When I renewed the rear brake shoes recently, I noted how badly the rear brake cylinders were corroded around the end seals.
I got some replacement parts, 2 litres of brake fluid and then yesterday replaced the rear cylinders.
During bleeding I regularly checked and topped up the brake reservoir and at no point did it run dry, it actually went down slower than expected.
I have bled one side (rear right) and seemed to get a lot more air out than expected. So I did the left rear and after some air was removed it went as expected and the fluid looked fresh and air free for several pumps, I then did the front right (same circuit), no problems.
So I went back to the right rear and despite a lot of time bleeding, more and more air came out. I went to the front left and after an initial small amount of air the same happened there, more air came.
I have given up, as the more I bleed that circuit the more air and less fluid I get and I don't understand why...
I have done this job many times on several cars and not had any issues before.
Have I just introduced a problem or discovered an existing fault?
The car is a 2001 1.9 JTD ELX.
