Does anyone know the minimum acceptable diameter for a '67 SIIa 2.25? I am getting excessive pedal travel. At first I thought this was air in the lines, so I did a thorough bleeding, and still the pedal goes almost to the floor before engaging the brakes. I confirmed that the bleeding was successful by clamping the three rubber lines (I know, bad move) and the pedal was hard as a rock.
I was able to adjust the shoes, but not on all the wheels (some wheels the adjusters kept spinning and the shoe never contacted the drum). Drums look to be original. I am in the process of installing new shoes.
Anyway, I wanted to see if I should buy all new drums, but thought it would make sense to measure the existing drums before dropping the money.
The internal diameter of one drum I measured tonight was 10 3/8 inch across (from wear surface to wear surface). I believe the RN brake tutorial in the technical library states anything over 10 1/16 inch diameter should be replaced.
THANK YOU!
