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.
