...and slave cylinders...

Not sure why that posted. Started a post but got interrupted and closed my phone.
Anyway. Question was going to be. Will a mk1 escort master cylinder with no servo be powerful enough to use on track with cortina disks.
Cheers ta.

Probably... though I say that with no actual knowlage of the master or caliper piston sizes... or what car it is. I'd guess there's lots of book locosts with that combination

Probably, although it'll probably be a bit twitchy as it was designed for a 1 ton Escort not a 500kg track car. Loads of kits used the Mk2 Escort as a donor.
