So I have the stoptech drilled/slotted rotors that are supposed to be brake dust/ rust resistent but, everytime it rains or the I wash the car rust forms in the slots and holes of the rotors... it is very hard to scrumb off and remove... was hoping some of yall had better techniques for cleaning these or knew ways of somehow preventing it

thanks for anyfeedback

 

Maybe a rifle kit for cleaning.

 

Paint the rotors. Rust won't form in the holes anymore.

Take some black high temp paint, spray the face of the rotor. Take a clean rag, spray some brake cleaner on it. Wipe down the excess around the holes/slots. Take the car for a quick spin around the block which will remove the rest of the paint.

 

Rotors are not brake/rust resistant ... this is normal. Mine will instantly rust during a car wash, but they'll clean right up by themselves after driving.

 

The problem I would see here is that the degassing holes are suppose to be a certain size and a certain number if they are truely engineered for the specific vehicle. If you paint the holes you change the diameter if the paint stays in place. This in turn would change their function which is to remove gas from the surface of the rotor.

 

dont think im down for painting my rotors, but thanks for the input guys

guess ill just have to learn to live with a little rust every now and then
