Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the ignition is off.
Safety: Engage the parking brake and wear safety glasses.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, clean funnel.
Remove the cap from the brake fluid reservoir.
Check the fluid level; if it is below the minimum mark, add the correct type of brake fluid (typically DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect for Leaks

Tools Required: Flashlight.
Visually inspect all brake lines, calipers, and wheel cylinders for signs of fluid leakage.
If leaks are found, replace the damaged component (line, caliper, or cylinder).

4. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench, container for old brake fluid.
Start with the brake farthest from the master cylinder (usually 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 several times, then hold it down while you close the valve.
Repeat until no air bubbles appear in the fluid; then move to the next wheel.
Ensure to top off the brake fluid reservoir as needed during this process.

5. Replace Worn Components (if necessary)

Tools Required: Socket set, torque wrench, jack stands.
If brake pads or rotors are worn, remove the wheel and brake caliper.
Replace the pads or rotors as needed and reassemble, ensuring to torque bolts to factory specifications.
