Please help on my oem brakes

That causes the rotors to wear a little faster then if you drive regularly. Rust can also make noise but only for the first brake application or two after the car has sat for a few days. Not likely your front brakes are worn out just yet even if you drive like a maniac, these are light cars with big front brakes for their size.

Rotors are designed to last only for about one set of pads with a bit of extra thickness to allow for variation in braking habits.

Seizing calipers make a knocking sound and you can feel the rotor runout through the brake pedal as well. It is unlikely your calipers are seizing at this young age.

I recommend you brake harder than you are accustomed to, at least a few times a month. This will help reduce brake noises

Very interesting, thanks so much!

Generally speaking many get through five sets of pads per disk. So worth to be more careful with stating such "truths".

Unless you plan on putting another 30k miles on this year or starting to track/autox I doubt you'll need brakes next spring.

Brake fluid would probably be a good idea though.

did the brake fluid already at 29k. We'll see hows the budget for next spring, i might want to upgrade brakes and pads.

The surface on cast rotors shows surface rust very quickly. That rust has zero effect on the wear or life of a rotor. None. Zip.
Rotors for some cars are indeed small and light enough they should be replace with each set of pads. Ours are not those. You should easily get 3 sets of pads or more out of a set during normal driving.

Anyway, i do think the sound is not as bad as before (although i still need to drive the car a bit more), however AZP did also mentioned that my tires are starting to get 'road dry' meaning that i should start thinking on replacing my tires at some point. But no budget for tires right now so thats gonna have to wait until next spring so i can do the wheels/tires and possibly brakes.

Thanks for the update. So the original tech was full of shit.

Yeah, well, stock suspension and alignment is best.

Just add MCA kit in, and it's like F1 formulas.

When a shop tells you to get tires, you should probably get them. AZP would not lead you in the wrong direction. Tires are all you got when it comes to grip. Old tire = unsafe.

Not zero, obviously. If you're getting three sets of pads on one set of rotors you should trade your BRZ for a Prius.

"For normal usage conditions, the design*life of the front wheel brake discs should be equivalent to the useful life of two sets of*corresponding brake pads. Some discs may have a shorter useful life, because they*have been designed to achieve specific targets."

NORMAL driving. That does not mean driving it as a Prius it means driving it as it should be on the public streets.

You said one I said 3 your own link puts it in the middle.
