Cessna singles don't have good park brakes. However, I'm thinking of another reason why not to use them. Our instructors tell students never to use them, for a long time I didn't know why. Because it's in the POH, I started doing it sometimes when the apron was not level for example.
One day I was taxiing for takeoff and noticed a steering problem. the aircraft did not turn right anymore with full rudder applied. I aborted takeoff, shut down the aircraft with 1 wing still on the rwy...Manually pushing the aircraft was not possible. 5 minutes later the mechanics came and pushed the aircraft back without a problem...
Seemed that 1 brake was still applied, a good knock on it with a mechanics boot and it let loose. And when I told our instructor what I experienced he told that was the reason why his students may not apply PB. He told a solo student had also had a dragging brake, didn't notice it and took off. During that takeoff the brake overheated and got on fire.
