Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove lug nuts with a socket and take off the wheel.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if they are below manufacturer's specifications (typically 3mm).
- Measure the rotor thickness and check for warping using a dial gauge; replace if warped beyond specifications.
- If rotors are not within spec, proceed to replace them.
Replace Brake Pads and Rotors
- Remove caliper bolts and gently lift the caliper out of the way.
- Remove old pads and install new pads, ensuring proper fit and orientation.
- If replacing rotors, remove the old rotor and install the new rotor, ensuring it is properly seated.
Reassemble Components
- Reattach the brake caliper and tighten bolts to manufacturer's torque specifications (usually between 25-35 ft-lbs).
- Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.

3. Suspension Inspection

Check Suspension Components
- Inspect tie rods, ball joints, and control arms for any signs of wear or play.
- Replace any damaged components to ensure proper handling and braking.

4. Final Checks

Reconnect the battery.
Perform a brake fluid check and top off if necessary.
