    Hi everyone, sorry for the delay in getting back. This is good news and I'm feeling optimistic that I got the extent of the wear on my rear hub wrong. The bike is not here but she'll be back soon and I'll get back in and look again

    Are there any replacement shoes that do wear instead of the drum? One's that are softer.

    Yes and no. Pretty much all the aftermarket friction material is softer (as it should be), but all the aftermarket shoes seem to use the same defective castings that don't fit right. They can be cleaned up with a file to work, but for the amount of trouble involved it's probably easier to just have your oem shoes fitted with new pad material.

    The only way I have seen it dome properly was sending your shoes to a brake/clutch relining place and have the stock shoes relined. Softer? From what I have seen, ANY shoe lining is a lot softer and works a LOT better from the reports I have got.

    I have a drum brake that needs some work. Is the shoe material that Bench Mark Works sells something that will not wear the drum as quickly? The pad thickness on my shoes is about the same as what they have.

    Anyone get anywhere with the plasma coating?:ear

    I've contacted a company (Plasma Coatings Arlington, TN) which does plasma coating and will report back when I hear something. I'm not sure if the drum will have to be turned....if so that will create another issue. I'm guessing it will need to be done. I have two rear wheels. I haven't measured the ID but pretty sure one is worn past the limit. I need to measure them both.


    Hub spec is- Min- 200mm
    Max- 201.5mm

    The hubs I have measure 201.676mm ( 124K miles)
    . 200.406mm (miles n/a)

    I'm currently working on a friend's G/S that has a set of freshly relined oem shoes. They do not conform that well to the drum. We will do a short break-in ride then pull the shoes and sand the high spots, just need to be careful not to overheat and glaze the lining.

    Two questions in my mind:

    Is the Midwest company referred to Millenium Technologies by any chance? They have always been one of the top rated outfits for recoating Nikasil cylinders.

    Does anyone know if a process I've known as sub-arc welding is suitable for building up the steel lining in the drum? I saw it used on the prop shafts (Monel) of my CG patrol boat in Runyans Shipyard in Pensacola back in the 80s. Due to electrolosys the shafts had sections that had to have several inches diameter turned down on a (very big) lathe. Then the sub-arc machine deposited new metal layer by layer as the lathe turned the shaft at about 1-2rpm. I'm not sure how much heat was generated and transferred to the shaft itself, but one of the shipyard supervisors made it sound pretty low with no visible arc going on.
