Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the master cylinder reservoir and remove the cap.
Inspect the brake fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as per manufacturer specifications).
Replace the cap securely.

3. Inspect and Repair Brake Lines

Tools Required: Wrenches, brake line flaring tool (if replacement is needed)
Visually inspect all brake lines and hoses for cracks or leaks.
Tighten any loose connections and replace any damaged lines or hoses as necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, catch container
Start with the wheel farthest from the master cylinder (usually the passenger rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper, allowing fluid and air to escape.
Close the valve before the assistant releases the pedal. Repeat until no air bubbles appear in the fluid.
Move to the next wheel and repeat the process until all brakes are bled.

5. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel and inspect the brake pads and rotors for wear.
Replace worn brake pads and resurfacing or replace rotors as necessary.
Torque all components to manufacturer specifications.
