Does anyone know how to bleed a power hydraulic system. changed a low pressure switch and lost all the mineral oil out of the system, refilled the reservoir with oil, started car and the pump and the valve block are banging and are not pumping oil, must have a air pocket somewhere, I was told that the system and the regular brakes work together and if I just bleed the brakes it would be fine, doesn't seem right with me, there is no oil going through the pump, valve block and to the charge and low pressure switch's there must be a way to bleed this system. Thanks Mike

 

Since no one else has stepped up I will give you my 2 cents worth.


I don't believe there is any difference in procedures. I did a brake fluid flush on my 05 XKR using the traditional method and all went well. Without going into the design of the system it's my understanding that your current advice is correct.


Perhaps this post will draw some additional informed comment.
