Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

Tools Required:

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

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the bolts securing it.
Carefully slide the caliper off the brake rotor.
Use a C-clamp to compress the caliper piston back into the caliper housing if replacing pads.
Remove the old brake pads from the caliper bracket and inspect for wear.
Install new brake pads, ensuring they are seated properly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring; if damaged, replace.
Remove the caliper bracket by unscrewing its mounting bolts.
Slide the rotor off the hub. Clean the hub surface before installing a new rotor.
Install the new rotor, ensuring it is seated correctly.

5. Reassemble Components

Reattach the caliper bracket and torque the bolts to manufacturer specifications.
Slide the caliper back over the new pads and secure it with its bolts.
Reinstall the wheel, hand-tightening the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and tighten the lug nuts in a star pattern to the specified torque.
Reconnect the battery.
Pump the brake pedal a few times to ensure proper engagement of the brake pads.
