Three Types of Brakes a Truck Repair Service Can Afford to Fix
Fleet operators in Brisbane and other places around the globe are known to spend a substantial amount of money on brake repairs or replacements, which could be easily avoided with thoughtful and proactive planning, and by hiring a truck repair service for preventive maintenance. Latest market research statistics suggest that twenty-nine in every hundred roadside accidents associated with trucks are caused by various brake issues. The disc and drum brakes of your truck can easily wear down over a period of time if not properly maintained and serviced, given the friction, pressure, and heat they are constantly being exposed to. Brake issues causing vehicle breakdowns are typically the result of internal water contamination or air leaks, which allows the air ducts in your truck to freeze up eventually in the winter season.
Trucks are equipped with quintessentially complicated braking systems, which can be classified into three broad categories, namely; emergency braking system, spring or parking braking system, and air or service braking system.
- Air brakes
Service brakes make use of pressurized air for applying the brakes and are typically employed during routine driving. One of the most frequently found air brakes in trucks are known as the S-cam brakes, due to the fact that the mechanism utilized for pushing the brake shoes to move the drums is essentially S-shaped. On the contrary, the disc brakes and wedge brakes are somewhat of a less standard feature found in the commercial trucks. Present day trucks are also equipped with an anti-lock braking system (ABS) that prevents the wheels from getting jammed in the events of hard braking.
Make a point to visit a well-established truck repair in Brisbane (or wherever you may require) for repairing, servicing, or replacing your air brakes.
- Spring brakes
The various brakes that comprise the parking braking system are made to activate with the help of controlled and systematic loss of the net amount of pressure exerted by the air. This loss can be made to happen by means of engaging or disengaging a manual control, such as a push-pull knob fitted in the driver cabin, or it can make use of a purpose-designed air leak. Air pressure keeps these brakes in an open position during routine driving conditions, which get activated when the pressure applied by the springs becomes greater than that of the air. The spring braking system is usually used to secure the truck when stationary or parked.
Remember to call a well-known truck repair in Brisbane (or wherever you may want) to repair, service, or replace your parking brakes.
- Emergency brakes
The emergency brakes engage the spring brakes as soon as the air pressure starts to decrease in the service braking system. The parking brakes spring into action once the air pressure begins to fall below twenty to forty-five PSI (pound per square inch) in the air reservoirs of the vehicle, and thus, stops the truck eventually. These brakes can be disengaged at times by utilizing the air stored in an auxiliary tank, provided a truck is armed with any such facility, to move it away from a potentially hazardous situation. You can also apply these brakes manually in the unforeseen event of a brake failure and as long as the automobile has a factory-fitted modulating valve. This particular valve permits you to apply the spring or parking brakes in a gradual fashion with the help of an emergency lever in your dashboard for decelerating the truck. Never forget to place the lever fully on, and secure it by a locking device, when parking a vehicle armed with a modulating valve.
You should always get in touch with a trustworthy truck repair company only for repairing, servicing, or replacing your emergency braking system in Brisbane (or wherever you may want).
