Megane II 1.5 Dci ABS location

[Logic28]

After having checked the LHS rear calliper because of a weak hand brake, I proceeded to bleed the line.
Since then, I have a slow-sinking pedal under high foot pressure, which feels like a leak, so before I check the master, I wanted to inspect all the lines and the ABS unit to see if there is a leak anywhere.
I cannot find a reference to the location of the ABS on the 2007 Privilege model. Is it located at the front or rear of the vehicle, please?
Many thanks
