brake roller tracks.

[Lawrie]

Im doing some minor brake repairs on my 34 coupe,
I noticed while away, some times the rear brakes dragged on after letting off the pedal.
Found the roller tracks in the back had a groove from the roller pin in them, and the shaft bushes were worn.
my fix was to grind them flat again,( .019 in) off the face, then make over size heads on the pins to take this up.
the shaft was also loose in the bushes so tomorrow will fit the new bushes and make new pins with the larger head to suit.( hardened)
I had tried welding the roller tracks up on my model a but it was always a pain getting them flat again,I think this is a far nicer fix for me.

Nice setup, I hadn't thought to put a dremel stone in a milling machine. This is one of those cases where the cleverness of early V8 enthusiasts outside the USA shows, here I would just find a better backing plate. The mechanical brake baking plates have been worth so little here since the Bendix style hydraulic brake setups came to market that I have been given two restored cars worth of complete mechanical brakes setups plus some spares.
