Solution

1. Preparation

Gather tools and parts needed for the brake pad replacement.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Old Brake Pads

Locate the brake caliper and inspect the caliper mounting bolts.
Use a socket wrench to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor without straining the brake line.
Remove the old brake pads from the caliper bracket.

4. Inspect and Clean

Inspect the brake rotor for any scoring or uneven wear; resurface or replace if necessary.
Clean the caliper and bracket area using brake cleaner to remove dust and debris.

5. Install New Brake Pads

Place the new brake pads into the caliper bracket, ensuring they are seated properly.
Reinsert the caliper over the new pads and align it with the rotor.
Reattach and tighten the caliper mounting bolts to the manufacturer’s specified torque settings (usually around 20-25 ft-lbs, check manufacturer specifications).

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Reconnect the battery and pump the brake pedal several times to ensure the brake pads are seated properly.
