    Kool Stop and Complete LHT install troubles

    I posted this in the mechanics forum, but there has not been too much response:

    I got a set of Kool Stop Supra 2's for my Tektro cantilever brakes. I can't seem to get them set up properly. With the threaded stud from the pad at the lowest point on the Tektro brake mount slot (brake arm), the pads touch the rim barely below the tire. I measured the pads I am replacing and it was a 4mm spacing. I initially set up the Kool Stops at 4mm, according to the diagram below. I then also tried the 3mm and 5mm which neither worked.

    What I do believe the problem is that the 3 or 5mm spacers don't slide down below the "special anti-slip base" shown in the diagram. This base essentially puts another 1/4 inch of space in.

    Any help would be greatly appreciated.

    you kind of have to torque down on the brake post to get the necessary washer/spacer to press down on the striated base. how hard have you tried to tighten the pad on the caliper arms?

    By nature I am kind of a gorilla... so I pay special attention to not torqueing the crap on things. So I need to get the spacer down over the anti-slip base. That makes sense to me, but I didn't what to gorilla it, and I certainly didn't think I should have to.

    Thank you

    The dimension you'd want to measure is from the rim side of the pad to the rim side of the the brake arm; then set up spacers accordingly.
    The orig pads are curved, right? And the Supra straight? So you need to drop the pad down to prevent rubbing the tire? Maybe switch to a curved KoolStop like the MTB (http://www.koolstop.com/brakes/index...ormulated-4676)

    Also, make sure wheel is correctly positioned in the dropouts.

    I just checked our 26" wheeled LHT, and the pad is about 1/3 of the way from the bottom, plenty of space to move down for straight pads.

    Hasek,
    If the previous suggestions about applying a bit more torque to get the spacers to slide down don't work, please post a photo regarding your situation. Here is a photo of kool-stops mounted on a LHT fork with standard V-brakes.



    Though this is almost certainly not the case with you, the brakes will never line up correctly if you are using a wheel that doesn't match the brake posts on the fork. For example, if you put a 26" wheel on a fork designed for a 700c wheel, the brake posts will seem too high and the pads won't fit properly.

    Post more information if still having trouble.
