> The 1100 track brakes would always slap on hard just before complete stop.

Those jerky stops were mostly the drum brake actuators coming on because they were all or nothing, instantly. It also had to do with the Muni using higher friction brake linings for the SF hills than were used in relatively flat St. Louis.

> The San Francisco original cars did not jerk to a stop like that. As I recall the double ended cars stopped the smoothest.

Different type of drum brake actuator and actuator control system, which were designed to avoid this. The double-enders and 1016-1040 all have the same drum brake system.

> 1100's had GE motors and controls as I recall.

GE control and GE 1220 motors.

> The others were Westinghouse 1432?

1016-1040, yes.

> I am not sure abut the double-ended.

Same as the 1100s. However, any double-ender which has been rebuilt by Brookville now has Westinghouse control (has to do with replacement parts availability).
