I remember when disc brakes were first introduced on mass produced automobiles. The rumors were they were complicated, were hard to repair and shade tree mechanics would not like them.
I believed that, until necessity demanded I work on the front disc brakes on my pickup. Even with the learning curve, when I finished, I was amazed at the simplicity and ease of replacing components.
Today, I changed all four sets of pads on my wife's car. It took two hours, including the time to gather the tools and put them away. In the past, changing shoes would have taken much longer and the system with drums was far less efficient.
You really can't call disc brakes modern gizmos, unless you're getting to be an old fart like me. I'm still impressed and glad they came along.
In Case You've Wondered
My blog is where my wandering thoughts are interspersed with stuff I made up. So, if while reading you find yourself confused about the context, don't feel alone. I get confused, too.
If you're here for the stories, I started another blog: scratchingforchange.blogspot.com
One other thing: sometimes I write words you refuse to use in front of children, or polite company, unless you have a flat tire, or hit your thumb with a hammer.
I don't use them to offend; I use them to embellish.
