The FSM says use lithium soap base glycol grease for the piston parts and disc brake grease on the inner anti-squeal shim. I have Sil-Glyde BK-4 brake lubricant, Sta-Lube SL3301 brake caliper synthetic grease, Super Lube with PTFE (rated at 450°) and CarQuest Disc Brake Quiet #2065. Can I use any of the products I already have, or do you recommend other specific products. I have uneven wear on my pads. Primarily, the top piston on the driver's side is causing extreme wear on the top of that pad.
