Aircraft
I am the pilot/owner of Pitts S1S; Aircraft X. Upon returning to ZZZ from a short VFR pleasure flight; I was cleared for a visual approach to Runway XXL at ZZZ. The approach and landing were normal. However; immediately after touchdown; the right main tire chattered and squealed as if the brake was locked up. The aircraft began pulling hard to the right and I countered with left rudder input in an attempt to maintain directional control of the aircraft. To no avail; the aircraft continued right and as it slowed it began a clockwise ground loop. The right main tire lifted off the ground and the left wingtip and outboard side of the left aileron scrapped the ground as the aircraft came to a stop with the tail wheel about three feet off the runway and the nose pointing southbound.Tower radioed me regarding my status and I told them I was OK and will attempt to taxi the aircraft clear of the runway. I taxied the aircraft a very short distance onto taxiway; shutdown and secured the aircraft systems. I egressed the aircraft and inspected the airplane. The right main tire was flat and the tail wheel assembly was damaged and bent from the side load during the ground loop. I was not injured during this event. Subsequently; ZZZ aircraft operations met me and we proceeded to transport the aircraft back to my hanger after talking to FAA and NTSB personnel which the Tower had contacted.
Pitts pilot reported indications of a main wheel brake locking up on landing; causing a ground loop.
