Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake caliper tool, brake cleaner.
Remove the wheel to access the brake components.
Inspect the brake pads for thickness; if below minimum thickness, replace them.
Remove the caliper bolts and carefully slide the caliper off the rotor.
Replace the brake pads and reassemble the caliper.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, dial indicator, socket set.
If rotors are warped (check with a dial indicator), remove the caliper and rotor.
Use a torque wrench to ensure proper installation of new rotors.
Reinstall the caliper and ensure that all bolts are torqued to manufacturer specifications.

4. Suspension and Wheel Inspection

Tools Required: Jack and jack stands, torque wrench.
Lift the vehicle and inspect suspension components for any visible damage or wear.
Check wheel bearings by moving the wheel side to side; replace if there is play.
Reinstall the wheel and torque lug nuts to the appropriate specification.
