A spring applied, hydraulically released brake includes a housing 12 having an open end adapted to align with a vehicle surface and an internal ring 32 extending from an inner perimeter of the housing. The brake comprises a disc stack 20 including a thicker stationary disc 50 having a tab with a hole therethrough, the hole receiving a slotted spring pin (90, fig 3), the pin (90) slidably receiving a pin spring (92) over a portion thereof. A spring assembly 18 urges a piston 16 into contact with the disc 50 to establish a default position of the brake where, in a released position of the brake, the piston is not in contact with the disc 50, and the spring (92) urges the disc 50 into contact with the internal ring 32 to thereby prevent the disc 50 from free floating. An open-ended brake reduces the length of a storage package and can reduce cost. Upon failure of the hydraulics, the pin spring (92) releases the brake so that a vehicle (e.g., a tractor) may be towed.
