Many tractors have mechanical brakes, operated by a linkage and cam system instead of a master/slave fluid system. These brakes are located on the rear axles, and work independently, so that they may be used to steer the tractor in tight corners or to reverse the direction of travel. The brake pedals will interlock for road travel, so that one pedal is not accidentally engaged by itself, causing the tractor to spin while traveling at a high speed.
If you are driving a semi tractor with a trailer, the trailer knob for the brakes works in the same way. But if there is an air leak in the trailer, the tractor protection valve will make the trailer brakes set to protect the tractorâs air supply so you can still stop.The other system is the service brake system.This is the system that stops you when you push on the brake pedal.hen you push on the brake pedal it goes through the pedal valve, which modulates the air flow to the brake chambers. The brake chambers in turn push on the slack adjusters, which is the component that keeps the brakes in adjustment. There are different types of slack adjusters â manual and automatic.
