The MGA uses a hydraulic cylinder with a bore of .875". The Moss website
has the following information:
1500 and 1600 master cylinders are identical except for the covers. The 1500
master cylinder, #180-670, includes the correct 1500 cover. Some cars may
be found with Sprite/Midget 3/4" bore master cylinders. Measure your
cylinder bores before ordering internal parts!
What are the implications of the smaller bore? I can see longer brake pedal
travel and potential issues with clutch release unless a downsized slave is
installed. Am I correct or off base? I ask because I am considering going
to individual hydraulic cylinders for the clutch and brakes with a dual
circuit for the brakes.
Best,
