Study Notes

Braking Systems

The brake pedal is a component of the service braking system.
The most common foundation brake type is the S-cam drum brake.
Front wheel braking functions effectively under all conditions.
Anti-Lock Braking Systems (ABS) enhance safety but do not diminish standard braking power.

Driving Techniques

To avoid overheating in hot weather, decrease speed.
In case of a vehicle stuck on railroad tracks, exit the vehicle and move away from the tracks.
During vehicle operation with a dual brake system, wait for the air compressor to reach a minimum of 100 psi before driving.

Vehicle Inspection

Check belts in the engine compartment for tightness during pre-trip inspections.
For automatic transmission fluid level checks, the vehicle may need to be running.
Inspect slack adjusters on S-cam brakes by chocking the wheels and releasing the parking brake.
Rims with welding repairs are deemed unsafe.

Reaction and Distance

Reaction distance is the space traveled from spotting a hazard to applying brakes; average driver's reaction time ranges from three-quarters of a second to one second.

Air Brake Systems

Dual air brake systems feature separate air tanks, hoses, and lines.
A one-way check valve is crucial for maintaining air pressure in the event of a compressor leak.
The low air pressure warning signals activation occurs below 55 psi.
Maximum leakage rates for air brake tests: 2 psi for single vehicles, 3 psi for double combinations, and 6 psi for triple combinations.

Safety and Equipment

Mandatory emergency equipment includes spare electrical fuses.
Dollies with ABS should have malfunction lamps located on the left side.
In cold conditions, the alcohol evaporator must be checked and filled daily.

Legal Compliance

A driver with multiple licenses may incur a fine of up to $5,000.
Conviction for two serious traffic violations within three years results in a CDL suspension for at least 60 days.

Parking and Controls

The spring brakes should never be pressed down when activated.
Dual parking control valves allow a separate air tank to momentarily release spring brakes after pressure loss.
