I need to replace the brake booster as it occasionally emits a high pitch whistle from under the dash (which I can quiet by tapping the brake pedal). Some of the parts houses sell rebuilts which I assume are actually the OEM ATEs which are rebuilt. Generally everyone carries two versions - with traction control ($350) and without traction control ($175). My car has a "STC" button so can I take that to mean I DO need the traction control version? There is supposed to be a slight difference in the diameter, but I don't know where that's measured. Does anyone know the differences in outward appearance between the two versions?

Also, have any of you performed a booster R&R? What's involved? It looks like a few things, besides just the master cylinder, need to be cleared out of the way.

Much thanks.
