The result of this brake problem was the removal of the small spring clip that's riveted to the back of the inside brake pad. The rivet caused the brake pad to skew sideways & bound up the rotor. Removed the rivet and all is good.
As a side note, I acquired an extra pair of new speed bleeders for stock rear brake cylinders which I can't use because I have the complete 280ZX braking system on my 2dr.
If any one would like these for the cost of S&H, please LMK at the email below.
