booster/master cylinder
I recently had the booster go out so I ordered a reman booster and master cylinder combo. Well when i go to press the brake it have brakes but the brakes stay engaged, and the pedal stays to the floor. So I ordered a new one which i got today and upon disconnecting the brake pedal I think i found where I might have caused the problem my self. Could putting the brake arm on the inside (the gas pedal side) of the brake pedal cause it. Which side is it supposed to be on.
btw its a 78 f150 Ranger Lar. 4x4 351m 4-speed

If the booster is off right now, get me the FTE# off the end of the booster push rod
It should be FT-39
They may have given you the wrong one as there are SO MANY to choose from.
On the fornt of the booster where the MC attaches there is a bendix number,.
it should read ' 12300 '
Get me the numbers and we'll sort this out for you.

Other ideas
Just replaced the Booster, Master and hard brake lines to the proporting valve on my sons 77 F150. Also did new rotors and calipers.
Just to double check did you
0) Have fluid in the system
1) Is the check valve OK or new
2) Bleed the brakes-while opening the push rod on the portioning valve
3) How are your calipers/ rotors- could one be jammed tight? Do the front wheels spin freely when lifted.
4) Are pins that connect Booster bracket to the brake pedel jammed or siezed
Just some ideas beyond having the wrong set-up.
Let me know how it works out.
