I have a couple problems: on long right or left hand turns, feels like car changes from oversteer to understeer? which, but it begins to pull into the turn by itself - there does not appear to be play in rack. I also have brake vibration when at speed, if I pump not as bad, new rotors and pads were installed, helped for short time. ??? ??? carnut

Were the calipers lubed? did you/they torque the lug nuts or use a impact gun? Have you checked the air pressure in the tires? Tried swapping tires from front to back? What brand pad did you use? Post back, Transman

Yup, lubed the calipers, Bendix pads, Raybestos rotors (made in Canada). Calipers have some play. Vibration is not terrible, but still there. The pulling into a curve is unnusual feeling as if switching from oversteer to understeer mid turn.

Thanks

Are the struts original ? If so it's time to upgrade.

Something about Ford PS I don't understand, seems to have a mind of it's own, especially around curves, can actually feel the steering wheel move in my hand like it's trying to over control. In all my cases, a good flush cures it, jack up the front to take the weight off the wheels, jury rig a hose to the PS pump return line into a container, start the engine and idle it with a helper constantly turning the steering wheel from lock to lock, fast, while pouring in fresh PS fluid into the reservoir, do this until the fluid comes out clean plus a little more. Reconnect the return line, engine off of course, top it off, and seems to correct this problem.

Make sure that line into the container is tied down, it will whip out and fluid will fly all over the place. Normally buy about four quarts, run three through and use the fourth for top off. Worth a try.

Also something about Ford brakes with that vibration, let the car sit for a couple of days and new pads and rotors will vibrate like crazy, but eventually goes away after making several stops or even many stops. Something about a little surface rust on the rotors and the geometry of the calipers, I never found a cure for this, part of driving a Ford, I guess. Took that 95 Escort for a ride last week with new pads and rotors that sat for over a month, our Bird, Continental, ZX2, a 2000 Taurus are all the same, first time you hit the pedal swore the front end is going to shake off, with that Escort, after 80 miles of driving, finally tamed down.

I let my 92 DeVille sit for four months, pulled to the right after the first 20 mph stop, then was okay, but just something about Fords, maybe somebody else can explain why. Even my 82 Chevy P-30 that sat for six months had two rough stops, then was okay, put all new brakes on that last year, had to pry the old ones out, cleaned and properly lubricated everything so I could put it together with my bare hands, that is the only way to do a brake job. If you can't put it together with your hands, something is wrong, even hand centering the calipers.
