Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Check the master cylinder reservoir. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect for leaks when refilling.

3. Bleed Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Attach clear tubing to the bleeder valve on one of the brake calipers.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close the valve before the pedal is released.
Repeat on all brake calipers (start from the farthest from the master cylinder).
Ensure the brake fluid reservoir remains full during the bleeding process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, jack, jack stands
Remove the wheel to access the brake components.
Inspect the brake pads and rotors for wear. Replace if worn beyond specifications.
Check brake hoses for integrity; replace if damaged or swollen.
Reassemble the wheel and lower the vehicle. Torque lug nuts to manufacturer specifications.

5. Test Brake Performance

Tools Required: None
Start the vehicle and pump the brake pedal to ensure it feels firm.
Perform a test drive to check braking effectiveness and ensure no spongy feeling remains.
