ok so i just installed these rotors 2 days ago. now it just started to rain today and when i came out the car i looked at the rotor[crossed drilled slotted] theres rust arond the hub part. what im i suppose to do? keep cleaning it with wd 40 after it rains??

 

Too much WD-40 may guarenttee you a good rear ending on someone. My rotors were zinc dipped and to date have not rusted once...

 

thats why you purchase the ones that are zinc plated.

 

aaah crap. but is there anything esle i can do??

 

The zinc plating only lasts so long. After several thousand miles of use, they will have a light coat on them. I just replace them every 30K and not worry about it.

 

but its only been 2days!!!

 

If it just rained and there is rust, the rotors are fine. It is just a thin layer of surface rust and it will go away as you drive. Nothing to worry about.

 

The part that touches the pad will be cleaned as you drive by the brakes. The hub will continue to rust. I had my zinc plated rotors turned and it took all the zinc plating off the hub. I just painted the hub part with high temperature caliper paint. There are tons of brands out there but make sure you use something that says it's designed for brakes, calipers, and drums (they get hotter than the regular high temp paints get). If they're starting to rust, sand them then paint them and you shouldn't have anything to worry about.

 

he's talking about on the hub area, not the friction surface.

for rust on the hub area, you can clean it up and hit them with high temp black (or whatever color) paint, or powdercoat them.
either that or send them to a zinc plater and have them plated.

the high temp black paint is what I do on them for quick and dirty jobs, but powdercoating will last longer.. (but most people don't have a powdercoater in their garage like I do. )

 

hhm so paint them... dam

 

My plated x-drilled brembo's have over 50,000 miles on them, and have been on the car for over 3 years. They show no signs of rust ever on the hub area and stop as smooth as silk.

By far they are the best "mod" I ever baught for my car.

 

Where did you get the rotors from?

My tirerack REAL brembo X-drilled rotors have never rusted.

 

Same here...I got over 2 years and almost 40,000 miles on mine and no rust at all. I only get a little surface rust on the friction surface (the part that had the zinc coting worn off) after I wash the car or it rains all night, but it's gone after I use the brakes for the first time.

 

last i checked Brembo only makes either drilled OR slotted not the combo of both! looks like you dont have Brembos on there...

Ant

 

brembo has blanks and does sell them. my old 96 had them. and yes they were brembo... fact i still think i have a box here some ware in my attic

 

take a brembo blank...slap it on a drill machine...shoot some holes...grind some slots...WHAMM-MO! Brembo drilled and slotted rotors.

FYI...brembo doesn't really endorses this use/machining of their blank rotors.

FYI2...majority of the Brembo rotors that are drilled and/or slotted fall under the above category unless you're rocking their ubber $$$ big brake kit.
