PA28 ??????????
There are an number of fits an variants of the PA28-140 that make some of the comments above invalid for one aircraft or another so talk of brakes and trim can only be confirmed by inspecting the aircraft.
If the aircraft is left outside take a very good look at any place that steel and alloy fittings meet.
I would add there are a shed load of dogs about that will eat money faster than an Essex girl in west end night club.......... And one or two gems but sorting them requires the employment of an engineer who has worked the type for the last twenty years if not more.
