Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to raise the front end of the vehicle.
Secure with jack stands for safety.

3. Remove the Wheels

Use a lug wrench to remove the lug nuts from the front wheels.
Take off the wheels to access the brake components.

4. Inspect and Replace Brake Rotors

Check the rotors for warping; if warped, replace them.
- Tools Required: Torque wrench, brake rotor puller (if necessary).
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws and pulling it off.
- Install the new rotor and secure it with retaining screws.
- Torque Value: 70-90 lb-ft for rotor retaining screws.

5. Inspect and Replace Brake Pads

Inspect the brake pads for wear; replace if they are below the manufacturer’s recommended thickness.
- Slide the old pads out of the caliper bracket.
- Install new brake pads ensuring they are properly seated.
- Reattach the caliper over the new pads.
- Torque Value: 20-30 lb-ft for caliper bolts.

6. Reassemble and Lower the Vehicle

Reinstall wheels and tighten lug nuts in a criss-cross pattern.
Lower the vehicle and remove jack stands.

7. Test Brake System

Pump the brake pedal several times to ensure proper engagement.
Perform a test drive to confirm the issue has been resolved.
