THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN NO. 91-450-5, DATED NOVEMBER 1991. AN ADDITIONAL
CORRECTION HAS BEEN ADDED AND THE LABOR HOURS CHANGED. ALL COPIES OF 91-450-5 SHOULD BE DISCARDED.
Condition:
Some operators of 1991 Caprice police cars may comment on front brake pad life.
Correction:
Remove and discard both RH and LH side air deflectors for better air flow and front brake cooling. (Reference Figure 1).
Also, a larger wheel cylinder has been released for the rear brakes. This will give more brake pressure in the rear, which should
result in increased front pad life. Replace both wheel cylinders with new cylinders, P/N 18004793 following applicable Service
Manual procedure.
