Let me check for more information. What model and year is your vehicle? do you have any other codes besides the P1703 code?
-
i change the master cylinder the two rear calipers right and left i a lot of times every one said it has air in the lines but it shoots the break fuled out about 3 feet from the calaper bleed the breaks and i still have no brake paddle it goes all the way to the floor with no hard paddle easy all the way down to the floor
-
Try bleeding all the calipers following the brake bleeding sequence. Start with the corner farthest from the driver and then proceed in order toward the driver (Right rear, left rear, right front, left front). Based on my experience, if the pedal goes all the way to the floor after replacing the brake master cylinder, the issue could be due to a faulty master cylinder or air still trapped in the system. If the problem persists, you might need to use a vacuum pump to properly bleed the brakes.
