Are you serious?

[Exige77]

Exposed steel will rust.

Brake discs are (mostly) made from cast iron, so they're always going to rust where the pad isn't in contact. All you can you to stop it is to rub them down with sandpaper and put some high temperature paint on them.

really?

what do you expect to happen to bare metal?

[Cardinal Hips]

Love it. That's really tickled me, thanks for the giggles OP. 10/10

The surface of the disc is always going to rust. You could paint the bell if you want it to look prettier.

Should this really happen a week after getting them put on? I'm looking at family members brake discs and they don't have the same amount of rust. The garage did remove some rust I think and they didn't seem to clean it out correctly. So it looks like the rust from the other parts has got onto the discs when it rained.

Edit: They were rust free until it rained.

It might have been a hoax ?

Try WD 40

We need to have a PH member cull. First someone doesn't know the difference between a Spitfire and a Hurricane and now this???

They obviously need oiling!

I found a nice white grease, in copious amounts did the trick for mine.

OP, you can buy tyre covers to fit over the tread, sort of like snow chains do. To prevent your tyres from wearing out in contact with the road. I'm told fitting brake pads the wrong way round also prevents the friction material from wearing.

[Cardinal Hips]

You need to paint the entire brake assembly to stop the rust.
Like this:

[GAjon]

Brake discs do this.

What you need is break discs, they don’t rust.

[hooblah]

Scrub it with a scouring pad to remove the spots, then apply copper grease to cover the whole disc. This should prevent it from happening again.

[nosuchuser]

WD40 will keep the rust off if it's that big a deal OP.

[MDMA .]

Take the wheels off, light rub down of the hub, couple of coats of spray zinc. That or buy some better quality discs that have the rust resistant coating already applied. EBC Ultimax, Vagbremtechnic to name a couple. Had them before. They never rust.

It does look unsightly, see new cars on forecourts with brake disks that look like bits of the Titanic.

The braking surface has no chance, someone said its the type of steel they use nowadays, older ones didnt seem to suffer as badly but not sure of the specifics.

It doesnt affect braking performance, but if it bothers you, whip the wheel off and clean the centre bell with brake cleaner and give it a coat of VHT paint, dont worry about getting a bit on the braking surface as the first time you press the brakes it will be scrubbed off. It doesnt last forever but once its done its easy to give it a quick coat when you have a wheel off.

Jeez, you guys. Look at the OP's name.
