Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Use a dial indicator to check for warping. Replace if warp exceeds manufacturer's specifications.
Replace Brake Pads:
- Remove caliper bolts with a socket.
- Lift the caliper off the rotor and support it with a bungee cord.
- Remove the old brake pads and install new ones, ensuring they are properly seated.

4. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs for the Accord).

5. Test Brakes

Reconnect the battery.
Start the vehicle and pump the brakes to ensure proper pad seating.
Conduct a test drive to verify the repair, checking for any vibrations during braking.
