I wasn't meaning using only new parts, just that people are careful and do
things correctly. A friend of mine had a front brake failure that when he
applied the brakes to slow for a left turn, the wheel was whipped out of his
hand, and next thing he was over the median and into the front of a van. 2
weeks in hospital, and the loss of his pride and joy. The cause, a leaking
caliper that contaminated the brake pad on the left front. His dad had
machined the calipers about 4 months earlier, using oil as a lubricant. The
new seals were swollen, soft, and deteriorated for being only 4 months old.
When you use a cylinder hone, you get straighter walls. If you use your
fingers, and work a bit more at a particualr spot, you may create very small
irregularities in the surface, that are not visible to the human eye, but
which may cause the piston to bind, or the seal to twist and prematurely
wear. Besides, a hone will likely cost only about $15.00 to $20.00, and
storing it carefully so the stones don't get damaged, can lst for years and
many brake jobs. New stones are available anyways.
When apprenticing as a mechanic, they also teach us to use brake fluid for
this reason.
