Clutch lever dead

bobbertandsammy · 20-09-2018, 09:13 AM

Evening all, I was fortunate enough to purchase the 750 Madhatter was selling and I'm now looking at recommissioning it for the road. Theres one job I'm not familiar with and its the clutch, the lever is totally dead. Does nothing, no pressure nada. It looks like - if it was a japanese bike - the master cylinder needs a quick rebuild with a kit. I have now learned that you cannot buy these from Brembo and its a replacement part required at about £120.

Question is does anyone know of a kit you can buy for rebuild or can I recondition the one thats on the bike? Was hoping to get an MOT on this before the bad weather properly arrives.

Cheers for any help

Try bleeding it first start simple and cheap and work your way up difficult and expensive ladder

I got a few brake refurb kits from http://www.duetorrimoto.co.uk
If you do need odd or hard to source parts give him a go.

There’s nothing to bleed buddy, the master cylinder is basically frozen.

You did say the clutch lever did nothing, no pressure not that it was seized so which is it?

If it is the 'coffin' type they have a rather nasty habit of going a bit gungy where the bare alloy inside reacts with the brake/clutch fluid and the moisture which they absorb and will easily block the hole into the piston itself which may well be the cause of it not working properly.

If it is seized up then obviously you have other issues in which case I would get the whole assembly off the bike and see if it can be freed off.

If it has the PS13 master cylinder then you can buy a kit here:
