Ok so I'll be using the O.E.M hub/brake asembly on my rocks and wondered what u guys reccomend for MC/Booster combo? I'll also have pinion brakes but those will be my emergency brakes and be cable activated. Should I just switch to a 1ton MC/Booster or should I jump over to hydroboost. If I should go hydroboost what PS pump should I get? One from PSC?

If you already have pinion brakes why mess with the heavy drum brakes ? The pinion brakes will stop it just fine

They won't stop shit. The truck will be driven at almost 70mph. I don't think pinions will do anything

He means OEM as in Oueverson Engineering. With Disks.

But I normally hear people say the pinion brakes are too grippy. The main complaint is that they can get really hot or if you break a shaft=no brakes.

You realize the fact that the brake is on the pinion multiples the braking force by 6.72 times in a rockwell diff? The downside is the rotor then has to dissapate all that energy turned to heat quickly and they just aren't big enough to do that from high speed regurlarly.

Your pinion brake should still work even if you have a broken shaft.

What about with an open diff?

Oh and if you have unlocked selectable hubs, it's useless.
