hydroboost ?

[oldmechanic]

does any one know what the difference is between the booster on a truck with
rear drums & one with rear disc & could they be interchanged on the 96 in my sig

Thanks,Cecil

Call your fav parts man and ask him to run the numbers and see if there is any real differences.

I doubt that the Hydrobooster is different.

The master cylinder likely is though.

There are several iterations of the Hydroboost (The one on my motorhome swarfs those on pickemups, as does the master cylinder.)

The O'rielly on line parts book shows different part #'s & the drum brake one has a adapter on the return fitting with a tube back to the housing was just wondering what the difference was I have 2 trucks with drums & one has the adapter & the other does not
