Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, micrometer.
Remove the wheel using a socket wrench.
Unbolt the brake caliper and secure it with a bungee cord to avoid strain on the brake line.
Remove the brake rotor and inspect for warping using a micrometer; if warped beyond specifications, replace it.
Clean the new rotor with brake cleaner before installation.
Reinstall the rotor and torque the lug nuts to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket and inspect their thickness.
If the pads are worn down, replace them with new pads, ensuring they match the specifications for your Honda Accord.
Apply brake grease on the backing of the new pads to prevent squeaking.
Reattach the caliper over the new pads and torque bolts to specifications.

4. Check Suspension and Wheel Bearings

Tools Required: Jack, jack stands, socket set.
Lift the front of the vehicle using a jack and support it with jack stands.
Inspect the suspension components for any signs of wear or damage (e.g., control arms, bushings).
Check the wheel bearings by trying to wiggle the wheel; if there is excessive play, they may need to be replaced.

5. Tire Balancing and Alignment

Take the vehicle to a tire shop for balancing and alignment if necessary.
Ensure all tires are properly inflated and in good condition.
