  1. The front brake on my new cycle is an Avid single digit 5 rim brake.
    After only 600 miles it has started to play up, one side not springing
    back adequately from the rim after use. I have tightened the spring
    tensioner but this only provided temporary relief. A quick look at
    Wiggle shows this model to be budget (only £10 to replace).

    I can't be bothered to mess about setting up brakes before every ride
    so will need to replace them. I want a system which will last
    thousands rather than hundreds of miles. My preference is for a
    mechanical disc brake because (a) I ride a lot in the rain and (b) I
    tend to buckle my wheels frequently. One drawback is that they seem to
    drag on the pads a little and therefore waste pedalling effort (unless
    I'm wrong).

    Is it worth sticking with vee brakes or are they inherently [censored]?
    Would a higher spec (expensive) model be any more long-lasting such as
    the Avid ultimate?

    My main concern is to get something that will go for a long time
    without constant fiddling. I have spent the last 6 months playing with
    the rim brakes on all my bikes but haven't been able to get any of
    them to last. Cost is therefore a secondary consideration though I
    don't want to blow a load of cash on something that will not last
    long.

    Interestingly, to date I have had no problems with my roller brake and
    disk brake which is why I am questioning whether modern rim brakes are
    a waste of time.

    Any help, comments or recommendations would be gratefully received.

    Cheers
    Ray

    Remove the brakes, clean the bosses of any paint or corrosion, grease
    and reassemble. Make sure the cable run is smooth so the outer casing
    isn't dragging the brake arms to one side - a common problem if the
    cable has been left too long or an accessory has been fitted which fouls
    it.

  3. You could try Magura rim brakes, once set up they are totaly trouble free
    and very nice to use. I have them on two of my bikes and like them a lot.

    Why do you buckle your wheels frequently? It should be possible to
    get a decent wheel built that will stand most abuse (even if you need
    to go to downhill MTB standards) - this should be a non-issue IMHO.
    Vee-brakes are OK (coming from previous cycle brakes, they are
    'brilliant'😉, unless you spend a huge amount of time cycling through
    mud or sand (in which case your transmission will get trashed pretty
    fast too). In my experience, a disc is useful on a 406 recumbent
    front wheel (small rim mass - thermal capacity - & high speeds on
    downhills) and mechanical Avid's don't drag once set up (which is easy
    with their alignment system).
    Personally I'd just maintain your current Vee's (as others have said),
    unlesss you have a very good reason to change.

    I was just reflecting on a ride at the weekend that the wheels I was
    riding hadn't seen a spoke key since I built them seven or eight years
    ago and they still run perfectly true. In fact the only reason I ever
    take a spoke key to my wheels is if the rims wear thin or they get
    damaged on the side wall and need repair. That includes tandems and a
    full on DH bike. I'm no lightweight nor do I use other than normal rims
    and components (typically 32 spokes) I put it all down to following
    Jobst Brandt's recipes in his book.

    Yep, done all that, to both this bike and the other bike with a v
    brake. They either still don't work or last 50 miles before failing
    again. I can only assume that the springs are not made of the right
    material.

    Are you referring to the hydraulic rim brake by Magura without a
    master cylinder? They look quite interesting. How many miles have you
    done on these so far?

    Yes, self-built wheels are undoubtedly the way to go. I would be happy
    to get just one or two thousand miles before wheel straightening being
    necessary, rather than the average of 500 I currently get.

    All hydraulic brakes require a master cylinder...

    (the set on the tandem is now approaching (or past) ten years old, and are
    still really great).

    Both our tandems have 36H 26" wheels. Between us I think we probably
    outweigh you, and I can't hop the wheel over bumps as easily. But we still
    don't buckle the wheels...

    Thats what I thought Clive, but have a look at this.

    Yesss, and? A picture and description of a set of magura HS33 brakes. All
    seems in order, including the presence of the master cylinder.

    Praps its just the machine built wheels I've been buying. I'll replace
    them over time. Cheap wheels, cheap rim brakes and 20 stone of lard
    just don't seem to go well together!

    Its been a long day (((:-( I meant reservoir.

    Just wondering, what happens to braking efficiency when the hose
    expands over time?

    Yes, cheap machine built wheels are significantly weaker than proper ones.
    IMO a real false economy.

    I did wonder :-)

    Well, my sets are about 10 years old now, and I've never touched them, so I
    suspect the answer to that is "the hose doesn't expand noticably over time".

    The hose is plastic, not rubber.

    That needn't be a problem. Get a copy of Jobst Brandt's book - either
    buy it or get the library to get it for you - and then take your machine
    built wheel and finish them off with more tension and stress relieving
    by hand. Usually the only problem with machine built wheels is not
    enough tension because it lengthens the truing time significantly.

    I've had a set on our tandem since it was new. That was 7 years ago.
    The only maintenance has been pad replacement (easy) and shortening a
    hose, after one got worn through, sliding down a road. I bled at the
    time, and bled the brake when I shortened the hose.
