Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Put on safety goggles and gloves.

2. Check Brake Fluid

Remove the master cylinder cap and inspect the brake fluid level.
- Tools Required: None
If fluid is low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified).

3. Inspect Brake Lines and Components

Examine all brake lines for any signs of leaks or damage.
- Tools Required: Visual inspection tools, flashlight
Tighten any loose fittings and replace damaged lines if necessary.

4. Bleed the Brakes

Begin at the wheel farthest from the master cylinder (usually the passenger rear).
- Tools Required: Brake bleeder kit, wrench
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to let air and fluid escape, then close the valve before releasing the pedal.
Repeat for each wheel in sequence (passenger rear, driver rear, passenger front, driver front) until no air bubbles are present.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Remove the wheel and inspect the brake pads and rotors.
- Tools Required: Socket set, torque wrench
Replace brake pads if they are worn down to less than 3mm thickness.
Replace rotors if they are scored, warped, or below the minimum thickness specification.

6. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Test the brake pedal feel by pressing it several times with the engine running.
Check for any leaks after bleeding the brakes.
