thanks for your reply bro.

for me its ok to re-do the surface if my car runs 50k or more with a driver that is heavy foot on the brakes.

yes i will ask them to make sure that the caliper pin is put back well. do i need to replace the caliper pin to be sure?

it happened like 3 years ago, we didn't know that practice previously sa casa's, plus my wife has a 200% confidence sa casa eventhough they charge ridiculously. what's worst is the shocks they replace is made in china pero with toyota badge daw, a kyb shock is way better. never again.....
