View Full Version : Safe Brakes For Strip

I am installing a brake system on my 68 BB(396)/TH400 project car. I've used the search function and visited Pozzi's and Stoptech websites. I think my system will be safe. This is my first built car. So please bear with my inexperience. My mechanical experience is 22 years as an aircraft mechanic. With Camaros it has been just upkeep. I've never rebuilt a Camaro from scratch. This one is going to be run on the dragstrip. Very little street use.

Components I'm planning to install;

Manual disc/drum master cylinder(Cardone from Schucks $18)
Single piston front disc(69 Camaro, new calipers/pads)
Stock drum rear (haven't rebuilt yet)
Adjustable SSBC prop valve w/press gauge
Hurst roll control with install kit (ordered from Summit yesterday)
stock distribution block (original 40 yr old unit)
Manual disc/drum brake hard lines from Classic Ind.
Stainless braided flex lines (ordered from Summit yesterday)

I'm planning on ordering a new distribution block/bracket from Classic Ind. next week. The right front hard line came "prebent" but had some "straightening" done to it for shipping. This has been a pain in the butt. I've been using a hand held tubing bender and installing/uninstalling power steering gearbox to get the routing correct. I'm real close. I'm wanting to finish this so I can install the engine on the subframe. No front sheet metal installed at this time.

I was going to just put in a combination proportioning valve. But I didn't know which one to purchase since they seem to be for power disc cars. So I decided to go with the distribution block with an adjustable prop valve.

The engine specs are unknown (older,used) other than the cam is too big to supply vacuum for power brakes. I bought the engine from a friend who built the engine years ago. It didn't have enough vacuum for power brakes in his El Camino.

With 4.11 gears and stall my friend estimates mid to high 12's in my 68.

Does this sound like a safe brake system?

Thanks for your input
Brett

If you end up ordering from Classic Ind. use code WS7143 and it will save you 20% (good till end of March). Also, Classic Ind. get their brake lines from Right Stuff Detailing (http://www.getdiscbrakes.com//Default.aspx (http://www.getdiscbrakes.com/Default.aspx)). You may want to call them directly and see what deal they have as Classic Ind. does tend to charge crazy shipping costs. Super nice and knowledgeable guys as I just ordered my brake lines from them.

Thanks Matt. If I have to order lines again I'll go that route for sure. I think I got carried away when I first pulled the lines out of the box and noticed the right front was "straightened" for shipping. I over did the re-bending, due to the fact the power steering gearbox was bolted to the frame. Once I removed the gearbox and started the line installation over again I got real close to having it correctly positioned. I got real proficient at one hand gearbox installation. So far no smashed fingers. I've stopped the line installation until I get the rest of the parts in hand.

By the way Matt I read your post earlier but just now clicked on the link to pics of your ride. Awesome! Someday I envision something along those lines for my Camaro. What brake setup are you running?

My going on six year project went on hiatus for awhile. I got the fever back again and hope to see the track this summer. Planning the build has been done with safety first in mind. A few years ago (planning stage) I'd go to the pits at the track and look at Nova's and Camaro's for ideas. I was uncomfortably surprised at how dangerous some of the setups looked. ie. old suspension, inadequate brake systems for some scary fast cars(10-11 seconds in the 1/4). I've read alot here on TC and there are some helpful, knowledgeable people that post.

Thanks again
Brett

Your set up should be OK for a medium speed strip car, you may want to consider
the 11 in. drums from an Impala, larger and a little more stopping power

Brett,
I'm running (will be) Wilwood Dynilite Big Brake kit, manual discs all the way around. 12.19" Rotors with 4 piston calps. Rears have the parking brake option. I'm actually in the middle of the conversion along with the entire front/back suspension rebuild. I have the front just about finished and waiting for my new Moser rear end to get in. Brake lines should be in this week so I'll be having the same fun you did. I decided to go with new brake lines after I saw what came out of the old ones! Yes, it's all about planing, doing your homework and seeing what others did (right or wrong). I've planed the current project for a long time and saved my pennies even longer. This site is really great, as for everything you and I want to do, about 20 other guys have already done it and are willing to share their experience. Good luck and keep those fingers from getting smashed.

Thanks guys. Matt, I take it the MC is Wilwood as well?

Yes, "Polished" MC from Wilwood. A whole thread regarding the polish/finish quality in case you're interested.

What would be medium speed? Being just OK sounds like I should rethink this. I've heard of the 11 in drum from an Impala. Years of application? Parts store or reproduction catalog?

Thanks again
