Put the clamps back on the flex pipes and see if the brakes stay hard .

If the brakes stay hard then you have still air in the calipers .

Check the calipers and see if the bleed nipple is on the top or on the lower side of the of the caliper .

Should be on the top part of the caliper if its on the bottom part swap over the caliper from the l;eft to right and right to left this will put the bleed nipple on top so you can bleed it better.

T%his happens a lot but not known it to happen on the Cit.

Get back to me .

Hi Alan .

Did not want you to be left hanging in the air so i did a lot of checking around and got in touch with a friend of mine that works on

Pug's and Citroen's he said if the system runs dry or managers to get a bit of air in the system it has to be bleed with the scan tool first the manual way then bleed with the ABS system .

Hope this helps regards Greg
