Cadillac DeVille 1994-1999 Brakes Specifications

The 1994-1999 Cadillac DeVille features front disc brakes with a diameter of 11.0 inches and rear drum brakes. The brake system utilizes a vacuum-assisted power brake booster with a dual-circuit master cylinder. The front rotors are ventilated for improved heat dissipation, and the rear brakes include a self-adjusting mechanism. The brake system is compatible with DOT 3 brake fluid, and the recommended brake pads are designed for semi-metallic or low-metallic formulations. The wheel bearings are grease-sealed, and the parking brake operates via a separate cable-actuated mechanism.

Regular brake maintenance for the 1994-1999 Cadillac DeVille includes inspecting brake pads every 12,000 miles, checking rotor thickness every 24,000 miles, and bleeding the brake system annually or when air is suspected in the lines. Brake fluid should be replaced every 30,000 miles, and the brake fluid level should be checked during each oil change. Rear drum brakes require adjustment every 12,000 miles, and the parking brake cable should be inspected for wear and lubricated as needed. All maintenance should follow the procedures outlined in the GM service manual.

To replace the brake pads, start by raising the vehicle and removing the wheels. Remove the caliper bolts and slide the caliper off the rotor, taking care not to damage the brake hose. Remove the old brake pads and install the new ones, ensuring proper alignment. Reinstall the caliper and tighten the bolts to the specified torque (80-100 ft-lbs). Repeat for all wheels, then bleed the brake system to remove any air. Test the brakes by driving slowly and applying gentle pressure.

Common brake issues include spongy pedal feel, grinding noises, or reduced stopping power. A spongy pedal may indicate air in the system, requiring bleeding. Grinding noises often result from worn brake pads or warped rotors, which need replacement. Reduced stopping power could be caused by a brake fluid leak, which should be inspected and repaired immediately. Always check the brake fluid level and condition, and inspect the brake lines for damage or corrosion. Consult the service manual for detailed diagnostic procedures.

To optimize brake performance, ensure proper alignment of the brake pads and rotors. Use high-quality, OEM-recommended brake pads and rotors designed for your vehicle's weight and performance level. Keep the brake fluid fresh and free from contamination, and avoid mixing different types of brake fluid. Regularly clean and lubricate the caliper slides to ensure smooth operation. For enhanced performance, consider upgrading to high-friction brake pads or cross-drilled rotors, but ensure they are compatible with your vehicle's specifications.
