First off I will say that maybe I am being thick
I havent had parallel type v-brakes before so maybe it is me but I am having trouble getting any spring tension in some M950 v-brakes I bought recently.
If I use the middle hole on the frame (at the canti stud) everything lines up as it should but there is zero spring tension unless the screw adjuster is fully in. Even then it is not enough to provide enough to reset the brake when you release the lever????
If I use the upper hole on the frame the parallel linkage of the brake is no longer parallel to the wheel meaning the blocks don't line up with the rims. But there is plenty of spring tension.
There is significant rotational movement in the brake, Im wondering if there is a problem with them?
Its all difficult to explain so I will try and get some pics up if people have any ideas what Im doing wrong or is wrong with them.
The brakes I bought were mis-matched and came with a pair of M951 ones as well. These seem fine (but they do have an extra spring incorporated into the parallel linkage)
