Ha ha, funny you should quote ACF-50 as I was the UK distributor for many a year (And with a considerable amount of technical involvement) and have used it ever since. Although primarily designed for the Aviation industry I introduced it to many a different market especially motorcycling. You will find that ACF-50 albeit thin film is far more of a lubricant than WD40. In fact when I mentioned the tests I was conducting earlier in this thread it was with this product Vs WD40. ACF-50 is fantastic but a longer lived product when applied and with a higher lubricity by far and def not one to get on brakes.
Perhaps not so misguided shrugg

Its a certainty that if you ask a loaded question ,should i put a lubricant on my brakes, no company will commit themselves to say yes.
I am not sure that Lisa in customer support could say any different.Her reply to use ACF -50 shows her knowledge is sadly lacking.
Ian has spent a lot of effort in saying what is WD 40 and its make up.
Its not a lubricant and it will evaporate . The person is putting this on his own brakes and will assess the risk to him.I think its minimal over the time scale of a winter.
There are other products that can be used if you Google for them.
Water is a lubricant for brakes but it is soon removed.

I agree with Jaytee, I use ACF-50 on all five of my motorcycles, an excellent product, but I certainly wouldn't use it near my brakes! I can't believe Lisa suggested it. Neither would I use WD40 if I was using the vehicle, bike or van, next day, week, or even month. However a winter lay up is a whole different thing. I will report next spring..

I said: "...my advice would be never to introduce any type of lubricant (exact formulation known, or otherwise) to friction materials."

Lisa said: "...I have spoken to our Technical Team and we wouldn’t recommend this. They have suggested an alternative product, ACF50..."


Please don't put words in our mouths, folks.



I can no longer be bottomed with this thread.

Pete......you are an experienced person with many years in the 'trade', such as myself.
You and I are well versed with the expression 'a little knowledge is dangerous'

We can only advise and put our concerns across.

For those who wish to spray whatever they like onto their brake discs, 
(eg. hairspray  hugegrins ) then that's for them to take the consequences.

Sometimes it's just not worth bothering!

I introduced the 'hairspray' idea fron a serious VW forum. Surely we all know even without engineering expert knowledge that rust requires air and moisture. Hairspray would seal out both and the film so thin that it would disappear on the first application of the brakes. I see no reason why it shouldn't work but of course I'm no expert.

Glad to hear everything went well with the new knee. The timing on your post suggests that the bio-clock still needs time to get back in sync smile!

Well, as promised, an update in spring.
Before going to NZ at the beginning of December I went ahead and sprayed my front discs with WD40 while spinning the wheels.
On my return 3 months later there was only very light rust on the discs, so today I set off on the van's first run of the year, 20 miles, no reduction at all in braking effect. Everything is now nice and shiny, unlike the previous year when the pads rusting against the discs had caused the whole lot to be junked. This will now be part of my annual lay up procedure.

Thanks for that Al.

Have to say it goes against all logic, but an easy remedy if it works. I still don't think I would want to do it unless the van was going to be unused for a while - long enough for the volatiles to evaporate off????
Just bought a bumper tin of WD40 as it happens! up!
