Spongy Brake Pedal Feel

[Steve Tinker]

Sponginess is normally credited to air in the system, usually close to the caliper, so another bleed should bring it back to normal.
Another factor is that you say you used Pagid "race" pads which are not ideal for the road as they glaze easily. Before replacing the fluid, I would try a few (at least 3 or 4) high speed stops to de-glaze the pads - safely of course.
And if you have a Boxster S with drilled rotors, you need to clean out the holes as they easily fill up with brake dust. I use a high pressure air lance which is a lot quicker than doing it with a piece of wire......

Thanks for the input guys.

I wouldn't have said the pedal feel was "touchy" Adam, at least not after the pads were properly bedded. It just feels like there is excessive travel in the pedal before much force is applied by the pistons now. What I wasn't sure of, and you answered it for me, is whether the system would compensate for the wear by keeping the baseline pressure of the pads against the rotors constant.

You are right about the Pagid pads glazing Steve. Every so often I need to make some aggressive stops to "rough them up" again, it also gets rid of the squeal that occurs when they glaze. I have never cleaned the drill holes before, though I will start today. Thanks for that tip. If it is common to find air in the system close to the calipers then I think a quick bleed to remove the first 10 or 20ml of fluid should do the trick.

Thanks again.
