Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow the brake system to cool if recently used.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rags
Open the master cylinder reservoir cap.
Inspect the brake fluid level; if low, clean the area around the cap to prevent contamination, then refill with the correct type of brake fluid specified in the owner's manual.
Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing, brake fluid
Start with the brake furthest from the master cylinder (usually the right rear).
Connect the clear tubing to the bleeder valve and place the other end in a container.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow fluid to escape until no air bubbles are visible, then close the valve.
Repeat this process for each brake caliper in the following order: right rear, left rear, right front, left front.
Ensure the brake fluid reservoir remains filled during the process.

4. Inspect and Replace Components

Tools Required: Socket set, torque wrench
Check for damaged or worn brake lines, calipers, and hoses.
If any components are found defective, remove them using the socket set, replacing them with new parts.
Torque all bolts to the manufacturer's specifications.

5. Test Drive and Final Check

Tools Required: None
After repairs, take the vehicle for a test drive to ensure the brakes feel firm and responsive.
Re-check fluid levels and for leaks after the test drive.
