Freon type and Brake Help!! Options

[Selly_Kuhman]

Hello all. I have a few issues with my 6th gen 1996 Aniv Ed. ST 1.8 hatchback. My AC blows warm air, and I need freon. What type of freon does this type of celica take? I can get any type of freon, and I know I "should" do the conversion kit, but I am a bit strapped for cash and want to do whatever is cheaper.

The second issue I have is with my brakes. I replaced my brake pads and rotors a few months ago, and they have been squeaking ever since. I Put break lube between the shims and pads, and used caliper lube on the caliper sliders. It worked for a good 2 minutes before it started squeaking again. Any more possible issues this could be from? I was told I may have just gotten low quality brake pads, but I wasn't aware they could sell brake pads that are instantly defective and squeak from day 1.

Thanks--I have a few other issues with the car, such as valve ping, sunroof, fuse short, etc., but the AC comes first! It's been 70-80 all week in NY.

Is the R-134a stock in the 96'? I never did the conversion.

As for the valve ping, I was told to fill with 93 a few times to fix the rattle. Two mechanics told me this so I assume they are on to something, but to me it seems too easy of a solution.
