how do you prevent rotors from warping

Don't keep the brakes applied after a hard stop, let the car roll slightly. This causes uneven cooling and warps the rotors.

stop stomping on your brakes you caveman

avoid water after braking for long period of time or hard braking.

>>16817611
Use the handbrake to stop instead

Don't use your brakes. Coast until you slow down.

you cant

>>16817611
spread a little 10w 30 on your rotors, it'll help keep them maintained

Take the rotors off, put them back on when parked.

>>16817611
Disconnect or disable the warp core

I don't know why they even put those on cars.

semi-related question: rolling down a hill, better to lay on the brake or pump?

C) Downshift

D) Accelerate

heel and toe faggot

I drive an automatic :^)

Generates the same amount of heat afaik
I'd say slower braking is slightly better because it offloads more of the braking to the rear

pump the brakes and slow the fuck down. Accelerate slower if at all possible. Brakes work via friction, anything that gets rid of said friction is bad. Lubrication, water, ice, etc.

Most if not all brakes cool off via air convection. If you are heating up your brakes THAT BADLY. Install some fans that turn on and off a couple minutes/seconds after applying your brakes. Pump said brakes because hot brakes are not as efficient as cooler brakes. Think about the propane torch to stuck nuts/friction fixes commonly used.

Pull it back into 3 or maybe 2. Still works in an automatic

Unless you're getting your rotors glowing cherry red hot it's physically impossible for them to warp due to heat.

Clean the rust off your hubs, use a dial indicator to check your rotor for runout after you've installed it and I guarantee you'll never have a "warped" rotor again.

>>16817611
put it in reverse to slow down, instead of using the brakes you plebian

>>16820991
Really? I'm going to do that in the morning

"Warped rotors" usually refers to uneven transfer layers due to improper break in or to lateral runout due to a contaminated rotor mounting surface. While rotors do warp and anyone that tells you they don't is retarded, rotor warpage is almost exclusively in the form of cupping, which results in a weak or spongy but typically not uneven brake feel.

See the dark band on the rotor? That's caused by cupping. It's impossible to resolve entirely without rotors floating on buttons like a motorcycle, but it's exacerbated by heavy loading and rapid cooling.
