I own a 2017 Silverado 1500 with a pulsating braking issue. It happens on the passenger front only for no apparent reason. The pulsating will continue long enough for the rotor and the rim to get steaming hot. I can feel the truck lagging and it starts to tremble. The first time it occurred I actually thought my wheel was falling off. The length of time it is happening varies each time it occurs. Sometimes it stops while driving and other times I have to sit the truck for awhile. No warning on the dash cluster. The flex hose looks good and the caliper checked out ok. Any help would be appreciated.
