Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working on the braking system.

2. Remove Wheel

Loosen lug nuts using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
Inspect the brake pads for uneven wear; if the pads are uneven, replace them.
Use a C-clamp to compress the caliper piston back into the caliper housing.
Install new brake pads, ensuring they are seated correctly in the caliper bracket.

4. Check Brake Rotors

Inspect the rotors for any signs of warping or excessive wear.
If the rotors are damaged, they should be resurfaced or replaced as necessary.
Clean the rotor surface with brake cleaner to remove any debris or oil.

5. Reassemble Components

Reattach the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.

6. Final Check

Reconnect the battery.
Pump the brake pedal several times to ensure the brake pads are seated properly.
Test drive the vehicle at low speeds to ensure brakes function correctly.
