BN2 Brakes

My my 1956 Austin Healey, BN2, has been sitting for over a year, but now finally decided to fix my brakes. I had problem with handbrake locking up, so I cleaned the shoe slide up so they now slide easily, which seemed to fix hand brake problem. Now the left rear wheel will not release when I apply the foot brake. My thought is to get a new left rear slave wheel cylinder.

Any thoughts about this one wheel locking up? All worked well for most part for last 14 years. Thanks Marty

Had the same problem with my 56 BN2 but with both right front and back cylinders so worked on replacing the slave cylinders. Unfortunately, I went through multiple cylinders from Moss and others before I found ONE that wouldn't badly leak. Very poor workmanship with uneven cylinder walls. I finally got the rear brake working with the one good cylinder but gave up and installed a disc brake kit from AH Spares in the front (very good product.). Given the hit-or-miss on the new cylinders, maybe try lightly honing out the existing cylinder first.

Be aware: At one time, at least, cylinders for one side were much more expensive--I think it's the right, but not sure--and we ordered one only to find it had obviously been used. Apparently, someone had bought one, and returned their used one for a refund. I know for a fact [insert well-known supplier name], for one, does not inspect the products they put back on the shelf.

Thanks Mike. Friend just thought brake hose could be collapsing but when I looked one hose went to both wheels. 6 years ago I replaced that hose with top of line colbalt hose. My problem is only with left wheel so it would have to be both for that. So like you I think it can only be left wheel cylinder.
