Help with replacing just the master clutch cylinder

So I recently had a Valea single mass flywheel clutch kit installed and had them do the slave cylinder too. Recently I found that the master is leaking now. The guide below talks about doing both at once. Can I just pickup the procedure in the link below at figure 7? Do I need to worry about compressing the slave cylinder (already bled) before working on the master? What do I need to do before removing the master cylinder to prevent putting air into the system? If I just use a turkey baster to get fluid down to the line like it is shown in the link before removing the master cylinder is all the fluid going to still leak out once I remove the master cylinder? If I replace just the master cylinder what needs to be done to bleed the system or make sure there isn't air in the system?

You will need to bleed at the slave, as it is the only point in the system with a bleeder.

Install the new master, use a slave compression tool, pressure bleeder (makes the job a one man affair), and you'll probably have to do multiple bleed procedures to get the system cleanly bled.

Is there any way to replace it and bleed it without a power bleeder? If I leave the cap on the reservoir should just a small amount of liquid leak out of the existing master cylinder and its lines when I remove it?

You'll create an air pocket, which will need to be bled from the slave, as it is the only point of the system with a bleeder.

You can bleed it without a power bleeder, but once you use one you'll never want to work without it.

Ok thanks. When I swap out the master cylinder do I need to remove and compress the slave during the bleeding process or can I just swap out master, hook up power bleeder, and open up bleed on the slave until I see the air stop coming out?

To do it properly you need a compressor on the slave, I'm sure that you could run 3 bottles of fluid through the system without compressing the slave and have a 95% bleed, but to do it right you'll need a compressor.
