yes - that is correct, it's also not mentioned in my post as the reason for my car having zinc plated rotors, and the OP brake disks are obviously does not. This is not about materials, it is about rust inhibition that obviously in the case of my Trailblazer has done an excellent job in prevention surface rust.

 

Must confess I have never heard of zinc plated rotors...

Your rotors are zinc plated by Chevrolet or something you did ?

They are the original disks, I never touched them. Zinc plating is (was?) very common.

My 2018 Benz has zinc plated disks, too.

Yeah I can understand a high end  or performance car having zinc plated rotors but a nothing vehicle like a trailblazer.... engineers done well to get that past the bean counters !!

Jeez.... some of the comments. As a former garage owner I can't take this anymore.

 

If you asked me I would have said 123 posts on rusty brake discs was not possible. Would the OP please fit carbon ceramic discs and save us all the bother. (Oh Lord what have I started now?)

just came across this clip - it stands to reason as this still frame shows, the brake disks are probably zinc plated, from the factory.......and its a lowly Chevy

Looks like they had to for the view through the trendy wheels..It could be that the OP's discs did not get the final plating..

It's better to burn out then it is to rust, the king is gone but not forgotten.

Read my post again please. Oil on the frying pan.

You use a frying pan as a brake disc, are you joking!

On the subject of paint and fires.

 

Waaay back when dinosaurs roamed I had a 2.3 Litre Vauxhall Viva. It looked like a regular HC Viva but had Firenza running gear including front disks and the 2.3 litre Victor inclined 4 engine with twin-choke Weber.

 

My Rostyle (Boy Racer) wheels allowed viewing of the rotors so they were painted with regular flat-black spray paint, not even high temperature.

 

So, even with my heavy right foot, the paint never even blistered let alone caught fire. The beast was enormous fun to drive.

 

Just saying. I wouldn't actually suggest doing it of course.

Correct, done the same to loads of rides, even the one I have now...Normal use rotors get hot and will burn your fingers, but the hub you can spray paint just gets a bit warm, probably not as warm as a car roof out in the sun....

No, I am using a brake disc to cook my bacon & eggs on.

Why are you talking like an idiot?

[Damrongsak]

Brake rust ... holy Hell.  I once took a crappy company car to the airport and parked it for several days.  It was rainy.  Got back late one night and the car wouldn't back out of the parking space quite right.  Chirp, chirp, squeak.  Turned out, the drum brakes in the back had rusted and frozen. I had to get out there at about 11:00 p.m., jack the car up, loosen the wheel lugs and beat the living <deleted> out of the brake drums with the tire iron until they came free.  The parking lot attendants were curious, but didn't mess with me.  They saw the look on my face.  I was not pleased.

Not sure, how many pages did the classic “ broken Pringles “ thread get [emoji848]

Sorry to say I've known back street repair shops who would give the discs a good wire brushing, charge the guy a silly amount and send him on his way.  They love customers like this. OP is wise to ask advice.
