This is off the topic a bit. When growing up my father owned a 1937 Rolls Royce. It had mechanical brakes but had a servo clutch on the transmission. As you pushed the brake pedal the rear brakes would come on. As you pushed harder the servo clutch would engage and pull the cables for the front and rear brakes. This worked like power brakes. But, if the rear wheels started to skid, the servo force would be reduced, thereby reducing the braking effort. It was an automatic skid control. Modern cars have this but it is controlled by a computer and sensors at all four wheel.

The brakes saved by father from an accident when a school bus pulled out in front of him.

Forget the brakes, they really don't work. The clutch always sticks, and starts with a jerk. My car grows red hair, and flies through the air. Driving's a blast, a blast from the past.
