I tired to replace v-brakes on my random cheap frame as spring regulation things started to fall apart. For replacement I picked front+rear set of Shimano BR-T4000 v-brakes because v-brakes are so simple and compatible with each other, right?
Fork is aluminium (or at least not reacting to magnets). Pivot stud is steel, but does not seem wrench-friendly as thick part is oval instead of segmented. Random old non-name v-brakes I somehow had on shelf are perfect match, and all around Internet I only see studs same as one I have.
Are new brakes broken/malformed/fake? Get another brakes? Use adapter part? Or should I just get new fork with replaceable studs?
Length of bore in oldies is ~2cm while new ones are ~2.5cm, wider part is respectively ~6mm vs ~3mm.
(yes yes, got new cables as well :)
