Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, and engage the parking brake.
Wear safety glasses and gloves.

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: Use a run-out gauge to measure rotor warping.
Replace (if warped):
1. Remove the caliper bolts using a socket set.
2. Detach the caliper and suspend it using a bungee cord to avoid straining the brake line.
3. Remove the rotor by loosening the retaining screws (if present) and pulling it off the hub.
4. Clean the hub surface thoroughly before installing the new rotor.
5. Install the new rotor in the reverse order.

4. Inspect and Replace Brake Pads

Inspect: Check the thickness and wear patterns of the brake pads.
Replace (if uneven or worn):
1. Remove the caliper bracket bolts and take off the caliper.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads in the bracket.
4. Reinstall the caliper over the new pads and tighten the bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value.

6. Test Brake System

Pump the brake pedal to ensure proper engagement of the pads against the rotors.
Check for leaks around the calipers and ensure smooth operation.
