Any tricks?



I did this once a while ago and it worked. IIRC, that hole had a clear shot into the cylinder but I'll have to take an old one apart and check again.

Right... I'm mixed up with the bleeder. Time to go to bed.

Just so any new posters or readers know, your torque specs for 86 to 87 rear banjo bolts are way high. By 2X. Haynes motor manual does say 39 for 84/85 front and rear and 30 for 86/87 front, BUT, it says only 15 foot pounds for rear of 86 and 87. That could explain your stripped threads

The following were my comments in a similar thread...

I did some further research, and the banjo bolt torque into aluminum calipers on a Subaru is 13 ft lbs. That to me makes a whole lot more sense than 33 ft lbs!

I've never had this problem of stripping the calipers, as I've never used a torque wrench on the banjo bolts (or bleeders). I've always felt that the Fiero factory torque specs were awfully high for aluminum calipers.
