Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during repair.

2. Check and Top Off Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and inspect fluid level.
If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Secure the cap back on.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, container for fluid, clear tubing.
Start with the brake farthest from the master cylinder (usually the rear passenger side).
Attach the tubing to the bleeder screw and place the other end in a container.
Have an assistant press the brake pedal several times, then hold it down.
Open the bleeder screw to allow fluid and air to escape, then close it before the assistant releases the pedal.
Repeat until no air bubbles appear in the fluid, then move to the next wheel and repeat the process in the order: rear passenger, rear driver, front passenger, front driver.
Ensure to keep the master cylinder reservoir topped off during this process to prevent introducing air into the system.

4. Inspect and Replace Brake Components (if necessary)

If pads or rotors are worn, replace them by:
1. Removing the wheel.
2. Unbolting the caliper and hanging it securely.
3. Removing the old brake pads and inspecting the rotor for damage.
4. If the rotor is worn, replace it with a new one.
5. Install new brake pads and reassemble the caliper.
6. Torque all bolts to the specified values provided in the vehicle service manual.
