Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, micrometer, torque wrench, socket set.
Ensure vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands.

3. Remove Wheels

Use the lug wrench to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe location for reinstallation.

4. Inspect Brake Components

Brake Pads: Remove the caliper bolts using a socket set and slide the caliper off. Inspect the pads for even wear and replace if necessary.
Brake Rotors: Remove the rotor if it shows signs of warping. Clean the mating surface with brake cleaner. If the rotor is warped, either resurface or replace it.
Calipers: Ensure the caliper slides freely and is not stuck. Clean the caliper pins and lubricate them if necessary.

5. Reassemble Components

Reinstall the brake rotor (if replaced).
Slide the brake pads back into place and reattach the caliper.
Torque caliper bolts to manufacturer specifications (usually around 20-30 ft-lbs for Honda).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Lower the Vehicle and Torque Lug Nuts

Carefully lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to manufacturer specifications (typically 80-100 ft-lbs for Honda).
