ap racing calipers

[tuscrv8]

any advice please

had my ap calipers rebuilt by ap and have now fitted them , but i can not get them to seal properly around the bleed nipple as fluid is coming up around the threads after a few hours {seem to seal at first}
they are alli calipers so i dont want to put to much force on them but have put 20lb of torque at ap request but to no avail

they are the rear alli calipers from a tuscan challenge race car

many thanks

Try some new bleed nipples from Jon at Questmead, who will know exactly what spec the callipers are as Questmead were the brake suppliers for the Tuscan Challenge. If they don't work then you may need the bottom of the bleed holes re-seating
