Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Check and Top Off Brake Fluid

Tools Required: Clean funnel, brake fluid (DOT 3 or DOT 4).
Open the master cylinder reservoir cap.
Inspect the brake fluid level; if low, add the appropriate brake fluid until it reaches the "Full" line.
Replace the reservoir cap securely.

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line wrench, rags.
Visually inspect all brake lines and hoses for any signs of wear or leaks.
If a leak is found, replace the damaged section of the brake line or hose.
Bleed the brake system to remove any air pockets.

4. Brake Pad and Rotor Inspection

Tools Required: Jack and jack stands, socket set, torque wrench.
Lift the vehicle and remove the wheels to access the brake components.
Inspect brake pads for thickness; replace if worn down to less than 3mm.
Check rotors for scoring or warping; machine or replace if necessary.
Reassemble the brakes and wheels, ensuring all components are torqued to specification.

5. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, brake fluid.
Start at the farthest wheel from the master cylinder and work towards the closest.
Attach the clear tubing to the bleeder valve and submerge the other end in a container with brake fluid.
Open the bleeder valve and have an assistant press the brake pedal several times, then hold it down.
Close the bleeder valve before the pedal is released. Repeat until no air bubbles appear in the fluid.
Repeat for each wheel.
