Safety check category B


1. Check the brake booster.
With the engine off, press the brake pedal repeatedly with medium pressure until the booster reserve is depleted. At least two brake applications should have a power-assisted feel before the pedal hardens noticeably. A pedal that feels hard immediately, or after only one brake application, may have a vacuum leak or a low level of engine vacuum. Then start the engine. The engine will now create a new vacuum, making the pedal soften.

2. Is it safe to drive with a non-working brake booster?
Because of reduced braking power, it is considered not safe. Besides, the brake pedal will be very hard. Check the level of brake fluid. Visual control in the engine compartment.

3. Check the brake fluid.
Check the fluid level under the hood of the car.
4. What do you do if you are low on brake fluid?
The brake system is using more fluid than normal because the brake pads might be worn. It may also be due to a leakage. Bring the car to a workshop.

5. Check if the brakes are directionally stable.
Find a straight, flat and traffic-free road, rest your hands lightly on the steering wheel and gently and gradually apply the brakes. The car should not swerves to one side.

6. What might be the reason if the car is swerving to one side (previous question)?
If you find the vehicles swerves to one side, that could mean that one of your brake linings is more worn and your brakes could require and adjustment. Check the dual hydraulic circuits brake system dashboard warning light. Identify the warning light.

7. What do you do if the warning light, in previous question, starts to light during driving?
Stop and then try to find out what triggered the warning. (The dual hydraulic circuit brake system might be at fault, you are low on brake fluid, or it might be a faulty controller.)

8. What is a two-circuit braking system?
It is required to have a two-circuit braking system in Norway. One circuit runs on both front wheels and a rear wheel, the other runs on both front wheels and the other rear wheel. The reason it is divided into two circuits is that if one circuit stops working you still have a circuit that works so you can brake the vehicle. If there is something wrong with one circuit, the car will pull towards one of the sides when braking. The warning light (!) Will also light up in the instrument panel.

9. Check that the warning light for the two-circuit braking system works.
​​You check that the two-circuit braking system works by turning on the engine of the car and seeing that the warning light comes on and goes out by itself. Pull the handbrake up and down and see that the lamp (!) Switches on and off.

10. Check the ABS dashboard warning light.
A lamp with the writing “ABS” lights up when you start the engine, and should then turn itself off after a few seconds.

11. Is it safe to continue driving if the lamp starts to illuminate while driving?
Yes, but the error should be corrected.
