Brake Servo failure

Hi Lads

The brake servo on my sti hawk is leaking brake fluid.
Can I replace this with one off blobeye? Or doesn't it have to be one off another Sti Hawk?

If it's coming out of the servo there's something wrong with the master cylinder.

Yes a doddle but will need the whole system bled.
Make sure to prefill the cylinder.

I haven't removed the cylinder yet , but what seal normally goes?
Is it a brake cylinder seal kit that i need? Got quoted £98 for kit, do i need a kit or a single seal.
Brand new master cylinder for £210
