Title: Tandem axle anti-skid system

Abstract: An anti-skid system for a tandem axle vehicle including an improved vehicle suspension for opposing a selected portion of the braking torque which tends to unload the front axle during breaking to eliminate brake hop. The suspension cooperates with an anti-skid circuit to increase braking efficiency. In one embodiment, the anti-skid circuit senses a skid condition at the rear wheels on a per side basis and controls the braking of the wheels on that side in response thereto. In an alternate embodiment, the anti-skid circuit senses a skid condition at either the front or rear wheels on a per side basis and controls the braking of the wheels on that side in response thereto.
