This is on my 1987 260E...

I have this high pitch squeak while driving from the right side and also the car pulls very slightly to the right.

Here are some hard readings though with my IR temp gun on each wheel:

FR Wheel: 128F
FR Caliper: 151F
FR Disk: 167F

FL Wheel: 110F
FL Caliper: 131F
FL Disk: 131F

As you can see the right side is much warmer for sure.

You guys think its a sticking caliper or could there be anything else causing this noise?

The pads looked okay and I couldn't tell if one was worn more than the other. They are brand new rotors + pads from last year. The caliper is from a 400E I got from the junkyard (4pot).
