Has anyone had this problem with their BD Brake?? I installed the exhaust brake on my truck last month. The day after it was installed, the brake turned on while accelerating up an on ramp to the highway, with the power switch on. I turned the switch on & off, but the brake stayed on. I stopped the truck, checked the micro switch on the gas pedal (ok). I then unhooked the vacuum lines, swapped them, and the brake opened up (turned off). Reattached the lines to their original postion, and it's been fine, till this week. The same thing happened again, but this time it will not shutoff when the vacuum lines are put back on. I'm assuming the spool valve is stuck. I called BD Technical Dept. yesterday, told them of the problem, they agreed it's the spool valve. I know there was a good article in the TDR on cleaning these valves, but only being a few months old, I don't feel I should have to do this myself. BD told me they would ship out a new valve and bill my credit card. Once my valve was retuned to them and proven to be defective, they'd send me a refund. I've never had to pay for a warranty part with any other company. Is this how BD handles all of their warranty claims?? As you all know, these are not cheap items, and i hate the thought of spending more to get it working again. Should I try to solve this problem myself, or send them more of my hard earned money. Sorry so long.
