COLIN +PYOOR, thanks for the info, I can smell it to this day!
Around this area you cannot get TIDE either!! It will have to be
Hammerite thinners.

Has anyone tried using acetone?

I've used it for degreasing in the lab, but it's difficult to find (it's one of those compounds that have to be "licenced" 'cos it's used to synthesise street drugs). Maybe your local glassfibre stockist?

Years ago.......... I'm sure I bought a brown bottle of it from my local chemist shop....

Isn't nail polish remover mostly acetone? Well I'm pretty sure it used to be anyway (not that I'm an expert on these things!).

Yes, I think it was (erm............ I presume

)

Well, I have a bottle here (for removing occasional nail polish, but mostly permanent marker pen and the glue left by price labels!!

(Although, I usually have a more abundant supply of meths and find that works better...)) ANYWAY, I can confirm that the main ingredient of nail polish remover is acetone.
However, it also has: Ricinus Communis (which is, I assume a plant derivative); Lanolin (i.e. light-oil); Palmitate; Oleyl Alcohol; Denatonium Benzoate (That's 'Bitrex' - so no drinking it, people!!); and CI 60725 (whatever that is)

However, I'm positive I bought a little bottle of acetone for next-to-nothing from a chemist in Upper Bangor, about um, 4 years ago......

Blimey so thats what gives proper cornish pasties there flavor then El

Ah there:
Ricinus Communis is the Castor Oil plant (conditioner).
Isopropyl Palmitate is an ester of palmitic acid from coconut oil (moisturiser).
Oleyl alcohol is a non-ionic surfactant for coating keratin like a varnish.

- And what with them and the lanolin (secreted-skin-grease from sheep is what i know it as!!), I wouldn't recommend smearing nail-polish-remover on your brake drums.

p.s. I shall ignore that comment, KEVIN.

Not sure Relfy, possibly the further west you go its changes, chinese whispers, and no not everyone Kevin, certainly not you in particular, although if you've ever been to the west-country on your hols, then yes!

Just an update to say my Trav passed its re-MOT on braking efficiency yesterday. After doing lots of emergency stops on the local hill, together with judicious use of emery paper, the retardation quickly improved. More than 50% of the surface area of the brake lining is making contact with the drum surface now.

I also invested in the "Eezibleed" kit of well known name. The local engine services machine tool workshop kindly tapped the connector into the top of the spare master cylinder cap I had. I then just had to block up the tiny breather hole in the cap with Araldite and success! To think I've spent 30 years using the push-pedal method!

Thanks, folk, for the advice.

Cheers
