Interesting information. I appreciate it. Drivers are very aggressive in this city. Our insurance rates are through the roof. People accelerate as fast as they can without squealing away from stops and will accept a spacing of more than two vehicle lengths at expressway speeds as an invitation to move in front of you. Even as traffic is slowing down. Yes drum brakes are usually as effective as disks until they heat up. But these people don't need much driver skill when all they have to do is to place steady pressure on the pedal and let the anti-lock system take over. Traffic in this city travels very fast between stops during rush hour and people make all sorts of crazy lane changes, even though they don't get anywhere any more quickly. I have no scientific proof of the following, but I suspect that the one hundred to one hundred ten degree afternoon ambient temperatures we have nearly half the year, the intense sunlight shining on the extensive expanse of asphalt, etc. combine to provide an environment non condusive to brake cooling. My Imperial, with its Budd disk set up stops very well in most instances. It isn't on the road at the moment. The Full Contact brakes on the '59 Plymouth were hard to keep in adjustment, but worked okay. They did fade fast in stop and go traffic and when I took my foot off the gas to coast a little bit within a block of a red traffic signal, I would often encounter somebody cutting in front of me at the last minute and forcing me to stop more suddenly. The AAJ brake disk conversion has shortened the stopping distance and the brakes do not heat up as much in heavy traffic, making the stopping more predictable under all circumstances. Incidently, the Plymouth also has radials and gas shocks. The Imperial has radials, but still has hydraulic shocks. I do use the breaker cam lubricant and had the Plymouth's original Autolite distributor rebuilt by a very reputable restoration place. All new bushings, etc. Also new correct ballast resistor, new cap, rotor, etc. I could not keep a set of points in there. It was very frustrating since the car is driven almost daily. Couldn't find the problem, have been installing points in various vehicles for more than half my life and never encountered this before, so I gave up and went electronic. :-) I wish I knew about that suspension swap when I had my '68 C-20. I'll keep it in mind for my '66 C-10. K.
