The grease/lubricant thread

biko

I often get asked about grease... no I don't but here's a good guide on the various types of grease/lube you can use around the car.
Not everything you see here might apply to your car/case.

I've seen aerosol cans of Silicone grease for €1 around. Is this the right stuff to be spraying on all my rubber bushes on the front end for a bit of preventative maintenance?

biko

Yeah silicone is fine on those.

I tried a few motor factors..( Halfords & dicksons) in Cork looking for some dielectric silicone grease for my Saab 95s DIC but no one seems to stock it or even know what I'm asking for.
Anyone know of a seller in the Cork area?
Thanks !

I don't really think silicone grease is available in any ordinary shop here in Ireland. That's why I bought off ebay.

CJhaughey

Any place that deals with O-rings should have it, electronic shops Maplins should have it over in the BP shopping centre.

Hi Guys,

I have ordered a few bits to repair the rear brake caliper in my car and I have a question - where I can get a grease for the slide pins? I asked in the local motor factor, but with no success. Looks like they have no idea what I am talking about.

Any advice will be appreciated.

Had they any red rubber grease?

No. Just the Copper Grease and a "Normal Grease" as they said.

Don't use the copper grease anyway even though alot of people do. Copper grease is anti sieze compound not a lubricant.

When I was looking for the same I emailed Mintex about their ceratec. Asking was it suitable for the slide pins, including ones with rubber bushings. They said it was.

I used it (a few months ago) and it seemed very sticky to me. I haven't taken out the slide pins since to check them.

landmarkjohn

I'm not a mechanic but I use sparingly Castrol LM, a high melting point grease on the slider pins..... had it for donkeys years..don't know if still available under that name.

I have read about "silicone grease" for this purpose.

I think a scrape of the copper grease on the back of the pad is a common practice to prevent squeel but modern pads don't seem to suffer as much.

You need to use silcone paste/grease on the slide pins.

Copper grease will cause the rubber to perish.

I have a bucket of copper grease. I would not use it obviously due to the above .

The grease on MicksGarage looks good, but I would need it for tomorrow, so would love to source it locally.

debabyjesus

Go to biggred.co.uk or to their ebay site and get some, just search slider grease on ebay. They used to send it in little tins but now they have little sachets. 1 satchet is enough for 2 calipers maybe a bit more, handy as you can order a few satchets and use as required. Motor factors just look at you like your mad for wanting fancy dan grease and can't fathom why you don't want to use copper grease on sliders, sure all the taxi men use copper grease buuuuddddd

Thanks for all suggestions, and just one more thing came to mind. I have found a sachet of some CV joint grease in my garage. I know it has its purpose, but it works in the rubber booth, so should be safe for the brake pin booth rubber also, which I am replacing tomorrow at a huge cost (main dealer prices). Until I get the right grease, would this grease be OK?

nd

That's what johnboy said he uses and "he's never had a problem with it"

CJhaughey

I have a feeling that the rubber in the brake sliders and CV joints is not the same stuff, CV joint rubber is much more like polyurethane not natural rubber like the brake slider rubber.
I may be wrong but I didn't take the chance, I bought a 500g tub of the red rubber grease from Ebay. Cost about 16 delivered.
Probably enough for the rest of my lifetime.
The thing with red rubber grease is that it can be used in contact with Brake fluid as well, lubricating the brake seals inside the caliper as well.
Not sure if silicone grease is able to be used in that situation, probably a no-no if you are running DOT 5 as it may react.

Thanks CJ, makes sense. I wish you were based somewhere near me, so I could borrow some of your grease tomorrow, if that is not too much to ask ? Otherwise I will order the stuff from eBay or Mick's.

Thanks CJ, a good bit away so.

I wonder what the main dealer's mechanics use for this kind of job?
Ah, sure, never thought... They would replace the caliper with a new one if there was a problem...

Wow, a bit steep. You should have tried another motor factors. I usually go around to a few. Each one has their own good selection of products.

CJhaughey

Is there any electrical wholesalers near you? They should carry silicone grease for electrical work, sometimes Plumbers have carry it as well.

Tony Beetroot

Are you near a halfords op?

Red rubber grease is not that common, even in good MF's they don't seem to carry it.
Mail order is handy enough, for some things I could be traipsing around for a few hours looking in MFs and getting blank stares.

Yes, we have them nearby.

Tony Beetroot

They should have the silicone grease anyway, might even have the red rubber grease. Try them and give an update later.

OK, I will actually. However, I have checked their website, but didn't see anything like it.

Seweryn

OK, so I have an update already... My OH collected the new slide pin and the rubber boot for the brake caliper from the dealer today, and received a sachet of grease as she asked for. Was told this this is not a copper grease or any multipurpose grease, just the right stuff for the job. I hope to get my hands dirty this evening on the task, so will see what it is.

Thanks again for your advise.

Interslice

Been using this the last week or two. Penetration into rusty bolts and other seized parts is amazing. Seems to do in 30 seconds what wd40 does overnight.

Where did you pick it up interslice what the cost?

My mate imports into work from the north. 3 quid a can. Haven't seen it in any motor factors here yet.

Have it here in caufields. http://www.caulfieldindustrial.com/citec-pocket-rocket-lubricating-spray/p-226239pd.html


Plusgas is supposed to be good to, haven't used it.

I couldn't really see any definitive answer here, so was wondering if anyone else had suggestions?

I've been having trouble with the rear brakes on my '12 Prius, and turns out one of the guide pins was completely seized. Toyota seem to suggest "lithium soap grease" though I'm not entirely sure of the specs - is that pretty much what the generic "multipurpose grease" from the likes of Comma and Carlube is? The Comma stuff claims to be good up to 120 degrees C - is that good enough for brake-related items? I ordered some Mintex Cera Tec which seems to be lube specific for brakes (incl. guide pins), will see how it goes. Whatever grease Toyota had was over €30 so I didn't bother with that (new pin was only €9!).

For any other hybrid/EV owners (with rear disc brakes): Definitely worth inspecting your rear guide pins at least every 2 years or so as the rear brakes get used so infrequently and they are well known to cause trouble if ignored, especially in areas where roads are salted a lot.

Red rubber grease not copper grease what 99.98% use.

zilog_jones, I moved your post to a newer thread that deals specifically with grease
