Summary
The pilot reported that the aircraft brakes were serviceable prior to DEPARTURE. However, when braking was attempted during the landing roll there was no reaction, and no pressure was felt through the brake handle. The aircraft overran the end of the strip and collided with a fence. The brake master cylinder valve seal had failed, allowing the piston to extend further into the cylinder than normal. The piston had in turn become jammed by corrosion products.
