Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition for any signs of wear or damage.
3
Examine suspension components (such as control arms and bushings) for wear or damage.
4

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench
Lift the vehicle using a jack and secure it on jack stands. Remove the front wheels using a lug wrench.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts and hang it using a bungee cord to avoid straining the brake line.
2. Remove the brake pads by sliding them out from the caliper bracket.
3. Remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
4. Check the rotor surface for warping using a dial indicator; replace if warped beyond specifications (usually 0.002 inches).
5. Install new rotors, ensuring they are clean and free of debris.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Inspect the old brake pads for thickness; replace if they are below manufacturer's minimum thickness.
2. Apply brake grease to the back of the new brake pads to reduce noise and improve performance.
3. Install new brake pads into the caliper bracket.

4. Reassemble Components

Sub-steps:
1. Reattach the brake caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer’s specified torque.
2. Reinstall the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle and Torque Lug Nuts

Sub-steps:
1. Lower the vehicle back to the ground.
2. Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque value (typically around 76 ft-lbs for a Corolla).
