Grease on brake pads?

[texadelphia]

Do you guys put grease on the back of your brake pads where they contact the caliper and the piston? Watched a couple youtube vids and it doesn't look like people do that on the B7s. Is there some reason not to?

[Flygman]

Yes. I lubricate all metal-to-metal surfaces (except brake rotor to hub and rotor to wheel).

[gotrek]

Yes as well. All pins and sliders get lubed and the back of the pads.

[griga]

I only did it because my Hawk pads came with some so I figured why not

Ditto. Use the lube that comes with the pads or CRC Disc Brake Quiet (has done a nice job with our B7).

I use lithium grease on the slide pins and copper anti-seize on all contacts (metal on metal). Love this product:

CRC brake quiet on the backs of the pads. I don’t normally lube anything but the slide pins but maybe I should since I’ve noticed a rattle down there on occasion. Might check out that loctite copper anti-seize.

[texadelphia]

Two packets of lube came with my pads so I'll use that on all the sliding surfaces and the back of the pads. Also bought some permatex caliper grease if there isn't enough in the packet for the slide pins. I also have a jar of permatex copper anti-seize to put on the hub behind the rotors.

yes I do but do NOT mix greases. if you have to use them in separate locations.

Believe it or not after over 40 years of wrenching cars and brakes I find the best stuff for brakes is Sil Glide ..

Found out about it when I was doing the rebuild on my sons Bonnieville. A must have now in my toolbox.

I definitely wouldn't mix them and I'd prefer just to use only what came with the pads, especially since the paperwork says they won't warranty them unless you use the grease they supply, but it's such a small little packet.

You should be using urea grease on the slide pins. Not lithium grease.

I use Permatex Ceramic Extreme Brake Parts Lubricant if CRC is not available.

[beefski]

Slides and contact points a must.

[gotrek]

Careful with antiseize. It will be fine on pads but I would not use it on slides and pins. Antiseize uses softer metals to stop galling by creating a wear layer but on moving parts it can eventually form a chemical bond fusing different metals together when the grease in it dries.

So I was just looking at elsawin and the instructions indicate that you should lube the pad and spring clip guide surfaces with polycarbamide grease, but it doesn't say anything about lubricating the guide pins.

[Charles.waite]

When you’re servicing the calipers you should absolutely grease the slide pins with caliper grease. Unless you want them to rust together and cause the calipers to fail.

Elsawin probably doesn’t show it because it’s not strictly necessary when replacing the pads and rotors. But it’s smart to clean and relive the slide pins regardless. When I’ve cleaned up older calipers the slide pin grease is always super nasty.

I use Permatex Ultra Disc Brake Caliper Lube and it’s always served me well for the slide pins.

[texadelphia]

Reading some mixed reviews about the permatex stuff. A lot of people seem to have issues with the rubber boots swelling and binding up the pins with the Permatex. I think I'll try to track down some Sil-glyde for the pins and use what came with the pads for everything else.

[beefski]

Sil-glyde for slides and all contact points. High heat and moisture resistant

I used the permatex green on my current brakes when I did them about 5 years ago. I’m replacing them soon with S4 parts so I’ll report on how the green stuff has held up. I would expect just fine given how I’ve really had zero issues with them since I serviced them. Just sick of my garbage store-brand rotors getting gummed up with deposits and faintly pulsing through the pedal. And I can’t pass up an opportunity to upgrade to S4 brakes.

Btw I used the same can of permatex green on my b6’s S4 brakes almost 7 years ago that, as far as I know, are still working just fine.

This is what we used at Acura when i was a tech there a few years ago. Great stuff.

If I could find urea grease locally, I'd definitely use that as that's what the workshop manual calls for.

No local Honda dealer?

I read somewhere that Honda dealers don't sell it. Guess I'll confirm with a phone call.

[texadelphia]

Turns out the internet lied to me. $20 at my local dealer.

[texadelphia]

I think I'm going with sil-glyde on the pins. The interwebs seem pretty unanimous on it working well and elsawin doesn't specify. Just going to get a bottle brush and clean out the the pin holes really well to prevent mixing it with whatever was used on my car in the past.

Try Acura, maybe sell it cheaper? Who knows.

Not really concerned with cost. Just want to use the best thing. As far as I can tell the reason polyurea is used is due to its high temp resistance. Sil-glyde seems to have similar high temp resistance and a lot of people say that it works well. Plus I have 4 packets of it and the Honda dealer is a 45 minute drive. I'm not sure how well either helps with corrosion prevention, but there are a lot of testimonials out there backing sil-glyde.

Yeah its definitely good stuff the urea grease. It'll handle whatever temp you throw at it im sure. I use it on my rear brakes with no issues at all. My slide pins move with ease.

Realistically, any of these greases is going to provide roughly the same lubrication and likely corrosion prevention properties. I’m still perfectly happy with the permatex stuff unless I pull my brakes off and they have swollen boots in which case I’ll try the sil-glide

yup I used Permatex on my sons car becasue I ran out of my syl glide... was awesome glue... glued the pin in the carrier in just over a year.

they do have different grades .. I can tell you the stuff in the green container is absolute crap...

https://www.permatex.com/tech-tips/g...st-brake-lube/

I wont use any of it anymore after using sil glide but I understand ymmv

[Charles.waite]

In your experience I suppose. In my exprience it works just fine across 3 different cars (B6, B7, Q5). So does that mean my anecdotal evidence cancels out yours?? haha.

But seriously, I'm not saying its the best, simple saying I've had good experiences with it. The Sil-Glide stuff sounds legit but since I already have my Permatex and its not let me down, I'll continue using it I guess.

Although, I'm starting to mull over a 345mm Q5 front upgrade (fixed calipers FTW) so I'll likely not need it for those I guess...

Edit: on the other hand, their ceramic greases definitely sound better. So, yea maybe don't bother with the green stuff unless you're on a budget. I don't think I saw the red or blue stuff when I got mine forever ago (2010 maybe?). Might be time to upgrade my grease after all, now that I'm realizing my jar is nearly a decade old. Damnit Iceman, you badgered me into buying more stuff!

Also the second page of the PDF linked on that Permatex page is actually pretty concise and helpful in describing where to apply grease to caliper parts: https://441py33rout1ptjxn2lupv31-wpe...PS-FLYR-V4.pdf

[texadelphia]

It's crazy how there doesn't seem to be a straightforward answer for this. I'd think that VAG would have a definite specification on what to use.

ETKA lists Lithium Grease on the page with calipers, pads and rotors, FWIW.

[texadelphia]

Oh nice. I don't have access to Etka. Good to know though.

ELSAWIN states to use this stuff:



Polycarbamide is Polyurea. So molykote or something should be what the factory specified.

[texadelphia]

Item 1 (item 11 in my elsawin) in the accompanying diagram points just to the pads. "Pad guide surfaces" just sounds like the caliper/pad contact points, not the pins.

For item 16 in the figure in that section, which are the guide pins, it just says "Guide pins, 30 Nm". No mention of lubrication.

[Charles.waite]

Yea I noticed no specific mention of lubing the pins. Obviously you need to, as there’s lube in there from the factory but no mention of what kind. I’d be inclined you use that same urea grease if you have some. That Honda stuff is probably better and cheaper than the VAG stuff.

I know the stuff I’ve scraped out is grey, and a tad sticky. Not sure if it’s grey from wear or age but it is, FWIW.
