I agree 100%. I live in Chicago and do a lot of brake jobs. I used to use the Permatex purple on metal to metal contact points to prevent brake squeal and also used it on the slide pins. After a few jobs doing it this way, I noticed that brakes wouldn't squeal but also noticed uneven pad wear due to sticking slide pins. Now I only use the purple stuff on metal to metal contact points and Toyota pink silicone grease on the slide pins with great results.

Tech for over 20 yrs here. 10 yrs at dealerships, 10+ yrs at independent shops. I concur with everything he said in the video. When the Permatex ceramic purple brake lube came out our shop switched to it. I see a lot of the same vehicles many times a yr for recurring services, yr after yr. And that purple stuff is crap. So many who have been driving for decades, and never had brake troubles before, suddenly we're all having sticking caliper problems, and premature wear. And 99% of the time it was this purple brake lube used. Fortunately we got it straightened out. Unfortunately it took my shop a couple years, and hundreds of brake jobs to do so.
Oh and all my years at the dealerships, we only used the clear silicone grease.

Wonderful to impart a bit of hands on knowledge on this matter. Especially being as specific in wording."slide pins" not just "brakes". Knowledge passed on is knowledge not lost or wasted. Great job MIKE.

Finally! Excellent PSA, I found this out the hard way. Wife works rural post here in the south and uses her personal vehicle. Was told it would be perfect for all road conditions, two months later I'm having to use a torch, plyers and a sledge to beat it out, only to find that the closest place with a replacement was 30 miles away! AND Permatex's OWN product page for it, has Caliper Pins listed as the FIRST SUGGESTED APPLICATION! Happy to be the 1k like and again, great PSA vid, lots of absolutly wrong info floats around that needs squashing!

Yep. Been servicing my own cars for 45 years in Illinois. Best on pins is Sly-Glyde but you have to check to ensure the pin boots fully seal. Nothing will last if the pins seal are compromised allowing the elements to get in.

Huh, I just looked at their website and for both the green and the purple, the first listed recommended application is pins. I've personally never used the people stuff. If I recall, it's like double the price of the green. Our shop has used the green stuff for many years without issue. Before that, I personally used regular old sil-glyde. While sil-glyde seems to be thinner, I've never seen the issue described with the green grease. The main reasons we use it are the brush applicator that works great for brakes and other applications AND the fact that the color makes it easy to verify a new guy is lubricating brakes properly. We also use antiseize between the brackets and the hardware (especially on applications like rears on Ford trucks) being in the rust belt. Viscosity is higher and antiseize usually withstands higher temps than grease. I hear people say not to do that because it will just attract dirt, blah blah, but it seems to help. I've never used anything between the pad backing and piston or pad and outer part of caliper. Haven't found it to make a difference. Rarely have a noise using quality brake parts unless they get abused or installed wrong. In cases of a squeal I've generally switched to posi-quiets and eliminated it (after ruling out an assembly problem). Thing that sucks now is diminishing availability of parts of known quality. We're having to use cheaper unknown brake parts because it's all we can get a lot of the time. Or in lots of cases the centric parts we normally use are marked up to triple their normal price. A good percentage of the time in the last year, the dealer brake rotors have been the cheapest of the parts that meet our minimum bar. Anyways, I'm off topic. Will avoid purple. No issues with green here though.

Agreed!! I've works in the northeast as a tech for 20+ years and learned the hard way about most grease on pins. The last dealer I worked at only used black Sta-Lube on everything and when I serviced the same cars brakes a few months later at my next shop the pins were already stuck. It makes so much sense now why I existed in gravy brake town the entire time I was there; cleaning up the last guys grease. This is a constant PSA at every shop I works at. Thin layer of Anti-sieze to fight of rust under pad slides(if they are there), Synthetic on the brakes, slides, and squeaks, Silicone on the pins after I wash/torch/file out the last guys grease!

I exclusively use SylGlide and I'm in the same climate as SMA. Syl glide has been the most consistent for pins. We use CRC grease on the pads.

[ronijr]

I've used the 3m silicone paste and never had an issue I highly recommend it.

[thomashowell]

Syl glide is my go to even in the rust belt for slide pins.

I use Permatex 80653 silicone ceramic extreme brake parts lubricant. Haven't had a problem so far and from my understanding it's designed for slide pins, backing plates ect ect. It's bright orange as well (someone commented that management would check their work afterwards and that's why they liked the purple stuff, this stuff is easy to see too!) It's also very easy to clean up as well so you don't have to worry about making a mess that spreads all over the shop like antiseize.

[calholli]

If you're talking about "south main auto' --- he always uses silicone on the pins.. He only uses the purple stuff on slide surfaces of the pads.. I've seen "watch wes work" do the same.. silicone on the pins, purple stuff on the pads

[chargerman]

huh good to know. I'm guilty of using the purple stuff on both the pads and slide pins. Ordering some silicone grease right now lol.

[atikovi]

Permatex also makes an orange color brake lube with ceramic AND silicone that works great and no issues with slide pins. Part number 80653.

I’ve watched several of Eric O videos, and yes he sometimes uses purple colored brake pin, slides, lubricants, and in every one of those videos you see clearly the tube or bottle says silicone brake lube or grease what ever terminology one chooses to use. He also states never use anti-seize, only silicon base.

Thanks, back in 2019 did full brake job - got this purple stuff and couple thousand miles later my brakes started pulsing. Took them apart and the purple stuff on slide pins was like glue....so the pins were not sliding any longer causing uneven pad contact to the rotors. Switched to the Syl-Glide and has been much better.

Dow Corning 111 (a high-temp steam valve lube) was what we used for this at the Datsun dealerships back in the 70’s, before Nissan figured they could make more money with their own formulation. You can still get it. It’s awesome. BTW, it’s really hot here in south Texas.

[christophercaouette]

Versachem makes a brake lube with an antisqueak compound in it that works really well, too. It's blue and available from O'Reilly. To my knowledge, it's a silicone based lubricant. I've been using it for years now and had very good luck. I'm up in central Maine dealing with some pretty extreme temperature variances from summer to winter.

[Joetechlincolns]

Same goes for CRC brake lube. The black moly lube. It causes all the rubber parts to swell.

Good to see you putting this out there, I see the same all the time and it drives me nuts.
