Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Remove the caliper bolts and carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper for any signs of damage; replace if necessary.
- Install new brake pads, ensuring they fit snugly in the caliper bracket.
Tools Required: Socket set, torque wrench, brake cleaner.

3. Examine and Resurface/Replace Rotors

Sub-steps:
- Check the rotor thickness with a caliper; if below minimum thickness, replace.
- If the rotor is within specs, clean the surface with brake cleaner and a lint-free cloth.
- If warped, machine or replace the rotors as necessary.
- Reinstall the rotor and ensure it is securely fastened.
Tools Required: Brake rotor gauge, brake cleaner.

4. Check and Replace Brake Fluid

Sub-steps:
- Inspect the brake fluid reservoir; if low or discolored, replace the fluid.
- Use a turkey baster to remove old fluid from the reservoir.
- Fill with the manufacturer-recommended brake fluid type (e.g., DOT 3 or DOT 4).
- Bleed the brake system to remove any air bubbles.
Tools Required: Turkey baster, brake fluid, brake bleeder kit.

5. Test Brake Booster

Sub-steps:
- With the engine off, pump the brake pedal several times to deplete vacuum.
- Start the engine; the pedal should drop slightly indicating proper function.
- If the pedal does not drop, inspect the brake booster and vacuum lines for damage and replace if necessary.
Tools Required: Vacuum gauge (optional).
