Am I using the right grease for brake slider pins?

[Burt Shaver]

Am I using the right grease for these slider pins? I’m just putting the summer tires in my daughter’s 09 Hyundai and I like to service the brakes at this time, make sure the sliders are sliding easy and the pads moving freely. Anyways I found this slider seized, figured I would just take it apart clean it and re grease it as usual but I found the rubber piece at the end of the pin won’t stay in place. Just wondering if this is the correct grease or if I’m using the wrong stuff causing the rubber parts to swell? This is what was recommended to me at Napa and it does does say Silicone ceramic brake lubricant so I’m thinking silicone won’t swell rubber? But not sure. Thanks for any replies

I have used the very same grease (mine came in a tube and is orange in color) on our vehicle's slide pins. I will be interested to see what others say. Is that what you had used on this vehicle's pins previously?

What you are probably experiencing is air trapped in the boot that the pin sits in.
wipe off some of that grease/lube where the seal seats on the groove.
The grease in there will form a good seal making air escape harder.
I have found that a few turns and several back-and-forth motions will get it to seat on the lip of the caliper bolt.
The lube (as far as I know will not hurt it) but the best advice is to make sure mating surfaces are clean of corrosion and a light application of lube.
Orange lube for me!

Typically I use silver anti seize. No problems so far for 20 years.

I made the same mistake a long time back when using the Permatex green ultra silicone garbage, and had the same swelling. Syl-glide has never failed for me.

I am just about finished with my jar of Permatex ceramic purple. It is really thick and sticky and I did use it on sliders and probably should not have. I decided to replace it with CRC Sylaramic, which seems better for all around use since it works on sliders and pad/caliper mating surfaces.

I would think any silicone grease would work.
In a pinch I have used dielectric grease
Girling Brake service kits has a pillow of what looks like dielectric grease for lubing pins.

This could be the issue. Definitely seen similar problems when being...overly liberal with my application of lube.

Yes, I used this previously. I got to reading the label after I had posted and it does say it’s for slider pins,

 

[Buckaroo5]

Yes, the orange silicone ceramic stuff from Permatex is what I use and it does not swell the rubber. It is also good for metal to metal contact points so you can use it to do the whole brake job. Anti-sieze is good for metal to metal but not good on the rubber parts due to swelling. Historically, Sil-Glyde has been the go to lubricant for rubber parts/pins.

Your experiencing rubber swelling. Ive had it happen with Permetex green / purple brake lube too. Now I use what Oem product is specced .
We have a lot of Toyotas, so Toyota Rubber Lube 0888701206 is used a lot. Most of the shops use KleenFlo's(?) silicone paste

 

[BillK]

Just want to add I hope you are replacing that pin ? It looks terrible

 

[BlakeTheCarGuy]

I use Sil-Glyde on the slide pins and never had a problem with it.

 

[Metallitubby]

Sta-Lube Caliper Grease if the factory/OEM orange grease is not available.

 

[Burt Shaver]

Both of the front slider pins that have the rubber collar on them ended up being seized so maybe this permatex is making the rubber swell, I ordered Sil-Glyde, I will find out next spring if it works better.

This is what you want.

Everyone that replied “Thank You” looking forward to the sil glyed coming in.

 

[Old Man Roger]

Yep, sil-gldye for the win, but the ceramic grease probably isn’t what caused the problem.

Google says.

Rubber brake parts swell when exposed to engine oil, ATF (automatic transmission fluid), or other petroleum-based fluids, which can compromise the brake system's integrity and lead to potential failure

Totally agree. That pin looks crappy. New pins only cost ~$10 (per caliper) at Autozone. New rubber accordion boots ~$5. At 16 years old I'd be replacing the boots if they are original.

 

[65ranchero]

The pins most likely got corroded by a lack of any previous cleaning and not adding any new lube.

 

[Burt Shaver]

I have replaced the boots and will order some new slider pins

The pins most likely got corroded by a lack of any previous cleaning and not adding any new lube.

I've also found the right side seems to have more corrosion than left. Probably due to winter salt more concentrated on the road shoulders.

Another Sil-Glyde user here on the pins.



I also have a bottle of this purple stuff that I use on the back of the pads and where the pad slides.

Having owned an auto repair shop for 47 years i've had plenty of experience with various brake lubes. Being in the rust belt,i found sil-glyde to wash off too easily. Delco has an excellent silicone paste that is very thick and i've used it for years on the slide pins. I would get it from my Delco parts distributership. A GM dealer might be able to order it for you also. i used CRC synthetic brake lube on the pads and brackets. Never had a problem with noise.

 

[Shadowdog500]

The only thing I ever found at the regular stores that really works on slide pins is sil-glide.

Toyota calls for “lithium soap based glycol grease” which people see to call “pink brake grease”. Which you can get in a toothpaste like tube at the dealer parts counter for half of what it sells for on Amazon. I’ve used both and this works just as well as sil-glide.

I have used a couple strands of monofilament fishing line to help break the seal on the rubber when assembling.
