An automatic slack adjuster or manual slack adjuster conversion which automatically adjusts the brakes incorporating a monitoring system that monitors the operation and adjustment of air powered brakes as used on vehicles. The system monitors the travel of the brake components, and when needed uses electromagnetic or pneumatic power to provide adjustment of the vehicle's brakes. Using groups of visual indicators to create a visual dashboard display of all brakes on the vehicle, the driver is provided with immediate and accurate brake operation and adjustment information. The visual indicators are controlled by multi-range position detectors that are incorporated into the automatic slack adjuster or conversion unit. Each position of the multi-range position detector activates an individual visual indicator providing precise range of adjustment indications each time the brakes are applied. If brakes are applied and no indication of brake operation appears on the display unit, the driver is immediately informed that the brake system is malfunctioning. The system is capable of informing and alerting the driver of numerous maintenance and safety problems before they can cause expensive repairs or an accident.
An improved system for automatically adjusting and concurrently monitoring the operation and adjustment of a vehicle's brakes providing a display indication indicative of a position of each brake's push rod as said brake's push rod relates to the operation and adjustment of said vehicle's brakes, said system comprising:
On a vehicle equipped with brakes that use compressed air from an air chamber to provide the
An improvement to a braking system for a motorized vehicle that includes brake drums and brake shoes and uses pressurized air to urge an engaging device to extend which in turn expands the brake shoes therein causing said brake shoes to contact the brake drums creating friction and stopping said motorized vehicle upon actuation of the brake pedal, the improvement is a system for the monitoring of brake operation and adjustment which incorporates a brake adjustment system that can be built into said brake system or added on at a latter time, the system comprises:
