Hello I will help you with your question,
Remove the rubber plug in the face of the rotor hat between the lug studs and adjust the shoes in so the rotor will slip over them. You will have to turn the rotor as you pull it over the shoes.
The adjuster is at the bottom of the park brake shoes, use a flat screwdriver to turn the star wheel, If they tighten turn the wheel the other direction
Let me know how I can help you
I knew of the star adjuster. My problem was with a very large ridge of rust.
Yes but this is why you need to bing the shoes inn as close as you can and then you twist the rotor to work through the ridge of rust and pull the rotor over the park shoes. In extreme cases the pins that hold the shoes will need to be cut to allow them to come out a little so you can dig from the back and pry the rotor off the shoes.
Have you replaced the rotors?
If you have great, let me know if you have further questions. If you have not try what I posted above and let me know how you built up that much rust on a 2010? Was this submerged?
