I’m have difficulty bleeding the brakes on my Clio valver. Removed the rear callipers first, cleaned and greased them and then when trying to bleed them with a pressure bleeder at 15 psi and pumping the brake pedal up and down steadily with the ignition on and off, no brake fluid is coming out. I have been told my brake compensator is seized. Does this sound right and where can I get one from?
