Grooved brake shoes?

[jjwithers]

Does anybody sell brake shoes that have grooves in them? (for a /5)?

The seem like an upgrade by allowing multiple surface areas to grip the drum, and also allow some air for cooling and brake dust venting, etc...

Is there a way to add grooves to the shoe compound?

Thanks.

You could groove any brake shoes you want with a die grinder and a composite disc. I'd wear breathing protection and use a powerful vacuum cleaner or fan to make sure I wasn't breathing in any brake dust.

You may want to check, but there may be an Ipod app for that.

Angle grinder? It'd be the "airhead" way.

Do stop tho' when the sparks start!

Like hell! The Airhead way is a triangular file - or, perhaps, a hacksaw blade.

JJ, your speculation is not based in science as I understand it. Grooves might prevent gases from the pads from helping allow the material to slide/skip over the drum, but they will not provide more cooling, "multiple surface areas," or vent brake dust. So, it is not impossible that grooving your shoes might improve your braking, but since it will also reduce the amount of friction material actually contacting the drum, I don't know if it will actually result in any improvement in braking. Even if it could make your braking better, I don't know how you could know how many grooves of what dimension would be most likely to provide a benefit.

Unfortunately, it would be very difficult for an owner to actually test this idea in any scientific way and know if it was making any real difference in his braking. Not impossible, but certainly difficult.

I see it as a wet condition improvement/experement as drum in puddles and rain do suffer some lesser stopping power if water gets into the drum

you could load the brake lightly to keep dry too! but a channel shoe could prove useful to the user..................


a fully bonded shoe could be drilled like a disc about 8 ea 1/4 hole would do it and give some lighter weight to the whole bike

I have an old motoren Israel paper catalogue, in it there are some rear brake shoes for a late 800 GS with diagonal grooves. The shoes are made by EBC.

Must get back to the Olympics, UK versus the Aussis cycle team pursuit,

Ditto that bicycle raceing rocks

And the UK team won!
