Re: [Amc-list] Small Yard Report (9" disc brakes???)

[Mark Price <markprice242@xxxxxxxxxxxx>]

I mentioned the small discs as being a possible good choce for easy bolt on light weight discs. It's been a few years back.
   To put it mildly I was told I was crazy and no such things existed..........

The six and V-8 cars used a 10.82" rotor, and I was under the impression that the 80-83 four cylinder cars used the same brakes (not the first time I've been wrong...). I know the 77-79 2.0L four cylinder cars used the same diameter rotor and the same caliper, but the rotor was solid, not ventilated. The pads had a thick spacer to make up the difference.

The only thing 80-83 TSMs list is thickness and run-out, no diameter. Makes sense, diameter doesn't change with wear! But I sure do like all the extra specs in the older TSMs.
