pressure relief on system

[Mark_Lancaster2026]

Hi
I am sorry if this has been previously covered but I am thinking about servicing the hydraulic system my self and was looking for some advice.
I want the replace the hydraulic pump and my Xantia and the front accumulator. I know that I have to lower the car to remove pressure from the system and then release the pressure plug to release all the pressure.
But I am uncertain where it is , on the pump its self or on the accumulator ?
are there any other pitfalls I should be aware of

thanks in advance

I think you will be able to find the Repair Procedure for that starting at: https://szervizdoksi.hu/citroen/sb.html#/v?ldp=1C2X

I got to this page as an example but not using your car's details : https://szervizdoksi.hu/citroen/sb.html ... CT0337&t=2

The pressure release screw is on the regulator (that the accumulator is attached to). Only needs to be undone a couple of turns.

on the pressure accumulator....No need for more than a single turn ( DO NOT REMOVE the Bolt!as there is a spring and ball bearing in there) , low on the front of the engine (13mm ?)
