New disc calipers and pads won't go on rotor
Replacing my calipers and can't get them to slide over rotor. I compressed the piston as far as it will go but still won't slide over rotor. Checked calipers and pads and they're identical to the new ones. Notice a thin steel "shim" on the back of each pad, even tried to put pads on without them. I used a c clamp and an old pad to compress the piston, looks bottomed out. Any ideas?

Never mind, I'm an idiot! Was using two inside pads!

I was going to say somebody sold you 1'' rotor parts.
But this is way better

We all have been there done that! If you can't laugh at yourself you have no business laughing at others!

Re: New disc calipers and pads won't go on rotor
I just came across the same thing.
New calipers,hoses and pads for the front of my 71. Drivers side went together fine. On to passenger side and i couldn't fit the loaded caliper over the rotor. Turns out this one caliper is about 1/4" narrower and don't fit. Now I gotta reorder another.

Re: New disc calipers and pads won't go on rotor
I did that once. I was taking my car in somewhere, got the call a spot was free, had my brakes apart to measure the axle flange, and "threw everything back together" without even a trouble-light. Big mistake.
Didn't make a horrible sound, didn't really drive much different (it was just a couple of miles) but MAN did I feel like an idiot when they saw it! Then I came on here and told everyone just now :-P It happens...
