Abstract: A method of constructing a vehicle suspension system includes forming a suspension arm having a pivot connection at an end thereof, and a brake mounting integrally formed with the suspension arm; and then securing the suspension arm to an axle. A suspension system includes an axle and a suspension arm having a pivot connection which pivotably connects the axle to a vehicle frame, whereby the axle is vertically displaceable relative to the frame. At least one brake shoe is pivotably mounted to the suspension arm. Another suspension system includes a suspension arm having a pivot connection at an end thereof, and a brake spider integrally formed with the suspension arm. The brake spider includes at least one opening which receives a brake shoe pivot therein.

Abstract: A method of adjusting a suspension run height includes: pivotably mounting a leveling valve to a hanger bracket; attaching an indicator arm to a suspension component which displaces relative to the hanger bracket; and pivoting the leveling valve relative to the hanger bracket to thereby adjust the run height of the frame relative to the suspension component. A run height adjustment system includes: a leveling valve having a leveling arm pivotably mounted thereto at a first pivot, and an indicator arm being pivotably mounted to the leveling arm at a second pivot; an adjustment lever for pivoting the leveling valve about a third pivot; and the third pivot being positioned longitudinally between the first and second pivots. Another run height adjustment system includes: a leveling arm pivotably mounted to a leveling valve; an adjustment lever for pivoting the leveling valve; and the adjustment lever pivotably mounted to a hanger bracket.
