Reply to "Seeking ideas concerning what may be causing the car to pull to the left when braking."

You've covered most of the common possibles, my friend. Other things that sometimes causes sudden steering problems is tire inflation pressure differences, alignment shifts especially on high-crowned secondary roads and internal brake hose partial-failures. Unless you are an originality;aficianado, I suggest a pair of dash-3 braided stainless or braided Kevlar hoses to upgrade the rubber stockers. 16" long fits all 4 positions. If you use ss-braided, they will machine metal off cast wheels so watch the routing. The vendors sell the aircraft grade hoses with a fitting that screws right in to the calipers and the stock junction block, so no jumping thru hoops to get things re-attached and no great expense.

On the weird side, one guy found that in replacing his rotors, he had received parts from two different casting runs. The coefficient of friction of the cast iron was different for the two rotors. He only found it by swapping the brand new rotors side to side.... and the 'pull' followed one rotor position. He was sensitive enough to feel the change in friction coefficient. I suppose the same thing might be possible with aftermarket brake pads, too. And there's always the possibility that the right side rack bushing may have come loose from its pressed-and-screwed-in-place position inside. That will allow the right side end of the rack shaft to rise and fall while turning the wheels, giving an 'odd' feeling. Good luck- J DeRyke
