Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves during the process.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rag.
Check the brake fluid level in the master cylinder reservoir.
If low, add the appropriate brake fluid (DOT 3 or 4 as specified in the owner's manual) until it reaches the recommended level.
Clean any spilled brake fluid immediately to prevent damage to vehicle surfaces.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, wrench for bleeder valve, container for fluid.
Starting with the wheel furthest from the master cylinder (usually the right rear), attach the hose to the bleeder valve.
Have an assistant press the brake pedal slowly and hold it down.
Open the bleeder valve to allow the fluid and air to escape. Close the valve before your assistant releases the pedal.
Repeat until the fluid runs clear and no air bubbles are present, moving to the next wheel in the order: right rear, left rear, right front, left front.
Check and refill the master cylinder reservoir as needed during this process.

4. Inspect and Replace Components

If bleeding does not resolve the issue, inspect brake lines and hoses for leaks and deterioration.
Replace any damaged hoses or lines as necessary.
Check the condition of the brake pads and rotors. Replace worn components according to specifications.
