    I have a 1984 K-5 4WD I'm restoring. After about 10 miles both front hubs become real hot to the touch and my new motor losses power. I've replaced both calipers,discs pads and brake lines. Does anybody have any suggestions?

    Have you checked the rotors? They could be warped pretty bad. Worth a try to check them. I also have been experiencing braking headaches.
    Good Luck, Chris

    just because you put rebuilt calipers on doesn't mean they can't be your problem . I 've seen rebuilt ones that go bad fro the get go . Jack it up and see how free they spin .

    Well the brake problem does not explain the loss of power, unless you have a vacuum problem with the power booster for the brakes.....you might want to check the system out...

    The loss of power might be experianced as such due to the binding of the brakes and not have anything to do with the engine itself. Check the calipers again to see if they release properly both when cold and more importantly when they become hot during driving/use. You might also want to check the proportioning valve while you are at. Good luck.

    Did you tighten the hub retaining nuts properly? What about repacking the bearings? When you purchased the new rotors they come with new races, did you use the old bearings or new ones? What about the brake fluid?

    I my self just replaced EVERYTHING expt. the stock metal lines and rubber flex lines. If you don't follow the proper torque specifications on the front hubs you are in for trouble. Also, did you turn your new rotors?

    Oh yeah, check them bearings! I'm willing to bet the "loss of power" is really the drag of bearings that are dying. Check them and grease them before you melt the stubshaft and send a wheel flying into traffic.
