2
Check brake pad thickness and condition for uneven wear.
3
Examine brake calipers for proper function and any sticking.
4
Assess suspension components including control arms and bushings for wear or damage.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

Check Rotors:
- Remove the brake caliper using a socket set and hang it using a bungee cord (do not let it hang by the brake line).
- Remove the brake rotor by unscrewing the retaining bolts.
- Measure rotor thickness and check for warping. If warped, replace with new rotors.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Lubricate the back of the new pads with anti-seize compound.
- Install new brake pads in the caliper bracket.

4. Reassemble Components

Reinstall the brake rotor and caliper. Torque caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and lug nuts, and torque to manufacturer's specifications (usually around 76-80 ft-lbs).

5. Final Checks

Lower the vehicle and check the brake fluid level in the master cylinder.
Test the brake pedal for firmness before driving.
