New Master Cylinder question

[SteveOS3]

Just got delivery of a new servo and master cylinder from Racing Green and was hoping to fit today.

I notice that the new master comes with rubber stoppers in ports 1,2 and 4 which made me think that 3 is for the 'blank'. But the old 'Saab' master has the 'blank' in 4. Could the stopper just be in the wrong port?

I could wait until tomorrow and check with them but if anyone has fitted the this type from Racing Green and could advise I could avoid more lockdown gardening work...........

Many thanks,

Steve

You're over thinking this. Just connect the brake lines wherever they need to go to suit your vehicle and blank off any unused ports.

Just fitted new servo and master cylinder and 3 is fitted with a bleed nipple to blank and 4 goes to the rear brakes via the deceleration valve - front two to front brakes.
