Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles to protect yourself.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen lug nuts with the vehicle on the ground.
Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Remove the caliper by unbolting it from the bracket.
Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if they are below the minimum thickness, replace them.
Apply brake grease to the back of the new pads to prevent squealing.
Install the new brake pads firmly into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if needed), torque wrench.
Check the brake rotor for grooves or warping; replace if damaged.
If replacing, remove the rotor by unbolting it from the hub.
Clean the hub surface before installing the new rotor.
Install the new rotor and torque the bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reposition the caliper over the new pads and securely bolt it back to the bracket.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal a few times to seat the pads properly.
