I need to bleed the brakes on my DS21 1970 manual. In the workshop manual it says to undo the pressure regulator valve 1st and then bleed the brakes as you demonstrate, as when under pressure the bubbles don't form. Is this the correct preceedure?
Apologies for the slow reply - Yes, putting the hydraulic fluid through a tube back into the tank allows the air to be released into the atmosphere and for the fluid to be used again. The system is designed so that many of the "return lines" feed back into the reservoir on one side of a baffle plate, high up while the pump draws the fresh fluid from the other side and low down. The idea is that the bubbles rise and escape and only fluid with no air is drawn back into the system. Ian
Thanks very much for all the super interesting videos....we want moremoremore;-)
More to come!

Hi may i ask why let the lhm goes back in to the tank?
Is it removing the air bubbles without changing the fluid?
