Is this safe for caliper slide pins?

[Rust_Belt_Pete]

I still have my 15-16 year old tube of silaramic silicone grease. It has some solids added to it for anti galling and sliding properties.

Whatever the choice, one would do well to remember the slide pins are maintenance items and should be regularly pulled, cleaned, and re-greased (especially in certain climates/environments). Too many folks either perform a one-and-done service or neglect them altogether.

Most pins take literally one minute each to service; I do mine once a year during tire rotations.

Silicone paste of many listed.

Wheel bearing and CRC synthetic caliper grease made the pin boots on my Sequoia swell and cause issues. Since then I tried Syl glide bu that got very watery. I have the Delco paste, still some Permatex Silcone paste and a bottle of the linked ones from @Trav recommendations. No issues since switching to the silicone paste.

I just use wheel bearing grease on mine, never a problem

Eventually collects too much dust and dirt which makes me worry about silicon paste. I just leave mine dry.

Wording and marketing is the issue. We have caliper pad grease, grease for ears of the pads, for reducing noise and for sliding pins.
Use the one that is for sliding pins, if it says "brake grease" doesnt mean that it is meant for caliper pins.

Probably works for where you are. But for those north of the mason dixon line, salted roads, and moisture, that might not work so well.

What did you do to your sunroof? My RAM has been leaking for a while now.

Sunroofs aren't designed to seal. They have a drip tray around all 4 sides, then that water is directed to drain hoses located at each corner.
If a sunroof leaks it's usually because one of the drain hoses is blocked, not allowing the water to drain away.

Galling will happen regardless of weather. Just a different way to be forced to repalce caliper pins and brackets

I know but all hoses are working and the tray is overflowing. Ive adjusted and cleaned everything yet it still leaks like its open. I'm about to silicon it shut.

From my personal experience, the AGS Sil-Glyde failed and seized up one of my slide pins on a ‘03 Corolla. Surprisingly it was NOT the pin with the rubber bushing but the opposite solid pin. The boot was undamaged and intact too so no salt or water intrusion. The other caliper also exhibited signs of seizing but luckily could separate. Took 1.5hrs of repeated soaking, heating, twisting, impacting until it finally released with the destroyed pin as collateral. I’m sure Sil-Glyde works if you regularly service them annually but I mistakenly didn’t look at them for about 3 years. I have a ‘15 Toyota Sienna with all original brakes with 65K and only inspected just recently and no issues with slide pins. I am swapping over to the Toyota grease for the caliper pins moving foward. P/N 08887-01206

Always used syl glide and never had problems.

I have been using that Toyota Rubber Grease with no issues but I would recommend annual or every other year where you verify and check the slide pins move freely to prevent being in the above scenario again but thank you for sharing your experience.

 

[nthach]

Sil-Glyde, Toyota Rubber Grease or Dow 111 is all I would use on slide pins.

 

[Drifter]

I use the Mission stuff with no issues. Bummer its no longer available. I really like it. Still have about half a bottle left.

It's a mediocre product that's mostly castor oil. Despite the name, it contains little silicone, if any at all.

Castrol GTX was a fine oil in 1979. But things have advanced since then.

Hey!
I'm wondering if WD-40 Specialist Silicone lubricant is appropriate for caliper slide pins.
ChatGPT suggested that silicone-based lubricants are ideal for this application, which is why I'm considering this product. However, I want to double-check with real-world experience.
Thanks!

What do you think @Astro14 ?

Prepare for rant fellas


But no, I would not use such a spray lube on slidey pins, I would use a grease or antiseize.....I dont think that juice has enough stickinization.

I used string trimmer line to clear mine when I had a sun roof.

I used to live in the rust belt. And in that case whether you use grease or not it requires annual removal and cleaning.

Yeah the spray can is way too thin. If you're not a frequent brake repair guy you can buy single use packets of the right stuff at the counter of your parts store.

I use the little packets as the brake caliper one at Autozone is Sil-Glyde. Don't use it often enough so good enough.
