OBW3C may work better , if you had better brakes that featured the needed flat faces on the center-bolt spring carrier .

they work on copies of Campagnolo's brakes , which that steel budget brake is Not.


Old guys kludge technique: where the return spring coils on either side loop around to be doubled ,
can be used to bang on

with a, softer than the spring itself, drift punch (bronze, maple dowel?) to rotate the brake slightly ,
tapping on the punch with a hammer ..
