"ker ko na sprednjih kolesih zavira regeneracija, morajo to nalogo na zadnjih kolesih opravljati bremze. "
zanimivo, tega pa nisem vedel, ampak verjetno spet v določenih pogojih?

OK - a little review on how Volt's braking works. i harken back to an interview with Andrew Farah, where he explained how the Volt used 100% regen braking (which is all front braking) through about 0.2 g's, then started "blending" and tapering in the hydraulic braking up to about 0.5 g's, then it was 100% hydraulic from 0.5 g's on, because then the ABS, etc. has to be ready to kick in. He suggested that the conventional braking was starting to kick in when the green ball started to turn yellow. That does happen a lot for me, and I'm not an aggressive driver.
If one were blending regen and conventional between 0.2 and 0.5 g's, then that probably means engaging the rear brakes more than the fronts, as the regen is already handling the front until the g's get closer to 0.5 g's. Therefore, it would be only logical that the rears would wear more than the fronts.
I'm curious now about what the actual average brake wear rates are on Volts, and how it compares front to back. Anyone actually mike their rotors or measure their pads when they do tire rotations or changes? I've always boasted that with all the regen, my Volt may never need a brake job, but now I'm second-guessing that claim.

Ferritic Nitro-Carburizing
A General Motors’ team of global brake experts is helping to make rusty brake rotors history by changing the chemical makeup of the components using a process that could double the life of rotors and save consumers hundreds of dollars.
The engineers developed an exclusive corrosion protection process that super heats the rotors at 560 degrees Celsius for a day in an oven the size of a tour bus. Inside the nitrogen-rich atmosphere, nitrogen atoms bond to the surface of the steel rotor, hardening and strengthening the rotor.
The name for the technology is Ferritic Nitro-Carburizing, or FNC, and it has most often been used to treat powertrain parts.

Navadn avto je in pri vseh avtih se za zaviranje uporabljajo zadnje zavore v kombinaciji s sprednjimi.
Imajo kaj korodirane povrsine? Moja zadnja leva ima cca pol centimetra pri centru diska in cca pol centimetra korodirane povrsine na zunanjem robu diska.
Celi kraterji so gor, mehanik pravi da se da vseeno še enkrat postruzit, samo nisem prepričan, odvisno od cene novih...Vsak disk je rjav tam ko ne drsi ploščica....
Pri tistih ki bremzo božajo pa še tam kjer ploščica drsi. To je pa itak samo še za staro železo.
