In reviewing my GMC brake system, I have discovered that my GMC includes an additional vacum booster unit mounted on the front line of the master cylinder going down to the equalizer valve. It gets its vacum from the normal vacum to the other booster on the master cylinder and from a reservoir built into the square frame system that was built under the front end for helping in the lifting and jacking of the front end. As I am seeing some loss of fluid from the front MC reservoir I may need some new parts for this unit. Has any one seen one of these and know where one could find parts. Picture of unit is located at: http://www.gmcmhphotos.com/photos/data/500/medium/P10100037.JPG
