Lets see, my pads went bad and the brake light and the abs light came on at the same time so i changed them the next day, took it for a ride and no light or anything.... i have 245/40/17's in the front and switched from 275/35/18's to 275/40/18's in the rear and it started popping the same two lights up again, ever since i changed tires. It also seems to brake a little to hard in the rear, you can hear the back brakes groaning. anyone know anything about abs.... gmmg said there are perimiters of how fast your front tires can roll along with your back ones and they said im out of the perimiter with my tire.. but would that make the back brakes grab too much?

 

the brake light and the abs light come on at about 50-55 mph, both of the lights at the same time

 

the difference in tire size is too great from the front to the back. Thats whats causing your ABS problems, and the problem with too much rear brake.

 

hmm.... do you think i could step up 5 in the front and it would be how it was before, or should i go down 5 in the rear like it was before

 

Put on the same size tires all the way around and see what happens.

 

its not that easy....$$$$, i just wanna know how to read the brake codes if the computer even stores them

 

Go back to the tire you had before.
