Hello. I have a 2008 Accord EX and both my eBrake levers are not functioning properly. One appears to be seized while the other is moving, but upon engaging the eBrake it will not return once I release the eBrake. I'm assuming I need to replace both calipers which isn't that big of a deal for an 08 car, but thought I'd ask the experts if there is anything else I could do before doing the replacement? BTW, I hit both levers with quite a bit of PB Blaster and that did not make an impact on there ability to move. Thank you for any suggestions.
