Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
C-clamp (for caliper retraction)
Brake pads (as needed)
Brake rotors (if replacement is necessary)
Brake lubricant

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly without removing them.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the bolts securing it to the bracket using the socket set.
Carefully lift the caliper away from the rotor and secure it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Compare new brake pads with old ones to ensure correct size.
Install the new brake pads, applying brake lubricant to the backing of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor surface for any significant scoring or warping.
If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, ensuring it is seated properly and secured.

5. Reassemble Braking Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts in a crisscross pattern to ensure even pressure.
Pump the brake pedal a few times to seat the brake pads properly against the rotor.
