Diagnostic Steps

1
Inspect brake rotor condition for warping or uneven wear.
2
Check brake pads for wear and proper seating against the rotors.
3
Examine suspension components such as control arms, ball joints, and tie rods for wear or damage.
4
Verify tire balance and alignment.
5

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Brake Rotors

Remove the wheel using a socket set.
Unbolt the brake caliper and suspend it using wire to avoid stressing the brake line.
- Tools Required: Socket set, wire.
Remove the brake rotor by unscrewing any retaining screws.
Inspect the rotor for warping using a run-out gauge; replace if warped beyond specifications (generally above 0.002 inches).
Clean the hub surface and install new rotors, torquing to manufacturer specifications (usually around 10-15 Nm for retaining screws).

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the thickness of the pads; replace if below the minimum thickness (usually around 3 mm).
Apply brake grease to the back of the new pads to prevent squeaking and install them in the caliper bracket.
- Safety Warning: Ensure no grease contacts the friction surface of the pads.

5. Reassemble

Reattach the brake caliper over the new pads.
Reinstall the wheel and torque lug nuts to manufacturer specifications (usually 100-120 Nm).
Lower the vehicle and remove the jack stands.
