Hi

Thanks guys, good technical answers as usual from this site.

They will base their calculations on the fluid used to fill the movement of the pistons from new pads to worn out pads.

The front pads on my car 18 mm from new and the rears are 15 mm.

I haven't done the calculations yet but they need to see that I have enough fluid to left over in the reservoir after the pads have completely worn out, I guess that they have to make sure the car is idiot proof.

I'm pretty sure that they will need to see 1.5 times the fluid needed after the pads are worn out.

I'm getting a spare Volvo fluid reservoir tomorrow so that I can show it to the engineer and he can use its calculate the capacity.
