BRAKE SYSTEM 511 BRAKES TROUBLESHOOTING AND DIAGNOSIS Before doing actual repairs on brake system, perform preliminary checks of the system as follows: 1. Road test the vehicle on dry, clean, smooth and reasonably level roadway. Apply brakes with heavy and light load application at various speeds to determine whether the vehicle stops evenly and effectively. 2. Also while testing, check if the vehicle pulls to one side with and without brake application. If so, check t ire pressure, front end wheel al ignment, suspension joints and mounting fasteners. 3. Check TMC fluid level. If found below minimum (which indicates the leak in brake system) check the entire system for leakage and replace the defective parts. 4. Improper brake fluid, mineral oil or water in the brake fluid may cause brake fluid to boil or rubber components to deteriorate. If deterioration is found, disassemble all hydraulic parts and wash with alcohol. Dry these components with compressed air before installation. 5. Perform a visual inspection for following: (a) Brake shoe thickness (b) Crack or pinching of brake hoses (c) System leak (d) Damage to components like TMC, Booster, Wheel cylinder etc. (e) Proper clearance between brake light switch and brake pedal.
