Replaced brake bomb today,went for a drive,and realized I had accidentally overfilled resivor.(thats what I get for searching the archives after doing the repair!) After I cleaned up the mess, I noticed the PS pump making groaning noise-it occurs when wheel is at rest, but becomes louder when wheel is turned. Could I have damaged PS pump by overfilling? Is there a prefered way of bleeding the hyd. system? THANKS!
