Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Refill Brake Fluid

Tools Required: Clean cloth, funnel, brake fluid (DOT 3 or DOT 4 as specified in the owner's manual)
Locate the brake fluid reservoir, typically found near the back of the engine bay.
Clean the area around the reservoir cap to prevent contamination.
Open the reservoir cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, use a funnel to add the appropriate brake fluid to the reservoir. Do not overfill.
Replace and securely tighten the reservoir cap.

3. Inspect for Leaks

Examine brake lines, hoses, and connections for signs of fluid leakage.
If leaks are found, replace the damaged components.
Ensure all connections are secure and free from corrosion.

4. Bleed the Brakes (if necessary)

Tools Required: Brake bleeder kit, wrench, container for old fluid
Start at the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit to the bleeder valve on the brake caliper.
Open the valve and have an assistant press the brake pedal.
Close the valve before the pedal is fully released to prevent air from entering.
Repeat until clear fluid is seen without bubbles, then move to the next wheel in order (left rear, right front, left front).

5. Test Brake Function

After completing the above steps, check the brake pedal feel before starting the vehicle.
Start the vehicle and perform a low-speed test drive to ensure brakes are functioning properly.
