Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for wear and ensure they are not excessively worn or damaged.

Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, dial indicator, caliper gauge, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench to access the brake components.

3. Inspect and Replace Brake Rotors

Use a dial indicator to measure rotor runout; if it exceeds manufacturer specifications, replace the rotors.
If necessary, remove the caliper by unbolting it from the bracket and hanging it to avoid strain on the brake line.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free of any grease.

4. Inspect and Replace Brake Pads

Inspect brake pads for wear; if they are below the minimum thickness, replace them.
Remove the old pads from the caliper bracket and install new pads, applying brake grease to the backing as needed.

5. Reassemble and Torque

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque value.
Reinstall the wheels and hand-tighten the lug nuts.

6. Lower Vehicle and Conduct Final Checks

Carefully lower the vehicle off the jack stands.
Tighten the lug nuts to the specified torque in a crisscross pattern.
Perform a brake fluid check and top up if necessary.
