Last night I went to install a front rack on the /RadRunner Plus and had to reroute my front brake cable. By taking it out, it loosened a frayed part of the cable which then got jammed inside the cable housing, rendering the brake useless. I had never replaced a brake cable before, but a quick search told me it should be pretty straightforward. Today I was able to get a replacement cable from a local bike shop for $3 and swap it out in about 5 minutes.

The special notes were that brake cables are pretty standardized but are different than shifting cables, and that you have to match the "head" of the new brake cable with the one used in the brake lever. I was able to remove (and replace) my cable from the brake lever without tools by just aligning the slots in the barrel adjusters and pulling the cable through. I reused the existing rigid cable housing, and threaded the new cable through it. I was also able to re-use the cable-end cap from the old brake cable by sliding it off with needle-nose pliers, and then crimping it back onto the new cable. Finally, I used those same pliers to cut the new cable to length.

Performed some light maintenance and repairs on my /RadRunner Plus. I have never done much bike maintenance, but I've been slowly adjusting the brake tension as the pads wore down over the last 18 months. Recently however, my small tweaks stopped making an impact and braking power has reduced, and I needed to actually learn what I was doing. Turns out there is an adjustment screw on the brake calipers that nudges the brake pads in or out, and I needed to nudge the pads closer to the disc a bit as it wore out. I removed and cleaned both calipers with a damp rag (avoiding the pads), made adjustments, and reattached them with the correct alignment by squeezing the brake cable while tightening. Braking power is back to 100%, and the slight rub and squeak I occasionally got is gone now too.
