Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Put on safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, turkey baster, funnel.
Remove the cap from the master cylinder reservoir and use the turkey baster to extract old brake fluid.
Dispose of the fluid properly.
Refill the master cylinder with new brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Identify and Repair Leaks

Tools Required: Wrenches, brake line repair kit.
Visually inspect all brake lines, hoses, and connections for signs of leaks.
If a leak is found, replace the damaged brake line or hose using appropriate fittings.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container, wrench.
Start with the brake furthest from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it.
Repeat until clean fluid comes out without bubbles, then move to the next brake in the order: left rear, right front, left front.

5. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, jack, jack stands.
Inspect brake pads, calipers, and rotors for wear.
Replace worn brake pads or damaged calipers as necessary.
Reassemble the wheel and torque the lug nuts to the manufacturer's specifications.

6. Recheck Brake Functionality

Start the vehicle and pump the brake pedal several times to ensure firmness.
Conduct a test drive in a safe area to confirm that braking performance is restored.
