I have been looking for insight to the Jake Brakes on a 903. I have seen an offhanded comment on a trucking forum about them being hard on the valve train of a 903. I realize its all subjective but does anyone have experience with Jakes on a 903 causing problems, excessive wear etc.... provided they are maintained and set to spec? Jacobs Engineering does not support the product on the 903, even though they support their other Jakes of that era. Should I take that as a sign I should remove them, or just keep them in spec realizing they will never be worked as hard as in a truck, and prob be problem free?
