One problem related to power assist brake has been reported for the 2001 Dodge RAM. The most recently reported issues are listed below.
Two times while backing out of my garage my power steering and brakes went out. The first time resulted in a power steering fluid leakage. After ten minutes the truck was able to be driven to the dealer where the power steering pump was replaced. The second time I was also backing out of my garage and lost both the power steering and power brakes. This time the manufacturer had to have the truck hauled to the dealer. The power steering pump was replaced. Dealer told me that the brakes and steering are run off the same gearing on the front of the engine. This truck seems to require constant correction to the steering to minimize wander.
