Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect the brake pads for thickness; replace if less than 3mm.
Use a brake pad spreader to compress the caliper piston.
Install new brake pads ensuring they are properly seated.

3. Check and Resurface or Replace Rotors

Measure rotor thickness with a micrometer; if below manufacturer specs, replace or resurface.
If resurfacing, use a brake lathe to achieve a smooth, even surface.
Clean rotor surfaces with brake cleaner before installation.

4. Inspect Calipers

Check for fluid leaks around the calipers; replace if leaking.
Ensure caliper slides are clean and lubricated with high-temperature brake grease.

5. Examine Suspension Components

Inspect struts and shocks for leakage and wear.
Check bushings and ball joints for play; replace any worn components.

6. Tire Inspection

Examine tires for uneven wear; replace if necessary.
Ensure all tires are inflated to the manufacturer’s recommended pressure.
