Adjust Avid 1D V-brake- no tension screw for springs
I'm trying to get my Avid 1D V-brakes adjusted and centered- there is no screw on the side of the arm to adjust spring tension. I have been unable to get them perfectly centered- one side always hits before the other. I know I can put a wrench on the spring flats while tightening the mounting bolt, but is there a trick to getting them centered? Thanks.

Are you sure they are called 1D, think is should be 'Single Digit'; this will be prefixed by a number, normally 3,5 or 7
If you look at the manufactures website, there are tech docs on there, which will show how to setup / adjust
https://www.sram.com/en/service/avid/...D=1&subcatID=2
DO NOT BEND THE SPRING, this will not adjust the brake, will invalidate any warranty. Look at the instructions, and adjust it properly

They are one of the older Avid V-brakes, from 1997. As far as I know, they only say 1D on the brake, aka SingleDigit.

These look like the SD 10 brakes, which appear to be very similar to the current SD3 & 5 brakes
If you look at the manual for the Single Digit 3's you will see a piece on the back of the brake where it attaches to the fork/frame brake boss, this has a crosshead screw or allen wrench bolt, which is the alignment adjustor, It's clearly visible in the photo on this link. https://www.socaltrailriders.org/foru...xt-739-rd.html
If this is missing, the brake can not be adjusted, and really should be replaced by a complete unit

im going to guess you put a cone wrench on the square in the back and loosen the mounting bolt a little, tension with cone wrench and tighten the mounting bolt. the left brake spring also looks like it has been bent
