Good Evening Folks;
A while ago I posted for help in dignosing a soft brake pedal and what appeared to be an inoperative LH rear caliper on my son's '88 240 wagon. The advice was good and after ebuilding the proportioning valve to reset the brake service light we were no better off. We had changed the master cylinder at the start of this whole mess and I thought that perhaps we did not bleed it properly. Off it came and it was thoroughly bled, no change. Then, on a hunch, with my son pushing the pedal I cracked open the hydraulic connections at the master. The fwd fitting gushed fluid, but the rear one was no more than a firm stream. Ah, the 'new' master cylinder was faulty. We took it back to Advance Auto parts, obtained a replacement and presto we have brakes. Lots of brakes. I remember one of you folks saying that he had gone through three m/cyls before getting a good one. Lesson learned, just because a part is new does not always mean that it is good.

Regards and thanks to all;
