Synopsis
Two pilots in a Cessna 210 reported loss of directional control after landing that resulted in a runway excursion.
Narrative
Came in for a normal landing to runway XX at ZZZ; night but VMC; landing lights were on for airplane and lights at the field were on. Touched down at normal speed and at about the 1000' mark on the runway and began slowing down by raising flaps; pulling back slightly on yoke to put more pressure on main tires; and applying pressure on brakes. Noticed at 1500-1000' remaining mark that aircraft was not slowing appropriately and applied harder brake pressure; at that time aircraft began/was veering to the left of the runway; and no pressure on right brake. I called for copilot to apply brakes also; he stated full forward on brakes; but right brake did not have any pressure. Aircraft departed runway between taxi lights and cut corner to taxiway where it came to a stop. Besides tracks through grass aircraft did not hit anything and did not have any damage. Attempted to taxi back to hangar but steering was ineffective without right brake and shut aircraft down on the taxiway to move manually back to hangar. Problem appears to be a failure of the right brake. On startup and initial taxi brakes were sufficient to hold aircraft during runup and to taxi around field. Unsure of cause of failure. Contacted mechanic to inspect and repair right brake and will not fly until the problem is diagnosed and fixed.
Second reporter narrative
Upon landing in a Cessna 210; the aircraft was not slowing down as we were reaching the end of the runway. The plane started to veer hard to the left. The pilot flying told me since I am another pilot to hop on the brakes as well. The left brake was working but the right was not; and since we were still at 40 knots and not slowing down quickly the brakes were locking up. As I went to push the brake pedals; my left foot hit the brake quickly and my right foot went almost to the floor. We turned hard left and went off the runway into the grass. No lights or signs were hit; but some tire marks were left in the grass. eventually got it back on to the taxi way and shut down.
