Abstract
A tractor vehicle transmission is provided with a two piston brake where each piston operates in opposite directions. A gear is located adjacent the brake which is located in proximity to a wall of the transmission. Thus upon actuation the brake wall contact the gear causing retardation of the gear, its attendant shaft, and the transmission as a whole allowing simpler shifting of the transmission. The piston force against the brake is opposed by a second piston having a spacer means that contacts the transmission wall upon actuation.
