Where did you look?

I have the engineering release charts for all GM brake systems starting in about 1969.

The attached link happens to be a scan of the '87 system, which should be the same as your '86. You'll need to know your truck's GVW in order to determine the correct brake system (JB6, JB7, etc).

And you didn't mention 2wd or 4wd.
