I am mechanically inept. In fact, when it comes to anything handy involving my hands, I am not only useless but a danger to myself. A few months ago while chopping a small piece of a tree trunk, I ended up in the ER with blood running down my face. The tree trunk objected to the axe and attacked me. Rude!
I woke up today with sore legs, the result of riding every day for a week. A few weeks ago I noted that riding daily was making me stronger. Lately, however, I’ve been feeling very fatigued from my rides. Yesterday I found out why.
One of the pads on my rear rim brakes was not releasing from the rim. This is the exact problem I had more than once on my bike tour last summer. In order to go my usual pace I was putting out much more effort than normal. In a way, it’s the opposite of a tailwind. Just as a tailwind convinces you that you are Greg LeMond, a rubbing brake pad makes you feel like Uncle Fester.
Thankfully, the interwebs have beaucoup bike repair videos. I watched four and decided I should be able to fix the brakes with plenty of patience. I also needed a day off the saddle so I figured my foray into brake mechanics would chew up an hour or so.
I put the bike up on my repair stand. Then I checked to make sure the brake cable had proper tension. I did this by squeezing the brake lever. It didn’t bottom out against the handlebar. All was good
Then I spun the rear wheel and saw that, like yesterday, the left pad wasn’t releasing from the rim. I decided to try releasing the tension on the spring on that side of the brakes. The spring makes the pad retract. The adjustment mechanism is a teeny screw. From one of the videos I learned how this works. You tighten the screw, the screw presses harder against the end of the tensioning spring, and this pulls the pad away from the rim. I tried this yesterday and nothing much happened. It was very frustrating to do this on the side of the road.
When I looked really closely at the spring, Both the tensioning spring and the adjusting screw are black and they sit in the shadow of my rear bag. It’s easy to miss where the two come in contact. In this case, when I looked very closely I could see that the end of the spring had moved away from the adjusting screw. When I turned the screw it was missing the spring entirely. AHA!
I backed the screw out and used a flat head screw driver to re-position the end of the spring. Then I re-tighted the adjusting screw. It pushed on the spring and the pad retracted from the rim.
Normally fixing bikes follows the same rule as writing computer programs. Whatever time you think it will take is an order of magnitude shorter than it actually does. If you think it will take a day to write a program, it ends up taking a week. A week means a month, and so on.
Rather than take the hour that I expected,this bike repair took all of one minute. It took far longer to set up and take down the work stand than it did to fix the bike.
This brake issue drove me nuts all last summer. I had my brakes adjusted four times between Pueblo Colorado and Carson City Nevada. Now I know what the problem was.
Tomorrow, I hit the road like an April fool. Maybe I even get a tailwind.
