Study Notes

Stopping and Tread Depth

At 55 mph, it takes approximately 6 seconds to come to a complete stop.
Minimum tread depth for front tires is 4/32 inches; for rear tires, it is 2/32 inches.

Vehicle Control and Brake Testing

Steering wheel play should not exceed 10 degrees (2 inches in a 20-inch wheel).
To test air brakes, pump brakes three times and hold on the fourth.
Stopping distance calculation involves perception time, reaction time, and braking distance.

Emergency Procedures and Safety Equipment

If Anti-lock Braking System (ABS) fails, do not stop immediately but service the vehicle soon.
Trucks must carry three caution triangles and an ABC fire extinguisher.

Driving Techniques and Legal Requirements

Engine braking involves downshifting to slow the vehicle without using brakes, especially downhill.
When making a right turn, swing into the lane of the road you're turning onto.
Always honk before changing lanes; check mirrors after lane change is complete.

Vehicle Inspection and Maintenance

Brake testing involves driving at 5 mph and applying brakes to ensure stopping ability.
Check for engine belt play; should not exceed 3/4 inch.
Caution triangles should be placed 10 feet and 100 feet away from the vehicle.

Retarders and Air Brake Systems

Retarders assist in slowing the vehicle, reducing brake use; types include exhaust, engine, hydraulic, and electric.
Safety relief valve is set to open at 150 PSI, ensuring air pressure regulation in the first tank.

Air Compressor Functionality

Air compressor governor controls the operation of the air compressor regarding pumping air into storage tanks.
Governor cut-out level is 125 PSI and cut-in level is 100 PSI.

Brake Types and Warnings

Foundation brakes are located at each individual wheel for effective braking.
Low Air Pressure Warning activates at 55 PSI; spring brakes engage at air pressure dropping to 20-45 PSI.

General Vehicle Practices

Always drain air tanks daily after driving to maintain performance.
There should be one tie-down for every 10 feet of cargo; a minimum of two tie-downs is necessary for loads of 5 feet or less.
There should be a maximum of 1 inch of play in leaf springs.
