-I had a pin hole in one of the brake lines on a 2011 Arrow X1. The two brake lines were just the nylon tube type. After replacing the brake lines I can't get the brakes to bleed. There are two hoses out of the master cylinder to the caliper, each side has a bleed nipple. I have tried to bleed the brakes with one nipple at a time cracked open and got nothing and also tried with both nipples cracked open and still get nothing. - When I first crack the bleeder open a tiny bit of air comes out but that is all - when I pump the brake pedal it doesn't build up and pressure at all. I have also tries with the cap both on and off the master cylinder - any clues as to what I am doing wrong?
Cheers

I'm not being patronising mate, but are you closing the bleed nipple before you release the pedal again?
If you pump the pedal on and off with the bleeder open, you'll just be moving air back and forth in the system...getting no where.
Can you please outline the exact method you are using.
All good mate, not patronising - I'm a newb and need all the help I can get!! Yeah mate, am closing the nipple off again when I release the pedal. I'm thinking I may need a kit for the piston in the master cylinder, I have taken the brake line off right at the 2 x outlets of the master cylinder, blocked then off with my finger while pumping the brake pedal. When I take my finger off a tiny bit there is no build up of pressure at all - it's like the fluid is bypassing the piston inside the master cylinder and not building up pressure. - I suppose it is possible there may be a slight bit of air in the reservoir itself but think it's unlikely - there is no air bubbles or anything when pumping the brake pedL
Get a sauce bottle with brake fluid in it and a length of fuel line and attach it to the nipple with it cracked open. Give it a squeeze with the MC cap off and you should see air bubbles appear in the chamber. Do it on both sides and obviously close the nipple when each is done.
