Question Brake booster on a 71

I was just looking at a 71' fleetside today with discs on the front. When I popped the hood I noticed there was NO booster. How is this possible?. The proportion vavlve was there attached to the master cylinder. Am I missing something or is there a such thing as Manual discs?

Yessir, there is such a thing. Booster = power brakes. The truck I got my front end from (also a 71) didn't have a booster either.

You can wish in one hand and crap in the other.
See which one gets filled first.

Same as with power discs. More stopping power, less brake fade and heating and no adjusting needed. You just have to push the pedal a little harder.

Learn something new every day on this site. I though all 71 and 72 had power discs.

Power brakes were standard equipment in 1971 on 4x4's and 3/4 ton and up trucks. For regular 1/2 tons power brakes were an option, but were standard equipment on 4x4's.
