    Went to check out a Model A this morning. The seller was selling the frame, axles, springs, rims, and tires as a package for CAN$700. He had mentioned to me in the phone that their “juice” brakes, and this was really all I was after, so went to check it out. The fronts definitely seem to be juice brake backing plates sans the cylinder, but the rears were hard to tell, so asking for help in identifying if the rears are juice backing plates as well.

    Front.

    They are all juice. The rears are upside down, and installed on the wrong sides.

    Yes, they are juice brakes. Backing plates have been switched side to side to put wheel cylinders on the bottom probably for clearance issues. Wheel cylinders will just need to have bleeders on the top.

    Damn, I am slow at typing!

    Haha! Thanks! Saw what looked like a bleeder type fitting or for a brake tube. Is the tube up top for the E-brake cable?

    Are these plates worth anything? The frame is badly pitted in some spots, but is not hacked, cut, or botched. The torque tube is also badly pitted. I’m still waiting on hearing back from my machine shop on a second flathead I picked up a couple months back. If it is good, I thought the frame etc could be a starting point for a second project. Lol! He had no interest in selling the body bits.

    Yeah it’s for the e brake, I’d grab them if cheap enough. Worse case they might have hardware that can be a pain to find when you just need a bit or a piece down the road

    Model A frames are pretty rugged and have been the basis for lots of cars. For my tub, my boss was throwing away a "junk" A frame and he gave it to me. I had to weld up 134 holes and patch in a spot by the steering box that had been repaired with a license plate for a backing. After boxing it, it handles the power of a stout SBF just dandy.

    42-48 brakes. The fronts look to be adapted to Model A spindles. The rears are upside done, the tube is for emergency brake cable.

    One thing I noticed. . . . The bottom adjusters look to have been torched off on all 4 backing plates. Rears are flipped as stated and the adjusters are melted off. They are supposed to look like the upper adjusters with hex head bolts. Good luck with it

    This is the difference between 39-41 brakes and 42-48. The lower pivot does not have cam adjusters on the 42-48. Just a stud pointing inward that a sliding brass cam rides on. Can’t make any adjustments to the lower half manually.
     
  13. Using upside down reversed side backing plates was how I ran the 46-48 brakes in my 29 Tudor back in the early sixties. It was standard practice and I had no real problem bleeding the brakes.

    Yeah. They are both the same, but I have a pair of good ones. Still on the fence. To pick it up, I’d have to rent a car hauler.
    The machine shop said he would get back to me within a month when I called them on 8 July. Still waiting…Lol!
