    I did some designing this morning for a disk drive shaft brake. Thought I would post pic and get comments, questions, feedback, etc....
    I have a wilwood caliper and would need to mount for that, I would also need to mount a small master cylinder and convert stock parking brake lever to accuate.

    What is the reason of hydro over mechanical?

    Willwood makes small mechanical units....All pro was selling this for the mini's for a while.... I know a guy that installed it on his 60 after some work...

    http://www.allprooffroad.com/brake.html

    Seems to work fine being mechanical...I guess the cost and hassel to make it hydro would not be worth my time..

    Let me know when you get these done...I will take a few without holes for the driveshaft...

    Thanks!

    -Steve

    I didn't realize they had a mechanical model, need to do more homework. A friend had the hydro model he let me have, before that I knew nothing of them. ::)

    major dia is 7", do you think we'll have any clearance issues?

    What is the largest diameter of the original parking brake drum? I am at home, not at the shop. I am going out there shortly..

    E-brake is supposed to be mechanical according to motor vehicle requirements. That way if hydraulics fail you have a mechanical back-up. Personally I think it is stupid but I don't make the rules. Most places don't do a tight enough inspection to even notice if the E-brake even works let alone see if it is mech or not.

    The drum is over 7" while the backing plate is around 8" so if your skid plate clears with a drum your disc design should be no problem. You may want to make the disc a seperate part from the drive flange so it could be changed or replaced. If the disc had the large and the small bolt it would fit a wider variety of vehicles for the same cost of manufacturing. The original drum can be machined down to make the drive flange and disc can be bolted to it.

    yeah, I planned on making two piece. You don't want to waste the time turing that thing out of a solid 7" hunk of steel. Then, if you ever need to replace, just drop the drive shaft and remove 4 bolts.
    I checked my drum to be about 7 1/2" diameter. there souldn't be any clearance issues. now, how wants one? get enough orders and i'll fire up the Daewoo and start spitting them out.
    What would you be willing to pay for such a slick part as this???

    So the rotor is one piece, and the hub is another, and the driveshaft bolts hold the whole mess together, right?



    10 bucks....hows that?

    actually the disk would mount to the flange with seperate bolts, this would be the easiest way.

    i'll have to charge you extra poser for removing holes, just for the trouble. ;)
    maybe you'd pay 11?
