It's complicated to do this
Your reply on the first post said fluid ok and no leaks , so WHY do you want to replace them?
i found that the break fluid is empty !
SO did you find the source of the LEAK , is what I'm asking?
no i did not how i was thinkin if i kept it running empty it'd prolly make it worse how to trouble shoot break leak?
put fluid in and have someone observe while pumping clutch pedal by hand.
