Most forklifts are equipped with hydraulic service brakes as their primary stopping system. These are typically either disc brakes or drum brakes activated by a foot pedal . In standard warehouse forklifts and smaller internal combustion models, the most common configuration is the drum and shoe brake, which uses friction between a rotating drum and stationary brake shoes to slow the vehicle .
The Two Main Brake Systems on Every Forklift
Regardless of the specific technology, every forklift is required by safety standards to have two distinct brake systems :
Service Brakes (Primary System)
The service brake is the foot pedal system you use to slow down and stop during normal daily operation. It is hydraulically activated, applying pressure to either disc or drum mechanisms to create friction .
Parking Brake (Secondary System)
The parking brake keeps the forklift stationary when parked. It is typically a mechanical system using a lever, cable, and hand brake assembly. On many electric forklifts, the parking brake is an electromagnetic (EM) brake that applies automatically when the motor stops .
The Most Common Types of Service Brakes
Drum brakes are the traditional standard, especially on internal combustion forklifts. They work by pressing brake shoes against the inside of a spinning drum. When properly maintained, brake shoes typically last 5,000 to 7,000 hours .
Disc brakes are becoming more common, particularly on newer electric and heavy-duty forklifts. They function similarly to car brakes: calipers squeeze a rotor attached to the wheel. They offer better heat dissipation than drum brakes .
Wet disc brakes, also called oil-cooled brakes, are sealed within the axle housing and bathed in oil. These are preferred in heavy-duty or extremely dirty environments because the system is protected from dust, debris, and corrosion. They rarely need replacement and only require periodic oil changes .
Specialized Brake Types for Different Forklifts
Electromagnetic brakes are common on electric forklifts. They are often used for parking and emergency braking. There are several subtypes, including electrically-released dynamic (ERD) brakes and load wheel brakes, which provide additional stopping force for trucks with high load capacities. Some advanced systems even use "variable torque" brakes that adjust braking force based on the weight and height of the load .
Regenerative braking is used in electric forklifts. It is technically an electric motor function rather than a friction brake. When the operator changes direction (known as "plugging"), the motor reverses and the kinetic energy is converted back into electricity, recharging the battery while slowing the truck .
Which Brake is Best for Your Forklift?
If your forklift operates in a dusty or dirty environment like a lumber yard, steel mill, or heavy recycling facility, wet disc brakes are the best choice because they are sealed from contamination . For standard indoor warehouse use on smooth floors, standard drum or dry disc brakes are usually sufficient and less expensive to maintain. For electric forklifts, regenerative braking should be a priority feature. It extends battery life and reduces wear on mechanical brake components.
