Hi Duke,

The reason I asked is that I was checking my pads and pushed back the piston with a C-Clamp. Shortly thereafter I realized the reservoir cap was still on, so I removed it. I replaced the cap when done, and pumped the brakes.

When the car engine is off, the pedal is rock solid. When the engine is running, the pedal is spongy. I assume air is the culprit?
