V8 Miata BrakesPower is no good if you can't stop. This is the place for discussion regarding upgrading your stock Miata brakes to handle your new found power.
Does anyone have any experiencing using the Kent Moore ABS tool, which is required to diagnose the ABS systems of the 1994 (and earlier, I believe) cars, since they do not have a TBS wire in the harness?
During my V8 conversion my brake system was open for about two years, and I accidentally tore one of the front sensors when swapping subframes. Since I got it back together, and replaced that sensor, the light is in intermittently, and I would like it fixed!
I purchased the ABS tool 0000-42-0010 on ebay, but was unable to find the harness adapter 49-H066-003, which the Mellens manual says is required. This part has been discontinued by Mazda and I am unable to track one down. From the looks of it, it just provides unswitched power to the ABS pump and module for when the diagnostic tool is hooked up, but I am not sure. Currently the tool will test the sensors (all checked out good) but is throwing a 'check pump relay' or similar. I have checked the relay and it's good, which leads me to believe the issue is actually the pump/module not getting the power it needs.
If anyone has any experience with the tool, knows of a dealership with the tool (or especially the harness), or has any insight on this topic, please post!
