    Promax 85mm mini-V, need replacement

    I have a Schwinn Super Sport flat-bar road bike.

    After 1600 miles, the brakes feel mushy. Probably housing/cables need to be replaced.

    It comes with Promax 85mm mini-V (V brake). So, I had this idea to replace the brakes with Avid SD7 (100mm, $19 per). One problem..they don't fit!! Or, can I replace the stud that screws into the boss?

    Or, can someone recommend a good replacement mini-V?

    I did some research, & the Tektro RX5 have good reviews.

    Would the Tektro 926A be a candidate?

    Another option is just to keep the Promax 85mm.

    I ended up getting the Alligator Super Fortress cable kit (stainless mesh reinforced). I figure I should upgrade the brakes for this fancy cable (i.e., go with a Tektro rather than keep the Promax)

    How is it that the replacement brakes don't fit? All of those studs are the same, as far as I know...in other words, mini-Vs aren't designed to go on special studs.

    The replacement brake (Avid SD7) is different:

    - less recess (to go over the stud's "mound")

    - the pin for the spring is "raised at the base"

    as the result, the arm won't seat flush to the boss.

    Huh...that's a bit strange. I can say, though, that I've run several sets of brakes that don't fit flush onto the posts with no issues. But, that raised area at the spring pin base is definitely a kicker. I'm fresh out of brilliant ideas!

    almost looks like a plastic cover or something is missing
