2000 Cadillac Eldorado Brake Service (ONLINE REPAIR MANUALS)

Replacement

• Raise and support vehicle.
• Mark relationship of wheel to axle flange, then remove wheel and tire assembly.
• Remove brake hose from caliper, Fig. . Plug openings in caliper and brake hose to prevent fluid loss and contamination.
• Lift up on end of cable spring to free end of cable from lever, then disconnect parking brake cable from lever.
• Remove bolt and washer attaching cable support bracket to caliper body assembly.
• Remove sleeve bolt and caliper body assembly.
• Reverse procedure to install, then bleed brakes.

Disassemble

• Remove caliper from vehicle as outlined under "Caliper S... "

Replacement

• Remove approximately ^2/3 of brake fluid from master cylinder.
• Raise and support front of vehicle, then remove wheel and tire assembly.
• Push piston back into caliper bore using suitable C-clamp, Fig. .
• If caliper assembly is being removed for service, remove inlet fitting attaching bolt, copper washer, and inlet fitting from caliper housing. Plug opening in inlet fitting to prevent fluid loss and contamination. Do not crimp brake hose since this may damage hose's internal structure. If only shoe and lining assemblies are to be replaced, do not disconnect brake line fittin...

• Grease or any other foreign material must be kept off brake linings, caliper, surfaces of disc and external surfaces of hub during service procedures.
• Handling brake disc and caliper should be done in a way to avoid deformation of disc and nicking or scratching brake linings.
• If inspection reveals rubber piston seals are worn or damaged, they should be replaced.
• During removal and installation of a wheel assembly, ensure not to interfere with or da...

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.

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, initial brake pedal mo...

The caliper assembly, Fig. , has a single bore and is mounted to the support bracket with two mounting bolt and sleeve assemblies. Hydraulic pressure created by applying the brake pedal is converted by the caliper to a stopping force. This force acts equally against the piston and the bottom of the piston bore to move the piston outward and to slide the caliper inward resulting in a clamping action. This clamping action presses the linings against the rotor, creating friction to stop the vehicle.

When the parking brake is applied, the external caliper parking brake lever moves and ro...
