Do school buses have anti lock brakes?
Do school buses have anti lock brakes?
On March 1, ABS will be standard on new air-braked school buses. Pricing will be included in the overall base price of the vehicle and will vary by bus manufacturer and by ABS system specified.
How should you brake in a bus with ABS brakes?
ABS helps to avoid wheel lock up and maintain control of the bus. Were not saying that you will be able to stop any faster with ABS, but it should allow you to steer around an obstacle while braking, and avoid skids caused by over braking. When you drive a vehicle with ABS, you should brake normally.
What kind of air brake does a school bus have?
The 121 air brake system is the standard on a school bus and must be tested during a motor vehicle inspection. The test checks out the check valves which hold air in the tanks when another is drained.
What do you need to know about driving a school bus?
With that being said, every bus driver will need to accurately and meticulously ensure that the brakes on their school bus are safe. During the course of this training program we will demonstrate many important brake tests, the maintenance of brakes and the difference between hydraulic and air brakes.
Why are my brakes not working on my school bus?
This could be caused by a number of factors within the break caliper system; for example rotors, and or the brake shoes on the bus may not be working properly and need maintenance. Also, if there is an unusual feel, or a delayed stopping action, when applying the brakes, it is also an indication that there is a problem with the brakes.
What should I know about my air brake system?
-Brakes need adjusting, lubricating or relining. -Low air pressure in the brake system (below 60 psi). -Brake valve delivery pressure below normal. -Wrong size actuators and/or slack adjusters. -Failure of part of a dual air system. -If remote mounted brake valve, check linkage.
How are brakes applied on a school bus?
Compressed air activates the brakes and causes the bus too stop. a)Brakes are applied by pushing gently on the brake pedal. The heart of the air brake system is the compressor, which is often directly coupled to the engine.

During the course of this training program we will demonstrate many important brake tests, the maintenance of brakes and the difference between hydraulic and air brakes.
Where is the parking valve on a school bus?
The parking valve is typically located on the dash. With normal system pressure, pushing the valve “in” causes air to flow to the parking (emergency) side of the double air chamber, retracting the push rod against its applying spring and releasing the brakes. The parking/emergency system is spring applied and air released.
