I found this on FEEDs site a while back...

I wonder if they're charging $500 for a brake master cylinder with a bigger reservoir, or whether it actually has a change in the cylinder size in a way that increases the braking power? Their description of the product is really vague, since all it says is that you get "stable braking."


Or would you need their $1,500 kit that is basically just two big rotors and two mounting brackets for 4-pot calipers (and some machining of your hubs)? Of course, the kid would also require huge wheels (17-inch rotors).



...I'm being sarcastic and curious at the same time.


They're almost as bad as RE-A... Yes, $100 for 5 liters of synthetic oil!


Although, if there were any bolt-on modifications that would give an FC the modernized braking feel reminiscent of an RX-8, that would be...totally sweet.

 

If you want a bigger master cylinder you can install a TII MC (bigger) and booster (stronger). Apparently the 1" 929 MC fits on the S5 TII booster as well for an even shorter throw.

One thing to try first is a brake master cylinder brace. You can make one fairly easily out of some steel bolted to the strut tower with a long bolt pressing up against the master cylinder. It helps reduce firewall flex for a better feeling pedal, it really works wonders. Get a freind to press hard on the pedal while you watch the MC and you'll see it move a fair bit.

 

Changing the master cylinder does not improving braking "power". Your car will not stop any faster.

 

I know that.

Although, I was wondering if there were bolt-on MCs that would decrease pedal effort.

 

I got the impression you didn't know that when you asked "whether it actually has a change in the cylinder size in a way that increases the braking power?"

Most people changing the master cylinder fit a larger bore one for improved feel, which also increases pedal effort. That's most likely what the FEED one is.

Why do you want less pedal effort? Our systems aren't exactly heavy.

 

Well there's those 2 other options there that you can get from your local dealer, junkyard, parts store or wherever.

The TII setup probably won't have decreased effort, but it will give less pedal motion, the 929 MC will be a little stiffer and even shorter.

Seriously though, make an MC brace, they're cheap and easy to make and make a big difference.

 

They are when you have fairly sticky tires and single-pot brakes with street pads.

I figure it'll be better when I get four-pots and SS lines...

 

Upgrading to better pads with a higher coefficient of friction will help reduce pedal effort.
