2012, 5.0 2 wheel drive. the wheel pulls to the right when braking under stop and go traffic. it seems to even out after the initial application of braking. if i'm coasting about 25 or so and stab the pedal it pulls severely to the right. under hard braking it's ok. i've replaced both front calipers and now i bleed the left caliper every couple days. i always get a bubble then it brakes a little better for a day. it's been doing this for a couple months, i don't know if it's getting worse or not but it's bugging me. a couple weeks ago i got a code and i used my blue driver which pointed to the left front abs sensor. last year i got a code and found the connector rusted out. i cut the connector off and soldered the wires. the connection still looks good and i pulled and cleaned the sensor. there pretty expensive so i need advice before throwing more money at it.

 

two months ago i dropped the caliper while hanging from the hose. it sustained damage. replaced line all fine.the brakes are no longer pulling but i'm getting a c1155 left front abs sensor. it's intermittent comes and goes.i thought it's supposed to come on and stay on.
