K1200 LT Integral brake system

<< < (2/2)

Airportech:
Thanks for your reply the brakes got more and more unreliable, I bought a secondhand iabs unit which was worse than the one I've taken off so I've done away with the system altogether. I've repiped the brakes and they work ok removed the ABS warning light relay and the other warning light circuit I just need to work out why the brake lights are on all the time, but I'm getting there.

Cheers Bren

andres14725:
The brake light on the LT is controlled by the ABS Modulator. If the light stays on you could have a sticking brake switch, a faulty brake relay or a problem within the ABS Modulator. If you removed the ABS Modulator you'll need to adapt the wiring from the switches at the brake levers to the brake light relay in order to bypass the ABS Modulator. The feed to the relay is not switched and a faulty relay could therefore keep the brake light on. And finally, I seem to recall that the brake switches are of the normally closed type to work with the ABS logic, so if you are removing the ABS you may need to replace the brake switches.

Airportech:
Your right the brakes have a normally closed type switch I have had the fuel tank off to remove the ABS relay so I may have to remove the tank again to remove the brake light relay, because the relay is permanently live it might overheat and the fuel tank is above it (fire risk) so if I remove that I will have to wire up the brakes differently, I will be glad when it's back on the road, thanks for your interest and input.
