Hi guys my motor is almost ready for the dyno and im gonna need taller valve covers.... But my question is what brake booster should i get for my 69 Camaro with stock 69 BBC frame mounts to clear the taller valve covers. I only need vacuum for the brakes mechanical distributor and electric RS lights. I think i have a 11" in it now front disc rear drum, would a 7" single dual diaphragm for disc/drum work well with my BBC 498ci solid roller cam specs 242 duration @ 50% and 646 lift with 110.
Thanks Skip

One more question, my motor builder just checked and said that my old valve covers will fit.... Should i use these and my stock booster or change them and my booster.

Should i keep this look with of course aluminum heads and water pump.

Alright maybe i should stuff it in my car and get her all ready for the massage, then later install the valve covers and possibly a new booster.

Here is a dual diaphram 8" Polished stainless steel booster and chrome master / Prop Valve combination we sell. Really nice looking unit and only $350 for the entire booster / master / prop valve set up.

It cleared out tall valve covers with no problems.

Skipper, I'm concerned that bad boy won't be pulling enough vacuum for the power brake booster!.....You'll be able to tell when the brake pedal feels hard on the second or third brake application....Hopefully you won't have to run an electric vacuum pump in addition to your stock booster!

Frank thank you and it looks like a very nice product, i will keep it in mind. Just trying to get some more feed back to decide on what i need and should do. Will this set up work better then my stock booster as far as vacuum. Also would i be able to use just the booster and save some $$$.

Ron my builder when they (Comp Cams, Brodix, my builder) decided to go with this cam spec in regards of power brakes, that was there first question. Would the booster set up that Frank has posted be better for vacuum and braking.

Thanks guys keep them coming, I'm really liking that 2nd picture i posted better then my stock pic.

The dual diaphram is a bit smaller so it requires less volume and recovers quicker then a larger unit. Also, the dual diaphram will give you increased pressure.

The Stainless Steel Dual Diaphram booster kit including Camaro / Chevelle brakets and clevis (no master or prop valve) is only $200.

And BTW, I priced it wrong and added something twice, the complete kit is $350, I corrected it.

It is a direct replacment. It is just as much a PIA as the original, LOL!

It is a direct replacment. It is just as much a PIA as the original, LOL!I wont one but i think it needs a longer rod... Can you confirm that. Also i have heard pro and cons with a smaller booster, i just don't wont to run into another delama...Thank Skip

Skip, I have the dual 8" diaphram on my camaro and the brakes work fine. Only think is I am using a electric vacuum pump. You probably need to get the motor running and tuned to see what kinda vacuum the motor has. You still will need the booster with the tall valve covers.


My booster was cadium coated and I painted it. If you need the part number let me know. I think I have the receipt on it.

Hey guys. sorry to bump in.
Im new to this forum.
Quik question for you guys, since there are some smart people who know about brake boosters.
I just got a 69 camaro, 383 stroker, weiand supercharger.12 bolt 373 gears.
it has disk brakes in front and drums on the back and no power booster.
Should i add a power booster by itself or should i get the whole setup all together?
And where does the vacume hose go?
Thank you again and sorry to jump in your thread.

Supercharge cars are not great for power brake boosters. You need to either properly size your master for manual brakes, or look into a hydroboost.

We could help with either.

can you please explain why.
How much are hydrolic brake systems?
Here is a pic of my engine.maybe you can see if thats the right master cylinder.
Thanks for the help.

Blower car make boost as often as they make vacuum, and very little vacuum in between full vacuum and boost.

That master you have is almost certain to be 1" or 1 1/8" as 90% of all Fat Boy Corvette / Z28 masters are.

A Wilwood 7/8 bore master is you best bet. Creats much more spressure and no booster hassle. Has a pedal feel very similar to a mildly asisted system, but does it without the assist.

We stock the Wilwood master, in polished and black, is $220

So what you are saying is that it would feel like you have a booster and easy on the pedal.Manual brakes suck.i have to really push on the brake as hard as i can to stop. Really scarry at times.
Does the master come with a kit or just by itself?
Can you send me a pic of the kit or part.
I live near Los angeles area.how much for shiping and how long will it take if i order from you?

Here is all the information on the master. It is all inclusive

sorry guys if i sound retarded, no afense to retarded people. i know a lot about camaros but still mechanicly chalenged.
I see that Mike with the purple 69 has a blower and has the same master cylinder as mine with the addition of the booster and electric vacume.
would i save money and have the same performance with the willwood m/c or should i do the same setup as Mike.
Mike if you have some advice please share since you have that sick ass car and probably spent thousands of dollars and lots of time.

