I’m no wrench.

I know how to change my own tires on my bike (and my car, just sayin’) and when I got a new saddle last year I put that on the bike myself and adjusted it to suit me. These are the only mechanical adjustments I’ve ever made on my own.

This weekend, I attempted to kick that up a bit to fix a problem I noticed recently on my bike where one of the brake pads was rubbing on the rim.

full frontal.

see how there's daylight in between the brake pad and the rim?

well this side don't got no day light..

so I tinkered with some stuff..

What I’ve learned is that the arm which holds that brake pad in place (and applies the brake to the rim when you squeeze the lever on the handle bar) doesn’t rebound properly after you release the lever. Since it doesn’t rebound, the brake stays on the rim.

So after tightening things up and applying generous amounts of WD-40 to the parts of the brake arm that need to move, I seem to have had some success. It rebounds now, though not as much as I’d like. 

see the tire spin freely now? that's a good thing.

I need to make sure that I keep an eye on this and check it out thoroughly before my next ride to make sure it’s in good working order, but I did go for a quick spin down the block and it seemed to function properly.

At this point in the late afternoon, my hands were too cold for me to clean the drive train like I wanted, so I’ll have to do it in the next few days. And trust me it needs to be done. There is a serious amount of crud on the gears.

By the way, I made up some of the names in this above post – I don’t know if the part is really called a “brake arm” or if the chain-and-gear system is called a “drive train” but it sounds good to me, so until I’m corrected, that’s where my head is at. This is information to me that I would probably benefit from either a good maintenance manual or a workshop. My birthday is in July, people!
