    brake and shimmy problem

    I am noticing the rear left drum and the front left disc sticking after the rebuild. There is a scraping noise only in reverse. I'm wondering if there is some brake fluid proportioning valve that is going bad.

    As for the front end shimmy, it is an occilating rhythmic shudder noticable at speeds above 55mph and gets faster in rhythm with speed of the car.

    If both of the left brakes are acting up, then yes, that would suggest a problem somewhere near the master cylinder or the prop valve.

    As far as the shudder? Get your tires balanced and rotated.

      The prop valve and master cyl doesn't work that way. Both fronts are on one side, both rear are on the other side. Its not a left/right system.

      are you sure your tires are round? Sounds like you're describing a lumpy or flat spotted tire, a bent rim, or an out of balance condition. Bad U joints or other driveshaft problems could do this too, but you'd feel it more in the floor than in the wheel.

        I'll was hoping it wasn't the tires, but the car did sit all summer whilst I was doing the engine swap. I'll rotate them and see if it helps any. Meineke was the last people to touch my driveshaft, hope they put it back on right.

            true, but you can do stupid things like not tighten the bolts up. SOmeone on another forum had wierd shaking problems, found the bolts were loose.

              You know, if I'd thought about it for half a nanosecond, I would've realized that the master cylinder is front/rear. My bad.

                I'm not sure about drive shafts in Panthers specifically, but you can put drive shafts in wrong. They can be out of phase, out of balance, or have too much or too little angle.
