I just change my brakes at the dealer anb its making plenty brake dust than my previous brakes anyone have the same problem

 

I try not to write in confusing one sentence posts that lack any punctuation and make no sense because it just confuses people for no reason

 

If you had it done at the dealer, I assume they used OEM Lexus/Toyota pads. Not sure why you'd have a dust problem...

 

It appears that the pads the dealer used are not the same as the originals - I would ask for an explanation from the dealership.

By the way, how much did the dealership charge you for the brake job and exactly what did you have done?

 

Perhaps the dust covers/dust shields were not put back on?

 

Or this?

TSIB L-BR002-06 (’06 –’07 GS430 & IS250/350 & ’07 GS350/450h): Excess Brake Dust Issue
Some Lexus vehicles are equipped with high-friction front brake pads, specifically designed for superior braking performance and response. As a result, under certain conditions, it is possible for the customer to experience a larger volume of brake dust on the wheels. For customers who find these characteristics objectionable, an alternative brake pad material has been developed. As with any change made to brake pad material, braking performance and feeling may be altered and could possibly be reduced under certain driving conditions as a result of their usage. These alternative front brake pads have now been made available as service parts.
