Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and ensure the engine is off.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4, as specified in owner’s manual)
Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top it off to the recommended level.
Check for any visible leaks around brake lines and connections.

3. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench that fits the bleeder screws, a container for old brake fluid.
Starting from the wheel farthest from the master cylinder (usually the right rear), attach the bleeder kit.
Open the bleeder screw and have an assistant pump the brake pedal several times until no air bubbles are present in the fluid.
Close the bleeder screw and repeat for the remaining wheels in the order: right rear, left rear, right front, left front.
Ensure to keep the master cylinder topped up during the bleeding process to avoid introducing air back into the system.

4. Inspect and Replace Brake Pads/Rotors (if necessary)

Tools Required: Jack and jack stands, lug wrench, socket set.
Raise the vehicle and remove the wheel to access the brake components.
Inspect the brake pads and rotors for wear. Replace pads if they are worn below the manufacturer’s specification.
If rotors are warped or below the minimum thickness, replace them as well.
Reassemble the brakes, ensuring all components are properly secured.

5. Check the Master Cylinder

Tools Required: Wrench set, fluid catch container.
Inspect the master cylinder for leaks or corrosion.
If the master cylinder is faulty, remove it from the brake booster by disconnecting the brake lines and unbolting it.
Install a new master cylinder, ensuring to properly torque the mounting bolts as per specifications.
