    99 V8 ABS problem solved !!!!!

    I am very pleased with myself . My younger brother's car has had 3 amigos and brake problems since he got it 5 years ago. A few experts have had a shot at fixing it, but didn't succeed. SO.....

    Falconworks (US supplier) supplied shuttle valve and switch repair kit (Wabco bit) landed for A$171. 3L Dot 4 brake fluid.

    Removed modulator, replaced shuttle valve seals and switch set, replaced modulator, power bled modulator circuits a la "The Good Oil" (thanks Graeme), bled the brake circuits as normal, and

    D DAH.

    A beautiful thing. Out with Nanocom, select Disco 2 SLABS, read faults (find that faults registers are jam packed), erase faults and NO AMIGOS.

    The best bit - the brakes are sensational.

    It took 4 hours go to whoa. Chuffed.

    Cheers

    Why did you go the full monty on the ABS, why not go option B?

    I think you'll find in about 80 - 120k more you'll get the bro's back. Maybe not. (Pretty sure the ABS is just bad design and not sure this has been addressed).

    Sounds like a bargin price though considering what a 'professional' would charge.

    Regards

    Andrew, I'm just a bit bleary about Hummer fixes. Perhaps it will be back as a result of compromised design, but who knows?

    Thanks for the input.

    No worries. I have done the operation but not entirely sure it's perfect either.

    Everything works as per normal but on the odd occassion I hear the three chimes which would go off when the 3 amigos came on.

    Both the fully monty as you have done and Option B are relatively easy.

    Regards
    Andrew
