Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear appropriate safety gear such as gloves and goggles.

2. Inspect and Remove Brake Components

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Lift the vehicle using a jack and secure with jack stands.
Remove the wheel using the lug wrench.
Inspect the brake rotors for warping by measuring the thickness at several points using a micrometer.

3. Replace or Resurface Brake Rotors

If rotors are warped beyond the manufacturer’s specifications, replace or resurface them.
Sub-steps:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and support it using a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- If resurfacing, follow the shop specifications for machining.

4. Inspect and Replace Brake Pads

Inspect the brake pads for thickness and uneven wear.
Sub-steps:
- Remove the old pads from the caliper bracket.
- Clean the caliper bracket and apply anti-squeal lubricant to the contact points.
- Install new brake pads ensuring they are seated properly.

5. Reassemble and Torque Components

Reinstall the rotor and caliper.
Sub-steps:
- Reattach the caliper and tighten caliper bolts to manufacturer specifications (check service manual for torque values).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value in a star pattern.

6. Test Drive

Conduct a test drive to ensure the repair was successful and monitor for vibrations.
