From the other threads I have read, it appears my A-60 actuator is functioning correctly. However, I was bleeding the brakes for the first time (new to me trailer) and couldn't find the screwdriver slot. So, I used a strap to compress the actuator. I then had to use a block of wood and a big hammer to drive it back out so I could compress it again. Should the actuator be that hard to pull out or should I be able to do it be hand?
