Rebuilding a Classic Mini brake wheel cylinder

[@TornadoCAN99]

I need to do this on my newly purchases MkV 1988 Mini. Are there different cylinder kits to figure out? Also, a good tip for Ultrasonic cleaners....no need to fill the tub with degreaser/cleaner. Just use water. Then place parts in a hard plastic/glass jar or even a zip lock baggie and put a much smaller amount of your cleaner solution in the container. Then put the container in the water and let her rip.....cleans just as well since the sonic pulses penetrate into the container just fine. Saves having to keep large volumes of potentially smelly cleaner and reduces waste build up.
