so i was on my way home from school. and then there was this civic si..... (what happened is censored in fear of getting banned)....


but here's the problem: as i was braking (hard) after the *cough* incident, my steering wheel started shaking like a mo-fo and my brakes felt like they were fading fast, accompanied by an annoying whistle-screeching sound.

so what happened? and how can i fix it?

brakes are stock.

how old are the brakes? sounds like thickness variation in the rotors and heat fade due to thin rotors. the friction coefficient decreases a lot when your rotors overheat. sounds like a simple brake job would be cure what ails you.

then, stop street racing and you won't come across this problem more than you have to.

New rotors and new pads. Yours are warped... you could try new pads but I'd say screw that. Just get some new rotors and pads on there, you can do it yourself... only takes a couple hours at most.

Oh and chances are you boiled your brake fluid, get it flushed and some fresh fluid in there.

If you get Cryo treated Rotors, you'll never have to worry about warpage again, and they will last 3 to 4 times as long!

technically, the rotors don't warp. they get glazed or begin to have thickness variation.

They can develop thickness variation because they're warped (lateral runout). This wiki page describes various causes quite well.


20 years ago, we used to cut "warped" rotors routinely to true them, now they're so cheap, there's really no point.
