I have a pull to the left on the W126. The pull is proportional to brake application. With light braking it is non-existant. With moderate braking it is slightly noticeable. With heavy braking it is quite apparent.

I have performed the following to diagnose:

1) Taken all the pads out, thoroughly cleaned and lightly lubricated all the caliper slides and pins.

2) Verified that all eight pistons will easily retract into their bores.

3) Replaced the rear pads (down to about .100).

4) Confirmed that none of the pads are "hanging" after the brake pressure is removed.


It would appear to me that neither the calipers nor the brake hoses are the culprit here. Any other ideas would be greatly appreciated.
