Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as necessary.
Secure with jack stands to ensure stability during work.

3. Remove Wheel

Use a socket set to loosen the lug nuts and remove the wheel.
Place the wheel aside in a safe location.

4. Inspect Brake Components

Brake Rotors:
- Visually inspect the rotors for warping or scoring.
- Use a dial indicator to measure rotor runout; replace if out of specification (typically over 0.002 inches).
Brake Pads:
- Check pad thickness; replace if below manufacturer's minimum specification (usually 3mm).
Suspension Components:
- Inspect control arms, bushings, and struts for wear.
- Replace any damaged components.

5. Replace Brake Rotors and Pads

Rotors:
- Remove the caliper and bracket (use appropriate torque values for reassembly).
- Slide off the old rotor and install the new rotor.
Brake Pads:
- Compress the caliper piston using a brake tool.
- Install new brake pads ensuring proper orientation.

6. Reassemble and Lower Vehicle

Reattach caliper and bracket, tightening to specified torque values.
Replace the wheel and tighten lug nuts in a crisscross pattern.
Lower the vehicle back to the ground.

7. Test Brake Function

Pump the brakes a few times to seat the pads properly.
Check for any unusual noises or issues during a test drive.
