Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Locate the brake fluid reservoir, usually found near the back of the engine bay.
Clean around the reservoir cap to prevent contamination before opening.
Remove the cap and check the fluid level against the markings on the reservoir.
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 recommended level.
Replace the cap securely.

3. Inspect for Leaks

Tools Required: None specifically, but a flashlight may help
Visually inspect brake lines, calipers, and the master cylinder for any signs of leakage.
If leaks are found, identify the source to determine if a line, caliper, or master cylinder replacement is needed.

4. Replace Brake Components if Necessary

Tools Required: Socket set, wrenches, torque wrench, brake cleaner, new brake pads/rotors (if applicable)
If brake pads are worn down, remove the wheel and caliper to access the pads.
Replace pads and rotors if they are worn beyond specifications.
Reassemble all components and torque to manufacturer specifications.

5. Final Checks

Check the brake fluid level again after any repairs and top off if necessary.
Test the brake pedal for proper firmness and response.
