Solution

1. Preparation

Tools Required: Socket set, wrench set, brake fluid, brake bleeder kit, jack stands, and safety goggles.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety goggles and gloves while working on the braking system.

2. Check and Refill Brake Fluid

Locate the master cylinder reservoir.
If the fluid is low, add the appropriate type of brake fluid (consult owner’s manual for specifications).
Inspect for leaks at the reservoir cap and around the master cylinder.

3. Inspect Brake Lines and Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect all brake lines for leaks, corrosion, or damage.
If leaks are found, replace the affected brake lines or components.

4. Bleed the Brakes

Tools Required: Brake bleeder kit.
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit to the brake caliper, and have an assistant pump the brake pedal.
Open the bleeder valve, allowing fluid and air to escape. Close the valve when fluid flows without bubbles.
Repeat for all wheels in the correct order (right rear, left rear, right front, left front).

5. Replace Worn Brake Components (if necessary)

If brake pads or rotors are worn beyond specifications, remove the wheel and brake caliper.
Replace worn brake pads or rotors and reassemble.
Torque all bolts to manufacturer specifications.

6. Final Checks

Recheck brake fluid level in the master cylinder after bleeding the brakes.
Test the brake pedal for proper firmness before driving.
