I hit something and somehow managed to break a brass fitting connecting the brake line to the caliper. Lost all my brake fluid on the ride home. I removed the caliper, replaced the brass fitting, reconnected the brake line, filled the brake actuator, bled the brakes, checked for leaks.
The brakes still seems sloppy and the actuator moves a lot. When I disconnect the reverse plug/power to the actuator there is no engagement of the brakes to stop me from backing up.
Did I damage the actuator by driving with no fluid?
Maybe I still have air in the system?

Anyone have a troubleshooting tip or suggestion?

Thank you.

Not an expert, but it's not a very complicated system. No fluid shouldn't affect it other than not working while empty. Has to be air, or you have filled it and bled it with coupling compressed so it's got no way to build pressure and compress more??

I would test the reverse solenoid just to be sure its not bad and also there should be a spot ontop of the actuator where u can insert a large flat head screwdriver and actuate the brakes by working it bqck and forth. It definitely sounds like you still have air in the sustem. Rebleed them and check it again. Good luck!

Thank you all for the help. I bled 3 pints through the system, checked everything I could, and tested the reverse solenoid. Something internal at the actuator must be damaged from the lack of fluid while returning home from the coast.

If the brake line goes down one side of the frame, and tees across to the other, start your bleeding at the wheel farthest from the actuator.

Just an update.
It was the master cylinder.
Back in business for now.
On to the next project.
Thank you for your help.

As of now my brakes are not working either. System was bled but it seems like I also have a bad master cylinder because the system will not hold pressure. the brakes will try to catch for a second and then nothing. Also when I hand pump the brakes it seems like there is little resistance to push the fluid. I can also see bubbles come up from the reservoir whenever I actuate it with the screwdriver. There is fine metallic shavings all in my brake fluid, which tells me something has broken down internally. With that being said, how hard was it to change out the master cylinder? How long did it take you? Thanks.
