ABS Electric Power Brakes - some clarification to clear up the confusion.

When we showed you ABS Electric Power Brakes in a recent issue of Mustang Monthly, we weren't clear enough on some aspects of the system. We're here to set the record straight per Mike Peterman of ABS Power Brakes.

1: The ABS Electric Power Brake System consists of a master cylinder with integrated power booster and electric hydraulic power supply (pump). Bonus here is function along with space.

2: The unit does not have a proportioning valve nor does it have a hydraulic brake light switch. It works with existing proportioning valves.

3: The relay we mentioned turns the system on and off with the vehicle so there's never a chance of it running when the ignition is off. The pump runs only when the system needs pressure, which happens via the pressure switch. 

4: The pump runs only when braking system pressure is needed. When brake system pressure drops to a pre-determined point, the pressure switch closes and the pump comes on. A brake system accumulator maintains pressure when the pump is off. Mike tells us the pump comes on every 8-10 applications of the brake pedal.

5: The round pressure accumulator maintains brake system pressure made by the pump, which allows smooth, powerful brake application. It must be plumbed between the electric pump and the master cylinder inlet. It can be located just about anywhere, Mike tells us. 

6: The control switch (also called a pressure switch) closes at a predetermined pressure, turning the pump on a bringing the system back up to full operating pressure - again good for 8-10 applications before it closes again.

7: The relay closes and provides electric power when the ignition switch is turned on. It is open when the ignition switch is turned off according to Mike.

8: The lever adaptor shown at the master cylinder rod is there to give the ABS system on Mustangs with manual brakes a true power brake feel. Mike tells us, "I move the connection point down to where a power brake connection should be 4:1 pedal ratio. A 6:1 ratio would be too touchy."
