I've positioned and mounted my hydraulic handbrake in my sierra although the entry pipe for it is normal size I think this is 8 mil although the one behind it is much larger think its 10 mil. How do I pipe this up? I've the front pipe hooked up ok but I've no idea where to start with the rear. I've tried stretching the pipe out with the brake pie kit but it pulls through the fitting.

Any help is much appreciated thanks

 

Ok what I done was I used a larger pipe and when it came to the other end to reduce it I drilled out the fitting. Works fine
