Diagnostic Steps

1
Inspect brake pads for wear and proper installation.
2
Check brake rotors for warping or uneven wear using a dial indicator.
3
Examine suspension components (tie rods, bushings) for wear or damage.
4
Check wheel alignment and tire balance.
5

Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; replace if they are below the manufacturer's minimum thickness.
Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Measure rotor thickness with a micrometer; if below specifications, replace.
If rotors are within spec but warped, use a brake lathe to resurface them.
Clean the rotor surface with brake cleaner and install back onto the hub.

5. Reassemble and Test

Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern.
Lower the vehicle back to the ground and reconnect the negative battery terminal.
