I have had heard descriptions of flat spotting the rears during panic stops. My question to those who have experienced this: Were the only wheels loosing traction the rear axle? I have had my GMC since 2006 and it was incapable of locking up any wheels except on wet roads. After installing a Bob Stone hydro-boost on my coach, the rear stock drum brakes do lock the rear axle as well as the front 80mm calipers. The stock mid axle drum brakes do not seem to lock. However, there is significant deceleration going on. The front end actually nose dives. I was toying with the idea of replacing the mid axle wheel cylinders with 1 1/8" cylinders and the rear axle with 7/8" cylinders to better balance the braking. So again, have you experience front and rear axle wheel lock-up or only rear wheel lockup?
