Spongy Brake Pedal Feel

[Daniel R]

About 9 months ago, I changed out the worn brake pads for Pagid race pads and also did a complete flush of the brake fluid. The brakes after that were nothing short of amazing, just a light tap on the pedal and the car stopped. Lately the crisp pedal feel is gone, and I wouldn't say it is spongy, yet I am used to a lot better feel.

Now for the questions. Is the pedal softer because the pads have worn down (there is still about 70% life in them judging by eye) or is it that I need to flush (or at least bleed) the fluid again?

I don't really want to go through the process if it will not help, but don't mind the 30 bucks and a couple of hours one lazy Sunday flushing the fluid if it will give me that "new brakes" feel again.

Thanks in advance.
