i alnthinking of swapping the front brakes in my Coupe Quattro 2,3NG to Girling G60.
What parts do i need for swapping the front brakes (now 256mm to 276mm)
do i need to change the mastercylinder too?
If you haven't already seen this, and if you (and other readers) are perhaps not sourcing all your parts directly from or for a 7A Coupe, a read-through may help with what to check for (rotor hat heights, brake line lengths, caliper specifics, etc.):
While changing the M/C may not be required, a 7A Coupe sized one (P/N's: either 441-611-021A or B?), which -may- have a slightly larger piston diameter than what you have, if so, will (by restoring the master to slaves ratio) give a higher firmer pedal feel.

2.8 had Girling 60 from the factory and uses same 22.3mm MC as 2.3 NG
2.3 NG uses vacuum servo and 7A uses hydraulic servo, can the MC be swapped between those two?
Both part numbers are NLA anyway.
If you need 25.4mm MC use one from transporter. Price is reasonable.
For ABS use 7D0611019B, need 2 new pipes from MC to ABS pump, as ports are on the other side.
Without ABS use 7D0611019A, direct fit.

That's interesting, I had no idea re 2.3 NG Coupe would have vac servo. IIRC, on my 2.8 w/ABS I swapped in an alloy 441-611-021B M/C without mods or issue, everything lined up. Perhaps that then infers this is also do-able on an NG Coupe?
On LHD, only S2, 7A (NM) and 1.8 20V Cabriolet had hydraulic servo. Cabrio was purely a clearance issue.
RHD used hydraulic servo on more models, because there is less room on that side, airbox, exhaust etc.

NG had 22mm MC from the factory. MC upgrade is not mandatory but useful I would say.
On NG quattro if you go 2-pipes MC instead of 3-pipes one you have to say goodbye to rear circuit pressure regulator under the MC.
