Brakes lock up after changing master cylinder
 

Brakes lock up after changing master cylinder.

2011 Mazda 3 , 4cyl.

Changed master cylinder after soft brakes, pedal would go down to the floor and creep at stoplights. After changing the master cylinder the problem was fixed and we tested around the auto shop and it seemed great. 15 mins later on the way home while on the freeway the front brakes locked up and the traction control came on. We cleared the code and drove more to test the issue. It came back, eventually had to remove the ABS fuse to unlock the front brakes and get it home. We don’t know if it’s the ABS control module or not? Seems unusual this would fail right after changing the master cylinder. Any advice?

Also threw this code C0044:28-2B “Brake Pressure Sensor ‘A’ “

Hello,

I’m trying to find out if anyone has been injured to a faulty brake pedal issue on 2010 Mazda 3? My daughter’s car would not respond to the brake being pressed and resulted in an accident? Any info would be appreciated!

Im having the same issue with my 2013 mazda 3 I was wondering if u ever figured out the problem ive looked up every thread none give me an idea except to replace the abs which dont make sense like u said it shouldn't make it bad by changing the master cylinder any info would be helpful ty
