Rules aren't a substitute for common sense. If it looks bad and seems bad - it probably is bad. Meet coordinators may require additional equipment for certain runs. Motorcars not so equipped will not be allowed to run at these excursions. Cars will be inspected for defects at excursions.
Proper maintenance is also the owner's responsibility.
Application and release of the brakes must require one simple direct motion by the operator. The brake lever must not be against the stop when brakes are fully applied. Brake end arms shall not be in danger of going over center with full application. Electric brakes will not be allowed on motorcars or trailer cars. Non-OEM brakes boosted or operated from engine power or air pressure will not be allowed.
