I enjoy washing my car, but I hate wet washing my wheels, because if the braking system when it get very wet it is annoying to dry them, the front ones is the worst.
I usually wet wipe my wheels, so that I do not get my disc rotor and brake pad wet.

If did get them wet, I blow dry with compressed air and usually take few rounds around my housing area to dry the brake.

When I failed to dry the brake pad by driving around my house area with brake pedal mild touch on disc rotor, below will happen.
This is simply a 12+ hours duration. Wash the car at night 5PM to 7PM, the next day mid noon below is what I get.







Using green scotch-brite pad can only clean it so much





Its my maintenance drill that when I am about to leave my car for long holiday ( I am flying to Bali ) say 3+ weeks, it has to be washed clean and covered up.
Battery charging once per week will be handled by my male servant, no worry.


I was also cleaning every damn cooling holes on the front disc rotor, as when and if they rust and creating micro high spot, it will attack the brake pad and long term
you will see disc rotor un-even grooves like below : My old set


I have replaced my FRONT disc rotors ( photo above ) in 2021 at 34,000 KM, now I am at close to 43,000 KM so 9,000 KM old front rotors today..


.

I want to keep disc rotor as smooth as possible till its end of service life. Now it is smooth. Last month October photo archive at 9,000KM of use.





I recalled long time ago when after car washing, wheels all wet, me did not drive around the housing area to dry the brake system, the car then only get to be used the next week or 7 days,
the blo-ody front brake pad will get so stuck on the disc rotor ( by rust ), the sound it made when breaking free of the rusty grip is LOUD, CLANK !!!


Now I want to avoid any such rust formation from brake bad to disc rotor. Keep my brake system be very well behaved longer.
The drilled vent holes itself is a maintenance nightmare already, because I have to blow clean them every like 2,000KM, or else rust formation on them will ruin the brake pad surface
and eventually the disc rotor smooth surface will get un-even contact from such brake pad.

I wear a chemical mask from 3M. when doing the brake disc rotor vent holes cleaning.


If the disc rotor is super smooth, the brake pad is then good too.
You will never get any sort of vibration even when hot ,,,,from a smooth front rotors. It will be a super smooth braking system when pushed hard.
That is my performance target for this 2nd front rotor set of mine.

Lesson learnt from 1st rotor ruined, was also ruined by track use 20 laps though.

So, when wet wheel washing, do dry them properly guys.

 

A product called Hydes Rustopper may be of interest to you.

 

Thanks Steve, I can't get that in my country

 

If it contains a food additive, we may end up in the same situation.

 

Nice! In my house, I'm the male servant...

 

 

You might consider WD40, especially if the car will set for awhile after washing. WD stands for Water Displacing. 40 is the 40th attempt to develop the fluid. WD40 will displace any water, dry in a few minutes, and leave a thin film of oil, which will also dissipate. You have to remember to ride your brakes from the minute you put your car into gear next, until you can tell that the last remaining oil is burned off.

 

I had never thought of it (WD40) but I think it can use it to cure for brake squealing issue as well
Thanks

 

Wont it make my brake pad + disc rotor be kinda "oily" ?
Disc rotor has no pores, but the brake pad friction material has pores as such it retain water too hence the rust I am getting is actually the transfer from brake pad....
like manual tranny clutch when wading in deep water I guess.

 

do not use wd40. besides leaving a potentially hazardous residue on your brakes, wd 40 is a toxic solvent and leaves a long lasting unpleasant odor which 'may' intrude into your vehicle.

 

I like the scent of WD40....

Better than EAU de Diesel.

 

Good thing it never rains where you are.

 

wd40 is mostly diesel oil.

 

Hmmmm, it must be why it makes my hands very greasy lol
Gooey stuff is what I abhor but it is likely why it is a cure for many things as well . Well, I wear gloves when I use it as well

 

fwiw this is what i found.

"Based on the provided search results, here is a summary of the main ingredients in WD-40:
According to the US Material Safety Data Sheet (MSDS), the main ingredients are:
Aliphatic Hydrocarbon (45-50%): a mixture of mineral spirits (primarily hexane) and other petroleum-based solvents.
Petroleum Base Oil (LVP Aliphatic Hydrocarbon) (12-18%): a light lubricating oil.
Carbon Dioxide (2-3%): a propellant gas.
Surfactant (Proprietary, <2%): a surface-active agent.
Non-Hazardous Ingredients (Mixture, <10%): a blend of other additives.
The MSDS does not mention fish oil or any other biological ingredients as components of WD-40.
Some online sources and forums may claim that WD-40 contains fish oil or other unconventional ingredients, but these claims are likely urban legends or misinformation.
A 2009 article from Wired magazine analyzed the composition of WD-40 and found that it primarily consists of mineral oil, decane (a type of hydrocarbon), and other petroleum-based solvents."
