If I'm not mistaken your truck has different front calipers than mine, my truck has the old style calipers that mount with the 2 wedges, there are no bolts or greased sliders to allow the caliper to truely float. I also think the master cylinder may be slightly larger and provide more mechanical advantage. In general the older trucks had marginal brakes at best.Not enough stopping power? My truck stops great! Especially considering all the extra weight that it's got for a half ton.
