I have a '97 Ram 2500 6.7L diesel. My problem is that the steering and breaking has become harder over the past couple years. I am still getting 3 gal/pm flow and 1500 psi before the overflow turns on but it still just seems like it doesn't have enough power to easily turn the wheels and/or you have to practically stand on the brake peddle to stop. any info on the subject will be helpful. thank you
