Solution

1. Preparation

Gather all necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid tester, brake fluid, funnel.
Check the brake fluid level; if it’s low, top it off with the recommended brake fluid type.
If the fluid appears dirty or contaminated, proceed to replace it:
- Locate the brake fluid reservoir and remove the cap.
- Use a turkey baster to remove old fluid from the reservoir.
- Fill the reservoir with fresh brake fluid to the maximum level.

3. Inspect Brake Lines and Components

Tools Required: Wrench set, brake line wrench, flashlight.
Visually inspect the brake lines and connections for leaks or damage.
Tighten any loose connections and replace any damaged lines with new brake lines.
Ensure all fittings are secure and leak-free.

4. Inspect Brake Pads and Rotors

Tools Required: Jack and jack stands, lug wrench, socket set.
Lift the vehicle and remove the wheel to access the brake assembly.
Check the thickness of the brake pads; if worn below the minimum thickness, replace them.
Inspect the rotors for scoring or warping; resurface or replace if necessary.

5. Test the Brake Booster

Tools Required: Vacuum pump (if needed).
With the engine off, pump the brake pedal several times to deplete the brake booster vacuum.
Start the engine and observe if the brake pedal drops slightly, indicating the booster is functioning properly.
If there is no drop, the brake booster may need replacement.
