Well I'm stockpiling TSMs, for now 60 - 79, later I'll do 80 up, and making a Grand Unified Brake Specification spreadsheet. Does anyone have AMC factory spec data on 1970 brakes? The TSM is surprisingly silent -- it doesn't list show width, caliper bore, or wheel cyl diameters! Weird. I can get it online I suppose from aftermarket sources, but it would be nice to know where AMC brake data isa. Does that year have a separate brake supplement? Here's one for you: 1975-up brake "combo valve": * auto-resets the warning switch after bleed or repair * contains rear-brake pressure hold-off (stem on the end) eg. proportional valve. It can be identified by the little pull-out spring loaded stem on the left end. Does that last mean you don't need the check valve in the master cylinder port for the rear brakes? Here's another one: * Many cars have different drum shoe *widths* in the same wheel -- I thought it was a typo at first but it's consistent across many years. (Leading shoe narrow.) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
