Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.
Put on safety goggles and gloves to protect yourself during the process.

2. Lift the Vehicle

Use a lug wrench to loosen the lug nuts of the wheel where the brakes will be inspected or replaced.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Remove the Brake Caliper

Locate the caliper bolts (usually two) at the back of the brake caliper.
Use a socket set to remove the caliper bolts and gently slide the caliper off the brake rotor.
Support the caliper using a bungee cord or similar to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage or leaks.
If replacing, install new pads in the caliper bracket, ensuring they are aligned correctly.
Apply brake grease to the backing plates of the new pads to reduce noise.

5. Reinstall the Brake Caliper

Slide the caliper back over the new brake pads.
Reinstall and torque the caliper bolts to the manufacturer's specifications (typically around 25-35 Nm).
Ensure the caliper moves freely and does not bind.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).
Pump the brake pedal a few times to ensure proper pad seating before driving.
