Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Brake Fluid Inspection

Tools Required: Brake fluid tester or syringe.
Remove the master cylinder reservoir cap and check the brake fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Check for contamination in the fluid, which may require a complete brake fluid flush.

3. Brake Pad Replacement

Tools Required: Jack and jack stands, lug wrench, ratchet and socket set, torque wrench.
Jack up the vehicle and remove the wheels.
Remove the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads and replace them with new ones, ensuring they are properly seated.
Reassemble the caliper and torque bolts to the manufacturer's specifications.

4. Brake Rotor Inspection/Replacement

Check the rotors for any visible damage or warping.
If warped, remove the rotor using a socket set and replace it with a new rotor.
Ensure the new rotor is properly torqued to specifications.

5. Brake Line and Hose Inspection

Inspect brake lines and hoses for any signs of wear, cracks, or leaks.
If leaks are found, replace damaged brake lines or hoses immediately.

6. Brake Booster Testing

Tools Required: Vacuum gauge (if needed).
Test the brake booster by pressing the brake pedal with the engine off; it should feel firm.
Start the engine and press the pedal again; the pedal should drop slightly if the booster is functioning correctly.
