What brake material is better and wont rust or corrode? Gold cadmium plated, Gold zinc plated, or Zinc-dichromate plated? and what size diameter rotor and thickness for a 91 crx si ?



Gold cadmium plated

Gold zinc plated

Zinc-dichromate plated

 

How will brakes rust if they are in use ?

 

on the edges

 

i like the blueberry bakes.

Yeah, I'll give you that but have you ever had an issue with them rusting that bad that its a problem ?

 

They will all rust. Not only that, x-drilled will start to crack.

 

^^ true!!!

Use Axis bads they work good, or some AEM pads also. I have these on mine.

key word plated there just painted rotors when u stop it will take of all the coloring the rotor.

 

How thick do you think the plating is? A mircon or so?
How fast do you think that'll wear off?

You're asking the wrong question.

 

i recommend these

Rusty brakes will look crappy, but will always remain functional from a safety standpoint. Crossdrilled brakes that develope cracks in them are never safe. Given the temps and harsh environment they'll see, I doubt the coating will do much more than give a few months of protection. The only rust-free brakes that would even be an option for the street would be tiny carbon-fiber or ceramic brakes with aluminum, magnesium, or titianium calipers. But when you have a single brake disc thats worth more than your car...you know you've gone overboard.

 

I use to have some slotted rotors, powerstop or powerslot or some crap, well anyways they were silver aluminium like color, and the whole time i had them they NEVER rust on the edge's. I think you can order a pair at pepboys even, for like only 60-70$ i believe, Im gonna get another set when i get the money for the hatch i got right now, because guess what, those bitches are FRIED, lol...you should see how bad my steering wheel shakes.

 

Suprisingly ive had some nickel cadnium plated rotors on my PGT for about 4 years now and they still look like brand new except where the pads wore it off (but that part stays clean as long as you drive lol)
If i were to do it all over again i'd get black ones so they end up all black except for the worn part since i have 2-piece rotors up front with black hats so they'd match.

 

I'm not going to argue the quality of any of those rotors vs. the others, but if they do have a corrosion resistant coating, then this coating should stay intact in the parts of the rotor that don't touch the pad (ie. the edge of the rotor). The heat could also damage the coating, but that is a separate issue.

Relating to the original question, I don't see how any difference in the coating material will have any impact on the performance of the braking. There are many other factors such as disc diameter, material, and build quality that will affect the performance. Probably best off to stick with a rotor that is known to be a quality product.

 

so cross drilled rotors crack, but slotted rotors wont?

to the op, I guess having them plated will help at the edges.

 

To be honest imo, i would just get oem blanks, wagner blanks, brembo if you a rich guy that likes honda's, or the powerslot i was talkin bout which i like. All those i said are the only ones i would really suggest and like myself, but when it comes down to it all they are all fine rotors, so are most pads, but what really counts is havin good tires really.

I couldent agree with you more

ive decided to go with the Gold cadmium plated ones because they are the most expensive between the 3, $149 a pair and should be the best ones

thanks for everyones help
