Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift Vehicle

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

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Measure rotor thickness with a micrometer; if below minimum specification, replace.
- Check for signs of warping using a runout gauge.
Replace Rotors:
- Remove caliper bolts with a socket set and carefully hang the caliper using a bungee cord.
- Remove the old rotor.
- Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
- Install the new rotor and reattach the caliper, tightening the bolts to manufacturer's torque specifications (usually around 100 Nm).

4. Inspect and Replace Brake Pads

Check brake pads for wear; if less than 3 mm, replace.
Remove the caliper bracket if necessary, and slide out the old pads.
Apply brake grease to the back of the new pads to prevent squeaking.
Install new pads and reassemble the caliper.

5. Check Suspension and Wheel Bearings

Inspect suspension components (control arms, bushings, etc.) for any signs of damage or looseness.
Check wheel bearings for play by rocking the wheel; replace if necessary.

6. Perform Wheel Alignment

Utilize a wheel alignment tool to check and adjust alignment settings to manufacturer's specifications.

Tools Required:

Hydraulic jack
Jack stands
Socket set
Micrometer
Runout gauge
Wheel alignment tool
Torque wrench
Brake grease

Parts Required:

Brake rotors
Brake pads
Wheel bearings (if needed)

Estimated Repair Time: 3-5 hours

Safety Warnings:
