im about to become the proud owner of a 1986 chevy K5 blazer. im a mopar type of person, so im not exactly familiar with gm trucks and such. what exactly is the purpose of the brake lines being in a coil coming out of the master cylinder on older gm trucks? im sure some of you know what im talking about..also, was the '86 blazer equipped with a solid front axle on the four wheel drive models?
