    E brake too much tension

    Hi,
    I just installed my mustang parking brake and the rear wheels are binding. With the handle released there is quite a bit of tension. It took some effort to connect the cables. If the cable on the park brake was a half inch to a inch longer it would work great.

    I looked up and saw that the park brake handle automatically adjusts the tension tighter. I have to figure out how to release it.

    Look at the handle, there are two sprockets. Disable the drive side sprocket temporarily and release the spring. We then set the brake and drill a new hole in the main sprocket. The key is to have NO tension on the cables when handle is down. Then work when pulled. It is a bit of a fine line. HTH, Richard. PS make sure you understand how it works before you do all this.

    Thanks
    I don’t quite understand the reason for drilling a hole. Is that to pin it temporarily?

    I also did not see anywhere in the directions to cut the spring. However I believe that might take care of the problem. I just hate to do something permanently that may be the wrong thing without at least some guidance.

    Can I remove the spring?

    I'm not sure either, what Richards means about drilling a new hole? My e-brake already had a hole in the cable pulley, I used for pinning it, but my e-brake was from a 90 donor, so the new ones may not have that.

    You could remove the spring I suppose, although simply disengaging it should have the same benefit. I believe there was another thread on FFCars, that described how that is done.

    That's good to hear. Like I said, I wasn't sure if that was required any longer with the later model handle.

    Curious why it worked OK for Sean? His calipers have heavier return springs, or slightly longer cables?

    Everything on my ebrake setup is (new) OEM Ford stuff. 1995 GT handle, cables and (originally) calipers. I've changed the rear caliper/rotor style over time but the brake handle/cable setup has remained the same and it continues to work as designed. I even use the handle release switch Ford built in to activate my DRL module! I can understand the need to modify the handle when switching from rear drums to discs, but I can't see any reason to modify any of the components from OEM rear disc setup to get the ebrake to work in the roadster. All the components (handle, cables, calipers etc.) were designed to work together. Go figure?

    When you say to disable the spring do you mean temporarily or permanently?

    This picture is one mod that was used on the pre 94 donor handles.



    The idea was that the self adjuster on the donor handle, was no longer needed when using disc brakes, instead of donor drum brakes. The concern was with using disc brakes, if the adjuster ratcheted up a notch, it may cause brake drag. Brake return springs on a drum brake were much stronger then a disc brake, and could overcome any tension from the cable. The handle basically became a lever with a pivot point, to tension the cable. Like the new FFR optional handle is, and the Lokar handles some use..

    Now I have no idea if this same mod would apply to the later donor (94+) handle though, as it may have come from a Mustang with disc brakes. It well may be the handle's self adjuster just needs to be released a notch or two, to give the cable some more slack.
    Hopefully someone using the later model donor e-brake handle can chip in.

    I have all 1995 GT era (new parts) handle and cables etc.. No modification of handle or spring was required with either the stock GT rear calipers/rotors, Cobra upgrade or the Lincoln MK VIII calipers I have on now.

    I am running 95 brakes and didn’t modify the handle. It works perfectly and self adjusts as designed.
