Un even rotor/pad wear

[plumkrazee70]

70Dart with Dr. Diff 73+ disc brakes. The pads don't look like they are clamping the rotor evenly. I also noticed that the single piston of the caliper doesn't sit in the middle of the pad back. (See pic) Not sure if I missed something upon install. Master is manual 15/16 from Dr. Diff and just a drum distribution block (rear discs also.)

There is under 150 miles on the setup as I was in the middle of a 4 speed swap shortly after the front brakes were done. What should I look for?

Is the pad lining riveted or bonded?

Not sure without taking the caliper off. They are the pads that came with the Dr. Diff kit.

Normal, Factory calipers 73+ are the slider type. Single piston.
The inside pad will be thicker than the outboard pad when new because all the primary force is on the piston side of the caliper. That is the difference between single piston type and 4 piston type calipers and the way that they mount.
Single piston calipers are held onto the caliper mounting bracket with a flexible plate across the top allowing the caliper to float on the bracket.
4 piston calipers are rigid mounted to the caliper bracket and the pistons/pads are the only things that move and are centered over the rotor and the pads are usually equal thickness inside and outside.
Factory brakes are economical, performance brakes are more complex, efficient and more expensive.
4 piston calipers have 2 pistons on either side of the rotor so the caliper pistons squeeze the rotor with relatively equal pressure on both sides of the rotor which gives more stopping force.
Is It Better To Have More Pistons In Your Brake Calipers?

The caliper looks mounted to the bracket wrong, It should slip under at the top and set in at the bottom.

I thought the same, it doesn't look quite right.

Dang. Ok. I'll remove it and see if I can remount. I'll report back after the weekend, heading out on a camping trip.

I am running 73+ style disk brake set up with the larger 11.75" rotors. I had the same concerns when I installed my brakes because they look to be off but just make sure that your calipers are sitting in the correct slider grooves on the bracket, and you can peek in to check where the brake pad sits on the rotor. It all looks normal from here

Sure looks like a caliper mounting issue to me also. As said above.

Could this be a left/right issue? I have never a swap like this before.
