Marks on Rotors
 
Yesterday I just gave my car a rinse to get rid of the pollen on it, parked the car and didn't drive it for the rest of the day. When I went to work this morning, when I first started backing out of my garage I heard/felt a clunk from mostly the rear. My brakes were also making rubbing/grinding noises when the pedal was pressed on the way to work.

Now I know when rotors get wet they develop surface rust, but I've never experienced it like that before. It rained today while at work, and they made the same noise on the way back. Anyways, once I got home from work I took a look at my rotors and found this:

Each rotor has a spot like this on them where you can see a mark left by the pads. Anyone know if this will wear off or are my rotors fubared? I'm not terribly familiar with brakes

After a few stops they will be gone. In general, you don't want to apply your emergency brake when parking overnight if the rotors are wet, you will get that same kind of thing only much worse. You also shouldn't apply it if the rotors are still very hot from aggressive driving.

Good to know. I knew about avoiding it on hot rotors, didn't know to try to avoid it if the car is gonna sit overnight with wet rotors.

Just get in habit leaving it in gear (if MT) instead of using parking brake. And after track session do a cooling lap.

The parking brake is a drum type system, doesn't use the rear caliper..

Imagine what the drum surface looks like. Car will definitely be look FUBARed if you got a visual. lmao

Will still scorch your brake shoes if you engage the parking brake while they're hot. So you'd still want to take the same precautions.

I know that. But it being drum type doesn't mean it cannot sieze, or freeze in winter. I've been tought to leave car stationary in gear, unless on steep incline or if diesel, that can self-prime w/o ignition, using parking brake usually for short periods of time or eg. by starting going up steep hill. By all those years driven using gearbox when parking has become natural habit since long ago.
LOL, i've also been told if i'll ever go to France, to never leave car with parking brake OR in gear, only in neutral to enable rolling, due their "parking methods" of multiple bumper contacts to squeeze between other cars
