but I can not seem to get the caliper piston to compress fully.

I moved over to the driver side, and it compressed a bit more than the passenger side. I am still unable to fit the calipers over the new pads on either side.

Recently I have noticed lack of stopping power, and it pulls to the right when braking.

I am planning to replace the passenger caliper, but just wanted y'alls thoughts on it.

This is my 1st muscle car and i'm used to working on newer vehicles, so there is a learning curve for me.


I appreciate everyone's help and support. Thank you

Piston/bore interface is most likely rusted/coroded.. can sometimes be saved by replacing piston and addressing rust in bore, but really depends on the extent of the internal damage..

From the looks of the caliper, I would just replace the calipers on both sides. Also the lines if they are in bad condition. For my 71 I went to Chockostang and he had a package that included, calipers, rotors, pads and lines for a reasonable price.
^ What he said. I can find no thickness specs on the '70 pads (other than the pressure plates themselves @ .190"),
so I'm going to assume the pads are probably ok for thickness out of the box and the calipers themselves
are the issue.

Thank you ! I was thinking the same. I picked up 2 new calipers, and will be installing them today. Thank you again !

Piston should retract flush with the caliper face, the inside of the bore is rusted or has junk in it. Time to replace them. $25 each at NAPA and it appears they include new hardware.

Make sure you don't mix up left and right. The bleeder must face the rear of the car when installed, not point upwards.

Yeah that was exactly what I was thinking. That is the way it is with every other caliper. I just wanted to make sure I didn't miss a step.

Regardless of the car its not uncommon to have to compress the piston with a c-clamp...I am assuming you used one first? That being said, it does look like they needed replacement in this case
