Rust on brake discs

[Chris100]

Hey all,

Has anyone recommendations to stop rust forming on the brake discs after washing?

Its really annoying having this when the rest of the car is nice and clean. Its even more noticeable as the car doesn’t get driven for 4 or 5 days at a time at the moment.

Wd40 seems to work when I do mine.

Bilt Hamber Atom Mac, Motor sports and spares and Blok51 keep it. Or just blow dry them

Yep this is what I use too, works a treat, also the ratio to make it up is so small- the wee bottle would last for years

Dry wheels then spray this onto discs , drive the car back n forward a couple times and they don’t rust.

@Nigelo recommended a quick spray before you wash too, so that’s what I do, not sure if necessary or not, but like you said, it’s well diluted!

 

[Snoopcousins]

Will try that then too!

Drive it

Just drive it back and forward several times working the brakes all the time. That seems to be what Jim White (detailer) does.

Drive it

Not really sensible if washing to cover, wax or polish though, wash, dry and get it inside ASAP so no crap settles on it!

If your taking it inside just drag the break with your left foot as you drive in.

I haven’t touch dried a car for years, blow dry and get it inside and covered = no swirls, getting water off the discs takes about 5 seconds per wheel, mostly I just rinse with filtered water and let dry though.
Odd....yes
****s given....none

Sounds like the polar opposite of Zero ****s.

I'm sure the next person to own the car will appreciate all your efforts, as they go out of the junction at the end of your road, sideways on the limiter!

Then drop it off at Romanian car wash for a sandpaper

Sideways is my job, and it’s no ****s given for being odd
As a bonus I don’t have neighbours to see my antics

@MarkM

do you wash this atom stuff off? Or is it something you spray on and leave after the wheels have been rinsed?

This is top tier RMS right here

Yes just leave it

I normally give them a spray at the end of drying the car, then drive it back and forward a few times - find the brakes spreads it into the discs well/ if I don’t do this you get black liquid drops coming off the discs onto bottom of your rims

Here's me thinking @Todd was in a league of his own for changing perfectly good brake discs because the bell's were slighty rusted!

Brake discs are as cosmetics as they are mechanical lol!

No point having nice, clean wheels with a tatty looking disc behind it!

I also find if you leave that wee layer of rust on discs that it flakes off when it’s dried and driving around- gives a crappy brown coating on your rims - this is the main reason I try to keep it off

Only if the car has been literally lying out for months.

Water staining from washing and reversing a car indoors, doesn't really transfer to the wheels.
