I have a used hyundai accent 2014 . 80 000 km . how can i check my rear brake drums if it must be replaced ? I tryed but the drum is stuck . and how to do a full brake fluid flush easily ?

you have to get the drums off, try prying them and hitting them hard with a slede hammer so you can check them. Or pay a pro with a puller tool.

okay thank you , i will try ?
