Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Inspect for Leaks

Visually inspect brake lines, calipers, and wheel cylinders for any signs of leaking brake fluid.
If leaks are detected, replace the damaged components.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing.
Locate the brake bleeder valve on each brake caliper.
Attach clear tubing to the bleeder valve and place the other end in a container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve slowly to allow fluid and air to escape, then close the valve before the assistant releases the pedal.
Repeat this process until no air bubbles are present in the fluid.
Repeat for all four wheels, starting from the wheel farthest from the master cylinder (usually the right rear).

5. Replace Brake Pads and Rotors (if necessary)

If pads or rotors are worn beyond specifications, replace them:

Remove the wheel and tire.
Unbolt the caliper and hang it from the suspension using a wire.
Remove the old brake pads and inspect the rotor for wear.
Replace the rotor if necessary, ensuring proper torque specifications for the caliper bolts.
