That was another owners car, I'll have to check with him, but I am sure his has the new style e-brake. It makes little sense to me that IF the rear brakes were problematic that the front ones wouldn't lock up on hard braking...the physics of brakes. Since there is no apparent lock up at any time, I suspect a low vacuum signal. I have yet to see any brake system where one side is non functioning( frozen even) that wouldn't create a lock up on the other side(or end).

Half of the cars that leave our shop have belt driven vacuum pumps installed on them (SPF or otherwise). As far as Roush engines go, we use mostly the SR versions with the TW cam. They produce more vacuum than the R versions. I have not had a problem with the rear calipers in any of their incarnations. The driveshaft e-brake is the only thing that gives us troubles; mostly from customers leaving them on. We are working on a few e-brake improvements. One uses two calipers on the rear rotors, the other uses the Explorer style drum in the rotor. After more R&D I will post some pics.
