I have been having trouble with my front brakes locking up. I replaced the brake hoses and the calipers. I ordered new rotors and pads. When I put tried to put them on, they wouldn't fit on the rotor. It's almost like the pads are too thick. When I matched up the new pads, the one pad is thicker than the other. That may be why the pad won't fit on the rotor. Is that common? Anyone have a recommendation on what brand pads to buy that will fit? Or should I cut my new rotors down?

RAYBESTOS MGD84M Specifications
Friction MaterialMetallic
Pad Assembly Thickness, Inner Overall (IN)0.225
Pad Assembly Thickness, Outer Overall (IN)0.165
Plate Length, Inner (IN)5.610
Plate Length, Outer (IN)5.610
 
I'v run into that i time or two doing brakes in past decades, in my old age.
When using new rotors, and also new pads, sometimes things are just to thick, big, for one another.
Just get a sheet of 80 grit sandpaper on the work bench, and then sand down the new pads to fit against the new rotor.
Easy, peasy. Job done.
 
I have found that the inner pad wears faster than the outer. That's probably why they are different thicknesses.

Are you sure you are pushing the piston all the way into the caliper?

If you look at the specs from other manufacturers are they the same?

Are you sure the pads and calipers and disk are correct for your application?

What I'm getting to is are the front disks OEM to the car rather than a swap?

It is original equipment. The piston is all the way into the caliper. I have found that the specs are different in other manufacturers. I bought another set and we'll see what happens when they arrive. Thanks!

Good idea. I did find another brake pad with a thinner spec. I will try those and if I still have problems, they're going on the belt sander! Thanks!
 
Just for the sake of askin, did you try breaking the bleeder screw open and pushing the piston back?
 
If you do sand the pad try to keep it as square as possible.

If it gets crooked it can / will cause issues
 
Good news and bad news-the new brake pads fit and the rotors will spin now. But, the brakes don't stop well now. And when I step on the gas, I really have to hammer it for it to move. Not sure what's going on here. I did adjust the front band to 72" and backed off 2 & 1/2 turns. Does that need to be turned out more? All the brake parts are new. I did rebuild the 727 trans.I put new clutch packs in it and a transgo shift kit is in it. Is there something else I should be looking for? I can't take it for a spin around the block yet, since I don't have a plate on it. That's next on my list. Any advice would be appreciated at this point.
 
do you have the brakes bled? I've had air in the system that caused the front brakes to lock and not release....
