[s-cars] S-CARS How to clean brake connectors?

[Ivan Demkovitch]

List,

I just replaced my front pads and can't get good contact on pad connectors.

Previously I had pads with no connectors and inserted U-shaped gauge 12 
pieces of wire into plugs to get around autocheck. I've got OEM pads with 
connectors but I have (O) illuminated - bad contact. I sprayed contact 
cleaner but no avail.

Is there any way to clean those pins to get contact back or I'm for 
connector replacement?

Thanks,
Ivan
