1995 P32 Rotors Overheating

I have read ceramic does tend to put more heat in the rotor as it does not conduct heat away like semi-metallic. You can pull a wheel and see if the caliper is frozen to the mount. +1 for checking the rears and full pressure bleed and fluid replacement.

Doubt the linkage pic above is any issue. Looks like four bolts and the gold bracket would come off the black frame bracket.
