Putting car in neutral with ebrake on before washing it warps rear brakes?
So says this thread (I think):
https://www.rx8club.com/rx-8-discussion-3/another-tip-new-rx-8-owner-75147/
That's the first time I've heard a claim that one should put car in gear, rather than in neutral with ebrake on, in order to avoid warping rear brakes.

So, this is relatively true (if they are hot)?
Wow. This is complete news to me.
I'm glad I asked, though.
I rarely put my car into gear when parking it, unless I'm on anything other than a totally flat surface.

yeah what expo 1 said :
If you are using heavy braking, and the rotors/pads get hot, when you stop, leaving the hot pads tight against the rotors (parking break engaged) can cause a temp difference as the area the pad is contacting will stay hotter than the rest of the rotor, this can cause the rotors to warp or cause stress cracks.....really a non-issue unless you REALLY push the car. Normal braking or even 1 or 2 hard brakes wont really cause a problem.
One way to avoid it is to drive around for a few minutes with out using much braking. I always have a slow drive thru my sub-division before I park the car.

By the same logic, after a spirited drive, you come to a long red light. You have to sit there with the brakes applied. Now you have all 4 pads in lengthy contact with one spot on the rotors. It's actually going to be way worse for the fronts.
There's another thread dedicated to the subject of rotor warping. It all comes down to the design and the quality of construction of the rotors. One would hope that as a high performance vehicle, the 8's rotors are designed and built to withstand all of these normal usage modes.

Thoughts of warping rotors remind me of one of my other vehicles -
I had a terrible time with front brakes on my wife's `98 Grand Voyager after we moved to NY. It seemed like the semi-metallic pads only lasted 10,000 miles and they were noisy and ineffective the whole time. I think the rotors were replaced about every 20,000 miles. I had four different service shops do brake jobs with little difference (at least two of the shops did turn out to be semi-crooked and reputed to do shoddy work).
Then, the local tire and service shop where I have since serviced all of my pre-RX-8 cars (Toyota truck, Subaru, and an F150 in addition to the wife's mini-van) made me a great deal on ceramic pads and a lifetime warrenty on rotors. They've charged out replacement rotors and labor to the part vendor once in the past 60,000 miles, but it didn't cost me a thing.
I see a lot of specialty rotors for the RX-8 online, particularly for racing. Has anyone found life-time rotors for their street-bound RX-8? I only have 1700 miles on my `8 so it's not a concern right now, but why not get lifetime rotors with that first brake job?

So, let me be perfectly clear here:
Is everyone saying not to use the ebrake on a regular basis when parking, especially after a spirited drive?
My usual protocol is to park, put the transmission into neutral, and engage the ebrake.
I've done this with other MT cars, with no rotor warping.
I've heard too many stories of MT vehicles popping out of gear, without the ebrake engaged, and rolling into God knows what, when parked.

I thought the replies were clear; it’s heavy repeated braking like you would do on a track or road like the dragon or the hills in San Francisco that heats them up to the point of possible brake warping. Hot enough so that you can smell them. Hot enough that you would burn your fingers if you touched them. What kind of street driving are you doing to get brakes this hot?

But some of the responses at least insinuated that hard breaking cycles of just several times may heat the brake pads and/or rotors to a point where using the emergency brake may not be prudent.
And I like to be prudent.
I don't drive my car hard, so if the clear answer is to use the emergency brake without worry when parking, under those circumstances, I can live with that.

RotoRocket, there are a lot of people here who seem to think their cars are made out of crystal. I shall continue to use the parking brake as I always have, with ne'er a problem. Nice job by expo1 and KYLiquid of explaining the issue.

You should always put the car in gear when parking. The parking brake will not always hold the car on an incline. There have been many stories of people returning to their cars, and finding that they rolled into another car, or something else. On an incline, you should set the parking brake to take pressure off the transmission.

someone correct me if I'm wrong but isnt the parking brake pads seperate from the regular rear calipers. I though it was two smaller pads inside the rotors with a mechanical linkage..
on another note the only problem I have had is that sometimes after a hard drive and parking on a incline I've had my car roll.... after setting the parking brake very well. consequently i always leave it in gear now too.

I am confused here. Does spirited driving have anything to do about driving on Halloween, or is this an open container issue (say, like, driving with jim beam).
Thanks for the US129 map Expo.

Basically drive the **** out of your car

i wouldn't say spirited is that far.... its a level below drive it like you stole it...
and about ebrakes... they freaking suck... honestly.. i found my car rolled out just barely into the street with the ebrake on... but i musta forgot to put it in gear.. or it popped out... eitherway.. it was quite scary to see it like that...
so no more trusting ebrake for long periods of time

Let me clear up some confusion here, obviously spirited driving means different thing to different people. What I did was repeated heavy braking (trying to figure the threshold of it) in a closed abandoned road (lots of twists). I fried the brakes in my other car before (the brakes were smoking) although its not a performance car so it was just a "better safe than sorry thing".
