I was real hapy with my Pac-Brake, but it has now been down for almost a total of 6 months out of the 20 months that I have had it. First find a bad relay and then wait for shipping, then I have to e tinto the shop for the repair, warranty item I could not do it myself. All was good for a while then the selenoid goes bad, wait for shipping and me being able to get to the shop, (they coverered the part on warranty even though I was a couple of months out of warranty, then the shop and I split the labor since I had previous problems). The wrong part arrives, more time for shipping and me to get to shop on a day off. All was good for a week then more problems. They believe it is an air leak, I checked all the fittings (spayed a soapy solution and got no bubbles). I will now be replacing all the air lines and fittings as a last hope. If this fails I will yank the @#$% thing off.
I made the offer to drive up to Surrey so I could get it fixed right, only four hours and I get to make a beer run also, no reply back from Pac-Brake.
I had really liked it even with the early problems but I am not a happy camper anymore.
