Hi all...I've been advised by the dealer service people that they do a brake caliper lube at 48k km. Does anyone know what is involved in this and how it's done? If I can, I'd like to do it myself. This is on a 2017 CX-5. Thanks in advance
I‘ve been using AGS Sil-Glyde brake lubricant for caliper pins. But why this Super Lube is food grade and meets USDA guidelines? Is it edible?the service manual says to use a rubber grease for the caliper slide pins and a different grease for the pads. I used this for the pins
CRC Silaramic doesn't appear to be silicone. The description says " A synthetic, dry-film, ceramic lubricant ".SuperLube and SilGlide are good with a 425 degree threshold. I still have a bottle myself. I highly recommend to switch to CRC Silaramic with a 3000 degree threhold. I got a bottle at Autozone.
Silicone Grease like above = lubing the caliper pins. Why? So calipers can move freely in and out squeezing and releasing pressure of pads unto rotors. Cause of issue = that grease is either too minimal or burnt off (hence why I recommend higher heat threshold). Why silicone? Because silicone is safe on rubber o-rings and other rubber parts on the pins. Other types of grease WILL wear out the rubber parts and cause them to expand.
Burping pins = air trapped will cause the pins to sort of seize up. Pinch the rubber grommet thingies on the caliper to help purge air when you manually slide pins in and out freely.
The "Other" grease = providing metal-to-metal lubing. Since the pads' metal sides and backing are constantly grinding and being pushed against other metal components they need high heat grease that won't run off, will stay put, and is thicker. If in doubt just stick to copper based grease.
Brake Cleaner = After all this lubing going on lol!!!....make sure to wipe off the rotor's surfaces using brake cleaner to remove grease. I like to also use it to clean calipers too
KY Lube = only for extreme backup purposes.
