I'm using Rotella 15W-40 in my 478 as break in oil because it contains zinc, so why would you need to add additional zinc to it?

My bad, I didn't know it already had zinc in it! haha! Thanks!

TJ,

If you think a brake line hose is going bad, change it as soon as you can. I had one go out on a 64 GMC pickup with a single pot master cylinder while coming back from a trip to the mountains with a load of trash and lost all hydraulic brakes. I was saved by the emergency brake that operates the rear wheel brakes manually. A few weeks later, the emergency brake cable broke, so I was very lucky. This was a wake-up call about how important being able to stop is. I have since replaced all brake line hoses, put in a new emergency brake cable (made locally and works great), and installed a dual pot master cylinder (where the hardest part was bending a new line to fit under the motor).

Will do! 1st I noticed it was when I had the truck on a lift, that was a wake up call just Noticing it! haha Gonna try and get it replaced today. As of now I've just been slowing down really early so I don't have to use the brakes to much. lol
