Is there anything majic about ATV brake hose? I am in the process of rebuilding the brakes on my 2000 Xpedition 425. I was having problems bleeding the brakes and found both the front brake lines will not pass air. Tried pressuring up from both ends. Is there an orifice in the brake lines for some reason that might be clogged?

I will add it is a good idea to replace your brake fluid periodically. I didn't consider this and am looking at some expensive repairs. Most brake fluids attract and absorb water over time. Water leads to rust and contaminated fluid. One of the ports in the master cylinder is really small and will plug at the slightest invitation if your fluid is the slightest bit dirty.

try taking the lines off and flushing with brake cleaner. A mighty vac will also help pull the fluid through once reassembled and sometimes the vacuum from it will dislodge a clog in the system. Anything over 4-5 years old should have the fluid changed in it, even with the newest dot5 fluid.
