Help, no brakes!!! with Nokon Cable...(4 posts)

Help, no brakes!!! with Nokon Cable...pedalpete
May 17, 2003 10:43 AM
I've built many bikes before, and have never seen anything like this.

My brakes have NO power. Not even enough to stop me coasting down my drive way.
The levers go all the way to the bar, even though the pads are set-up really tight.
There's just no power.
The levers also don't seem to want to go all the way back to the orignal starting position, they just kinda hang half closed.
I've looked into the shifter, and I can't see anything blocking it, or preventing the lever from returning.

I've got Shimano 105 STI with 105 brakes.
Any ideas?

Someplace they're not set up right. Is the lever end of the cable in the hole that it sets in? Is it the right cable end (i.e. not MTB brake, Campy or shifter ends)? Is the inner housing tube just a little shorter than the little ferrules for each cable run? Are they all the way down into the levers? Is each of the housing ends properly seated in the cable stops?

I can't think of anything peculiar to the Nokons other than the inner tube length. Both front and rear are bad? They were good with the old cables? Can you easily push the levers to their fully retracted position even though they don't do this themselves?

Keep looking and I'll go stare at mine and keep thinking.

The cables were not seated properly. Don't know where, but I thought I had read somewhere that I was only supposed to run the aluminum to under the tape, not all the way to the lever like standard housing.

Thanks again.

Disconnect your rear brake cable. How well does the caliper work?

Now try to pull the brake lever. Does the cable pull smoothly now? If so, your problem has to be at the connection of the cable and the caliper. Read the instructions that came with your Nokon cables carefully. I suspect they should say that the little liner tube should end at the cable stop on the caliper arm, not go all of the way to the pinch bolt.
