I recently completely restored the original brake system on my 1931 Cabriolet. Everything redone; new cast iron drums (Mel Gross), new shoes with bonded linings arc'd to drums, new rollers (+ all misc moving brake parts, adjusters, etc.), new front floaters, all slop taken out of all linkages, re-bushed bronze main brake cross member. Also restored the entire front end together with a rebuilt steering box. ($$$s) Front wishbone ball & kingpins are good.
Everything is great (both brakes and steering) EXCEPT that when coming to a short stop with the brakes at the end of either a tight right or left turn (like when maneuvering in a parking lot), the brakes make a loud groaning noise until motion stops.

No such noise at any other time.
Any ideas? I was told that it may be from the front floaters...
