Solution

1. Preparation

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

2. Inspect and Top Up Brake Fluid

Tools Required: Brake fluid, funnel
Check the master cylinder reservoir for fluid level.
If low, add the appropriate type of brake fluid (consult owner's manual for specifications).

3. Inspect for Leaks

Tools Required: None
Visually inspect all brake lines and connections for signs of fluid leakage.
If leaks are found, identify the source and note the affected components for replacement.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, catch container
Start with the wheel farthest from the master cylinder (typically the rear passenger side).
Attach the tubing to the bleeder valve and place the other end in the catch container.
Open the bleeder valve and have an assistant press the brake pedal slowly. Tighten the valve before they release the pedal.
Repeat until no air bubbles are visible in the fluid.
Repeat the process for each wheel in the correct order (rear passenger, rear driver, front passenger, front driver).

5. Inspect and Replace Worn Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake components.
Check the brake pads; replace if worn below the manufacturer's specified thickness.
Inspect the rotors for warping or damage; replace if necessary.
Reassemble the wheel and torque the lug nuts to manufacturer specifications.
