Question about brake discs
Question about brake discs
As some people already know I've done the G60 brake conversion. I think I've done about 20k with them now. The other day when it was raining I drove the car about 5 miles and just decided to look at my discs, (don't ask me why because I don't know myself, lol) and I noticed the outer and inner edge were still all orange with rust (about 7mm outer and inner) but the rest of the disc was nice and shiny as brake discs usually are when used. Is there a reason for this? My pads are due to be changed but surely this wouldn't happen? Any help or advice would be appreciated. Thanks
Im no expert on brakes having never performed any kind of conversion, but isnt the point of upgrading to a g60 brake set up that the discs are bigger therefore giving you a greater surface area of friction under breaking which makes you stop quicker?
so if you are still using the gti spec pads with the larger g60 discs you are not getting any benefit over the standard gti set up are you?
So yes, it seems that the rusty bits are where there is no contact being made, so the extra part of the disc that you gained when doing the conversion (the bit that is going to give you any benefit over standard) is actually redundant.
I would assume therefore that the g60 pads must be larger? (although i have heard that the g60 and gti callipers are the same apart from the connection for the brake hoses?)
if this is the case then you would need g60 pads with your g60 discs to make use of the whole stopping serface. but as mentioned above it could be a bit dodgy changing them after 20k of braking, as your disc may have the efffect of a step where the surface has not been worn by the pad, so you may get dangerously dodgy braking for a while until the new pads 'bed in' to the uneven surface of your discs.
feel free to correct me if i am wrong on any of this
