Here if the aftermarket wheel has an offset that is lower than that of stock, the scrub radius is positive and can cause steering pull upon braking when coupled with other problems like bent suspension arm. Look for signs of uneven pad wear or uneven amounts of brake dust on the wheel and uneven temperatures. Take note, cars with zero or little scrub radius can have a severely stuck caliper while exhibiting very little pull. This can happen with bent front suspension components (measure camber, SAI and included angles), wheels with different offsets, or missing spacers on aftermarket wheel. The problem arises when there is a difference between the two. (That's why most all front-wheel drive vehicles have zero or a negative scrub radius to reduce the opposite of brake pull, namely, torque steer.) If the scrub radii of both front wheels are near equal, they will, in effect, cancel each other. A positive scrub radius will pull very hard while a negative scrub radius will have a minimal effect. On the whole the braking has improved by leaps and bounds after fitting tubeless tyres (Turanza) and wider alloys.Ī zero scrub radius will have little effect on steering pull if one front brake works harder than the other does. In general, the car is controllable and I am not overly worried at this point. I have braked my Santro from 130-140 kmph several times by now on the Expressway (sometimes quite hard braking) and at times I have found a tendency to pull to one side or the other depending on the road conditions. Is the car running on stock wheels? If the offset of the wheels is a lot different from that of stock, the steering could become over-sensitive to road conditions and the car could pull one way or the other upon braking. How many kms has the car run since the suspsenion was last overhauled? Problems with the suspension can certainly cause problems with braking as the balance of the car is affected, but this would have to be confirmed before you go in for such an expensive repair. Pretty much when car slow downs to complete stop at about 3-6 mph car jerks a little I guess it is transmission problem but I can not figure out the right.

I took the car to M.A.S.S and he said first try and change the tyres and then if the problem persist we will change the entire suspension. Hey sorry for creating second thread in 10 minutes, but i have second major problem with my car which has no relation to the first problem.
