Raybestos vs 3m silicone brake lubes

[GophersGarage]

Hi guys so I have


But reading that the 3m or raybestos might be better for brakes because higher silicone content
Your thoughts

Why?

You probably already know that Silglyde is a castor oil based lube with less than 10% silicone. The Super Lube is not compatible with EPDM rubber. Teflon? It just seems like a marketing gimmick to me.

The 3M silicone is an industry standard (my opinion). Its what I use with great success. None of the controversial rubber swelling of other products such as Permatex.

There's one anecdotal opinion. Will there be more?? (Sorry for the sarcasim - I've tried many types and my best success has been with simple silicone lube.)

I was one who got burnt using Permatex purple in the past from then on I will not use Permatex products no more simply because they lie on their labeling

Thanks for info

Make sure you DO NOT use that Super Lube!

I've settled on using Silglyde, seems to work good.

I've always found it odd that EricO uses the purple permatex and has never commented on making sure to use the correct one or it will cause rubber to swell.

 

[GophersGarage]

The video I saw from Eric showed silicone paste I didn’t see him use purple maybe old video?

Count me in as one who's been burned by Permatex synthetic green causing rubber swelling. I still use it on the pad backer, but not on pins.

The thing about Sil-Glyde is that seems to be one of those products where you use it 2-3x and then the cap splits in half so you have no idea how to store it after that... I think this has happened with literally every tube that I've ever bought.

 

[rcbk00]

I switched to Sil-Glyde 2 or 3 years ago because the expensive synthetic grease I used to use definitely caused swelling of rubber parts. I bought Sil-Glyde because it's cheap and my local places stock it. I might buy a better silicone when my current tube runs out, but so far the Sil-Glyde has worked fine for me.

 

[txvwnut]

I've always just used wheel bearing grease and never have had an issue.

 

[ron350]

You should never use any products that contain mineral oil on any brake rubber unless you want it to swell.

Super Lube #21030 is a silicone grease that contains mineral oil and is not for use on brake rubber. Super Lube is supposed to sell a paste that is safe for brake rubber under part # 97008. I can’t recommend Super Lube #97008 because I have never tested the stuff.

The Raybestos brake lube with Teflon sounds good but I have not tested it on ethylene propylene so cant recommend it.

There are many products out there that claim to be safe for ethylene propylene but instead make it swell. You know Sil-Glyde works and it is safe for EP rubber brake parts.

In the old days there was a saying in the IT community: "Nobody ever got fired for buying IBM." The automotive equivalent is "Nobody ever got fired buying 3M." A can of this **** will last you the rest of your life so pay up and be done with it. Time to press the EASY button.

I can't recommend superlube for anything. Can't easily find out what's in their products so no telling what the stuff is, or isn't, compatible with.

 

[GophersGarage]

sorry guys the picture above was not me thinking to buy Superlube it was to show the Raybestos and 3m stuff for comparison.

I ended up ordering both lol Raybestos and 3m.

planning to return the Silglyde to

I use SilGlyde on all caliper boot type slides and it works perfectly, Permatex or moly only on metal parts like pads ends and backings also behind hardware to prevent pad jacking rust. I do a couple hundred brake jobs a year and when they need more pads all the parts move and nothing is stuck or rusted in place.

In high school and college we did use silglyde it’s well known I just fishing to see a better product

I will most likely use up my peramatex purple on back of pads and under clips

I used CRC 05361 Silaramic Brake System Grease on my VW last summer. It says 100% silicon.

The Raybestos could be rebadged 3M

I always try to use what the vehicle OEM recommends.

I think some of the issues with rubber components swelling might be from using aftermarket brake pads and hardware kits. Who knows what type of rubber the low priced brake part supplier is using

The other issue is exposing rubber components to brake clean.

It's good to see that everyone has their favorite though

There are factory rubber incompatibilities. The factory rubber bushing on the caliper slide pins of Nissan's will swell from the permatex purple for sure. I was looking at a car(that had only been serviced by me since brand new) I did the brakes on a month prior for an unrelated issue and noticed the slide pin was damn near stuck in the bore from swelling. Once I removed it, I cleaned the bore, replaced the rubber, and used silglyde. I didn't have to touch the brakes on that car again for 70,000 miles. Even though I've used permatex green or purple on lots of cars in the past, I ditched it for silglyde after that on anything that is in contact with rubber.

The thing about Sil-Glyde is that seems to be one of those products where you use it 2-3x and then the cap splits in half so you have no idea how to store it after that... I think this has happened with literally every tube that I've ever bought.

Get a tub instead of the tubes. I have a tub and use small paint brushes as applicators.

These are Metal-To-Metal only according to Permatex website:

https://www.permatex.com/products/l...atex-ceramic-extreme-brake-parts-lubricant-2/

Here is the Rubber safe one:

Other rubber safe versions are available from the regular parts stores:

https://www.napaonline.com/en/p/BK_7651351
https://www.napaonline.com/en/p/CRC05363

The 3M Silicone paste would be included in the last list. The 3M Silicone paste is rated for much higher temperatures than Sil-Glide so would be more of a general use product.

