Hot Rods Drum Brakes with a "modern" bolt pattern

Discussion in 'The Hokey Ass Message Board' started by buickwagon, Dec 20, 2016.

  1. Old style Model A Roadster pickup, want to run drum brakes on the front but with a 4 1/2 or 4 3/4 bolt pattern so I can still use my Wheel Vintique solids.

    whats everyone using for brakes ?? (dropped SoCal axle and spindles)

    If you have the 37-41 type spindle, get some F1 or F100 drum brakes and redrill the hubs.
     

  5. yes,redrill the bolt pattern. not hard to do .... i've done it MANY times.

    there is someone selling drilling jigs in the classifieds
     
  6. Great thankyou for your reply. Just to clarify we are talking 1949 to 1956 or thereabouts ? Thanks again

    I would suggest Econoline parts but they may be a little hard to find in Oz. Just have the hubs and drums re drilled as suggested and make sure that the hub register in the wheels will clear.

    Yes, those years work for that spindle. Not aware of any other hub that will fit the 37-41 style spindle with the bolt pattern your after, without redrilling your own.

    It's dead easy to use F100 brakes and just change the stud pattern, speedway motors have a good little bearing kit to adapt early ford spindle.
    I've done it many times and the F100 drums are superb on an early light car, in fact if you look at my Willys pickup thread I run through it on there and show what needs doing, it's quite simple

  14. sorry couple more questions regarding the brakes........ what are you using as a Master cylinder - matching F100 or is there a better option, Boosted or non boosted ? (presumably you have a drum brake rear)

    My drums are 55 F100 so teamed them up with correct F100 master as wanted period look, but I did hide a remote booster behind the dash, yes 11" ford rear drums

  16. great - Thanks again Langy - I have just found out this morning that for Australian regulations I have to have a dual circuit master cylinder such as a late Sixties Ford Falcon but should all work out fine.

    Just get one of those plastic pattern finders drop it over the pattern you have and center punch the pattern you want. The brake drum centers off the hub not the bolt pattern.

    Better use a metal pattern finder, and a transfer punch!
    Ever try and center punch a target 'by eye' and get it dead nuts perfect? Me neither...

    The OP needs to change the bolt circle in the hub as well so simply using a plastic template to drill some (presumably oversize to compensate for the lack of precision) holes in the drum won't solve his problem. The Rotten Leonard fixture is the goods if he does not have a machine shop handy that can do the job.

    Absolutely agree, a plastic template is not the way to do that job properly for sure
