Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4 as specified in the owner's manual)
Remove the master cylinder reservoir cap.
Inspect the brake fluid level; if low, refill to the recommended level.
Check the fluid condition; if contaminated, proceed to flush the system.

3. Inspect and Repair Brake Lines

Tools Required: Wrenches, brake line tool
Check all brake lines for corrosion, cracks, or leaks.
If leaks are found, replace damaged sections of the brake line.
Ensure all connections are tight and free from leaks.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container
Start with the brake furthest from the master cylinder (usually the right rear wheel).
Attach the clear tubing to the bleeder valve and place the other end into the container.
Open the bleeder valve while an assistant presses the brake pedal, allowing air and fluid to escape.
Close the valve before the pedal is released to prevent sucking air back in.
Repeat this process for each brake, moving from rear to front (right rear, left rear, right front, left front).
Check the brake pedal feel after bleeding.

5. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench
Check the brake pads for wear; if worn down to the minimum thickness, replace them.
Inspect the rotors; if they are warped or have excessive wear, replace or resurface them.
If the master cylinder shows signs of failure, remove and replace it following manufacturer specifications.
