Intermittent brake lock up on 2007 GMC Savana 2500 cargo van. The pedal feels hard to push and the vehicle will not slow. More pressure applied to the brake pedal then the front brakes lock up completely. This happened twice at low speeds and once at freeway speed. Very fortunate that other drivers were able to avoid a truck skidding to a stop on the freeway. Turning the vehicle off for five minutes seems to allow the system to function again temporarily. Dealership reports "leaking hydroboost" unit is the problem. This is the second failure of this part in our 15 truck fleet, although the earlier failure did not cause brake lock-up.
