I have noticed that after driving for a while and the engine bay is hot, not necessarily that I have been braking hard, like if I come off the interstate after a long drive, that the brake pedal is very, very soft. Almost to the floor and required pumping to brake. Any ideas as to what the culprit may be?

I have new pads and rotors on all 4 wheels and still seem to have the problem.

Just check that the Clappers are free (not binding) and have a competent mechanic do a thorough Bleed on your Brake System.

Clappers?

I did later today find out that I have a little seepage, maybe a couple drops at most under multiple full force brake pumps, from the point where the brake hydrobooster mates to the master cylinder. Would that help with the diagnosis?

A Clapper, is a part of a Disk Brake System
HowStuffWorks "Disc Brake Diagram"

Yes, any leak in that area, could cause a soft pedal, and should be repaired.

Thanks. Clapper, AKA Caliper? Or totally different?

HA, it's the same thing

Sort of like breaks aka brakes.

Thanks. Going to replace the brake booster. Anyone have a link to a DIY?
