Squeel when brake pedal pushed in.

Any ideas on what problem is, when I am sitting still and press a little harder than holding still at a stop light, on the brake pedal there is this horrible squeeling sound, sounds like coming from the pedal itself??? really high pitch

1999 plymoth voyager van

Brakes are made to squeal when they are getting thin. Check what wheels the squeal is coming from.

Time for a brake job.

Just to be clear, Does this squeal happen when the van is moving or at a standstill, or both??

Only when I am sitting still.

Since the wheels arent moving it would point to a possible small vacuum leak possibbly at the brake booster. Make sure all the lines are on tight. If your not confortable with that, I would take it in to a reputable shop. But thats my guess. Hard to tell without hearing the squeal. Hope that helps some.
