Any attempt to bypass or disable it would likely involve tampering with the wiring harness, which is risky and could lead to other electrical problems or void any warranty. It could also be illegal in some jurisdictions.
Instead of trying to disable the chime, consider these alternatives if it's bothering you:
* Check for a faulty switch: A malfunctioning parking brake switch could cause the chime to sound unnecessarily. Have a mechanic diagnose this possibility. A faulty switch is cheaper and safer to fix than disabling the chime.
* Ensure the parking brake is fully released: Make absolutely sure the parking brake lever is fully disengaged before driving.
* Address underlying issues: If the chime is going off when it shouldn't, there's a problem that needs to be addressed, not ignored.
In short, focus on *fixing* the reason the chime is sounding rather than trying to silence it permanently. A functioning brake chime is a crucial safety component.
