Astro vans are designed to carry varying loads, and therefore, they are equipped with brakes that are capable of good stopping performance under a variety of conditions. Some customers who operate their Astro vans heavily loaded most of the time may prefer additional rear braking. If so, the following procedure is an acceptable method of increasing rear braking on 1985, 1986 and some 1987 Astro vans. It will result in a higher rate of deceleration at wheel slide and shorter stopping distances in a heavily loaded condition. The customer should be informed that there will be an increase in rear brake performance and the potential for rear wheel skid in unladen applications.
Astro vans, in both their original condition or as changed by this bulletin, meet all the stopping requirements of Federal Motor Vehicle Safety Standard 105 for Light Duty Trucks.
