What is the air brake test?
What is the air brake test?
The Air Brake Test covers the different braking systems and tests you on your knowledge of parking brakes, service brakes, emergency brakes, reading low pressure warnings, checking pressure gauges, and more.
What is the cut-in and cut-out air pressure for a standard air brake system?
Note: Cut-out pressure is normally 138 to 173 kPa (20 to 25 psi) above the cut-in pressure. Normal air brake system pressure range is around 690 to 828 kPa (100 to 120 psi). Drivers should know the normal pressure range of the vehicle they operate and should report any abnormal condition.
When you double your speed the demand on your brakes to come to a stop will increase by how much?
four times
Speed – As vehicle speed increases, the stopping distance increases at a rate that is greater than the change in speed. For example, when speed is doubled, the stopping distance increases by four times (See Diagram 7-2).
What psi do air brakes release?
Air brakes are typically used on heavy trucks and buses. Typical operating pressure is approximately 100–120 psi or 690–830 kPa or 6.9–8.3 bar. A compressed air brake system is divided into a supply system and a control system.
How many questions are on the Ontario air brake test?

How long should air brakes take to build pressure?
45 seconds
Air pressure build-up from 85 psi to 100 psi should take 45 seconds or less. While driving, observe the air pressure gauge during build-up to ensure proper air system operation. braking, pull over at a safe place and perform the 2 minute / 5 psi leakage test.
How do air brakes get power?
The smaller the space into which air is squeezed, the greater the air’s resistance to being squeezed. This resistance creates pressure, which is used to gain mechanical advantage.
How long will it take you to stop with heavy braking if you are traveling 65 mph?
Braking distance is the distance it takes to stop your vehicle once you apply the brakes. At 65 mph, it takes an additional 5.5 seconds or about 525 feet of actual brake application to stop your vehicle.

How is the air brake connected to the brake assembly?
Holes or cracks that are caused by impact or other forms of damage mean the air brake chamber is defective. The brake chamber is connected to the brake assembly by a pushrod, yoke, clevis pin, slack adjuster and camshaft. Slack adjusters act as levers that increase the force of the air brake chambers. Their effective length is critical.
