Solution

1. Preparation

Gather tools and parts.
Ensure vehicle is on a flat surface and engage the parking brake.

2. Brake Fluid Inspection

Tools Required: Brake fluid tester, rags.
Check brake fluid level in the master cylinder.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect fluid for contamination; if dirty, perform a complete brake fluid flush.

3. Brake Pad and Rotor Replacement

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Lift the vehicle and remove wheels.
Remove caliper bolts and lift the caliper off the rotor (support it with a hanger to avoid strain on the brake line).
Remove old brake pads and inspect the rotor.
If worn or damaged, replace rotors as necessary (ensure they are within the manufacturer's specifications).
Install new brake pads, ensuring they are properly seated in the caliper bracket.
Reattach the caliper and torque bolts to manufacturer specifications.

4. Brake Line and Caliper Inspection

Tools Required: Socket set, wrench set.
Inspect brake lines for wear or leaks; replace any damaged lines.
Check calipers for proper operation; if they are sticking, they may need to be rebuilt or replaced.

5. Brake Booster Test

Tools Required: Vacuum gauge.
With the engine off, pump the brake pedal until it feels firm.
Start the engine and press the brake pedal; it should depress easily. If not, the brake booster may be faulty and needs replacement.
