2 seperate systems. The booster would have to leak past its seal and then have enough presure to push through the master clys seals...unlikely. Have you had the truck to a quickey lube recently?? Maybe one of their techs Topped Off you fluids and put the wrong stuff on the wrong hole? Get out your reciepts and start looking. If you have the service done at a shop and then can prove that the damage was after their service you may be able to put in a claim. Good Luck... Chris
