What is an AUX brake?

What is an AUX brake?

This means a system that assists in stopping the apparatus other than the service brakes located at the wheel ends. Auxiliary braking can be accomplished through the action of the engine, the transmission, or other means acting on the apparatus drivetrain.

What is the engine braking effect?

Engine braking is basically the process of slowing the car down by releasing the accelerator and shifting down through gears, rather than using the footbrake. It restricts the air flow to the cylinders, sapping the energy and creating a braking force that will bring the car to a stop.

What are the benefits of ABS brakes?

Anti-lock brakes assist drivers to have better control and shorter stopping distances on slippery surfaces or through panic braking. The system monitors each wheels activity individually with the help of sensors. The brake pressure is then regulated to stop the wheels locking up and avoid slippage.

What kind of aux brake does a GMC C6500 have?

AUX BRAKE (Warning light comes on) 98 GMC C6500 AUX BRAKE (Warning light comes on) 98 GMC C6500

When does the GMC C6500 aux warning light and alarm sound?

If the system air pressure drops below 503 kPa (73 psi), when the ignition is on, the low air pressure switch turns on the warning lamp and the module sounds a constant tone alarm. If the coolant level becomes very low, the module also turns on the LOW COOLANT warning lamp and sounds an alarm at five beats per second.

When does the aux brake warning light and alarm sound?

This module turns on the PRIMARY BRAKE warning lamp on the instrument panel when the fluid level in the brake master cylinder is low, or when the flow of fluid from the power steering pump is low. If the module detects a malfunction in the auxiliary electric pump system, the module turns on the AUX BRAKE warning lamp and sounds a continuous alarm.

How does the brake alarm work on a GMC C6500?

Also, during the engine-running mode of operation and when the brakes are applied, the closed stoplamp switch sends a battery voltage signal to the alarm/brake booster module on the GRY wire. At the same time, the module senses battery voltage on the WHT wire from the brake switch.
