Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top up with the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Inspect for Leaks

Visually inspect brake lines, calipers, and the master cylinder for any signs of leaks or damage.
Clean any spilled brake fluid as it can damage vehicle paint.

4. Test Brake Pressure Switch

Locate the brake pressure switch, typically near the master cylinder.
Disconnect the wiring harness and use a multimeter to check for continuity with the brake pedal depressed.
If defective, replace the brake pressure switch.

5. Examine ABS System

Check the ABS sensors on each wheel for damage or disconnection.
Inspect wiring harness for any signs of wear or short circuits.
If necessary, replace faulty sensors or repair wiring.
