I was told by someone at the track that my rotors and brakes were glazed (I was having brake problems throughout the day). I have Hawk HP+ pads and stock Type-R rotors. I was told I could take some medium grit sanding pads and simply unglaze the rotors by rubbing them with it.

Will this work? Can anyone tell me exactly what abrasion level I should use and anything else I need to know? (direction to rub in, etc).

 

50 grit sandpaper and use a circular motion on the rotor

what kind of "brake problems" were you having? glazing is generally a problem of improper pad bedding

 

what Morgan said.

50-100 grit sandpaper will work for the rotors.

As for the pads, the easiest way to glaze them is to get them above their operating temp for extended periods of time. HP+ would not be my first choice for a track pad. They could be used at certain tracks by the right driver in a car that has huge brakes. A C5 driving friend used them for ~ year, until he got better and better (read: faster and faster) until they finally weren't enough for him. If you're having problems stopping your car on track with them, it's time to step up to something better.

It's been my experience once pads are glazed, they're a write off. Pedal never really feels the same no matter what you do to the pads.

I am pretty sure I have pushed the pads beyond their ability. I run A032R's now so my speeds in to and out of turns are much faster; I know at one point we mesured rotor temps above 500 (F) degrees, which probably did it.

I will fix the rotors and then go looking for some new pads. My problem is that my car is a daily driver, so I can't use track pads (I would swap them in when I go to the track) that damage my rotors.

Once I graduate next spring I will buy a daily driver, but until then I need a way to make do, i.e. track pads that are rotor friendly.