Thanks again.

A don't sweat it im in the same boat and still have to order my booster from Frank....

Thanks for the compliment. I am running a electric vacuum pump on my car so I dont rely on engine vacuum. Long story but I had a 406 small block that only had 5" of vacuum. That is why I have the pump. Now I have the blower motor so opted to keep the vacuum pump even though the motor pulls about 16" of vacuum. You need a least 18" of vacuum for the booster to work. I would go with the master cylinder with the 7/8" bore. It puts out more pressure.

You need to call some brake companies and get there recommendations. I went thru this when I installed my Baer brakes and bought the wrong master cylinder. The bore in the master cylinder has to be matched to the bore in the brake calipers / wheel cylinders. There are guys on here that have the complete wilwood brakes with manual brakes and they say they are great.

When I called Wilwood they told me something totally different than Baer because they make there own system.

Call Wilwood, Baer, CPP about there brake kits. It will save you alot a headache. I know I had one when I was done talking to them.

Hey thanks a lot man.
I need to go take an Advil now...hehe

Thanks Frank,
Just ordered the SS Dual Diaphragm Booster from Lisa.

Hey Skip,
Glad you figured out your brake situation.
Can you tell me what kind of setup you have and maybe some pics of your engine and shot of your master cylinder.
Whats the ss boster that you ordered?

I ordered the polish stainless steel 8" dual diaphragm booster from Frank. I'm gonna re-use my stock master with my stock front disc and rear drums. The motor will be dyno this week and the cam should hold enough vacuum for my set up, but i will take pictures and give more details when i get them. Oh yeah i forgot to say in my post that i ordered those valve covers too. So hopefully i will install the booster before the motor and valve covers.

The booster will go out tomorrow, Cali is 6 days away. Thanks for your order, I think your going to like it.

Hey Frank,

The 7/8 Willwood Master Cylinder that you recomended for me, does that come with extra installation components or just the M/C? Its also polished right? Because i know they have a standard finish and a polished finish.
You said $220, how much will it be with shipping and handeling.
Im in the 91710 zip code.
Oh, one more question. I have seen this M/C on other cars and just wondering why does it sit in a angle like that. Like the top of the M/C is not parallel with the ground.

Thanks

All masters sit at a angle. The $220 is the polished unit and we ship it for $10, We also have the new black masters coming in, they are the same price as polished.

Frank,

The 7/8" bore master cylinders have a rod coming out the back for manual brakes. Have you mounted these to a booster. I talked to Wilwood and they said you could pull out the rod/ has a o-ring on the rod. But they said it might not mount to the booster due to the rod is to short or long depending on the manu. of the booster. They you might have to cut the rod on the booster if it is to long.

So have you mounted the 7/8 bore master cylinder to a booster?

that 's what i want to know too. I was planning to get that m/c and a 9" booster. I saw the same m/c(i think it was like 1.25 bore) with a booster on a 68 camaro. It looked nice (other than the weard angle) and the guy told me it worked fine.

If someone NEEDED a 7/8" bore AND a power booster, they would be masking a serious issue. A power brake system should only need a 1 1/2" bore, 1" minumum. Anything less then that is a crutch.

So no, I have never removed the rod.

Frank

Skipper....You asked my opinion ,via PM, on this booster, remember?....I told you to hold off, remember?.....You agreed!.....now WTF?.....For a dude that's 100K in the hole and hasn't got paid in 3 months, you sure are spending money you don't even have!.....I'm not mad, I'm just mad that you asked for my opinion and you do the exact opposite!:yes::mad:

Ok,

I understand what you are talking about. But why does Baer use a 15/16" bore master cylinder with there Serious Street brakes and I am assuming you can use a booster with it. At least I did. I tried the Wilwood 1" booster on my car and the brakes did not work very good. I put the one that came in the kit and they work fine now. Ended up buying a polished aluminum 15/16" bore and have no problems with it.

Who makes the master cylinder in your picture. Very nice. If I would have know about your master cylinder I would have ordered one.

Frank,
That booster,m/c and valve system you got there does look real nice.
So there is no way i can have a setup like that because i will not have enough vacuum because of the supercharger?
If i get that willwood 7/8 m/c, it will work with my excisting lines and prop. valve?

Frank,
would you know where this hose that comes out of the carb connects to.
Should i take it out and plug the hole?

Frank,
I noticed in your add for the m/c, you mention $220 and free shipping.
Do I get free shipping if i order from you?
