Forklift Brakes - A brake wherein the friction is supplied by a set of brake pads or brake shoes which press against a rotating drum shaped unit referred to as a brake drum. There are a few particular differences among brake drum types. A "brake drum" is commonly the explanation provided whenever shoes press on the inner exterior of the drum. A "clasp brake" is the term used so as to describe when shoes press against the exterior of the drum. Another kind of brake, referred to as a "band brake" utilizes a flexible band or belt to wrap round the exterior of the drum. Where the drum is pinched in between two shoes, it could be known as a "pinch brake drum." Like a conventional disc brake, these types of brakes are somewhat rare.
Old brake drums, prior to the year 1995, needed to be consistently adjusted so as to compensate for wear of the drum and shoe. "Low pedal" could cause the needed adjustments are not carried out satisfactorily. The vehicle can become dangerous and the brakes could become ineffective whenever low pedal is mixed with brake fade.
There are several different Self-Adjusting systems for braking available nowadays. They could be classed into two separate categories, the RAD and RAI. RAI systems are built-in systems which help the tool recover from overheating. The most recognized RAI makers are Lucas, Bosch, AP and Bendix. The most famous RAD systems consist of Ford recovery systems, Volkswagen, VAG, AP and Bendix.
The self adjusting brake would usually just engage if the vehicle is reversing into a stop. This method of stopping is acceptable for use where all wheels utilize brake drums. Disc brakes are utilized on the front wheels of motor vehicles today. By working only in reverse it is less probable that the brakes would be adjusted while hot and the brake drums are expanded. If adjusted while hot, "dragging brakes" can take place, which raises fuel intake and accelerates wear. A ratchet tool which becomes engaged as the hand brake is set is another way the self repositioning brakes can operate. This means is only appropriate in functions where rear brake drums are utilized. Whenever the emergency or parking brake actuator lever goes over a certain amount of travel, the ratchet improvements an adjuster screw and the brake shoes move toward the drum.
Located at the bottom of the drum sits the manual adjustment knob. It can be tweaked making use of the hole on the other side of the wheel. You would have to go underneath the vehicle with a flathead screwdriver. It is extremely important to adjust every wheel equally and to be able to move the click wheel properly in view of the fact that an uneven adjustment may pull the vehicle one side during heavy braking. The most efficient way so as to ensure this tiresome task is completed safely is to either lift each and every wheel off the ground and hand spin it while measuring how much force it takes and feeling if the shoes are dragging, or give each one the same amount of manual clicks and then perform a road test.
