Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves during the procedure.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake rotors for any signs of warping or uneven wear. Use a run-out gauge if necessary.
4. If rotors are warped, remove the caliper and bracket, then unscrew the rotor from the hub.
5. Install new brake rotors, ensuring they are properly torqued to manufacturer specifications (typically 80-100 ft-lbs).

Tools Required:

Jack and jack stands
Socket set
Torque wrench

3. Replace Brake Pads

Sub-steps:
1. Using the socket set, remove the caliper bolts and slide the caliper off the rotor.
2. Remove old brake pads from the caliper bracket.
3. Install new brake pads in the bracket, ensuring they are properly aligned.
4. Reattach the caliper over the new pads and secure with bolts, torquing to specifications.

Tools Required:

Brake pad spreader tool (optional)
Socket set
Torque wrench

4. Check Wheel Bearings

Sub-steps:
1. With the wheel off, check for play in the wheel bearings by shaking the hub.
2. If there is excessive play, remove the hub assembly and inspect the bearings.
3. Replace any worn or damaged bearings and reassemble, torquing to specifications.

Tools Required:

Socket set
Torque wrench

5. Verify Tire Balance and Condition

Sub-steps:
1. Inspect tires for uneven wear, bulges, or damage.
2. Take the vehicle to a tire shop for balancing if necessary.
3. Rotate tires if uneven wearing is observed.
