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... Link to comment Share on other sites More sharing options...

They are the original disks, I never touched them. Zinc plating is (was?) very common. My 2018 Benz has zinc plated disks, too. Link to comment Share on other sites More sharing options...

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 !!

DaRoadrunner Posted September 13, 2019 Share Posted September 13, 2019 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?)

Crossy Posted September 17, 2019 Share Posted September 17, 2019 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....

Damrongsak Posted September 18, 2019 Share Posted September 18, 2019 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. Link to comment Share on other sites More sharing options...

nanglong218 Posted September 18, 2019 Share Posted September 18, 2019 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. Link to comment Share on other sites More sharing options...
