Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the vehicle's 12V battery for safety.

2. Inspect Brake Pads

Remove the wheel to access the brake assembly.
Check the brake pads for thickness; replace if less than 3mm.
Ensure pads are not unevenly worn. If they are, replace both pads on the axle.

3. Check Brake Rotors

Use a micrometer to measure rotor thickness; compare against manufacturer specifications.
Inspect for warping using a dial indicator. If warped, resurface or replace rotors as needed.
Clean the rotor surface with brake cleaner and a lint-free cloth.

4. Examine Brake Calipers

Inspect calipers for any signs of leakage or sticking.
Ensure the caliper slides freely by pushing it against the mounting bracket; if it sticks, clean and lubricate the slides.
Replace calipers if they are damaged or not functioning properly.

5. Wheel Alignment and Balance

Check the alignment of the wheels; adjust as per manufacturer specifications.
Inspect the wheel balance; re-balance wheels if necessary.
