Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

1.1 Remove the wheel using a socket set.
1.2 Unbolt the brake caliper and hang it using a wire to avoid strain on the brake line.
1.3 Remove the old brake pads from the caliper bracket.
1.4 Install new brake pads, ensuring they are seated properly.
1.5 Reattach the brake caliper and torque bolts to manufacturer's specifications.

3. Inspect and Resurface/Replace Rotors

3.1 Check the rotor surface for grooves or warps using a straightedge.
3.2 If warped, either resurface the rotors or replace them if below minimum thickness.
3.3 Clean the rotor surface with brake cleaner before installation.
3.4 Reinstall rotors and torque them to specified values.

4. Check and Repair Suspension Components

4.1 Inspect suspension bushings, control arms, and struts for wear.
4.2 Replace any worn components as necessary.
4.3 If needed, perform a wheel alignment following repairs.

5. Tire Inspection and Balancing

5.1 Inspect tires for uneven wear or damage.
5.2 Balance tires if necessary, using a tire balancing machine.
5.3 Rotate tires if uneven wear is found to promote even wear.
