Dodge Caravan - Questions

Got a few questions regarding our 1991 Dodge Caravan. Sometimes, when braking we here squeaking that seems to be coming from the rear end of the vehicle. The squeak does not happen when the pedal is depressed or during the braking, but it squeaks upon release of the pedal. Any ideas?

Also, our air conditioning doesn't really work and I was wondering if anyone had any luck with the one of the new refrigerants under the EPA's Significant New Alternatives Policy (SNAP). We don't really want to spend to retrofit to a R134a but also don't want to put in one of those "drop ins" that are extremely flammable and dangerous. It sounds as well like if there is any remaining R-12 in our older system it must be evacuated. Is this an expensive process? Is it possible there is so little left that it doesn't need to be evacuated, and could we tell? Thanks.

You need to replace your rear drum brakes or pads.


Retrofitting to 134a can be expensive. It usually requires the replacement of the refrigerant lines, compressor, sensors, etc. I would say it's not worth it on this year vehicle.
