Hi Schurkey, very helpful reply. Do you know what the difference front and rear between the JB7 and JB8 brakes are? I have the JB7, but may consider upgrading. Still, it stops just fine with the Camper, which, btw, is rated at 2,800 lbs empty. Filled with all the equipment; water (but no poop!); and accessories a fair estimation is 3,500 lbs. Thanks. PMy '97 service manual says JB8 varies between single-rear wheel and dual-rear-wheel vehicles. Both rear brakes are 13" drums x 3 1/2" shoes. The front brakes are different--12 1/2" rotors 1.26 thick on single-rear-wheel vehicles, 12 1/2" rotors 1.5" thick on dualies.
