Laverda brakes Brake shoes 72SF

[Trevor Crack]

Shoes front minimum 1x4.5 and1x 4.15 mm not worn evenly
Shoes rear minimum 1x3.7 and 1x4.2mm not worn evenly
I have the ‘green’ manual but not a lot about em
the minimum thickness recommended? and do they wear unevenly as these have ?
(Wouldn’t have thought so)Know a man that will fit new shoes if needed
To all you lovely Lavy people out there your thoughts are going to help a newby!!

Uneven lining wear on shoes that are (most probably) 55+ years old shouldn't even be considered, they need to be replaced to ensure a minimum of safety and peace of mind.

The aftermarket shoes that are available, sometimes, can't really be recommended. The linings are rather thin to start with and by the time they finally wear to the point where they fully contact the drum (during which the brake only performs to about 30-50% of its potential), the lever geometry is completely out the window, further contributing to the "crap Laverda brakes" myth.

The Laverda drum brake is actually a very good performer, if set up correctly. ALL slop needs to be removed from all the moving bits, of which there are many more than in a convential 2LS drum, the linings replaced with suitable material and machined to the actual drum diametre.

There's far more to it than cleaning up old brake shoes, or chucking in a new set...

BTW, new lining thickness is a tad over 6mm, providing the drum isn't worn to buggery and is, ideally, actually round and without taper. This allows optimal lever adjustments that result in a reliable, powerful brake.

Thanks very much for the info
I’m based in Suffolk so I need to find the nearest guy who knows how to technically deal with this and is aware of Laverda drum brakes

I had 8 shoes relined in Sheffield to a very high standard. They used a soft ( I chose) Ferodo material. Blasted and lacquered the aluminium shoes and I've done around 12k miles on them.

They need the drum diameter and from that they work out the lining thickness.

At least from there,you can get your new shoes profiled to match the brake drum and have control over what material is being used Which is critical.

There's many companies out there, I dealt with the owner, he knew his business
