After you get your master cylinders bolted in, you will want to put you "bell stops" on your brake master cylinders. The bell stops are a fail safe device. They are there in case of failure of one master cylinders. If one of the master cylinders fails, then it will no longer offer pressure against the balance bar and all of the brake pedal travel will then go to the failed master cylinder. This is a good way to meet your Maker very unexpectedly--or at least to ruin the leather in your seat. Under failed master cylinder conditions, the bell stop only lets the failed master cylinder push rod engage so far before it stops (hence the name) and forces the balance bar to act on the other cylinder. Don't forget them or someone on this forum (probably Jamo) will nominate you for the Darwin awards.
In between the master cylinders you can see the "brake guide." There is a long pin on the balance bar fork that goes into this bushing. The guide pin keeps the brakes aligned so they work properly. If you forget to put this piece in the brakes will jam and Jamo will be posting about you.
