Narrative:

After landing on runway 26 and slowing to a normal speed (I estimate less than 5 mph) to depart the runway; I started the 90 degree right turn for A2. The aircraft did not seem to be responding as normal to pedal input; so I also applied toe brakes. The aircraft still did not seem to be responding normally to the inputs. The aircraft did turn and slow; but it became clear the aircraft would go over the edge of A2; which it did. I applied both toe brakes to bring the aircraft to a stop; but they did not seem to [be] very effective; so I pulled on the hand brake; and the aircraft stopped beyond the hold line/clear of the runway; on the grass next to A2. The aircraft stopped about 10 feet in front of a taxi light and about 20 feet in front of a sign. The aircraft was sitting on the grass with normal propeller clearance; level; etc. I understand this was not an accident or incident. I informed tower and asked tower to notify the FBO that maintains the aircraft to arrange a tow. I then shut down the aircraft and used a hand held aviation radio to communicate with tower. I did not want to taxi the aircraft because I did not know if there was a mechanical problem; or not. The airport manager was very helpful and removed the taxi light (mentioned above) to make it easier to tow the aircraft. He was also very courteous and generally helpful. I have contacted an instructor for a session in this aircraft when it is returned to service; and before any further flying.
