I imagine I may have to replace Brake line coming out of caliper because of Rust. I have been spraying pb blaster and doing some light tapping with a hammer hoping to start loosing up rust/bolts. Have not attempted to remove.
Any suggestions on proceeding? Don't know if there is something else I should use in hope of freeing up rust.  |
your question / issue is confusing.
to remove the wheel sensor in the front hub you must remove the front rotors. do you have these removed ? sensor held in by allen screw.
the caliper pins did you remove them ? need torx bit, with these removed and the caliper brake hose removed see if the caliper piston moves freely.
with the abs sensor removed does the grease look like rusty color if so the hub is bad . if the grease is bluish color its good.
most likely the ABS sensor mounting suface needs filing , to smooth out the rust then install and check for 380 mv ac minimum with your spining the wheel hub.
make sure you don't allow brake fluid to drain out or the abs pump will get air in it !
