660 Actuator

[zelmo]

I know that when you store a trailer with the A-60 actuator you should chock the wheels and pull forward so that the cylinder is in the correct position. I can’t find this issue in the manual for the 660 and drum brakes. Does it work the same way?

Mine A60 doesn’t, once I unhook it is freewheeling

It isn't to make the wheels freewheeling, it is to prevent rust:

The reason for pulling forward is to allow the piston in the master cylinder to return to zero, against the snap ring. This protects the honed cylinder and keeps it from rusting. A rusted cylinder will subject you to hot brakes situation by not releasing the piston all the way and allowing the fluid to return to the reservoir.

Before you back the trailer in place install the lock out tab and put a speaker magnet over it to keep it in place. This keeps the actuator extended. Disconnect the trailer and remove the magnet/lock out tab. No chocking.

Instead of messing with the lockout tab I put a lockout cap on my A-60.



I am still looking for an answer on the 660 actuator. Does that need the same attention?
