[Frank Miller]

To those who do not know, floaters basically keep the brake shoes centered with the drum at all times. The rest of the system must be in good condition as any slop gives you excessive pedal travel.

As far as wheels locking up, it may not be desirable but it tells you that the tires are now the weak link in your system. All the hydraulics in the world will not stop you faster. Adjustment and modulation will ensure optimum control while braking.
