1992 Volvo 940 short in compressor - blowing fuse / brake r

Thank you for clearing up the question with the short and the coolant type. A local established Volvo repair shop advised me of the short and said that the compressor had to be repalced - due to the age of the vehicle they agreed it did not make $$ sense to pay for new compressor. He was not alarmed about a potential of a fire, based on what he found at the time - but if it continues - I will take your advice and pursue further or have it inspected by another person familiar with Volvos.

With regard to the rotors, can I assume they can be turned? If not, if new pads are installed - then the worst case senario is that it will have rough braking - the slight groves in the rotor will not make the barkes not operate properly in normal city traffic? (Assumimg there are no other issues with the braking system.) My main concern is that if I replace the pads, I am very willing to have vibration on braking - as long as it is not unsafe. The vibration at present is not that pronounced and has worked for several years - approx 20K miles. The pads are getting thin at this point. Please confirm if you see any safety issues and if you think they can be turned.
