Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before proceeding.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid funnel, clean rag
Locate the brake fluid reservoir (usually marked with a brake symbol).
Clean the area around the reservoir cap to prevent contamination.
Open the cap and check the fluid level against the minimum and maximum marks.
If low, use a funnel to add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) until it reaches the maximum mark.
Replace the cap securely.

3. Inspect for Leaks

Tools Required: Jack and jack stands (if needed for access)
Visually inspect all brake lines, calipers, and wheel cylinders for any signs of fluid leaks.
If leaks are found, replace the faulty components (brake lines, calipers, or wheel cylinders).

4. Replace Brake Fluid (if contaminated)

Tools Required: Brake fluid bleeder kit, wrench, container for old fluid
Remove the old fluid from the brake fluid reservoir using a turkey baster or siphon.
Refill with new brake fluid.
Bleed the brake system starting from the furthest wheel (usually rear passenger side) to the closest (front driver side) to remove air.
Ensure that the fluid level remains above the minimum mark throughout the process.

5. Test and Inspect Brake Components

Tools Required: Brake pad gauge, torque wrench
Inspect brake pads and rotors for wear and thickness.
Replace any worn components.
Reassemble any removed components and torque bolts to manufacturer specifications.
