The J-Series Piston brake chamber is the ultimate product to minimize down time due to not having a diaphragm that can fail on the parking brake side. It is designed for use in demanding parking and vehicle holding situations. The power spring output force of a type 30 J-Series is 900+ pounds greater than a type 36 diaphragm chamber. The piston brake is the preferred brake on Emergency vehicles, Transit, and any fleet that wants to minimize the amount of road calls they have.
