SYSTEM
The function of the Anti-Lock Brake System (ABS) is to minimize wheel lockup during heavy braking on most road surfaces. The system performs this function by monitoring wheel speed and controlling the brake fluid pressure to each front wheel and both rear wheels during braking. This allows the driver to retain directional stability and better steering capability.
1993-94 Eldorado, Seville & DeVille models with the 4.6L Northstar engine are also equipped with a real-time traction control system (TCS). The purpose of the traction control system is to prevent excessive wheel spin ...

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 excessive asbestos exposure.
- Wear a suitable respirator approved for asbestos dust use during all repair proced...

SYSTEM OPERATION
Front & Rear Split System
When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective systems, Fig. .
If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.
If the front (primary) brake system fails,...
