Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel to access the brake components.
2. Use a socket set to remove the caliper bolts and carefully lift the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads by aligning them in the caliper bracket.
5. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

3. Check and Resurface/Replace Brake Rotors

Sub-steps:
1. If the rotors are warped, use a dial indicator to measure runout; if above specifications, they need resurfacing or replacement.
2. If resurfacing, mount the rotor on a brake lathe and follow the lathe instructions.
3. If replacing, remove the old rotors by unscrewing the retaining screws (if applicable) and sliding them off the hub.
4. Install new rotors and secure them with retaining screws if applicable.

4. Brake Fluid Maintenance

Sub-steps:
1. Check the brake fluid level in the reservoir; if low, top off with the manufacturer-recommended brake fluid type.
2. If the fluid is contaminated, perform a brake fluid flush by removing the old fluid from the reservoir and bleeding each brake line until clean fluid emerges.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
2. Reconnect the battery.
3. Pump the brake pedal a few times to ensure proper braking pressure before driving.
