hi i have a 96 chevy blazer 4wd rear drum bakes, need info if i can switch the drum brakes into disc brakes using stock parts from another blazer

 

Nope its not that simple sorry. The easiest way to get disks on the rear is to swap the entire axle with a newer axle with disks. Find one with the same gear ratio and its a swap that can be completed in just a couple hours with pretty basic tools. I would replace the ubolts with new if it were me though.

 

Wouldn't that effect the ABS system too?

 

I don't think so
