Master cyl. size?

[DLM06]

I need to replace master cylinders. What size mc is best? I want to keep them both the same size. Calipers are superlites. Thanks.

1" if you want them the same. 7/8" will give you more pressure but less pedal feel.

Agreed, I will add I like the bigger 1" as the pedal effect is higher so you have less tendency to lock the brakes. However if your pedals have a low ratio to them you might like the smaller one. Most pedals are in the 6:1 to 7:1 range and works well with the 1" M/C's.
