Forklift Brakes - A brake drum is where the friction is supplied by the brake shoes or brake pads. The pads or shoes press up against the rotating brake drum. There are several different brake drums kinds together with certain specific differences. A "break drum" will normally refer to if either pads or shoes press onto the interior outside of the drum. A "clasp brake" is the term utilized to describe whenever shoes press next to the exterior of the drum. Another type of brake, called a "band brake" uses a flexible belt or band to wrap around the exterior of the drum. Where the drum is pinched in between two shoes, it could be called a "pinch brake drum." Like a standard disc brake, these types of brakes are somewhat uncommon.
Before the year 1995, old brake drums required consistent modification regularly to be able to compensate for shoe and drum wear. "Low pedal" or long brake pedal travel is the dangerous outcome if adjustments are not done satisfactorily. The motor vehicle could become hazardous and the brakes could become ineffective if low pedal is mixed along with brake fade.
There are different Self Adjusting Brake Systems accessible, and they could be categorized within two major types, RAD and RAI. RAI systems have built-in devices that prevent the systems to recover when the brake is overheating. The most well known RAI makers are Bosch, AP, Bendix and Lucas. The most famous RAD systems comprise AP, Bendix, Ford recovery systems and Volkswagen, VAG.
The self adjusting brake will normally just engage whenever the lift truck is reversing into a stop. This method of stopping is suitable for use where all wheels use brake drums. Disc brakes are utilized on the front wheels of vehicles nowadays. By working only in reverse it is less likely that the brakes will be applied while hot and the brake drums are expanded. If tweaked while hot, "dragging brakes" can happen, which raises fuel consumption and accelerates wear. A ratchet tool that becomes engaged as the hand brake is set is one more way the self adjusting brakes could operate. This means is just suitable in functions where rear brake drums are used. When the parking or emergency brake actuator lever goes over a particular amount of travel, the ratchet advances an adjuster screw and the brake shoes move toward the drum.
Placed at the base of the drum sits the manual adjustment knob. It could be tweaked using the hole on the other side of the wheel. You will have to go beneath the vehicle with a flathead screwdriver. It is extremely vital to adjust each and every wheel evenly and to be able to move the click wheel properly for the reason that an uneven adjustment could pull the vehicle one side during heavy braking. The most effective way to be able to make certain this tiresome job is completed safely is to either lift each wheel off the ground and spin it manually while measuring how much force it takes and feeling if the shoes are dragging, or give everyeach and every one the same amount of clicks using the hand and then do a road test.
