First, Problem - Car pulls to the left when braking. This showed up after getting the car aligned.

Second, Things we have tried in order - idler arm, new calipers, new master cylinder, cleaned out proportioning valve, swapped rotors & pads side-to-side.

This is a 65 Mustang coupe with approx 1976 granada front spindles/brakes.

We cannot figure out why this thing continues to pull. It even pulls after swapping the rotors & pads from one side to the other. Still pulls to the left. Any ideas would be appreciated, thank you.

--Going to try to swap out proportioning valve tomorrow.

I don't think the proportioning valve will buy you anything, as it control front to rear. Are your rear shoes adjusted equally, side to side? Does the steering wheel actually turn when braking or does the car just drift off to the left?

I'd also try swapping tires front to back, if your tire size will allow that.

Good luck.

Try changing out the brake hose on the side that pulls. I had this problem on a truck and changed everything but the hoses. Finally a friend told me to change the hose and it solved the problem.

The rear should be pretty equal, and the rear shoes will not make the kind of pull I am experiencing... it actually turns the wheel. The proportioning valve does have some control over the front brakes as it proportions the front & the back, and has 2 ouputs for the front brakes ( 1 for left 1 for right ).

If the proportioning valve doesn't fix it, I'll def. give the hoses a try, thanks !

The reasoning behind this is that the hose can break down. When you apply the brakes, pressure can cause the hose to slightly swell. The other side grabs first and you pull to one side.

once go through all that, and still find the car pulling to the left while braking, replace the lower control arm on that side. likely the bushing is shot and is allowing the arm to move back and forth.

It's also possible that it's the strut rods. The strut rod bushings may be allowing enough flex to change your geometry as you brake and shift all the weight forward.

Click to expand...

Try the opposite side, if the hose is expanding the pressure is being expent there not to the side that is stopping.
