    I believe it was so he could hook the parking brake back up. /forums/images/graemlins/thumb.gif Pretty sure 3/4 ton Suburban backing plates for your year of truck is what's needed. /forums/images/graemlins/thinking.gif Not everyone does this though.

    Ok, there are 2 different e-brake setups.

    The first one runs from '73 to '82 on the 14FF in which both sides of cables are equal length and at the backing plate end, the cables are held in place by 2 small bolts. The cables being equal length each fasten to a bracket by the forward part of the rear springs.

    On the '83 to '91 plates, the passenger side cable runs over to the driver side and hooks up to a single bracket by the driver side rear spring. This type of cable is a press-in style rather than bolt on, much like most cars have.

    So, the basic explaination is that most people with the newer ('83 on up) trucks swapping in an older 14FF ('82 and older) want to retain the e-brakes and will need to find the plates from any FF or SF from '83 on up. Yes, even the SF 3/4 ton rears share the exact same size and will work evenly in place of the older axles.

    Now if you try to use 1 ton brakes, the backing plates and drums are a different game. Those are wider drums and the plates recess deeper than the 3/4 tons.
