Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner.
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during inspection.

2. Inspect Brake Pads and Rotors

Sub-steps:
1. Use the lug wrench to loosen wheel lug nuts, then lift the vehicle with the jack and secure it with jack stands.
2. Remove the wheels to access the brake assembly.
3. Visually inspect the brake pads for thickness; replace if less than 3mm.
4. Use a micrometer to measure rotor thickness and check for warping using a dial indicator.
5. Clean the rotors and brake components with brake cleaner.

3. Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the caliper bolts and carefully slide the caliper off the rotor.
2. Replace old pads with new ones, ensuring they fit snugly in the caliper.
3. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).

4. Resurface or Replace Rotors (if necessary)

Sub-steps:
1. If rotors are warped, either resurface them or replace them with new ones.
2. Install the new or resurfaced rotors, ensuring they are clean and free from grease.
3. Torque the rotor retaining nuts to manufacturer specifications.

5. Check Suspension and Alignment

Sub-steps:
1. Inspect suspension components (tie rods, control arms, bushings) for any signs of wear or damage.
2. If any issues are found, replace the affected components.
3. Perform a wheel alignment to ensure proper tracking.
