The brakes pull right when driving above 35 MPH and braking to slow. The car dips right, wheel turns. Then when letting off the brakes, it jolts back to the left, pretty drastically.
XC90 V8 with about 145k
The lower control arms are new and have new bushings (I posted on another thread about that...). I originally replaced the left side first and discovered the pull, then did the right side thinking it would solve it but to no avail.
New tie rods, was aligned. Car drives straight down the highway. I think I need another alignment after doing the right side control arm but the pull really only happens when braking, so thinking the brake system here.
New pads - old rotors.
I bled the left side caliper thinking there may be air in the lines after I compressed the caliper for pads. Will do the right side to see if that changes anything. After bleeding the lines, the pull went away! But now we can feel it again after a day.
So could it be there is still air in the lines? Or could air be getting into the lines somehow? What are the symptoms of a bad master cylinder?
My thoughts for what could be wrong:
Seized caliper (though I didn't see any issue when installing pads)
Sticking caliper pins
Air still in the lines, need to bleed car fully
Pinched brake rubber flex line (this could have happened when doing the other work I did)
Master Cylinder (could it be diverting fluid one way more than another?)
Some less likely culprits:
Rotors (if bad, would cause a pedal vibration)
Rear Control Arm Bushings (I read that bad in the rear can affect the front but wouldn't think it to be as drastic as it is under braking)
Any thoughts? Experiences with this sort of thing?
