Certainly could, especially at the upper end of the market.
So somewhat of a basic question i'm afraid . . can you buy these pads already in holders .

A better quality, or more specifically "linear" outer will transmit the force a lot better.

In addition to this, make sure your caliper itself is in good working order and can move freely, and that your rims are clean.
If by "linear" you mean gear cable housing, then that is outright dangerous. In the short term , it could function ok, but the steel wires of the housing, incased in the plastic casing aren't designed to hold the forces applied when applying the brakes. Ultimately, the cable will collapse, possibly quite suddenly, because there is nothing other than the plastic casing stopping the individual wires from buckling or popping out. All it takes is a nick in the plastic.

Or perhaps you meant something completely different, but I took that "linear" could only mean one thing.


They make brake specific linear cable now. Both BMX riders who want to spin their handlebars around and people running cable disc brakes who want them to responds more like hydraulics both use them.

Ok, I understand what you mean now, although scouting around on the net, it seems that "linear" brake cables are actually braided in construction. I couldn't see any that are actually linear, or are they linear under the braiding, that being there hold it all together?

I must admit that sometimes I've felt the need for something more rigid than the standard coiled outer casing, particularly with cantilever brakes. Fibrax seems to be good value at around £5 per brake.

Just got back to my original thread and postings ...

So I will for now keep the calipers and levers, replace cables and housing and by the Koolstop pads/cartridges which may well do the trick (had already considered buying the coolstop salmon ones after some conversations with Koolstop in Holland (or was it Belgium).

thanks all for your advice.
