Brake booster

[scr8pnHard]

Is the brake booster the same from 86.5 to 93? I found one for 20 buck down the road and I Think I need one. I have no back brakes and I put a t in the line and shut the back off with stopper. but now when I drive about 10 miles the front brakes locks up and I have to bleed both calipers and then its good to go for another 10. I have check the adjustment under the dash and all is good. If it is the same I can try it anyways. The truck has set for awhile so I put a new master and all on it just lost on this.:crazy:

Is the load sensing proportioner still in the back? if so check it that would cause your back brakes not work. And your booster wouldn't have any thing to do with which brakes work. hope this helps.

Nope, I have no back brake at all. Took the lines off and I have put some stops in the front with a t so it would act as if both cylinders was working but just work the front. The brake works great for so long and then the front brakes goes to locking and I can feel it. Then I get off the road and go under the hood and open the bleeder on both front wheels and then frees it up and I can go for another 10 to 20 miles
