Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather all necessary tools and parts.
Wear safety gloves and goggles.

2. Raise Vehicle

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

3. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping using a dial indicator.
- If warped beyond specifications (usually 0.002 inches), proceed to replace.
Remove Caliper: Unbolt the brake caliper and hang it securely using a bungee cord or similar method.
Remove Rotor: Unscrew any retaining screws and slide the rotor off the hub.
Install New Rotor: Clean the hub surface, then install the new rotor and secure it with retaining screws.

4. Inspect and Replace Brake Pads

Check Pads: Measure the thickness of the pads; replace if less than 3mm.
Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Apply brake grease to the backing of the new pads and install them in the caliper bracket.

5. Reassemble and Lower Vehicle

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

6. Test Brake System

Pump the brake pedal a few times to seat the pads.
Perform a test drive to ensure the issue is resolved.
