Thread: Push to lock brake - broken spring

  1. #1

    Exclamation Push to lock brake - broken spring

    Hi, I drilled out the rivets and extracted the spring. Apparently it's a torsion spring but I can't find anything similar online?

    I was wondering if any of you have had to buy a complete new brake assembly just because of a broken spring? Buying a new brake seems such a waste and unnecessary expense for the sake of a spring

    NB: It's an Out-Front composite as fitted to Tilites.

    My sympathies are with you, but I had to chuckle about this. The spring on my horizontal brake broke and someone on here suggested a fix was to use a rubber band, showing photos with his post - it looked like a good fix. I chose to leave it as is because the brake itself works fine and it doesn't wander after I release it.

    It's vexing that so many high tech things (wheelchairs, for one) always seem to have a "weak link" that causes trouble.
    Wonder if you could consult a machinist to make up another spring? Looks like it's made out of a coat hanger wire. I can't tell the size of the opening of the spring, but maybe a needle-nose pliers could be used to wrap suitable wire around, to fashion a temporary fix.

    It was a good fix, but unfortunately I don’t think it works for Rowan’s type of brake.

    Rowan, perhaps try Alibaba...various vendors say that they can make up any size/type you want. https://f2rq3.app.goo.gl/?link=https...3451073&amv=69

    Looks like the composite and other locks use the same spring. Part number CP102415 or CP102416, depending on which side of the chair. I have ordered one before, I think through Sportaid.

    $5.00 a spring here. https://www.southwestmedical.com/rep...e-scissor-lock

    This is for composite scissor brakes but looks like it might be the same.

    Good to know that you can purchase those springs from somewhere. But I wonder how much the “spring installation tool” costs?!?

    It's useful, but not necessary in order to install the spring.
