Narrative:

Went out for a few takeoffs and landings and remained in the traffic pattern. The first takeoff and landing was normal as was the second takeoff. On landing when I went to brake I found that the right main gear brake was not operating and consequently departed the runway to the left and then down into low area left of the overrun area. While off the hard surface I hit a couple of runway lights and incurred some repairable damage to the leading edge of the left wing. There were no injuries to myself or any ground personnel who came to my aid and towed my aircraft back to my hangar. I sealed a fuel leak on the leading edge of the left wing and put the airplane in the hangar. When I came back the following day to check on the damage I found a sizeable puddle of brake fluid below the right main gear and upon cursory inspection found that the bleeder valve on the brake had worked itself loose. Once again this is a fairly easy repair.

Title: An Experimental aircraft pilot reported a loss of right brake control during landing that resulted in a runway excursion and contact with several runway lights. Later; the right brake bleeder valve was found loose and leaking brake fluid.
