Why Does the Forklift Have No Brakes?
2 Answers
Forklifts losing braking functionality is primarily caused by lack of maintenance and improper operation. The braking system lacks necessary upkeep, leading to excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, contaminated brake fluid or mixed brake fluids causing vapor lock when heated, leakage in the brake master or wheel cylinders, and air leaks in the air reservoir or pipeline connections. Improper operation can cause mechanical failures, such as downhill driving generating friction heat on brake pads, carbonization of brake drums, and complete loss of braking function. Function of Service Brakes: During driving, service brakes (foot brakes) are commonly used to decelerate the vehicle or bring it to a stop within the shortest distance possible; they also help maintain stable speed when driving downhill. Function of Parking Brakes: Parking brakes not only keep the vehicle stationary but can also serve as an alternative if the service brakes fail. Once the vehicle is parked, the parking brake (hand brake) should be engaged to prevent the vehicle from sliding forward or rolling backward.
A forklift without brakes is no small matter. Last time I operated a loader, I experienced this and it scared me so much my back was soaked in sweat. Brake failure is 80% likely due to hydraulic oil issues—maybe an oil leak in the lines or air in the brake pump. It could also be that the brake pads are worn down to the metal, especially if you've been slamming on the brakes repeatedly while reversing to scoop material. Try pressing the brake pedal—does it feel spongy? If so, stop immediately and check the fluid level in the reservoir. Remember, a forklift weighs several tons—never force it to move without brakes. Shut off the engine, engage the parking brake, and call a mechanic to handle it safely.
