2
Check brake rotors for warping using a runout gauge.
3
Examine suspension components (control arms, bushings, etc.) for wear or damage.
4

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts slightly before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads

Remove caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
Remove old brake pads and inspect for uneven wear; replace if necessary.
Install new brake pads ensuring they are properly seated in the caliper bracket.

Brake Rotors

Check rotor surface for scoring or warping using a micrometer.
If rotors are warped (exceeding manufacturer specifications), remove them by unscrewing the retaining screws (if applicable) and pulling them off the hub.
Install new rotors, ensuring they are clean and free of grease; torque bolts to manufacturer specifications.

4. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.

5. Final Checks

Check brake fluid level and top off if necessary.
Test the brake system by pressing the brake pedal a few times to seat the pads.
