Re: Replaced brakes, truck still hops while braking

On a smooth dry roadway where nobody else is around, keep one hand on the emergency brake RELEASE and at about 35, depress the emergency brake, while holding the release in the release position. If the truck "bounces" it's a warped rear drum or grease on one or more. If it slows smoothly, your rear brakes are probably OK. If it still surges when stopping normally, it may be a warped or dirty rotor. It has been said if the lug bolts are not evenly torqued, it can warp drums or rotors. Are your tires (very) old?
