Solution

1. Preparation

Tools Required: Brake fluid, socket set, wrench set, turkey baster, brake bleeder kit, safety goggles, gloves.
Ensure the vehicle is on a flat surface and set the parking brake.
Wear safety goggles and gloves to protect from brake fluid.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder reservoir.
Use a turkey baster to remove any old brake fluid if it is contaminated.
Refill the reservoir with new brake fluid according to the manufacturer’s specifications (typically DOT 3 or DOT 4).

3. Inspect Brake Lines and Components

Visually inspect the brake lines for any signs of wear, cracking, or leaks.
Check the brake calipers for any signs of fluid leakage. If leaks are found, replace the calipers.
If the brake pads are worn down, replace them according to manufacturer specifications.

4. Bleed the Brake System

Begin at the wheel farthest from the master cylinder (typically the right rear).
Connect a brake bleeder kit to the bleeder valve on the caliper.
Open the bleeder valve and have an assistant press the brake pedal slowly until fluid comes out without bubbles.
Close the valve before the pedal is released to avoid sucking air back into the system.
Repeat for the left rear, right front, and left front wheels in sequence.
Ensure that the brake fluid level in the master cylinder does not drop below the minimum during the bleeding process.

5. Final Check

After bleeding, check the brake pedal feel. It should be firm and responsive.
Test drive the vehicle in a safe area to verify braking performance.
