There's not much good to be said about the rusty old drum setup on the car. At the time of its introduction, the hydraulic setup was a significant improvement over the old mechanical systems. But the single-reservoir master cylinder was an accident waiting to happen. One leak or failure anywhere in the system, and you had no brakes, front or rear. In our case, a mechanical adjuster came loose on one wheel, and that was enough to make us lose our brakes completely.
