I did a front brakes serivce, changed pads, and rotors, also rubber lines because they were old.

when I bled the the front brakes, everythign was fine, but the rear are not even getting pressure, do not work, I bled the master cylinder where there are two bleders and in works fine, I never got this kind or problem before and I want to know why the rear brakes do not get pressure and do not stop the wheels.

I know theres is an ABS light, the book says to star t the car and not to press the brake pedal if the light does not go away agfter 3 second and stays more than 8, I need to know what I have to do next, I know I still have to check the rear brakes shoes, but I know there is a good pedal, it is not spongy and it does stop the front wheels, please write me back, also it has a good brake pedal.

Thanks.

Your car has a diagonal braking system, this means your LF and RR are paired off one port of the master and RF LR are on the other, try adjusting the rear brakes! The pressure split is about 85% to 15% front to back, so the pressure required to stop the front tires from spinning is much less than the effort at the pedal needed to stop the rears from spinning!
