Scooterotica

Hi all,


I saw some on an ebay advert. What are the benefits of fitting them? and where to find them?

thanks for your help,

I would say that on a standard scooter with cable operated brakes, they would make no difference whatsoever, and may in fact worsen the situation (less contact area due to the grooving)

However, on a well set up hydraulic system they should help reduce fade due to better pad/ shoe/ disc/ drum cooling.

BUT.....it all depends on the friction material used, and what temperature it was designed (if indeed it was designed and not simply "altered" with a junior hacksaw in some far off back street sweatshop....) for.

Personally, replacement brake shoes and pads vary tremendously in their ability to work, so I always try to use some original "Innocenti" ones from the spares box (suitably cleaned up of course!) on a standard scooter.

Heat build up between pads and disc creates gases that try to push the pads away on a disc brake setup which reduces the braking effect, the grooves create an escape path for those gases. Not sure if the same effect occurs in a drum system. I've seen the Newfren shoes described as "Aqua", possible reference to grooves in tyres being effective in removing water to stop the tyre aqua-planing in rain but I'd imagine that doesn't apply within a drum brake. Very nice quality shoes though.

All the ones I have tried have been crap, the linings are too hard.Best stick to Innocenti originals or Indian " Mikano" ones work well.The idea with the grooves is to disperse the dust etc and keep the linings cleaner.

every thing ive ever had with drums (two wheels at least) have had grooves put in them seems to work for me

nice to get different opinions on this. I'll try them out and give my opinion to this threat.

Thanks for the replies.
