It is the metal connector at the end of the hoses that supply air to the trailer brakes from the tractor.
Anti compounding valves are found in an air brake system on large commercial vehicles. These valves help to balance the pressure applied to the slack adjuster by simultaneously applying air to the spring brake relay when the service brake is pushed. The air is applied to the parking brake chamber as air pressure is applied to the service brake chamber thus releasing the parking brake the same amount that the service brake is applied thus "Balancing" the pressure in the brake chamber. This prevents excessive pressure from being applied to the service side and subsequently to the rod and slack adjuster. Thomas Moysey- owner A.B. CDL Training Center Waterford, CT
Three (3) psi/minute (single vehicle) or four (4) psi/minute in a combination vehicle. This is with the motor off, parking brake released, and service brakes applied.
the parking brake on caterpillar dump truck is spring applied and pressure released
No. The brakes are applied manually. A brake band squeezes a brake drum.
The air is held in tanks near each axle Air is put into lines from the "Service Valve" under the Brake Pedel. It rushes to a valve called a relay valve mounted very close to each axle and each brake. The air from the service valave causes the Relay valve to send air from the tanks to the brake chambers causing the brake chamber push rod to move.
It decreases.
The service brake is the one which applies the brakes - the emergency brake system is the system which releases the spring brakes.
Each wheel has a service brake assembly. The rear service brake assemblies include a parking brake.
check the parking brake cables, any applied tension, and condition of the brake shoes
There are several sources that offer brake repair service by a brake team, you should choose one that offer the least stress on you as they do the repair. Two names come to mind and they are Mienke Brake Repair Service and GMC Brake Service and their work is excellent.
