Front Brake Disc.

[boksaman]

I noticed that my rear disc is more worn out than one on the front tire, the first owner must have used rear brake much more.

 i think that both disc are in spec (gonna confirm that when i get chance), my question woul be: do you guys think is it a good idea to switch them up? - meaning put rear disc at front and front on the back tire, because i'm braking more with rear brake

thanks

in the automotive world when brake rotors are replaced they are paired with new pads. You're asking about swapping your front and rear used brake rotors to help even out wear? Assuming they are the same size, you typically don't' want to use old pads with an old rotor.

Would it work? Probably...but not something i'd consider. If your rotor wars wears out just replace it with a new one.

I would recommend not swapping them, as the brake pads have already worn to the grooves of the disc. There would also be a large gap due to the different diameters between the brake rotors. Both of these would lead to loss of braking performance.

Best to get a new rotor and pads at the same time.

that's reasonable advice . . thanks

I say stock brake disk should last 100,000 miles.  Stock works fine.  Why go thru the trouble?   In over 400,000 miles of Maxi scooter use since 1990----never had to replace front brake disk.....and I am heavy front brake user.

For mentioned reasons, NO,  do not swap rear with front brake discs.
You can't look into those material.
 In my experience front and rear brakes wear out pretty equally, but since in most of the cases its a lot of work (not to say a PITA) to change and maintain a rear brake with all this dismantling of muffler, shocks and most of the time axle- carrier.
So its seems to most of workshops and clients easier and cost effectiv, to change rear brake pads only.
With known result, thinned and grooved disc.
