I was told do not wash your wheels with water after you drive because if the water gets on the rotors when they are hot, you will damage your rotors. This is a tip from my tuner shop...some of you might not think its true or might already know this... im just telling you what I was told.

JUST a TIP

 

thx for the tip i'll keep that in mind....

 

very true....i found out the hard way

 

I suppose this is true. . .warped rotors are frequently caused this way, but what I'm wondering is driving in the RAIN an issue?? Because that's cold water as well, splashing EVERYWHERE. . .

 

i dont think the rain is as cold os the water from the hose...but hey..im not the weather man

 

I thought this was merely common sense.

 

thanks for the tip!!

 

yea i found out the hard way. first time i washed mine i waited a little while to let it cool off. first time i hit the wheels with the hose the breaks let off tons of steam. they dont feel warped, but i wouldnt try that again. now i let it sit for a long time before i wash it

 

Some people lack common sense, but I was thinking that is also common sense

 

oh

 

i don't believe in warped rotors. i don't see any harm in getting water on rotors. you do it in the rain anyways. what happends when you're driving hard and breaking hard and all of the sudden it starts to rain or you run over a puddle? i mean there's a possibility of cracking, just like taking a hot bowl and putting ice water on it, but its very minor. something like this i would hope would have been thought of by engineers, especially engineers that designed an evo a street legal rally counterpart.

ohh here's a link from stoptech site that convinced me about the whole warped rotor thing. respectable company with great product, so i would think they might know a thing or two.

i had "warped" on stoptechs on my car that were brand new. i got ahold of them all they did was sent me abrasive break pads. i put them on did a bit of hard breaking, put old set in and voila no "warped" rotors. did same on my brother's car, a 92 beater civic. had "warped" rotors also. all i did was go out on the high way at 2am and did like 12 60-20 mph break runs, that solved the issue.

 

Not to put a turd on your nachos, but I am fairly certain this is a myth. Yes the water will steam, but that's because the rotors are hot enough to evaporate the water almost instantaneously. The rotors (cast iron typically) are not going to give up much in the way of energy from a little bit of water, and if they do it'll mostly be off the surface of the metal.

The primary cause of rotor warp is overheating, and specifically with our brakes, pad transfer (whereby the pad material fuses to the rotors).

I've had my OE rotors now for 41k miles. I drive this car hard, I brake hard. I go through water, car washes, have packed the wheels with snow, etc. Still no warpage. I attribute most of that to proper initial pad break in and smooth, steady braking as opposed to quick bursts when operating at high speeds/levels of inertia.

Another cause of warpage would be improperly (over) tightened lug nuts. If you've never confirmed that your wheel/tire place is using a proper manual torque wrench, chances are your lugs are torqued to 150lbs+.

 

Let's not forget that cup cars use water to COOL their red-hot rotors. Then again those are usually not cast iron

 

I never knew this actually, thank you for posting (even if it is a myth, I will be cautious).

 

I know it's common sense but won't that be the same issue as to get you car wash at the car wash.
