I have noticed that sometimes when braking I feel a rumble in the
brake pedal. It doesn't happen all the time though. Does anyone have
any thoughts on what might cause something like this? This is not a
question about the brake rumble noise when first starting the car,
which I know is related to ABS self test.

If I left out any needed info, let me know.

Thanks for any help.

Are you cranking the A/C a lot? Have you cleaned your throttle body,
replaced PCV valve, and/or cleaned/changed the air filter anytime recently?

G,

If you've got worn out front (or rear) tires, the ABS can falsely engage
when coming to a stop. Even having the sams SIZE but different BRAND
front to back can cause this, because the ABS thinks the wheels are not
rotating at the right speed (and they aren't).

It feels like a 'rumble' in the pedal, as you described. Incorrect
inflation can cause it too.
