But this is a good thread to ask this question since people in here are looking for better brake feel.
With all the vacuum evacuated by pumping the brake pedal multiple times, how far can you push the pedal with 5-10lbs of force by your arm?

I hope LHT Performance knows that the indicator in that video is moving 0.021 inches or 0.53mm NOT 0.21 inches or "6mm" as stated in the video. I also don't believe there is absolutely no deflection after brace is installed. It would be useful to see an unbias third party test.
I used to sell master cylinder braces for Imprezas (GC) and my tests showed it decreased deflection from 0.041" to 0.021". Granted mine seemingly didn't have as solid of a connection point. There was a very slight feeling of improvement under medium to hard braking but I believe a lot of it has to do with the owner trying to justify the purchase in his mind, IMHO.
I think pad choice can have a lot more improvement to brake feel than a master cylinder brace.

However, if it does have increments of 0.0005", there are 50 increments to the 6:00 position, which would be 0.025", not 0.25", so I'm thoroughly confused.
Doesn't it seem like that to you guys?

That's what I thought, but then the reply by ckowalc with the link seems to make sense.
One of us needs to go check this on our car... Have someone step on the brake hard and if the MC is moving 6mm it will be obvious to the naked eye...

I've slightly modified my post you quoted, so take another look at it. I've also emailed and PM'd LHT so ask them to comment. But, you are right, if it's moving 6mm, you should easily be able to see it. But, why say it's moving 6mm when you are using a gauge in inches....did they also use another gauge?

Look at the before the brace results then look at the after brace results. You will notice the difference. The margin is significant..

OK,
The video we showed was very little pedal pressure to move that much. It was a scientific demonstration, but just to show slight pressure on the pedal how much it moves. The set up was very crude as a demo, The gauge was set up just to show the amount of deflection. On some cars we have seen 6-8mm movement. Just while bleeding brakes we've noticed a lot. Have someone hit the brakes while you look under the hood. Usually the first hard step on the pedal the firewall moves more, then seams to flex less. I think the firewall flexs more on older/more mileage cars)
I apologize if it's misleading, It was not designed to be more than ' Look it the firewall flex' I'm sure our brace will be ripped off in China and sold for pennies on Ebay before too long ;(

We build and sell them. We just got back from NOPI and we did the whole Dragon trip too.
We have them in stock ready to go. Send $109 shipp to LHTSales@aol.com and they will ship UPS
