Help needed bought a remote master cylinder from SIP but having real trouble getting it to work. System bled using a vacum and got the caliper working using another master cylinder but the remote grimeca just wont get the pressure up. Have tried to contact SIP several times but they are ignoring e mails. Any ideas to get the remote master cylinder to work?

Are you sure got don't have air in the hose between master and slave cylinders? Or air in the slave?

If not then you have a leak

Bled it all mate used an industrial vacum to bleed still wont work only way it works is if we use another master cylinder think it may be the seals but it's brand new from SIP and they are not answering e mails

I'd say the seal on the master cylinder piston is u/s, or (much less likely) the bore in the master cylinder is damaged.
