Zorluk: OrtaBraking Systems and ABS

Before starting a journey, a driver must confirm that the vehicle's braking system is working safely and effectively. In which order should these checks be performed?

  1. 1Press the footbrake pedal firmly while stationary to ensure it feels resistant and not spongy or slack.
  2. 2Check all surroundings and move off slowly in a safe, clear area.
  3. 3Apply the footbrake gently while the vehicle is travelling at low speed.
  4. 4Confirm that the vehicle stops smoothly and does not pull to one side.

Cevap

1. Press the footbrake pedal firmly while stationary to ensure it feels resistant and not spongy or slack. 2. Check all surroundings and move off slowly in a safe, clear area. 3. Apply the footbrake gently while the vehicle is travelling at low speed. 4. Confirm that the vehicle stops smoothly and does not pull to one side.
According to the Official DVSA standards and Highway Code, brake functionality must be tested systematically. The driver starts with a static check to ensure the pedal is firm (not spongy or slack). Once static pressure is confirmed, the driver moves off slowly in a safe area, applies the footbrake gently, and confirms that the vehicle stops effectively without pulling to one side.

Adım Adım Çözüm

1
Perform the static pedal test before the vehicle moves.
Hydraulic integrity is confirmed if the pedal does not sink or feel spongy.
Moving off with failed hydraulic pressure or severe fluid leaks poses an immediate danger.
2
Set the vehicle in motion slowly in a safe environment.
The car moves at a controlled crawl suitable for testing.
Dynamic brake testing requires movement but should never be conducted at high speeds or in busy traffic.
3
Depress the footbrake pedal gently while moving.
Brake friction is engaged and decelerates the car.
Testing the pedal under light load verifies that friction pads and calipers respond correctly.
4
Assess vehicle tracking and deceleration smoothness during the stop.
Even brake distribution across all wheels is verified.
If the vehicle pulls to one side, it indicates uneven brake wear, seized calipers, or unbalanced braking pressure.
