How Things Work [Travel day filler]

Today is a travel day. We’re off to visit with Clare’s mom for a few days, and then to Massachusetts to visit the kids and grandkids, with the older kids in their new, early-60’s home. I have a list of projects, so I’m taking a bag and a box of tools with me.

This post is for MaggieMae.
Squeezing a brake lever on the handlebar pulls the brake cable (toward the lever):
» This pulls the brake arms (green arrows).
» Since the brake arms are anchored to the bike frame at the opposite end (orange circles), the brake arms are pulled in toward the center line (yellow arrows).
» The brake pads (red ovals) are pulled together against the rim of the wheel, resulting in a braking action.
Clear as mud?

@maggiemae This one’s for you!

Interesting!

[Maggiemae]

Its on the rim - the brakes? Not the tyre itself....I feel better advised now. Very clever manipulation here!

@maggiemae Oh, gosh, not the rubber tire! The pads pinch in on the smooth metal rim for smoother, more controlled braking.
