Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Check Brake Fluid Level

Tools Required: None
Inspect the brake fluid level in the master cylinder reservoir.
If the fluid is low, top it off with the manufacturer-recommended brake fluid.

3. Inspect Brake Lines and Components

Tools Required: Wrench set, flashlight
Check all brake lines for leaks or damage. Look for signs of wetness around fittings and hoses.
Inspect wheel cylinders and calipers for leaks. Replace any damaged components.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container for old fluid
Start at the wheel farthest from the master cylinder (usually the passenger rear wheel).
Attach the bleeder kit and open the bleeder valve while a helper presses the brake pedal.
Close the valve before the pedal is released. Repeat until fluid runs clear.
Move to the next wheel, following the sequence: passenger rear, driver rear, passenger front, driver front.

5. Replace Worn Components

Tools Required: Socket set, torque wrench
If brake pads or discs are worn beyond specifications, remove the wheel and replace them.
Torque the new components to the manufacturer's specifications.

6. Test the Brake System

Tools Required: None
Once repairs are made, start the vehicle and pump the brake pedal to restore brake pressure.
Test the brakes at low speeds to ensure proper function.
