Hi Paul,

Just had a look at my service records.
Front and rear pads replaced at 48k miles by 1st owner.

front pads and rotors only at 75k miles, also by 1st owner

I replaced front and rear pads + rotors at 100k miles.

(Mine's a stick-shift too so I use engine braking a lot. Drive about 75% highway, 25% city)

Hope that helps!
