Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks for additional safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Remove Wheels

Use a socket set to remove lug nuts and take off the wheels, exposing the brake assembly.

4. Inspect and Replace Brake Pads

Inspect: Check the brake pads for uneven wear; if they are worn unevenly, replace them.
Replace:
- Remove the caliper mounting bolts using a socket.
- Slide the caliper off the brake rotor and support it to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the same orientation as the old ones.
- Use a C-clamp to compress the caliper piston back into its housing.

5. Reassemble Components

Reattach the caliper over the new brake pads and tighten the caliper mounting bolts to the manufacturer’s specified torque settings.
Replace the wheel and hand-tighten the lug nuts.

6. Repeat for Other Wheels

Follow the same procedure for the other wheels, inspecting each brake assembly.

7. Test Brake System

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Start the vehicle and pump the brake pedal several times to seat the pads properly.
Test drive the vehicle at low speeds to ensure proper brake function.
