My ABS light has been on for years. When I went to the Ford stealer/dealer, they said it was the ABS module & the price to fix it was like $800 so I said f**k it I'll live without abs & traction control since the abs problem also affects the traction control. Years ago I upgraded my brakes from the GT brakes to the Bullitt ones which are basically the Cobra ones with nicer calipers. Dont remember if the light came on when I did the upgrade since it was so long ago. Finally this January, I decided to get this fixed. I bought a used abs module & the mechanic said one of the lines was cut too close so I had to get another one. Got the newer one installed & the light came back on & the mechanic then tells me that because I'm running staggered size tires that will cause the light to stay on. I'm running 295/35ZR18s in rear & 245/40ZR18s up front. The difference is I think miniscule like .4. I disagree with that. He also told me the right front sensor was bad so I bought a new one & changed it but the f**king light is still on. Do I have to change the other 3 sensors & pray to Pope Francis that it'll fix the ABS & Traction Control issues. WtF.
