    Brake misalignment issues

    Hi guys

    I'm new to this forum, and I just got my first bike a Fuji Classic Track 2011.

    I'm having an issue with the front break being too loose nomatter how hard i tighten the center bolt that holds the brake to the front of the frame. The thing is the whole thing seems to either move to the left or the right after a while of use, so I always end up with one of the brakepads permanently touching the rims which isn't good

    It seems like the center bolt is the only thing that secures the whole brake to the frame and i've tightened the front and back bolt as hard as possible but i'm still able to move the brake with my hand pretty easily. It just seems like it's way to loose for comfort so I was wondering if you guys have any suggestions as to what I can do about this problem? The brake is of the brand Radius.

    Thanks

    Take it back to the shop you bought it from. It is a new bike and there are I suspect some washer/spacers missing from the brake bolt/stud or the nut is defective. You bought new so use the warranty while you have it. Roger

    +1 Either a spacer was left out or a too long retaining nut was used. In either case it's an easy and quick fix by the shop.

    Is this a really cheap brake caliper?

    I looked up Radius bike brakes on google and found what looked to me like a rebadged version of the old weinamm/ dia compe design that has been around forever. If that's the case, you have a couple of choices.

    The first is to play around with bending the return spring. Eventually you'll get better at doing it because you'll be fussing with it a lot. If it was my bike, however, I'd bite the bullet and buy a low end Shimano or Tektro dual pivot caliper.

    Hi guys

    Well I don't have the option of returning it since the bike was bought online shipped from the U.K to Copenhagen, Denmark where I live but I'm definitely gonna send them an email to see if I can get some kinda replacement brake but since this being Europe I highly doubt they'll give a customer that kinda service.

    I've already taken it apart and reassembled the brake but it doesn't seem to make any difference, anyways I'm not sure what qualifies as a cheap brake caliper? But yeah I do suspect it to be a ****ty brake like you said. I'm pondering on whether or not I put the thing back together right? now that I think of it so I can one of you guys just take a look and see if I missed something? there's a long metal rod that goes through the whole brake which is inserted into the frame and tightened with a bolt in the back and in the front there's two small "discs" a silver and a metallic one which is placed between the frame and the brake and then there's the two five sided nuts in the front which you can see too. I used all the parts and I'm 99% sure It's all right since the brake functions correctly other than the issue of being slightly loose even after the center bolts are secured tightly.

    Here's some pics I've taken, If It's all good I might just take the brake off and buy a lowend quality brake like you guys suggested

    I'm going to guess that the recessed nut is a shade too long to fit properly. It's likely bottoming on the threads and getting tight before it tightens the brake itself hard enough to hold it in place properly. If you can twist the caliper easily side to side by hand that would be the case.

    Also you really should have a housing ferrule on the housing end where it goes into the adjuster on the brake.

    And yes, going to a set of dual pivot style Tektro calipers would be a big upgrade in your brakes. But you should be able to fix the present ones with a little more study and some simple work.

    As BCRider says, it's probably that the mounting hardware is too long for the fork, and bottoming on the last thread rather than tightening front and back against the fork.

    Simple experiment to confirm. Trap a dollar bill, or 1 pound note between the brake and the fork and tighten the bolt in the back. If you can pull out the note, the brake isn't tight, and the bolt or nut is too long. If you have a recessed allen key nut the remedy is easy, file or saw off a few millimeters so it'll move farther sown on the bolt and you'll be good to go in 3 minutes.

    If the bolt goes all the way through with a nut in the back, add a spacer between the brake and fork, or a few washers in the back to take up the distance, and tighten.

    Been a while since you've been in the UK hasn't it? AFAIK, the £1 note disappeared long ago and was replaced with a coin. I think the smallest paper note is £5. The 1 and 2 Euro pieces are coins too with the smallest paper bill being 5 euro.

    The US is about the only remaining country where the smallest denomination is still a paper note and there have been three unsuccessful attempts to replace it with a coin.

    Gee, I guess using currency as feeler gauges is much pricier in Europe than here in the states. But it shouldn't be an issue since you can still spend it afterward.
