If the brake light is on then for sure there is a problem, the vacuum pumps are known to fail on Diesels, so that would be a place to start, if the booster is not getting any vacuum then you will almost have the stand on the brakes with both feet to get it too stop, a simple vacuum tester hooked to,the brake booster will tell if you are getting enough vacuum to make the booster work.
