[DML] Low Drag Disc Brakes

[Bob Brandys <BobB@xxxxxxxxxxxxxx>]

In the early 80s, cars shifted to low drag disc brakes.

For example, the 82-83 AMC Spirit disc brakes were low friction 
compared to the 78-79 Pacer disc brake pistons. The parts are 
interchangable so you can upgrade a Pacer to the low friction pistons.

What about the D?  Are these low friction disc brakes?

Are there later model calipers that are low friction.

Typically, the low friction pistons slightly retract after application. 
  This could be a spring in the main piston that creates a  little 
negative hydraulic pressure to retract the pistons.

Drum brakes used to do this with springs.
