Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks for added safety.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Caliper tool
Brake cleaner
Wire brush
Safety goggles and gloves

2. Raise the Vehicle

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to raise the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheels.

3. Remove Brake Components

Locate the brake caliper and remove the bolts using a socket wrench.
Carefully slide the caliper off the brake pads and suspend it using a bungee cord or similar to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace

Inspect the old brake pads for wear; if they are below 3mm thick or have uneven wear, replace them.
Measure the rotors with a micrometer; if they are below the manufacturer’s minimum thickness or show signs of scoring or damage, replace them.
Clean the caliper bracket and rotor surface with brake cleaner and a wire brush.

5. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads.
Position the new brake pads in the caliper bracket.
Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use a torque wrench to tighten the lug nuts to the specified torque.
Pump the brake pedal a few times to ensure proper seating of the brake pads.
