Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow the vehicle to cool.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Use a dial indicator to check for warping.
- If warped beyond specifications (typically 0.002 inches), replace rotors.
Replace Brake Pads:
- Remove caliper bolts and slide the caliper off the rotor.
- Replace brake pads, ensuring proper orientation and alignment.
Check Calipers:
- Ensure calipers move freely on their slides; clean and lubricate if necessary.

4. Reassemble and Lower Vehicle

Reinstall the brake caliper over the new pads and tighten caliper bolts to manufacturer torque specifications (usually 20-30 ft-lbs).
Reattach the front wheels and lower the vehicle to the ground.

5. Test Drive

Conduct a test drive to ensure proper braking function and check for vibrations.
