(51297 mi) Leaks and a spongy brake (or don't reuse old rubber, stupid)

Hydraulic action is a pretty simple way to transfer force from a source to a destination, if you don't have any leaks or bubbles.  I had both.

The leaks came first and were caused by two factors: old rubber and stupid me.  "Stupid me" re-used the old boots on the wheel cylinders after I re-conditioned them.  They really did look supple and new when I decide to reuse them.  Unfortunately, after a trip across the country from Chicago to Los Angeles , they degraded.  "Stupid me" also didn't double-check all the hydraulic linkages for tightness.

"Cups-Old cups should always be thrown away when you're overhauling a system."p. 19, Master Technicians Service Conference,"The ABC's of Hydraulic Brakes", Vol 1, No. 8, 1948.







Replacing the rubbers was not a problem.  The brake pad adjustments are another story.
