Inboard disc skim

[Stu]

I've got an original inboard disc I'm rebuilding. The disc itself needs looking at due to rust and screwdriver marks etc. Is there a generally considered minimum thickness not to go beyond when turning it down?
Thanks.

I've never seen an OEM disc wear beyond reuse. I wouldn't recommend using a lathe though. These really should only be skimmed with a snow grinder for optimum finish and performance.

Just fit an aftermarket disc https://www.beedspeed.com/lambretta-dis ... p-988.html

Hi ,does anyone know off the top of their head how thick the disc is when new ?

For all your disc problems try Spondon engineering in Derby, I used to use them "back in the day" good luck.

I would be careful doing this - i recently had a pad slip out on the lever side. Fortunately I was coasting up to a quiet roundabout and the back brake and gears were enough to slow down.The pads were fairly new and adjusted, so I put it down to a worn disc allowing a bigger gap for the pad to slip through. replacement discs seem to be reasonably priced compared to taking a disc to be skimmed.

Good point.

Surely the only way that could happen was if the static pad wasn't sufficiently adjusted?

Pads are about 6mm thick and there's no way the disk should float that much if the static is adjusted correctly.
