    looking for a specific part for brakes on a 1970s Gitane street bike, pics inside

    I'm looking for a specific part on the brakes, the nut with the hole through the middle that secures the brake cable to the caliper arm with the complete circle. Sorry, I don't know the correct term, but I've tried to include a couple helpful pictures. I'm looking for both the bolt and nut. Anybody know where I might find one. Thanks

    I tend to go for readily available parts as most vintage bikes are nothing special but if a vintage bike was in mint condition that was rare with all-original parts, I would NEVER modernize it.

    Its a work of art and changing it would destroy the character and value of the bike.

    You have center pull brakes, not caliper brakes. Look up photos online or on ebay. You need a straadle cable and a yoke, no joke.

    oddjob is right about what you need, a straddle cable and yoke for both front and rear. (but i'm not sure the cable he linked will work.) you may also need the cable hangers for both brakes. the front hanger stacks along with the headset. the rear hanger is kept in place by the seatpost bolt.

    i'm working on a peugeot right now with this same brakeset, mafac racers. the straddle cable is merely any shift cable for a road bike. so you need two shift cables. you also need the mafac fittings for each side of the cable. the head of the shift cable fits in one of the fittings (which then slides into one caliper) and the other end of the cable is secured with a nut and bolt on the other caliper

    it may be hard to find these small mafac parts. but it looks like ebay is selling individual calipers for $10ish a piece. that way, you would also have the missing pad holders or any other missing parts. or you could try the bf c&v "iso" thread.

    about the missing mafac pad holders ... it's not wholly necessary given the cantilever pads you are now using, but they do look a lot nicer. and paired with kool-stop pads for mafac, they might provide the best stopping power ever offered on a vintage bicycle. the pads are definitely worth the $23 on ebay. i had them on my '80 pkn10, and bought them again for my '74 pr10.

    and ... it's just semantics, but both center-pulls and side-pulls are caliper brakes. they don't attach to the frame/fork like cantilevers.

    by "fittings" above, i mean parts 460e and 59 as shown in the schematic. part 469 is just any road shift cable cut to size.

    maybe someone will chime in with an alternative solution if the fittings are missing.

    yup, that site has the two fittings for $5 each. they're listed under the schematic on that page. you'll need to weigh this cost with buying the whole replacement brake on ebay, which might be a few dollars more but also offer more replacement parts like pad holders.

    From that second pic it looks like you may have a hard time with it. The two halves of that hole look to have been pinched together by someone tightening a bolt across them so much that the pieces are bent, squeezed together. You won't be able to get the straddle cable in there easily. MAFAC brakes are readily available so you might just want to look for a whole new set.

    Yeah, it looks those would be the parts I need. That link above to the vintage brake parts was pretty helpful.
