Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
- Check the brake pads for thickness; replace if worn down to less than 1/4 inch.
Replacement:
- If necessary, remove the old brake pads by sliding them out of the caliper bracket.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

5. Check and Replace Brake Rotors (if needed)

Inspect the rotors for grooves or damage. If they are scored or too thin, replace them.
Remove the caliper bracket bolts to take off the bracket and rotor.
Replace the rotor by sliding the new rotor onto the hub and securing it with the bolts.

6. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer torque specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer specifications (typically 80-100 ft-lbs).

7. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
