Ok so a couple months ago I hit a curb with the right rear tire going about 30 mph (stupid round about) and now when I put on the breaks I can hear a clicking coming from the right rear side. I need to replace all of my breaks anyways and was wondering what else I have to replace on that side?

 

You wont know till u pull it apart. We cant really tell ya

 

doubt you did any damage to your suspension, might have loosened up the caliper and when engaged it moves and clicks when stopped.
