73 HighBoy Brake Question
Hello everyone. Its been awhile since I posted anything between work and sidework I have been swamped. Well to begin I have another question and maybe someone has run into this before. To begin let me tell you what ive replaced on my truck.I have installed a new master cylinder, power booster and brakepedal assy from a 76 F150 that I know works, had my drums turned, installed new brake shoes, spring hardware, wheel cylinders, and lubed the backing plate where the shoes rub. After bleeding the brakes I notice Istill dont have much pedalbut it stops good enuff for a test ride. Going down the street in front of my house it would stop but barely. I mean I was stomping/straightlegging the brakepedal and from 30mph it took 50ft. I get out and feel the drums and only the front are hot. What the hell!!!!! Im 300$bucks into this and still no binders!!!
! Has anyone got any experience, know how or magic that they could share to help me with this? Thanks in advance.

The power booster and the brake pedal and rod were taken out and installed together. The MC is straight from Oreillys brand new. I was told I could use any booster from 73 to 79 as long as I took and used the hardware from said booster such as the pedal and booster rod.

Are the rear shoes adjusted out until there's just a slight drag on the drums? they should "catch" before the fronts do, did you bench bleed the master cylinder? you may have to go around bleeding the brakes 4 or 5 times to get all the air out.

I have the same problem with my 73 4x4. Dont know if they came that way but mine has no power booster
The P.O installed new MC and front WCs. I replaced all the brake shoes, and still I have to stand in the brakes to get the truck stopped. The pedel is on the floor.
