Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted on jack stands.
Disconnect the battery to ensure safety when working on the braking system.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rag
Inspect the brake fluid reservoir for the correct level. If low, refill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
Clean any spills immediately to prevent damage to vehicle components.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Attach the clear tubing to the bleeder valve on the brake caliper.
Have an assistant press the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it before the pedal is released.
Repeat this process until no air bubbles are seen in the fluid.
Repeat for all four brakes, starting from the furthest wheel from the master cylinder.

4. Inspect and Repair Brake Components

Tools Required: Socket set, torque wrench, brake cleaner
Inspect the brake lines and hoses for any signs of wear or leaks. Replace any damaged sections.
Check the brake pads and rotors. Replace them if they are worn beyond specifications.
Reassemble any components removed during inspection and ensure all fittings are torqued to the manufacturer's specifications.
