Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Using a caliper tool, retract the caliper piston.
Remove the caliper bolts with a socket set and lift the caliper off the rotor.
Inspect the brake pads for thickness, replacing if less than 3mm.
Install new brake pads, ensuring they are seated correctly.

3. Check and Resurface/Replace Brake Rotors

Inspect the brake rotors for warping; use a run-out gauge to measure.
If warped, resurface the rotors or replace if beyond specifications (usually more than 0.5mm of warping).
Clean the rotor surface with brake cleaner before reinstallation.

4. Inspect and Repair Suspension Components

Check control arms, tie rods, and bushings for wear or damage.
Replace any worn suspension parts to ensure proper alignment and handling.

5. Wheel Alignment and Balancing

After repairs, have the vehicle's wheels aligned and balanced to prevent uneven tire wear and vibration during braking.
