    Default brake calipers with handbrake function

    I have a cranvel fordson based tractor crane that i need to fix the brakes on. the original mechanical drum brakes have been replaced at some point with hydraulic drums from a early valiant, but they are totally stuffed. I'm planning to put disc brakes on it and would like to also have a mechanical handbrake function on the calipers, I'm sure some cars had this setup. does anyone on here know what makes and models may have had suitable calipers.

    Is there a reason you canít use a disc with the park brake in the centre hub of the disc ?

    If you've the room, you could use a mechanical calliper off a trailer.

    Thanks. I don't have enough room to use a disc with center handbrake, as it wont clear the hub.

    Relatively modern 70 Series Landcruisers have rear disk brakes with an intergrated drum for the hand brake, something like that might be suitable.

    that's the current system on my forklift, and with my hilly driveway it makes it a 2 man operation. I Really want to be able to use the crane with only one person.

    I would be interested in seeing that design, all I can find for later 70 series is the traditional shoes in the hub design.

    The Nissan Skyline / Pintara R31 series from the mid to late 80s had a mechanical handbrake that operated directly on the disk pads. These are popular for older cars being converted from drum brakes to a disk.

    If you are planning on using the original master cylinder check that is doesn't have a residual pressure valve fitted. The residual pressure is used on some drum brake setups to counterbalance the springs on the brake shoes, but will prevent the disk pads from fully retracting from the disk.

    Our Subaru Brumby has front disks with the parking brake integrated in the caliper cylinders. They work on a coarse thread system to give the required force. Not sure if they are too small for your application (the Brumby is a lightweight ute), and our '88 model has vented disks and our spare '82 has thinner solid disks....

    As many have posted, brake calipers with integrated park brakes are not uncommon and many cars have utilised them, albeit with varying degrees of success. One nasty habit that they do have is slipping when the park brake is applied to a hot disc and the disc then shrinks as it cools. Probably not an issue in your case though. They are known to be temperamental buggers once a bit of wear and tear comes into play in the park brake mechanism as well. I have a car fitted with them and I'm less than impressed with them overall. The service brake side works fine, but the park brake side of things could be better. The suggestion of using a separate cable operated caliper as a park brake could be well worth exploring.
    Given that the crane is Fordson based, is there any particular reason that you do not put it back to standard Fordson brakes? Tractor parts are generally plentiful and pretty cheap into the bargain.
