BRAKE SERVICE PROCEDURES FOR 1991 GEO Tracker AUTOMOBILES
DRUM BRAKES, GENERAL MOTORS -> General Information -> SERVICE PRECAUTIONS
Vehicle: 1991 GEO Tracker 1.6 L4 GAS
When working on or around brake assemblies, care must be taken to prevent breathing asbestos dust, as many manufacturers incorporate asbestos fibers in the production of brake linings. During routine service operations, the amount of asbestos dust from brake lining wear is at a low level due to a chemical breakdown during use, and a few precautions will minimize exposure. Do not sand or grind brake linings unless suitable local exhaust ventilation equipment is used to prevent e...
