Brake pads when to replace

[slattery]

Just had our 2010 is250 serviced including replace front rear pads and machine 4xdisc. When I checked the previous services, I noticed the car has done 23000klms since rear pads and discs were last replaced. Is this normal wear for rear pads? Should I be concerned?

I didn't have to change my rear pads until after 100,000km. Fronts were around 60,000km from memory.

Surprised you machined the front discs. There is only 2mm of wear available on those before they need replacing (28mm new, 26mm due for replacement). Those only last me around 20,000km.

Thanks  Atlanatis,  I'm not sure if pads needed replacing. The mechanic phoned me and asked if OK to replace pads and machine discs. Only after I picked up the car did I check when pads were previously replaced.
