I'm a Pacbrake fan. Had it installed before I picked up my new ride (had same system on my '96 3500 with no problems). But... .....
Now the brake baffle is sticking in the exhaust elbow of my '02 and staying on, not shutting off immediately. Super Lube spray doesn't help. I bought my ctd new in Sept 2001 and have just over 30k on the clock. HERE'S THE GOOD NEWS: Pacbrake is gonna replace the brake and cover the labor for the reinstall. HOT DAMN! This is a good deal warranty, eh. Can't find easier guys to work with than at Pacbrake. They do know their stuff and are most helpful.
As an aside, when ya wash down your engine compartment, use a baggie as a cover up over the soleniod so no water gets into the breather knob on the solenoid. Also, if ya ever have to pull the solenoid down for a "clean & polish", it's no big deal and the guys at Pacbrake can walk ya through it. Hope this is heplful.
