Diagnostic Steps

1
Inspect brake rotors for warping or damage using a dial indicator.
2
Check brake pad thickness and condition for uneven wear.
3
Examine wheel alignment and balance using alignment equipment.
4
Inspect suspension components for wear or damage (e.g., control arms, bushings).
5
Check tire condition and pressure for any irregularities.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely jack up the front of the vehicle.
Use jack stands for safety.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Remove the wheel from the hub.

3. Inspect and Replace Brake Rotors

Check for Warping: Use a dial indicator to measure rotor runout. If warped, proceed with replacement.
Remove Caliper: Unbolt the brake caliper using the appropriate socket. Suspend the caliper with a wire to avoid stress on the brake line.
Remove Brake Rotor: If necessary, remove the retaining screws and slide off the rotor. Clean the hub surface with a wire brush.
Install New Rotor: Place the new rotor on the hub, ensuring it is seated properly.

4. Inspect and Replace Brake Pads

Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Apply brake grease to the backing of the new pads and install them into the caliper bracket.

5. Reassemble Components

Reposition the brake caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the specified value.

6. Wheel Alignment Check

If misalignment is suspected, have a professional conduct a wheel alignment.
