Pierced Bronson posted:Confirmed. On my bud's old 240SX we installed stock 300zx 4-pot brakes up front without changing out the master cylinder and the pedal feel was touchy. It worked but was hard to modulate, and also the proportioning bias became incorrect. The coating is zinc plating probably with hex yellow chromate and it's so the rotors don't rust to the car or wheel after installation with a bonus of looking nice on the shelf. It's a big deal with most OEs now and there's a lot of work on spray/dip coatings and nitro-carburizing to replace the plating but it's hard to make cost-effective since plating is so cheap and heat tolerant . Brake component corrosion in general is getting a lot of attention because of how open wheel designs are on modern cars.

Bape Culture posted:Neat cheers for the info! Does that mean they'll stay looking like that then or is it just on the surface? I assumed it would burn off! Covered areas will stay somewhere between that and powdery white, uncovered will likely go white or rust, and where the pad goes will scrape clean really quickly. It's like 10 microns of soft plating, max.

Bape Culture posted:Hahaha. I'm glad I brought in my CAE setup last week! It'd be cheaper to have someone make a new knob out of solid copper. Hydrodipping is a decent option if you don't want a metallic though.
