Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid tester, turkey baster.
Remove the cap from the master cylinder reservoir.
Use a turkey baster to remove old brake fluid from the reservoir.
Inspect the fluid for contamination (cloudiness or discoloration).
Refill with the appropriate type of brake fluid (usually DOT 3 or DOT 4, check owner's manual).
Safety Warning: Brake fluid is corrosive; avoid contact with paint and skin.

3. Check and Repair Brake Lines

Tools Required: Wrench set, brake line flaring tool (if necessary).
Inspect brake lines for any signs of wear, corrosion, or leaks.
If leaks are found, replace the damaged brake line with a new one.
Ensure all connections are tight and secure.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder screws.
Start at the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit, and open the bleeder screw while someone presses the brake pedal.
Close the bleeder screw before the pedal reaches the floor. Repeat until no air bubbles are visible in the fluid.
Move to the next wheel and repeat the process (left rear, right front, left front).

5. Inspect Brake Components

Tools Required: Torque wrench, socket set.
Remove the wheel to access brake components.
Inspect brake pads for wear; replace if thickness is below specification.
Check rotors for scoring or warping; resurface or replace as necessary.
Reassemble the wheel and torque the lug nuts to manufacturer specifications.

6. Test Brake Functionality

Reconnect the battery.
Start the vehicle and pump the brake pedal to restore pressure.
Test drive the vehicle in a safe area to ensure proper brake function.
