Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

Tools Required:

Jack and jack stands
Lug wrench
Brake caliper tool or C-clamp
Torque wrench
Socket set
Brake cleaner
Safety glasses and gloves

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and securely place jack stands under the chassis.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually 2 bolts).
Use the appropriate socket to remove the caliper bolts.
Carefully slide the caliper off the rotor and support it using a bungee cord or hang it to avoid stressing the brake line.

4. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake caliper tool or C-clamp to compress the caliper piston back into the housing.
Install the new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reinstall the Brake Caliper

Position the caliper over the new brake pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer specified torque (typically around 30 Nm).

6. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts to secure the wheel in place.
Lower the vehicle from the jack stands and onto the ground.
Tighten the lug nuts in a star pattern to the manufacturer specified torque (typically around 120 Nm).

7. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure the brake pads are seated properly against the rotor.
Check brake fluid level again and top off if necessary.
