Use special grease for ceramic brake pad assemblies
Grease things up: Where to apply brake grease
Wipe ceramic brake pad grease onto brake pad abutments, pad slide hardware and inside the caliper’s slide pin boots.
If you do your own brake jobs, chances are you’ve switched to the newer ceramic-style brake pads. They’re much cleaner and quieter than semi metallic pads. But they don’t dissipate heat as well, and that high heat can degrade the grease in caliper and pad slides. So it’s critical that you use synthetic high-temp brake pad grease to lubricate the caliper pins, pad abutments and pad slide hardware.
Now there’s a new type of grease made especially for ceramic brake pads (one choice is Permatex No. 24125 Ceramic Extreme Brake Lubricant; about $17 for 8 oz. through our affiliation with amazon.com). The high-temp lube contains ground-up ceramic particles that act like ball bearings to ensure proper caliper and pad movement. Apply brake pad grease to all slide areas as shown.
