Here's a general outline of the process. This is not a comprehensive guide and specific steps may vary slightly depending on your exact model and condition. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands (essential for safety!)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric) with extensions and ratchets
* Torque wrench
* Caliper piston compression tool (essential)
* C-clamp (can sometimes be used instead of a caliper piston compression tool, but less ideal)
* Wire brush
* Brake cleaner
* New rear rotors and brake pads
* Safety glasses and gloves
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Jack up the rear of the car and securely support it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts. They are typically on the back of the caliper.
* Use the appropriate socket to loosen and remove the bolts.
* Carefully remove the caliper. It may be attached to the brake line with a flexible hose, so be gentle. You may need to tie it up out of the way with some wire to prevent it from dangling and stressing the brake line.
4. Compress the Caliper Piston: This is crucial. The new pads are thicker than the old ones, and the piston needs to be pushed back into the caliper to accommodate them. Use the caliper piston compression tool (or carefully a c-clamp, but be very careful not to damage the piston or caliper). Push the piston in slowly and evenly. You may need to use the tool several times as you compress the piston. Be careful not to damage the rubber boot around the piston.
5. Remove the Old Brake Pads: The old pads should now slide out easily.
6. Remove the Old Rotors: Some models require removing caliper mounting bracket bolts first (check your repair manual). Then the rotors should slide off the wheel studs. If they're stuck, gently tap them from the back with a rubber mallet.
7. Clean Up: Clean the caliper mounting surfaces, hub, and rotor mounting surfaces with a wire brush and brake cleaner. Remove any rust or debris.
8. Install the New Rotors: Carefully slide the new rotors onto the wheel studs.
9. Install the New Brake Pads: Slide the new brake pads into the caliper.
10. Reinstall the Caliper: Carefully reinstall the caliper onto the mounting brackets. Tighten the bolts to the manufacturer's specified torque.
11. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Final Tightening and Test: After lowering, give the lug nuts one final torque tightening. Then, pump the brake pedal several times to build pressure and check for leaks.
14. Test Drive: Take a short test drive to ensure the brakes are functioning correctly. If you feel anything unusual, immediately stop and have them checked by a mechanic.
Important Notes:
* Consult a Repair Manual: This is crucial. A repair manual specific to your 1997 Oldsmobile Cutlass Supreme will provide detailed instructions, torque specifications, and diagrams.
* Brake Fluid: If you have to completely remove the brake line, you may lose some brake fluid. Be prepared to top off your master cylinder brake fluid reservoir after the repair.
* Safety: Working on brakes is dangerous. If you're unsure about any step, don't hesitate to seek professional help.
This is a general overview. Improper brake repair can lead to serious injury or death. If you have any doubts, please seek professional assistance.
