I have a 2006 Jamis Coda with Tektro SCD3 brakes, and one of the brake shoes is rubbing the rim. Since the other is not rubbing the rim, the problem is probably that the brakes aren't centered. The problem is these brakes have no spring tension adjustment screw. Without that screw how can I adjust the brake?

If these brakes are junk - can anyone recommend a n00b friendly set of brakes that are easy to adjust and just work?

Thanks

Single post or double post? Center pull or side pull? I can't find anything on the web about these.

First, make sure the wheel is fully into the dropouts on both sides, this is a common cause of brakes suddenly being "out of adjustment." Wheel's not sitting square in the dropouts, brakes are suddenly cocked to one side. Beyond that.........

Linear pull brakes, correct? If so, I can't imagine there's not adjustment screws on each side, near the bosses. The screws are tiny, look very closely. If you can find them, turn the screw on the side that's too close to the rim clockwise (tightening the screw), and turn the screw on the other side the opposite way. Do small adjustments, one on each side, until you get the brakes centered.

If there really are no adjustment screws, release the return spring on the side that's too close to the rim and bend it slighly outward at the base. Bend it enough to do some good, but don't go crazy with it. This will make the spring pull away from the rim more when you put it back in place. Using this method, you may have to mess around with both sides to finally get it centered, it's obviously not as precise as adjustment screws-

I just installed these on a Scott MTB.....extremely easy to install/adjust and work GREAT.....I also installed Kool Stop combo (salmon/black) brake pads.

The brake boss will usually have 3 holes on it so that you can manipulate spring tension on a single brake arm by reinstalling the spring on that side. Loosen the pivot bolt, move the spring tab to the next hole, retorque arm, and check adjustment.

old mechanics trick........if you can't center the brake, than center the wheel.

More information about your brakes would definitely be a good place to start. Different brake styles require completely different adjustments.

From what I can see on a Coda, they are v-brakes. If you don't have a little screw on either side of the brakes, period3, you could unhook the return wire and gently bend it slightly outward on the side that is rubbing. Bend it a little, rehook it, and repeat as needed. Go in small increments.

Tektro V SCD3 brakes are really simple to center. Since each of the 2 brake sections are individually mounted directly to the frame with single bolts, simply release the cable at the top & pull each section outward past their internal stops until they pivot a short distance (like a 1/4 or 1/2 inch) on the mounting bolts. If correctly tightened (not too tight, but tight enough to hold position), the mounting bolts will allow this. Then simply push both back in at the same time until they are pressed against the wheel rim. They are now centered.
