Hello All,

I have replaced a failing ABS pump in my 2007 Camry Hybrid with a used pump I got on ebay and got the brakes flushed by the dealer. On the old pump, I used to have the ABS pump make the typical whirring noise whenever I would open the driver door, but on the new unit I am not seeing that, even after a few hours of letting car sit switched off. Wondering if this is because of the replacement ABS pump being able to keep the pressure longer or if there's something wrong with the replacement pump.

Thanks in advance.
