This informative booklet includes all the information Buick put out for trouble shooting the problematic 1985-1987 Turbo Regal powermaster brake system. We even include the information on the Dealer Service Bulletins and the Dealer Product campaigns. One of the first recalls was of course the issues with the black brake switch. The replacement one is gray. The last brake bowl design was the version with the yellow wording. The only one available today brand new is the larger plain black bowl.
The key to have a long lasting properly working powermaster brake system is to make sure you flush the brake fluid every 1-2 years or when you notice it is very dirty.
This booklet has 70 pages of useful information concerning the powermaster brake system.
