Default sudden pull

my 81 suddenly pulls right when braking. no pull when let off brake. calipers rebuilt less than 1k miles ago with OE seals.

i assume this means the left caliper is not working correctly.

what is best fix?

1) rebuild left only, OE seals
2) rebuild both with OE seals
3) rebuild with O-Ring seals
4) replace

thanks

First thing I would check is brake hoses. If pushing brakes and it pulls and while still on brakes it straightens out its a hose.

everything on the brake system except my foot replaced two years ago and worked great until now. Pull is only there when brake applied and goes away as soon as remove foot from pedal. That why I assume right caliper working correct and left not applying full pressure.

by full pressure it is not a jerk to the right but a tug that can be felt but over come by holding steering wheel firmly. My guess is that the left caliper is working some, but not full pressure to rotors.

I think I had the same problem 2 years ago, The steering wheel would try to turn every time I used the brake, to the point that on the parking lot, when I let go of the steering wheel and hit the breaks the car tried to do a circle. Is this the same symptom ?

Did you do anything before the symptom occurred ? (I did doughnuts )

Mine is not a hard pull, just a tug. Nothing happened before it. I do my donuts in mud with a truck these days

I did doughnuts the other way (left) and that fixed it!

Try bleeding brakes again, tapping(light banging) caliper with rubber mallet between bleeds. Worked for me.

I had similar issue ... New calipers, rotors, lines, m/c. Pulled hard to right when braking after working great for several years.. Turned out lower control ARM bolt came out. Look at front suspension.

Bleed all four corners. Then, if still pulling, see if the front suspension is compromised (loose/worn ball joints, control arm bushings, idler arm, tie rod bushings. If still, you may have a defective front caliper on the side that is pulling.

When I bought my '80 in 1997, first order of business was new front suspension. I don't think I ever replaced the front calipers. They had been replaced years before me. As for the rear, I replaced everything with new/rebuilt. Point is, these are old cars and if something hasn't been tended to on the list of front/rear suspension, brakes, driveline, then they are candidates for issues.
