Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and use a socket wrench to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Compare new brake pads to old ones to ensure correct size.

Installation of New Brake Pads:

Apply brake grease to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket.
Reposition the caliper over the new pads and secure it using the mounting bolts, tightening to manufacturer specifications (usually around 25-35 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are worn or damaged, remove them by unscrewing any retaining screws and sliding them off the wheel hub.
Install new rotors in reverse order, ensuring they are seated properly.

5. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 110-120 Nm).

6. Final Checks

Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and add fluid if necessary.
