Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a lug wrench to loosen the lug nuts.
- Jack up the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Visually inspect brake pads for uneven wear and thickness.
- Measure rotor thickness and check for warping using a dial indicator.
- If rotors are warped or pads are unevenly worn, proceed to replace them.
Replace Brake Rotors:
- Remove the caliper bolts using a socket set and hang the caliper using a bungee cord (do not let it hang by the brake line).
- Remove the old rotor and install the new rotor, ensuring it is properly seated.
- Reattach the caliper and torque the bolts to manufacturer specifications (usually around 25-30 Nm).
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.
- Use brake grease on the backing plates of the pads to prevent noise.
Reassemble Wheel:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 120 Nm).

3. Suspension Inspection and Repair

If suspension components are found to be worn or damaged, replace them as needed.
Ensure all bolts are torqued to manufacturer specifications.
