I recently had a BD exhaust brake installed at Oregon Fuel Injection and had them install the E-Knob from Geno's Garage to activate the E-brake. The knob rattles internally and gets pretty annoying at certain RPMs when cruising
I like the feel of the E-knob and the convenience of the on/off button, but the rattle is enough to to lead me to search for a solution or switch (pun intended :-laf )to the Pac-Brake design. Anyone have a similar experience or a solution?
