Stripped adjusting screw on Avid Shorty 4
I have Avid Shorty 4 cantilever brakes on my cyclocross bike with road levers. I managed to strip the small adjusting screw that adjusts the spring tension. More accurately, the hole is stripped, the screw still has threads on it.
I managed to jury rig it so I can get half stopping power.
Other than replacing the brakes, do I have any other options to fix it? I tried putting the spring into the upper of the 3 holes on the brake boss. This gives enough tension that it works poorly, but good enough until I can fix it.
If I need to replace the brakes, is there a more durable set that I should consider?

yeah, anything but avid. avids would be great if they didnt have such craptasitc tension adjustment bolts.
tektro oryx will run you 20 dollars a wheel, dont have the avid problem, and come in black or a nice silver. if you wanna get a gucci brake that takes a bit to set up, but is super powerful, look at the mafac copys paul makes. the adjustment is done with a 16 mm cone wrench, so nothing to strip out.
I've run Single Digit 7's with no adjusting bolt by shoving a very small chip of rock where the adjusting bolt would be. Still running fine to this day.
Since I stripped that adjusting bolt though, I only bend the metal arms to adjust tension and centering. Never even touching the bolt again...
Thanks for the tip on alternative brakes.
I thought about jamming something in there. I may give it a try. Thanks.
I noticed that the ring that holds the screw on my Avid 4 had cracked. Called Avid and they sent out a replacement part, free of charge.
I posted the same exact question a couple of weeks back...same thing happened to me. Even in the 3rd hole there was not enough spring tension to keep the pad off the rim. I took out the spring and bent it to provide more tension. Seems to work fine. I still want to get some better canti's for both the front and the back. No matter what I do I cannot get the fronts to stop squealing...which I hear is prety typical with shorty 4s.
I just did the same thing about an hour ago. I "fixed it" by threading in a different screw that is about the same diameter but has slightly coarser threads. If I wanted to fix it right without buying a new brake, I would run a tap through it and then buy a proper screw for the tap. Don't know why they use such soft metal with such fine, shallow threads :/
