Abstract: A hydraulic brake assembly comprising a fluid conduit containing hydraulic fluid, a cylinder having a port fluidly connected to the conduit, and a piston positioned in the cylinder. The piston includes a recess having a depth at least 30% of a length of the piston. The assembly further includes a rod having an inner end positioned in the recess and an outer end outside the recess. In one embodiment, the piston moves relative to the cylinder along an axis, and the piston further includes a primary piston seal and a secondary piston seal separated by a seal spacing. The rod can axially overlap the secondary piston seal. For example, the inner end of the rod can be positioned axially between the primary piston seal and the secondary piston seal, and is preferably axially closer to the primary seal than to the secondary seal.
