Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts slightly while the vehicle is still on the ground.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Pads:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor without stressing the brake line.
- Check the brake pads for wear and unevenness.
Replace Pads:
- If uneven wear is found, remove the old brake pads.
- Install new brake pads ensuring they are properly seated in the caliper bracket.
- Apply brake grease to the backing of the pads to prevent noise.

4. Inspect and Replace Rotors (if necessary)

Check the rotors for thickness and surface condition.
If warped or excessively worn, remove the rotor by unbolting it from the hub.
Install new rotors, ensuring they are torqued to manufacturer's specifications.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

6. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Pump the brake pedal a few times to ensure proper pad seating.
Test the brakes at low speed to ensure proper functionality.
