Rust again... now a brake contamination problem... :(

Whytepeak

Despite my best efforts to patch up my frame against cable rub, I noticed that the cables rub on the top tube aswell as the headtube. :roll:

Now there are two areas of tube where the paint has been replaced by rust - steel frame.

Should I just 'clean the wounds' and stick some lizard skins patches over the bare metal, or have I left it too late...?

Thanks.

Yeah, just clean up and patch. Use copter tape then you can see what is going on under.

Personally, the closest colour match in a car touch up pen to seal it from the elements, then use a protector of some sort.

If you leave the rust exposed, it is likely to spread and get under the paint around it.

Thanks Supersonic.

Well I've sprayed all the internals with GT85, (whilst messing around fitting a new stem I round the frame to be a bit damp).

But whilst I was spraying, the small plastic hose thing came off the spray head, resulting in me spraying it right onto the brake pads. - The wheel was not on at the time...

Are the pads messed up, or can I fix them with some muc off brake cleaner stuff?

Sorry for being incompetent :roll:

It usually kills them. But cleaning them and using sometimes makes them a bit better.

Whytepeak

Ok thanks supersonic.

I contaminated my pads but managed to fix them......
I used a gas blowtorch tip and put the flame on the pad faces for several seconds, afterwards I roughed up the pads with a file and they have been fine ever since.
It is possible to burn the contaminant out of the pads, some people here have baked there pads in the oven for half hour lol

Whytepeak

Yeah, I'll try and fix them, its only the rear brake anyhoo.

- You're saying I should put them on the fire? :shock:

and most people tend to burn off the glue and dont realise until the brake friction material falls off.

get new ones.

and do not use spray lubes about the bike.

Sorry to highjack the thread, but judging by the title my question is relevant.

I recently brought some Goodridge pads for my Hope Mini Monos, as usual with bike parts the tolerances were rubbish and the pads didn't quite fit in enough to get the pin through - I had to file a little bit of the edge of the metal on the pads to get it to fit, the pads work great so far, but stripping them down the other day I noticed there's a lot of rust where I have filed away the copper coloured coating on the metal (not surprising for something that gets hot and wet). Should I be worried?

This is true and you gotta be carefull but then if there knackered anyway its worth a go I reckon, the worst case is you gotta replace them.

Mine have been fine but that might just be down to the make of pads I use.

Good old WD40 will keep the rust at bay

Maybe you could try a dab of metal paint on the exposed metal. But then again I don't know if it'll handle the heat and contaminate the pads?

surely the worst case is they fail to stop you because they have fallen apart and you smack into a tree / go off the edge of a cliff? :shock:

You may have a point there lol
Well im still alive so far.....if you skint like me then its worth a go in my opinion.
If my pads did fall apart, (assuming I survive) I would replace them, but at the moment they have done 60miles no problem and saved me 15quid which im now gonna have to spend getting my wheels true'd.

but thats just me..... 8)

whatabout that high temp engine paint for the pads?
