    Check your brake and fuel lines!

    Just an FYI for all isuzu 110 owners.

    I didn't notice before, but my OEM plastic fuel lines were rubbing against the OEM hard brake line just after it comes out of the slide valve, at the base of the footwell.

    The fuel lines appear fine, but they have rubbed a pinhole in the brake line!!!

    As a result I just had to drive ~3500 km with only the front brakes...

    I think I made a post on this about eight years ago!

    This is a prime example of the fact that if a hard and soft material rub together in a dirty environment, it is the hard material that is worn (grit embeds in the soft material and it acts like a file).

    In my case a local brake specialist cut the line, flared the ends and put a joiner in.

    I suspect the problem starts when you replace the rubber section that joins the nylon line to the metal stub at the injection pump, and don't get the length exactly right.

    Holy Mackeral!

    I bet if you watched the re runs of MACGYVER good old Angus would have found something like a bar of soap some quick setting concrete and some chewing gum and would have fixed it for you.

    I was impressed that I managed to use a muesli bar wrapper to stop the leak (but I disconnected the rear circuit to do so).

    You would be surprised how little the rear brakes do. I still had all 8 pots in the front (not like a rangie's setup where if you lose rear brakes you lose 1/2 the front as well).

    The only time I noticed was when I was pulling onto the shoulder and still braking a bit heavily when one wheel hit the gravel.

    I did make sure I used the gearing rather than the brakes to go down cunningham's gap though!

    I dropped the old lines at a brake place today (the two lines for the rear brakes as I cut and sealed the short line from the MC to stem the leak).

    I was amazed at how worn the brake line was. There is also a worn section about 3" long behind the pinholed section, where the fuel and brake lines run side by side on top of the chassis. I will take some pics if I can get the old line back.

    I was quoted ~$40 for the two new lines, including new fittings.
