Hello everyone! This is my first post here.
I've searched the web about my brakes locking issue on my 2006 QX56 but have not found a definitive solution. I'm hoping to come closer to a solution on this site.
The last couple of years, my 2006 Infiniti QX56 has had the locking brake issue happen more often and sporadically. Because of this, the truck mostly sits in the garage and I drive it only if I absolutely have to (which is rare) and I keep my fingers crossed hoping that the brakes don't act up. The brakes lock at slow speeds (fortunately); for example, when or as I'm slowing down to pull into a parking space or after I've pulled out of my drive way. To "unlock" the brakes, I'd have to shift the truck in Park (after which there'd be a pop and the truck would jump forward) and turn the ignition off then on again. I recently used the truck on a short trip and luckily no brake lock; but, I still don't trust it !!
The most promising solution that I read about was from an owner of a same year model Armada. A simple replacement of the Power Brake Booster Check Valve appeared to do the trick for him/her. I will definitely try this replacement and report back.
In the meantime, I'd greatly appreciate some input from owners who have experienced a similar brake locking issue and what was done to resolve it.
Thank you, in advance!
