My 1963 Holden has drum brakes all round. The fronts had always been a problem pulling and shuddering. I have had the drums machined and fitted new shoes and adjusted them up correctly. The shoes are the correct fit in the machined drums.
They are now working really well when cold. Once they heat up I am getting a bit of shudder, nowhere as bad as before but still annoying. No longer pulling to any great extent. My question is, why would the shudder only happen after driving for a while and the brakes warm up?
