Brake questions

[Bob]

I am restoring a 70 Yenko Nova that I plan to show a little and drive a lot. First question is about the brake lines, should I relace them with steel or stainless lines? Second, how do you remove the bracket from the distribution block? It looks like it is pressed(?) on. Is it better to have my power booster replated or simply buy a rebuilt one outright? Thanks.

Hey Bob;
Glad to hear the project is progressing!
If you plan to drive the car a lot, put the stainless steel brake lines on it, and use DOT 5 fluid - not the DOT 3 junk. The stainless lines are a little more expensive, and have a different look to the trained eye, but in the long run they are more practical.

I think the distribution block has a pair of 'flared' ears on it, if you tap them in, I think the bracket will come off.

Definitely get your orig. brake booster rebuilt and replated if there are no major pits in it. The booster is a dated piece, and will most likely have the stamping 'DELCO' upside down in the 8 o'clock position when you are facing the booster. If you buy a reconditioned one, you never know what you are going to get! Booster Dewey in Oregon does nice rebuild/replating, as do several other vendors that advertise in Hemmings.

Thanks. I heard you're starting another project. I bought the quarters from the fellow you purchased your car from. Back to my brake question, is there anything peculiar about the brake setup on the Yenko Novas or is everything just stock GM power disc?

Marlin:

DOT 5? Is that synthetic? We tried some synthetic fluid, but I was thinking it was DOT 4...we never could get a good pedal, even after using a pump on it.

Bob;
That's the guy, I got the car you got the 1/4's - good deal all the way around! He didn't want to break up the car/qtr's until I pointed out that they don't go together - '69 car with '70 qtrs.

Everything on the Yenko Novas is ordinary '70 power disc stuff. You have to stick with '70 though, '69's and '71 power disc items/configuration is different.

Rob;
I used the DOT5 silicone based fluid. I had trouble getting a pedal, until a mechanic friend pointed out that I had the calipers on the wrong sides. The bleeders were pointing down instead of up, trapping air, wups [img]/ubbthreads/images/icons/confused.gif[/img]

Once I got that problem figured out, everything has been fine. I have a strong pedal, and the car stops, that's about all I can ask for [img]/ubbthreads/images/icons/grin.gif[/img] (If I could keep the brake dust from getting my rims all grimy, I'd be thrilled!)
