Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Loosen the lug nuts of the front wheels slightly before lifting the vehicle.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the front wheels to access the brake assembly.
4. Inspect the brake rotors for warping using a dial indicator. If warped beyond manufacturer specifications, proceed with replacement.
5. Remove the caliper by unscrewing the caliper bolts and securing it to the suspension (do not let it hang on the brake line).
6. Remove the rotor by taking off the retaining screws (if present) and sliding the rotor off the hub.
7. Clean the hub surface with a wire brush to ensure a proper seat for the new rotor.
8. Install the new rotor, ensuring it sits flush against the hub. Reinstall any retaining screws.

3. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake caliper tool to make room for the new pads.
3. Install the new brake pads into the caliper bracket.
4. Reattach the caliper over the new pads and secure with the caliper bolts.

4. Reinstall Wheels and Lower Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80 ft-lbs).

5. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Pump the brake pedal a few times to ensure proper brake pressure before driving.
