What a hassle this turned into...
I bought what looked to be the female counterpart to a T-40. The female counterparts are not called "T-anything", they're "E-whatever". I eneded up with the E8. Got home, the damn thing didn't fit. Too small.
That was on the driver'* side. So, for *&Gs before going BACK to Napa, I tried it on the passenger side. The passenger side had 10 MM HEX HEAD bolts. I was really bent at this point.
So, I tried Boost'* suggestion with the 7 mm socket on the torx head bolts...no go. 7 MM too big. 6 MM was too small. Finally, I ended up getting them off with a 12 point 1/4 box end.
THEN, I went to Napa to return the incorrect tool (the E
and bought two fresh 10 MM bolts and locking washers for the driver'* side.
It'* all back together now. I'm still not super happy with the stopping distance, but my 162,000 mile ORIGINAL shoes and wheel cylinders are fresh. And, my front brake pads are new as well. Maybe I have a slowly failing master cylinder....although, I'm not sure of the signs of a failing MC.
