Re: master cylinder?

The 3/4 ton master cylinder is opposite from the 1/2 ton master cylinder. The 1/2 ton has the front reservoir for the front discs. The 3/4 has the rear reservoir for the front discs.

The 3/4 ton booster and reservoir can be used on the 1/2 ton trucks.

Re: master cylinder?

Another way to tell is to look at the size of each resevoir. The larger one is for the discs

Get some new fluid and do them all so you can get rid of the old, black, chunky fluid that's in there now... Assuming you haven't been through the system yet.
