Tools you'll likely need:
* Jack and jack stands (crucial for safety!)
* Lug wrench
* Wheel chocks
* Socket wrench and sockets (various sizes)
* Brake caliper wrench or C-clamp
* Pliers (for retaining clips)
* Wire brush
* Brake cleaner
* Anti-seize lubricant
* New brake pads
* New rotors (optional, but recommended if grooved or worn excessively)
* Torque wrench (essential for proper tightening)
* Gloves
Procedure:
1. Safety First: Park on a level surface, engage the parking brake firmly, and use wheel chocks on the rear wheels. Raise the front of the car using the jack and securely support it with jack stands. Never work under a car supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper.
* Use the caliper wrench or C-clamp: Carefully compress the caliper piston. You may need to use a C-clamp to push the piston back into the caliper. Be careful not to damage the piston seal or boot. Some pistons turn as they compress; if so, you'll need to turn it as you compress.
* Remove the caliper bolts: Once the piston is compressed sufficiently, remove the caliper bolts and carefully remove the caliper. You might want to hang the caliper using some wire to keep it out of the way and prevent the brake line from stretching or being damaged.
4. Remove the Brake Pads: The old brake pads should now be easily accessible. Remove them. Take note of their orientation; sometimes there's a wear sensor wire attached.
5. Inspect and Replace Rotors (Optional): Inspect the rotors for scoring, grooves, or excessive wear. If necessary, replace them. Use a wire brush to clean the rotor hub mating surface.
6. Install New Brake Pads: Install the new brake pads, ensuring they slide smoothly into their slots.
7. Reinstall the Caliper: Carefully reinstall the caliper over the new brake pads. Make sure the caliper slides freely. Install and tighten the caliper bolts to the manufacturer's specified torque.
8. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts snugly.
9. Lower the Vehicle: Carefully lower the vehicle to the ground.
10. Final Tightening: Torque the lug nuts to the manufacturer's specifications using a torque wrench.
11. Test and Pump Brakes: Lower the vehicle completely. Pump the brake pedal several times to build up pressure. Check for leaks.
12. Test Drive: Take a short test drive to verify that the brakes are working correctly.
Important Considerations:
* Brake Fluid: You might need to bleed the brakes if you opened the brake system (e.g., if you completely removed the caliper from the line and the fluid level dropped significantly). Consult your repair manual on the correct bleeding procedure.
* Wear Sensor: If your old brake pads had a wear sensor wire, you'll likely need to install a new one on the new brake pads.
* Torque Specifications: Always consult your repair manual for the correct torque specifications for the lug nuts and caliper bolts. Over-tightening or under-tightening can lead to damage.
* Parts: Ensure you're using the correct brake pads and rotors for your specific 2000 Saturn SC model.
Again, this is a general guide. Consult a repair manual specific to your vehicle for detailed instructions and safety precautions. If you're unsure about any step, seek professional help. Incorrect brake installation is extremely dangerous.
