3 DANR O DOUBL CLAMP BANDD SPRIN BRAKS INDUSTRY SATY RMINDR: Combination Piggyback Plus Kit Before 1989 double diaphragm spring brake actuators were manufactured using two clamp bands; one to seal the service side and one to seal the spring parking side. At VMRS# one time both sides of these units were considered serviceable, VMRS# meaning that if either side failed the clamp band could be removed, the diaphragm or other components could be replaced, and the unit continued in service as repaired. DOUBL DIAPHRAM - STANDARD STROK While removing the clamp band on the service side of a double diaphragm spring brake actuator carries little or no risk, experience showed that all too often technicians did not follow the required safety procedures when removing the clamp band on the spring parking side, resulting in a potential for severe personal injury. If the powerful spring in the spring parking side is not properly caged before the clamp band is removed the spring can propel components of the assembly with great force, potentially causing severe personal injury. MODLS In response to this safety problem MM Brakes pioneered the development in 1987 of the Tamper Resistant double diaphragm spring brake actuator with the first non-serviceable spring parking side. By the early 1990 s the entire domestic industry recognized the enhancement to safety offered by the Tamper Resistant design. Today every responsible spring brake manufacturer based in the United States offers only spring brakes utilizing a Tamper Resistant technology. As a result of the universal adoption of a Tamper Resistant design for the spring parking side of double diaphragm spring brake actuators, instances of injury to workers from improper repair procedures or accidents have steadily declined until today they are virtually nonexistent. Unfortunately, a disturbing trend is emerging within the aftermarket portion of the heavy duty truck industry - the use of double clamp banded spring brake actuators as replacements for damaged or failed Tamper Resistant units. This reintroduction of double clamp banded spring brakes into the North American market seriously threatens worker safety in the heavy duty truck industry. specially at risk are those workers least experienced in the industry. Well over a decade has passed since MM Brakes introduction of Tamper Resistant spring parking brakes and many in the service and maintenance end of the industry have not seen, let alone serviced, a double clamp banded spring brake. Younger workers are not likely to have been trained in the special safety procedures required to cage the spring before servicing the spring parking side of double clamp banded units. Therefore, MM Brakes believes the industry needs to be reminded of the dangers associated with servicing double clamp banded spring brakes.
