    Brakes: dual/single(?) pivot lever compatibility

    I have an old Bianchi and am not so much interested in keeping it in vintage condition as much as keeping it working. The brakes need replacing. Because if its vintage, the brakes and levers pre-date dual pivot (does that make them single pivot?). I have a line on a relatively new set of Tektro R312 for very little money but they are dual pivot. Must I switch the levers too or will my current levers work?

    Current ( non V ) road type should be fine , you adjust where the pad contact with the rim point is , in the swing of the lever

    for hand grip feel, by how far the pads are from the rim when you let go of the brake lever .

    I replace the new stock pads , on tektro brakes , because I Like Kool Stop salmon's performance/feel , better, but you can choose that later.

    (does that make them single pivot?)
    well you count the pivots and decide .. if the same bolt that holds the brake arms on in front of the fork ,
    also holds the whole brake on the fork itself, with a nut in the back, and 2 in the front, that would be the case.


    Old single pivot Campag brakes are fine by me , my only road bike has those , still , IDK maybe just putting new brake pads in may be satisfactory ..

    The release, to enable you to take the wheels out for tire/tube change, is no longer holding and it will release when the brake lever is pulled (not all the time but sometimes) which leaves me with little to no braking power.

    Those quick releases have an open and closed position, the ones on the caliper are on the cable clamp arm, often ..
    if there are none on the brake itself , often the brake handlever has one,

    if neither , just let the air out to pull a fat tire past the brake pad,
    and wait til after it, the wheel, is back in place, before pumping it up ..

    of course a puncture will deflate the tire , so if fixing a flat ,
    that is where you just wait to pump up the patched or replaced tube in the tire . till after the wheel is back in.



    of course if you show pictures , i wont have to blind guess on what specific brake you are using now. .

    You're correct again, the quick release is on the calipers. They are old Shimano 600 and the quick release is too quick to release. I've played with them lots to try to get them to stay in place but they won't always do so.

    Are you suggesting that I just leave the quick release lever in the "released" position, adjust the cables so that the brake pad to rim distance is appropriate for good working brakes and, when the need comes to pull the wheel off, there should be sufficient clearance (especially if the tire is deflated, road rim, 25mm tire)?

    Isn't there a screw to increase the friction the lever uses to stay in the closed position? , tulio's single pivot does ..

    you got ones like Number 14 pictured here ? shimano 600 brake set unresponsive - London Fixed-gear and Single-speed

    there is a screw holding the whole Qr Mech within the hole in the arm end. that may be loose. .. so not enough friction .

    lower end brakes and the latest Campag removes the QR from the caliper . just a barrel adjuster there instead
    and the cable clamp on the other arm.

    QR is elsewhere..

    These are them, the red arrow points to the release that keeps flipping up, there's nothing to tighten to keep it from flipping up (the only thing to tighten is the part that grabs the end of the brake cable which is shown as a nut just below where the arrow is pointing).
