Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, measuring calipers, torque wrench.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts slightly on the wheels where brake pads will be replaced.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheels.

3. Remove Brake Caliper

Using the socket set, remove the bolts securing the brake caliper to the bracket.
Carefully slide the caliper off the rotor. Do not let the caliper hang by the brake line; use a bungee cord or similar support.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the old pads with the new ones to ensure proper fit.
Insert the new brake pads into the bracket.

5. Reassemble Components

Compress the brake caliper piston using a caliper tool or a C-clamp until it’s fully retracted.
Reattach the caliper over the new brake pads and secure it with the bolts.
Tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-35 Nm).

6. Reinstall Wheels

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then tighten the lug nuts in a crisscross pattern to the recommended torque (usually around 100-120 Nm).

7. Test the Brakes

Before driving, pump the brake pedal several times to seat the brake pads.
Ensure everything is functioning properly before taking the vehicle on the road.
