Hydraulic disc cleaning

Muahahaha

Just wondering what you should use to clean brake discs? Mine are developing a bit of rust in parts and I dont want it to get out of hand. Theres probably so expensive stuff available marketed specifically for bike brake discs but I'm wondering would rubbing alcohol do the trick? If so where is it usually available- a pharmacy or a motor factors?

Recently asked the LBS about this and they told me to swerve the specific cleaners and buy a bottle of surgical spirits from the chemist down the road. Works like a charm.

Muahahaha

Nice one thanks for that. I was looking at the brake disc specific cleaners and they were all around €15 which seemed a bit OTT. Will get some surgical spirits tomorrow and get it them back to a decent condition, thanks again=)

What he said ^^ isopropyl from the pharmacy on a rag, or go to a motorfactor and get a can of brake and clutch/ carb cleaner, does the same job only it is in an aerosol.

Brake discs shouldn't get rusty though, they're stainless, to clean them I'd be taking them off the bike and using a small bit of emery paper on it

Why are they getting rusty?... My bicycle disks have never rusted however my motorbike's disks have but then I cycle more than I ride the motorbike~ so, are you leaving it outdoors for a bit between riding?.

Outside of that, what the other lads have said.

You're obviously not getting enough heat into them discs. Try harder!

Stainless steel still rusts, just not as easily as regular steel. I imagine that your disk breaks are made from a more basic alloy and are more susceptible to corrosion. It shouldn't be too difficult to clean with the advice fromt he previous posters.

Are they stock breaks or did you buy them separately? I have two sets of disk breaks and both are in great nick. The original set is about 5 years old at this stage.

Muahahaha

This is them, the actual rounded disc appears ok, its more so the metal spokes inside it that are rusting slightly. They're stock discs on a Boardman Pro, the bike is always stored indoors but I'm not great at wiping it dry after being caught in the rain so I guess thats why they've become like they are. Sounds like the surgical spirits should remove it, glad I asked here before I did something stupid like put wd40 on them Thanks again

tbh I wouldn't be worried.

Looks like cheap metal.. When I replaced the disks on my R1100S with Hong Kong imports I got the very same problem but the braking surface was free of rust spotting, I've never had this problem with OE parts/disks on any of my motorbikes.
