Brake Pads.. Ceramic verus Semi-metallic

My Lincoln MKZ has ceramic pads, and they wear very well, but they squeak a lot. Don't know if it would be the same with your rig.

I replaced the OEM semi-metallic pads on my 2500 RAM CTD with ceramic Akebono pads. They made a world of difference when stopping, especially when towing. An added plus is no brake dust on my wheels.

I don't think the heat affects the pads much. It's the heat boiling the brake fluid that's a problem on our F53s.
My 95 F53 don't stop well when the brakes are at ambient temperature, they need to warm up a little for best braking.
You may want to consider DOT 5.1 brake fluid. I believe it has a higher boiling point than DOT 4.

Also, check the outer brake pad fit in the caliper mounting bracket before you secure it to the caliper. I find most pads are a touch too long and don't float well in the bracket. It needs to float to release properly.

Ceramic can handle higher heats but carbon metallic provides better braking but are dirtier. Ask any race car driver. Most use carbon metallic.
