It's turning out to be nearly impossible to generalize what brakes are likely to turn up on which cars. It's true that heavier models like 77 wagons got bigger brakes, but sometimes the opposite is true -- the 1980 TSM states that 4-cylinder Concords got rear 10x1.75 brakes yet 6-cylinder Concords got 9x2's. It's not a typo. All I can figure is that due to the lighter engine, front-rear weight transfer issues means the rears are doing more work on the 4-cyl car. It may not be 'figurable' post facto since we don't now know what the factory was tuning for. And three different front rotor diameters that year? Must mean there are three different size caliper brackets or three different calipers. Weird. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
