I just replaced the caliper pins on my 1991 745 in hopes that this would free up the calipers sufficiently to stop the brake pulsing I am getting. One old pin out of the four was bone dry; the others were still nicely greased.

However, after driving for a half-hour or so at relatively high speeds, stopping from time to time for lights, etc., the brakes pulse again, and it is always after driving for awhile and not so bad when the rotors are cool. I touched each front rotor and the driver's side rotor was alarmingly hot, while the passenger's side was hot but not enough to make me swear! (I am using Zimmerman cross-drilled front rotors.)

I have had control arm stays and bushings replaced in the front suspension within the last year. I am suspecting new/rebuilt front calipers may be necessary.

Have any of you had good luck with the Girling jumbo calipers from FCP Groton? IPD doesn't list any for my year (1991) and their prices are significantly higher.

Thanks for the help.
