Diagnostic Steps

1

2
Check brake pads for thickness and condition.
3
Examine suspension components (e.g., control arms, ball joints) for wear.
4
Test wheel alignment and balance.
5

Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Remove the wheel using a socket set.
Remove caliper bolts and carefully lift the caliper off the rotor. Support it so it doesn't hang from the brake line.
Remove the rotor from the hub by unscrewing any retaining screws or pulling it off.
Inspect the rotor for warping using a dial gauge or a straight edge. Replace if warped beyond specifications (usually more than 0.005 inches).
Install new rotors, ensuring they are clean from any oil or debris. Use brake cleaner if necessary.

3. Inspect and Replace Brake Pads

Check the brake pads for wear. If they are below the minimum thickness (typically 3mm), replace them.
Remove the old pads from the caliper bracket.
Apply brake paste to the back of the new pads to prevent squealing.
Install the new pads into the caliper bracket.

4. Reassemble and Test

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and torque the lug nuts in a star pattern to the specified value (typically 80-100 ft-lbs).
Repeat the process on the other side if necessary.
