1500? Leading/trailing rear brakes?

Rear brakes are wildly out-of-adjustment. Front brakes are doing all the work.

(but I thought Suburbans had Duo-Servo rear brakes.)

Failed rear circuit on master should have given you a low pedal.
Of course, the popped hose in front will give you a low pedal.
In short...I don't know.

Maybe my MC is faulty.
