discs

[Don Dulmage <big-d@xxxxxxxxxxxx>]

I remember when discs first came . here where it snows everybody hated them The front wheel would lock up in a snow covered road stop and we would slide with no steering. Now they have antilock which keep the wheels from locking since we have learned that there is such a thing as too much braking as well. New cars have reduced rear brake sizes to laughable  in fact I think they might as well chuck them as they are about useless. So we reduce beaking ower with antilocks so it doesnt skid etcetc. Sort of like wearing high heels and bending down at every door way. A good well set up set of metallic linings work well. It may not be what everyone wants but they cetainly are not unsafe.  Sometimes  and more often than not the disc kits are crap and work worse than the original drums. Especially the ones for A bodys usung GM truck parts. some that i have worked with for customers have had the wrong sze master and not worked well. We wre able to cure it with a Cuda Challenger master intalation.One new kit i saw siezed when hot.  We had to change thecalipher to a different style fo piston (aluminum instead of pheneolic.)
Drum brakes of the bendix design (63 and later Mopars) are self engergizing , something disc brakes dont have. Biggest advantage of discs is the ability to get rid of heat. In a road racing situation there is no question they are neceassary as brakes can run red hot. but for the occasionally driven street machine or even the one stop only drag cars in the 12s or 11s i dont feel they are necessary. Discs are also slower because they drag all the time. I have seen claims of 2 tenths. I have four friends who have had airheart disc failures on their race cars and gone of the end of the track two of these cars were converted to this half baked set up where YOU glue the pucks to the pistons. I think if I was to convert a B body i would search out a 69 to 72 B body and swap all the parts direct. Otherwise I do not like these mickey mouse made up half you know what combos that only bleed money from my friends wallets and dont work right. I HATE stuff that doesnt work "with a passion."
