Bought from Toyota dealer genuine brake pads (front part 04465-48150) and (rear 04466-78020).
Front pads are Advics, which is no surprise as I know Toyota/Lexus uses Advics pads. Somewhat surprised to see the rear pads are Akebono.

Still not too perplexed until I found white paint on 2 of the rear pads and purple paint on the other 2. The 4 pads look identical and markings are the same, except
White marked pads have marking 910J3. N24
Purple marked pads have marking 911GO N24
Internet search has not helped.
Anyone know which pads go where? White pads on same wheel? Whites onboard? Purples inboard?.

Live in Australia. Car isNXx200t F Sport 2015. Note NX cars use same pads as Toyota RAV4.

Also the 4 front pads look identical and markings are the same, except 2 are marked 4613 A24
The other two are marked 4614 A24

Any help much appreciated. I decided to go OEM to keep things simple. Now regret this. If I had bought Bendix, know from past experience no such confusing markings.

 

Here is what Lexus has to say regarding the colored marks on the pads:

 

thank you.
