Mushy brake pedal after swapping my front brake pads

[blackbeast]

While I was compressing the caliper on the 2nd side of the swap, about 5 ounces of brake fluid was forced out of the resevoir even with the cap closed. Now my pedal is mushier then normal although it's still driveable and doesn't sink to the floor.

Reading online some have said this could have damaged the master cylinder or brake booster?

The first thought with the mushy pedal is air in the system but is that possible considering all I did was swap the pads?

I can firm up the pedal to a normal feel with a pump or two but then it goes back to the mushier feel.

Doh! Anyone experience anything similar to this? I'm gonna try bleeding on Friday but is there another way to tell if I damaged anything else?

Thanks in advance
