Love this app some of the things I can do in my own and some I cant do but this app is very helpful. I had to get a new rim/ wheel and I dont know if it is the brake shoes or the rim it is very hard for me to stop ( rear wheel) I found on this app on how to clean the wheel and I have done it that way. But I feel I should go back to the dealership that put my rim/ wheel on and tell them just to change the brake shoes.
