Question 5051
For proper maintenance of the brake system, what should be done?
- Press the brake pedal all the way down to check its effectiveness.
- Check the brake fluid level.
- Lubricate the discs periodically.
Show answer and explanation
Correct answer: Check the brake fluid level.
Passenger car brakes are usually hydraulic. When you press the pedal, you push the brake fluid, and its pressure presses the pads against the rotors. If the fluid is low, braking force decreases. That is why you check its level regularly. Never grease the rotors, because grease reduces the pads' grip. In the diagram, the red and blue lines carry fluid from the master cylinder to all four wheels.
