Kia Maintenance Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
I agree that the problem is in the right brake shoes. Have the shop that installed them check their work and the wheel cylinder at the same time. There is a rubber boot on the cylinder that if you pry it back should only have a thin film of brake fluid on it. If there is enough fluid to drip when the boot is pulled off the wheel cylinder the wheel cylinder has failed and needs to be replaced. I would do both sides.
This is very common on this model. (Not the brake shoes but the wheel cylinder)
Let me know what I can do to help you with this
