It is a 2003 Dodge Stratus Gt
I have put new calibers and new drilled and slotted rotors and new brake pads even drained & filled master cylinder but once in a while it will pull to the right ?? Is it possible that the brake proportioning valve is hanging up???
Thank you

 

I would check the suspension and the steering rack mounts

 

I Agree !!!

 

And tire pressure. Swap tires left to right and see if the problem changes. "Wiggle the crap" out of stuff up there looking for looseness

Have someone work the pedal, pump a little out each left/ right bleeder, and "feel" for difference in flow. Line pounded flat by damage?

 

Check the front suspension and lower ball joint. The lower control arm mounts were a problem on these cars. So check that real close...Bill
