Assembly Lubricant

I’ve used a lot of different brake lubricants over the years, and this Permatex Ceramic Extreme Brake Parts Lubricant is easily one of the best. It goes on smoothly, stays where you put it, and handles heat extremely well. After using this on my brake job, everything feels solid and quiet with no squeaks or chatter. I like that it’s ceramic-based, so it doesn’t wash away or break down under high temperatures like some cheaper greases. It works great on slide pins, caliper hardware, and contact points, and a little goes a long way. Definitely a quality product that’s worth the price. I’ll be keeping this on hand for future brake work.

Perfect for greasing caliper slides. It seems pretty durable after 1250 miles and doesn’t cause anything to stick. This grease works great especially with protecting rubber. In addition, the price of the product is very reasonable compared to others. Highly recommended this grease if you do break jobs, but make sure it’s compatible first.

This works so much better than regular or even high temp grease for disc brakes. After cleaning out the old grease I used this and then on the next brake pad change was amazed to see how well it held up and how it did not collect dirt and brake dust. It is super easy to apply and is well worth the few extra dollars to use the right grease for the right application.

#####Updated Review on Sept 26, 2025### After about 5 years of first installing the brake rotors and pads on my vehicle, I have revisited my vehicle brakes as I noticed a squeaking sound coming from the rear brakes and to my dismay the pads on rear wheel on one side is completely worn out while the other side was half left. I also noticed uneven wear on the inside brake pads (hub side) on two of my wheels; moreover, 2 out of 4 wheels had seized caliper pins stuck inside the caliper bracket. Turns out this grease is good for the metal to metal contact surfaces such as brake pads, behind the rotors, hubs, abutment clips etc. but NOT recommended for the caliper sliding pins as the chemical in this product is known to interfere with the rubber boots especially the caliper dust boots and caliper trailing pin boots (pins with a boot) . The recommended grease for the caliper pins based on the service manual is High temperature silicone grease that can withstand the extreme high temperatures generated during extreme braking. Silicon is also safe for rubber boots and parts and will not gunk up at high temps; it will also aid in the back and forth caliper pin movement. #####Original Review on May 10, 2021#### I purchased this per a recommendation from my mechanic friend who taught me how to replace brakes and brake pads. The quality of this brake grease is very good compared to the regular grease as this is specifically made for the brakes to last longer withstanding extreme temperatures such as rain, heat, cold, lots of dust, grime without creating brake noise, corrosion and for the greater good of your brakes. My friend mentioned that this grease lasts forever as he found the grease still existing on one of the car brakes that he previously installed almost a decade ago when he opened at a much later time to replace them. It is important to remember that one doesn't remove brake rotors and/or brake pads unless they have an issue with them, damaged and needs replacement. So, it's better to use the grease that can last long as there is no point in settling for anything less that cannot serve it's purpose. Use it as a thin coat on the brake caliper slide pin to ensure the back and forth movement happens without much resistance, behind the brake pads where the pistons come in contact and also on the place where the brake pad clips meet the brake mount. Overall a great quality and highly recommend this without any hesitation. Moreover, I found that Amazon has the best price around and is always in stock as some of my local auto stores did not have this particular product in stock.

I applied this around small pistons. Quad cylinder caliper on an electric scooter. I trust Permatex to a very high degree. A bit of a niche application, but........ Never any issues with their products. I expect this to be as reliable as anything.

This is a good product for its brake service purpose. Have used it for years. Shipping from the seller took a long time, but I ordered it just about a week before Christmas.

Product is as advertised but I should have bought a smaller container. I'll never use the entire bottle as a DIY mechanic.

Excelente producto

I always use this, its The best.

Gran producto que eleva la calidad de cualquier trabajo en sistema de frenos

Great product

Product delivered promptly! After dis assembly of caliper I lubed up piston and reassembled. Product stayed where I applied didn’t run all over the place. Withstood several hard breaking applications and is still there to do the job. Very pleased. Car put to bed for the winter now will see in the spring if it is still doing the job and I am sure it will be!

The product was dry when I received it. Could have been old stock as there is no date of manufacture. Not worth the amount. I would not recommend it
