Ha! I had an '84 Mustang GT. How did performance cars from that period NOT have 4 wheel disc brakes? The rears were still drum brakes! Which leads to a rather humorous yarn from my storied youth:
The 1984 charcoal gray Mustang GT with T-Tops was the first car I purchased. It was sleek, shiny, perhaps a bit too fast for my age, and the insurance premiums cost more than the car payment. It was also the least mechanically sound vehicle to hit the road...ever. I learned everything I know about car repair from my 4 year love/hate affair with this Mustang.
In the summer of 1987, it was time for a brake job. I had never changed brakes before, so I purchased the equivalent of a YouTube guide at the time...a "Chilton Manual"...and proceed to muddle my way through fuzzy black and white pictures and poorly worded instructions.
My neighbor, a notorious red-neck chain smoker, walked up when he saw me struggling to get the rear brake cover off of the rusted drum assembly. He showed me how to take a hammer and pound on edges until the cover came loose. I pounded away, and the cover fell to the ground---creating a mushroom cloud of black brake dust. The dust covered my clothes, face, hair...everything.
My neighbor takes a huge puff of his cigarette, blows the smoke out the side of his lips, and then gives me the sage advice: "By the way...don't breathe that stuff. It causes cancer."
