Recently, I've noticed my Primary air guage (Rear Brakes) on my 2012 XC Chassis is holding just around 100PSI or more while cruising along and below the Secondary Guage for the front brakes and suspension. (See Photo)
Anyone else have this issue before and is it any cause for concern at this point?
Brand new Bendix AD9 air dryer and no detectable air leaks I can find though it appears the dryer purges a little more frequent than before.
Thanks for your comments.
