In wet or dry conditions, if I slam the brakes hard enough, the truck stops very well, but the rear tends to drift almost turning the truck sideways sometimes when I come to a stop. Is this normal for old bolts or should I look into another proportion valve? Im running a 40mm master cyl. With a combination valve and front and rear discs. I'm guessing the rear is locking up slightly more than the front?
Thanks
