Here's a general overview of the process. Specific steps and tools may vary slightly depending on the exact Seville model and brake configuration (drum or disc). Always consult a repair manual specific to your 1994 Cadillac Seville for detailed instructions and diagrams.
Tools You'll Likely Need:
* Jack and jack stands (essential for safety)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Torque wrench
* Brake caliper piston compressor tool (if replacing disc brakes)
* C-clamp (possibly, for compressing caliper pistons)
* Wire brush
* Brake cleaner
* New brake pads or shoes (and hardware if necessary)
* New brake rotors (if necessary for disc brakes)
* New brake drums (if necessary for drum brakes)
* Penetrating oil (like PB Blaster)
General Steps (assuming rear disc brakes, which are more common on later-model Sevilles):
1. Safety First: Park the vehicle on a level surface, engage the parking brake, and use wheel chocks on the front wheels. Raise the rear of the vehicle using the jack and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper: Depending on the specific design, you may need to:
* Unbolt the caliper from its mounting bracket. Penetrating oil might be needed to loosen stubborn bolts.
* Support the caliper with wire or a bungee cord to prevent it from hanging by the brake line.
4. Compress the Caliper Piston(s): Using the caliper piston compressor tool, carefully compress the piston(s) back into the caliper. This creates space for the new, thicker brake pads. If you don't have a specialized tool, a C-clamp can sometimes work, but be very careful not to damage the piston or seals.
5. Remove the Old Pads: Once the piston is compressed, remove the old brake pads. Inspect the condition of the caliper slides – they should move freely. Clean them with a wire brush and lubricate with brake caliper grease.
6. Inspect the Rotor: Inspect the rotor for wear, scoring, or excessive rust. If the rotor is damaged, it needs to be replaced.
7. Install the New Pads: Install the new brake pads, making sure they're seated correctly.
8. Reinstall the Caliper: Reinstall the caliper onto its mounting bracket, ensuring the caliper bolts are properly tightened to the manufacturer's specifications (use your torque wrench).
9. Reinstall the Wheel: Reinstall the wheel and tighten the lug nuts to the proper torque specification.
10. Lower the Vehicle: Carefully lower the vehicle to the ground.
11. Pump the Brakes: Before driving, pump the brake pedal several times to ensure the brakes are functioning correctly.
If your 1994 Cadillac Seville has rear drum brakes: The procedure is significantly different and involves removing the brake drum, adjusting the self-adjusters, replacing the brake shoes and springs, and potentially replacing the wheel cylinders. This is even more complex and requires specific tools and expertise.
Crucial Considerations:
* Bleeding the Brakes: After a brake job, it's often necessary to bleed the brakes to remove air from the brake lines. This requires a helper and a bleeding wrench. Failure to bleed the brakes properly can result in spongy brakes or brake failure.
* Torque Specifications: Always refer to your repair manual for the correct torque specifications for all bolts and nuts. Over-tightening can damage components.
* Brake Fluid: Brake fluid is corrosive and hygroscopic (absorbs moisture). Avoid getting it on painted surfaces. If you spill any, clean it up immediately. If you need to add brake fluid, use the correct type specified for your vehicle.
Again, this is a simplified overview. Consult a repair manual specific to your vehicle before attempting this repair. If you're not comfortable with this level of mechanical work, it's best to have a qualified mechanic perform the brake service. Your safety and the safety of others depend on properly functioning brakes.
