Hi gearpump and welcome to TSF,

Could you give a little more detail about how you were trying to get the back cylinder to blead? Is your master cylinder dual chambered on that year for front and rear brake seperation? When you pump the brake, does fluid level in the back compartment (assuming dual changered) go down a little?

Do you have a friend helping you at the rear wheel while you pump and then hold the brake? His job being to open the bleed valve letting some air out, then retightening it before you pump the brake again? Note that if he don't open the valve far enough to let some air out, you won't ever get it bled. The compressed air in the wheel cylinder will simply push the fluid back up the line making it look like no fluid is going through the rear lines.

Give us all the details you can, and I bet we can help.
