dolariCar update.
So the car got repaired, cost $800, but could have been worse as they went ahead and covered the front rotors under warranty. I asked what he thought may have caused the problem, since he seemed pretty adamant it was me.
His explanation - I drive down Novelty Hill Road. Novelty hill road is a 400 foot drop over three quarters of a mile, a 10% grade. And, admittedly, going down that road, I ride the brakes all the way down. And at the end of the road is a light. He says, riding the brakes down causes the brakes and rotor to heat up, and when at the bottom, if you hit the red lights and don't let them up at all, the rotors don't dissipate heat and warp.
I drive down this five days out of the week, for eight months. It kind of makes sense. Dad says this makes sense. But what do you, the grease monkey at home, think?
Bullshit, or no bullshit?

Date: 2016-07-29 11:58 am (UTC)"It is certainly possible to burn up brakes in a hilly place like Seattle, or Pittsburgh (makes SF seem almost flat) and the mechanic is correct that down-shifting (using the engine instead of the brakes to slow the car) will make the brakes last significantly longer.
Warping of the rotors is the result of too much heat (braking for a long period of time, with little chance for things to cool off) and it can happen to brand new rotors in about the same amount of time as when they have 50,000 miles or more on them. This only has to happen one time, on a long downhill, and once they're warped, they're warped. It's all about heat, and the more one uses the engine to slow down, instead of the brakes, the less heat will be generated.
My best guess is she probably did this to herself."
