Brake booster question

[Christopher W.]

I have not specifically spoke to Revolution brake about the MC. I figured that since I will have Wilwood calipers front and back that the MC might need to push more volume. That is why I asked about the brake booster. I want all the parts to work correctly when it is all together. I understand that I will also be needing a brake bias adjuster.

It is hard to look at this stuff and say no. Remember I am not coming at this from a racer on a budget point of view...

Then you better be asking the people building your brake kit for you, cause Wilwood brake calipers come in different bore sizes.
To assume you NEED to change the brake master cylinder (bore) is just wrong.
You're assuming "bigger is better" but not in this case.

In fact, increasing the brake master cylinder bore size drops brake caliper effectiveness (and "feel") due to physics.
Pressure through the system drops due to (you) increasing the "square inch" part of "psi" - pounds per square inch.

Yea, like my dad use to say, "Assumption if the mother of all fu%# ups!"

I am trying to get a handle on the brake system from a engineering stand point and not from a parts consumer stand point. I just really want the look of big brakes. I know that may sound cheesy, but I do.

I now need to make that happen and not screw up my car's balance. I will stay with stock stuff before I do that...

I have found some very good articles on Stoptech's site. I wonder if I am not suppose to be post links to different vendors. Anyway, I am sure someone will tell me if I am in the wrong.

I am not real sure how well the guys I have been talking to are not just getting parts to fit as much as engineering a brake system.

Well at least I know the stock brakes are really nice. I will do some updates when I start my build thread. I have lots of other stuff to get happening now. Mainly to get my interior back in...ugh!

Any time you consider making a modification, the idea of throwing money at it, or a "Hey, I can afford it, so why not?" attitude should be avoided.

I realize you want the looks of a big brake upgrade from your other post, but on top of that, with every single modification you make, you need to ask yourself what you will gain from it, is it worth the time and aggravation of doing it, etc.

"It is hard to look at this stuff and say no" is not a reason to get something. Ask yourself what the benefits are, what the drawbacks are, and then decide if it's really worth doing. Upgrading the master cylinder may not be necessary, and might result in a lot of headaches for no real gain.

Yea, I totally understand your point and agree. I am not looking to upgrade a master cylinder for the sake of it. I could care less about what master cylinder is in there. I was thinking and probably wrong, that that would be needed.

But filling up my new wheels with big rotors is very appealing but it will only be done in a function over form way.

So, I seem to have my question answered though that I should stick with the n/a brake booster.

I guarantee that I am not just going to throw money or parts at this car. Believe me, I don't have that kind of money.....I am just a exercise coach and nutrition consultant. No fat money here.

Read the Grassroots Motorsports magazine brake primer - Pulp Friction - here:

Pay attention to page 2, as it goes into brake master cylinder bore sizing...

Personally, I don't usually trust propaganda spewed from vendors, as they are trying to sell you something.

I agree with you about propaganda from vendors. I will say that Stoptech's whole point that I read was with a properly designed front brake system you don't need big rear brakes. I am a bit of an exception because I want rear brakes for other reasons besides just performance.

Here is a quote from their paper on rear brakes. The first quote was from a customer of Stoptech.

"The folks at STOPTECH should consider developing a rear kit to match their front setup. They'll be very happy with the performance improvement if done properly." Well, since our FRONT systems are designed properly, we save you the need to spend your money on the back axle. Let's reword that quote to reflect the STOPTECH philosophy: "Our competitors should consider developing a FRONT kit to match their stock bias condition. They'll be very happy with the performance improvement if done properly, AND will save their customers the cost of a rear brake upgrade in the process."

All of that being said I am not going with Stoptech. I have today talked to the guys at Revolution Brake and got the answers that I was looking for. They are not part fitters. They are brake engineers. They actually take in account all of the stock systems specifications and try to replicate that as close as possible with the larger Wilwood rotors and calipers. They use computer software to do this. They said that they can usually get the brake bias damn near spot on to the original specs. They said if it is a little off it usually tends to add a slight bit more towards the rear than stock.

They see no problem so far with the stock MC. They haven't crunched the numbers yet so we will see....I should have my kits by the third week in July.
