Please could anyone shed any light why it is so difficult to bleed the front brake system on a CB750 K8 use import
?
I have on Graham and Julies advice brought a S/Steel piston, new master seal kit, new s/steel braided hose which on my model is one piece which is 80cm in length ALL THE SEALS are genuine Honda seals using Dot 4 fluid put in new crush washers at the master cylinder banjo joint
1) I have tried bleeding it by the normal std method of opening and closing the lower bleed nipple
2) Using a syringe I have back bleed it by pushing the build towards the master cylinder
3) Using a syringe I have bled it by sucking the fluid through from the master cylinder
4) Without out the lower bled nipple being open & with constant small movement of the brake lever for 20 minutes.
Comparing the movement of the front brake lever with my CB550K3 My 550 moves back less than half way and then unable to pull it back any further ........ With my 750 I am able to pull back the brake lever back to within 1 finger thickness of the handle bar most times And if i really pull the brake lever hard I can get it back to the handle bar
which i am not happy with ( Not got the confidence in it stopping me )
Any help or guidance why I am having so much trouble with this simple task
