Hi dear friends… happy Sunday!!!
Im trying to put in functions the brake system … but when try to bleeding the Air… doesn’t work…the fluid not flow through the line…
Help… please…
Maybe I’m doing something wrong …
Thanks …
Fill the remote reservoir, make sure the fluid flows down into the master cylinder. Might take some pressure on the reservoir, then open one bleed screw at a caliper and pump the pedal until fluid expels. Check the WSM for the exact sequence of bleeding at each caliper. I believe it is rear ones first. Using an assistant to open the bleed screw then pump the pedal to the floor and hold down, have assistant close the bleed screw, release the pedal and repeat at each caliper until there are no bubbles in the fluid being expelled.
Was the system completely empty? If so did you bench bleed the master cylinder before fitting up the brake lines? We need to know a bit more information to be honest.
The car had some oil in the reservoir from years ago (15 years or more …) … so I put a little more … … maybe the old oil became glue or something like that … Well, the car has been stopped for many years. should have checked that first … I say … but I opened bleeding screw and nothing comes out…
If the fluid not flow after doing the procedure of pressing the brake pedal and opening bleeding screw for many minutes … what next … ??? Will the lines be blocked … or what else should I check ???
Thanks 
Sounds like you need to have the system overhauled, I would suggest if you are not confident to do this to get a specialist to carry out the work. If the car has stood for that long then all the brake components will need checking.

I second Mr. O Connor’s suggestion.
And I “third” it.
Get a professional to help you.
If the car has not run for 15 years or more you will need to do more than just change the fluid, which ALL has to be changed.
If you’re not familiar with braking systems I also suggest you get someone to do it for you - brakes are not a luxury !! 
And don’t overlook the hydraulic clutch system which could have similar issues.
I am thinking of rebuild the caliper or buy new ones … with the old ones I don’t know if they fit well or there will be some problem of leaks … with the new ones it is == the money😄 they are expensive … $ 130 each … I need 4 front ones … it is a lot $$$$
what do you think …
Those cylinders appear to be beyond redemption for the amateur DIY. Have you considered sending them out to a professional repair shop?
I did not know that I could send them … you have any website …
Thanks…
I think they are called White Post, it’s in your country so you should be able to google them easily.

depends on whether the seal is on the caliper body or piston, both can be re-sleeved in stainless steel, and it is less expensive than “new” ones
the machinery to do it was invented in Australia, and exported worldwide, almost all Oz brake places send theirs to them to do it (I have had calipers, pistons and masters sleeved)

Thanks …thanks to you … for your time and answer … I’m going to call those guys…
I owe you a lot😊
Can you give me your point of view … what would be the advantage of sending the calipers and pistons to be repaired … each one $ 85 more or less … and the other one to buy new ones at $ 126.00 each … those that it brings my jaguar are Dunlops (maybe they will be the originals … I don’t know) … I just want to see what is convenient …
Looking at the state of those I would spend the extra and go new.
is it possible to put on the rear brakes caliper 2 1/8 (front) instead of 1.5 … ?? is there any why ?? the rear brakes bring caliper 1.5 ?? if it is for reasons of specifications and techniques … better leave them as they are … so as not to get into so many problems …
Thanks
