cantilever brake adjustment

Though the brake pads are close to the rim when I squeeze the levers they almost touch the handlebars.Quick fix anyone?

What type of pad posts? Does the pad have a long post that extends through a wide range on the brake arms, or is it the threaded type? If the latter, you adjust pad offset by adding or removing spacers.

Picture of your brakes and levers? The problem you mention almost sounds like what happens if you try to use regular brake levers with linear pull brakes.

It's hard to help without more information - what type of cantilever? what style brake levers?

Yeah, more info or preferably pictures would be best. Often in such cases the OP has missed something very important that they think is normal. So some pictures is pretty much required for us to see what is obvious to us but new to the poster. You also don't say if the final setup feels really spongy or if the lever feels solid when the pads finally do hit the rims.

Quoting myself ... in Road bar setups ..
Aero levers offer Less cable pull, low profile cantilevers demand More.
best not pair the 2..
Cable out the top lever (or 'cantilever pull straight bar lever)..
and wide profile calipers feel much more solid..

It's about cable pull, leverage, ratios.

I agree with you that high profile cantilevers are easier to set up, and look nicer to boot, but there are ways to make low profile cantilever brakes work. Even if you can't make it work by straddle cable height alone, there do exist things like this

To reduce the mechanical advantage of the system.

My apologies to all that took the trouble to respond but it comes to my attention the brake system is called a "LINEAR PULL CALIPER" not Cantilever.It does have a threaded post on the brake pad.The bike is at my friends so i can't take any pics.Thanks again for the input.

So it's a sort of V brake arrangement. The mini V's can use the short pull ratio of the typical aero lever. But if these are regular MTB length V/linear style brakes then you need levers that pull more cable to be compatible with the arms. What you're getting now is very typical of trying to use mountain bike style linear arms with road bike levers.

Tektro makes aero levers that are compatible with MTB length linear brake arms. And Shimano may also have such things given the rising popularity of cylcocross riding and the use of old style canti and linear brakes.

Have you worn the pads down since they were installed? Is there an adjustment screw you can screw out which will bring the pads in, and reduce lever travel?
