Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Open the master cylinder reservoir cap.
If the fluid is low or contaminated, remove the old fluid with a turkey baster.
Refill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flaring tool (if needed).
Visually inspect brake lines for corrosion, cracks, or leaks.
Tighten any loose fittings and replace any damaged lines.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, catch container.
Start with the wheel farthest from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow fluid and air to escape, then tighten the valve.
Repeat until no air bubbles appear in the fluid.
Move to the next wheel and repeat the process (left rear, right front, left front).

5. Inspect Brake Components

Tools Required: Jack, jack stands, lug wrench, torque wrench.
Remove the wheels and inspect brake pads for thickness and wear.
Check rotors for warping or scoring; replace if necessary.
Replace pads if they are worn down to the replacement indicators.

6. Final Assembly

Reinstall wheels and torque lug nuts to the manufacturer's specification.
Replace the master cylinder reservoir cap securely.
Test the brake pedal for firmness before driving.
