The Cessna 120-140 Association Forum

While going thru a cleaning of my airplane before installing the new interior, I found that one of the brackets that goes around one of the brake master cylinders that activates the parking brake function had fallen off ( or was taken off). When I mentioned this to a friend of mine who has a 170 he thought there was an AD or service letter about removing the parking brake. He said his 170 does not have a parking brake. I can't find anything about this anywhere.

Does anyone have any opinion or advice about this?

There is no AD and, as far as I know, no service bulletin for the 120/140. That said, the parking brake is more trouble than it's worth. I would disconnect and disable it before it leads to a ground loop or nose over. Just avoid parking on a slope.

Yes, I think that is good advice. Thats what my friend with the 170 said, he said he heard about the brakes getting activated in flight and then just what you mentioned happened on the next landing. Out it comes