Don't think I've ever seen the tub in a FLAPS. Still have two tubes kicking around. Wonder if it could be stored safely in one of those little clear takeout containers that the Chinese and Indian places use?

Permatex are so full of it

Now their web site is changed to state metal to metal it was not before nor was their pictures

I have see pictures of applying to rubber parts

To many people have been burnt now they edited

Here is one I just found

The silicone version came out after the purple

But after losing trust in them I would not support to use their silicone version

n8n you can store silicone or grease in a 4-oz plastic jar like Blue-Emu comes in. You can find them new on ebay and other places.

I'd guess it would be fine. I don't think the plastic used in the actual silglyde tubs is anything special. It reminds me of the containers used for cool whip. For what it's worth, I have kept some Silglyde in a small clear plastic container that dremel cutoff wheels came in for a couple of years now and it's been fine. It holds enough to do all slide pins on a single car with a little leftover.

 

[nafterclifen]

For whatever it's worth, here is a "Tech Tips" document published by Permatex that lists their products by GOOD (green), BETTER (purple) and BEST (red) with the red being the only one that is 100% compatible with rubber. I have no personal experience, just sharing...

Get some brake cleaner to re clean the carrier bracket to remove any trace of purple

SMA uses it on everything and says hes never had a problem. Personally I've always used straight silicone paste or Toyota rubber lube.

 

[sberry]

I give up on that stuff, I been using common chassis grease on the pins and don't gob it on the rubber, thin on that stuff and havnt noticed swelling or rotting, I work on some of the same stuff a long time. Ain't worth the fuss and worry. The glyde seems to do more damage than grease.

He does great video
All I can say is I have seen now many of my brake jobs have issues with rubbers

Last job was my dads camry his boots don’t even seal to pins no more since they are so swelled up

My new method of brake job will be as follows

Purple under new hardware and non piston side of caliper
And maybe silicone or anti seize onto piston

3m/raybestos silicone onto pins

Note: I am thinking silicone or anti seize onto piston because I don’t want to chance purple getting onto the rubber of piston .

sberry, a lot of today's caliper pins have a small rubber bushing on the pin end. Putting chassis grease on that is certainly going to risk swelling it. There's plenty of internet evidence showing that certain car brake brands have issues with rubber swelling if you don't use the correct lube.

Many sources suggest using 2 different greases for brakes. One for the pins (silicone or Silglyde is my choice) and a different one for the exposed to weather metal-to-metal areas (pad ears and/or backs, caliper bracket slide areas, etc.

A very recommended metal to metal lube is the high moly paste Dow M77: https://www.boats.net/product/honda...MIr5vb7eTT5gIV7ffjBx2L4Qa8EAQYAiABEgIFJ_D_BwE

A number of us have found a less expensive alternative to the M77. It is also a high solids moly paste called PasteLub: https://goodson.com/products/bpl-2400-pastelub-brake-lubricant

This stuff has phenomenal anti wash off properties. I also use it on rotor hats, hubs, etc. to completely keep rust at bay....just paper thin coat. This works in the rust belt winter salt baths!

 

[Boilerhouse]

I bought a tube of green Permatex (product 24120) from Canadian Tire. I was told that is what the Canadian Tire mechanics use in the garage. They must do a 100 brake jobs a month. Back of the tube says suitable for entire brake assembly. Compatible with all plastics and rubbers. And now they tell a different story. I will likely chuck it out and re-do the brakes probably with the linked 3M product.

Great info Treeman. that's why many have to toss out that damping bushing because the pin won't go back in when damaged from wrong lubes.
As to hubs I am trying to find locally a spray on lube that will stay put.

I just search amazon for fun to see comments on that product you have and first 2 reviews are.

1.0 out of 5 stars Swells rubber
Reviewed in Canada on November 17, 2019
This product says it is safe on rubber, but it swells the rubber bushings on guide pins to the point where they are virtually seized. Avoid this on all rubber or rubber-looking components.

This grease gets rubber swell and cause pins stuck

I believe Permatex current system is
-green tube is general brake lube
then it goes
-purple which is ceramic
and lastly the
-red which is silicone brake lube

for me if I was to go buy silicone I would rather trust 3m/ray/silglyde

 

[MattT]

And maybe silicone or anti seize onto piston.

Check to see what base the anti sieze uses if you go that route. It may be something that'll attack some rubbers. Same applies to the moly pastes. The Dow/Honda stuff is silicon based but some others use oil.

agree in the past I was using purple on the back side on pistons and now have to think it out if that's still a good idea and just be careful applying it to piston

 

[Lassen Forge]

I've been using the same brake grease for years - black as coal, comes in a tub with a little brush, I *think* it's a sta-lube product, tho it could be NAPA's house brand as well... but it's never given me issues not headaches.

One thing about pro's vs us, is often they r&r entire assemblies, the lube they use even if it is incompatable isn't going to be an issue as the customer will be back again with a brake issue and they'll just r&r everything again. Us on the other hand tend to do piece by piece, and will notice the negative effects long term. And when you consider something like Canadian tire and most big chain places, they probably sell entire r&r's rather than just a set of pads most of the time. Food for thought.

Thanks for reminding me. SMA did the brakes on my truck last February. Now I have two vehicles that need cleaning and re-lubing!
