Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Wear protective gloves and eyewear for safety.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench and lift the caliper away from the rotor.
Inspect the brake pads for uneven wear.
If replacement is necessary:
- Remove old pads and clean the caliper bracket and rotor surface.
- Install new brake pads, ensuring they are oriented correctly.
- Apply brake grease to the backing of the pads to reduce noise.

4. Check and Replace Calipers (if needed)

Inspect calipers for any sticking or malfunction.
If a caliper is found to be faulty:
- Disconnect the brake line and remove the caliper mounting bolts.
- Replace with a new caliper and reconnect the brake line.
- Bleed the brake system to remove any air.

5. Reassemble and Test

Reattach the caliper and ensure it is secured correctly.
Reinstall the wheel and tighten lug nuts to the manufacturer's torque specifications.
Lower the vehicle and perform a test drive to check for proper braking function.
