V-brake pads are cheaper and can offer a satisfying brake force if they are tuned properly. Along with this a set of new brake pads will increase the brake force of your V-brake system. Here you can find out what you need to know about replacing these pads.
Step 1: Firstly you need to dismantle the V-Brake to do this operation. Push the arms one to the other and get the holding piece out.
Step 2: Unthread the screw that holds the pad.
Step 3: Remember the order of the washers. They have different convex/ concave shapes to allow the pads to move on more axes when you fix them.
Step 4: To the left there is an example of cheap pads; to the right expensive pads. The differences are clear.
Step 5: Put the first two washers on the pad and then introduce it into the arm, add the next two washers and the holding nut. Tighten it moderately.
Step 6: If you think the pads are too distanced from the rim, or you want to make the travel of the lever you can make the arms come closer by unthreading the cable’s screw. After you make them come closer (not too much) put the arms back. If they will be too close to the rim the travel of the lever will be extremely short. If the distance is bigger you will be able to tune from the lever tuning screw.
Step 7: Fix the position of the pad with your hand. As suggested it must not be tightened completely such that positioning it will be possible. With your other hand push the arm to the rim.
Step 8: With the arm pushed firmly to the rim (in order not to allow the pad to move) tighten the pad completely. There is a risk that the pad moves in the direction in which you tighten its holding nut. If this happens you will have to redo the operation. A well tuned pad will ensure that the V-brake functions at optimal capacity.
Step 9: Fine tuning is present on some V-brake arms. Use it to make the pad come more or less close to the rim. V-brake arms should be parallel in the end. If they are not you should go back to step 6.
