The Perrin master cylinder support brace provides the much needed support for the master cylinder and brake booster that the stock setup just can't provide. When you place force against the pedal the brake booster and master cylinder acctually bend away from the you. The sheet metal that these parts are bolted to just can't prevent movement and over time can fatigue to the point of failure. Perrin designers devised a simple plan to fix this problem- an easy to install and inexpensive brace cut from 6061 aluminum that bolts to the driver side shock tower. With the Perrin brace you are placing tension on the master cylinder opposite the brake pedal, completely eliminating this pendulum like motion. The firmed up pedal feel without any risk of damage to the fire wall makes this brace such a popular upgrade.

I installed this at the same time as SS brake lines and 5.1, new rotors and hawk pads so there was a very dramatic improvement in breaking performance all around, hard to tell what did what but I'm sure this was more effective in tandem with everything else... As far as installation I was already replacing my struts so I had the wheel and strut taken out of the car when I did it, only took me about ten minutes in that condition. Makes a nice improvement to the look of the engine bay too
Install wasn't too bad, removing the drive side wheel helped. All in all, there's less sponginess in the car, especially in a car with 190k mi.
