Dual Discs

[DgM]

Thanks for your assistance.  Christmas came in July.  Picked up complete R65LS hydraulic - master cylinder to calipers - with brackets etc.  However, I could use some clarification on the bushings used to mount Brembos to fork leg.  I've seen ATE calipers with mounting holes that match bolt diameter.  The mounting holes on my Brembo are larger than the bolts, and on the schematic gracefully posted there are parts #4 and #12 that seem to be the bushings needed.  Anyone have the parts numbers for the bushings?  Are they top hat section or cylindrical?

The bushings are top-hat shaped - unfortunately I don't have access to my photos right now - I think that they can still be ordered, though someone may have an alternate (And cheaper) source to use for them.

Those bushings, called 'sleeves' in the parts catalog, to complicate matters, are available in different thicknesses in the flat flange area.

I think this is to get the caliper 'centered' over the rotor.

I don't know how critical this is, as the left caliper does not have the bushings or 'sleeves' installed, at least on my '81 with dual ATE calipers.

Thanks for info.  Will have to wait to mount disc on wheel, then position caliper to determine centering over disc.  Scientific.

I can't tell from your profile, as to where you reside, but if you are in the US , or somewhere that uses the non-metric system, the sizes shown in the parts catalog under the supplement category like : 1,2  2,35  3,5 are the thickness of the flange area in millimeters,  3,5 would be 3.5 mm.

These parts catalogs take a little getting used to if you are not familiar how to use them.
