Diagnostic Steps

1
Inspect brake pads and rotors for uneven wear or damage.
2
Check brake rotor thickness and runout using a dial indicator.
3
Examine suspension components (e.g., control arms, tie rods) for wear or damage.
4

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Loosen wheel lug nuts slightly while the vehicle is on the ground.

2. Raise Vehicle

Use a jack to lift the front of the vehicle.
Secure it with jack stands for safety.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check the pads for uneven wear; replace if necessary.
- Remove the brake caliper bolts using a socket wrench.
- Lift the caliper off the rotor and secure it with a bungee cord.
- Measure rotor thickness and check for warping using a micrometer and dial indicator.
Replace Rotors (if warped or below minimum thickness):
- Remove the old rotor and clean the hub surface.
- Install the new rotor, ensuring it is flush against the hub.
Replace Brake Pads (if worn):
- Remove old pads and install new pads in the caliper bracket.
- Ensure anti-rattle clips are properly attached.

4. Reassemble and Torque

Reattach the brake caliper over the new pads.
Tighten caliper bolts to the manufacturer’s specified torque (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

5. Lower Vehicle and Final Checks

Remove the jack stands and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications (typically around 75-85 ft-lbs).
Pump the brake pedal several times to seat the brake pads against the rotor before driving.
