Hello guys, master cylinder has just started to pass back into the reservoir, as it was an old Sierra one I’m thinking of using a smaller bore size
Assuming this will give me a better pedal feel? Running escort front end with disk and rear drums, I’m currently looking at a triump dual circuit
With a 17.78mm bore, will this be suitable and what can I expect if I did want to upgrade the brakes in future to say 4 pots?
Thanks!

Or maybe a mk1 fiesta 19mm bore?

I replaced my Sierra one with the mk1 Fiesta non servo master cylinder.
Best thing I ever did! So much more feel in the brakes now, not like pushing on a solid block of wood!
Don't know how this would be affected by the upgrade though?

Hello! , do the mounting holes line up? I assume you needed to modify the pipework which isn’t a problem.

I did have to drill new holes they were about 15mm out!
Yes pipe work just needed bending to make good.
I also had to add a bleed nipple on the cylinder to blank off one port that was not needed.

Thanks pal, do you know what size fittings they are for the bleed screw?

erm no!

The same as a pipe fitting, before fitting it take to a motor factors and ask for a bleed nipple or a blanking plug for whichever one you want to delete.

Hello, got the master cylinder, I’m using a spacer instead of cutting up stuff, and also which outlets for front brakes does it matter?
