Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the brake caliper by loosening the caliper bolts with a wrench.
3. Carefully slide the caliper off the rotor and suspend it (do not let it hang by the brake line).
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads in the caliper bracket, ensuring they are seated correctly.

Tools Required: Socket set, wrench, brake pad spreader.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Use a dial indicator to measure rotor thickness and check for warping.
2. If rotors are warped beyond specifications, replace them; if within limits, resurface them.
3. Clean the rotor surface with brake cleaner.
4. Reinstall the rotor (if resurfaced) or install the new rotor.

Tools Required: Dial indicator, brake cleaner, torque wrench.

4. Check Brake Calipers

Sub-steps:
1. Inspect calipers for signs of leakage or damage.
2. Ensure caliper pistons move freely; clean and lubricate as necessary.
3. Replace calipers if they are sticking or damaged.

Tools Required: Wrench set, brake fluid, grease.

5. Reinstall Components

Sub-steps:
1. Reattach the brake caliper over the new pads and rotor.
2. Tighten caliper bolts to manufacturer specifications using a torque wrench.
3. Reinstall the wheel and hand-tighten the lug nuts.

Tools Required: Torque wrench.

6. Final Checks

Sub-steps:
1. Lower the vehicle and torque the lug nuts to specifications.
2. Pump the brake pedal a few times to seat the brake pads.
3. Test the brakes at low speed to ensure proper function.
