Power brake booster for single master cyl?

[jayoldschool]

Please split the lines. On both my 65 C10 and my mint 65 Impala, I had failures. On the truck, it lost a rear cylinder. On the Impala, the master failed and leaked so slowly between the master and the booster that there was no drip. Level got low enough until the brakes failed, and I drove right into my tire rack as I pulled back into the garage. Got really luck both times. Both now have dual masters. Fabbed my own lines on the truck, and bought the pre-fab lines so it looks factory on the Impala.
