I have a 2004 Nissan Sentra and I just replaced the brake shoes and brake cylinder for both the rear brakes. Now, the brake shoes rub against each drum, not allowing the wheels to spin freely. Both wheel cylinder pistons are sticking out further than the old ones did.
When I apply the brakes, the pistons come out farther, and retract, but not as far as they should. When they retract, they come to the same stopping point every time, but it’s not far enough in to allow the wheels to spin freely.
When I push the piston back in, they come back out to where they were before.
I’m guessing the problem with is the wheel cylinders pushing out too far, causing the sheos to rub against the drum.
What do I do to keep the brake shoes from rubbing against the drum?!?
The star wheel is fully retracted, but he proble remains. Good idea, though!
Should be a star wheel to ajust the rear brakes between the 2 shoes.
Your car’s rear drum brakes are not self-adjusting. There is an adjuster screw at the bottom of the drum plate that will allow you to adjust the pitch of the new shoes to give proper braking.
Edit: Huh. I’m assuming that you completely bled the system and replaced the brake springs?
Could be the parking brake is now hanging up and causing the shoes to be against the drums all of the time now. Sometimes when you take shoes off the cable gets twisted and causes the parking brake to engage slightly and you can’t get the shoes adjusted with that star wheel. Remove the parking brake struts and see of that cures the problem. If it does, your parking brake cable got twisted while you were replacing the shoes. That happened to me and I just never put the parking brake struts back in because I figured the cable replacement (in my case it was rusty) would be too much of a hassle.
Not sure if that will help you, but it was a thought. Good luck.
