Waiting on parts for our money pit LOL

Waiting on parts for our breaks for the motor home... We just bought tires 3 weeks ago so we could make a trip to the coast with my brother and his wife. On the way home while checking out other campgrounds the squeak, squeak, squeak started :-/so another what, maybe $500.00 bucks out the door.... I am not really sure how much it will be ..I will update after I find out LOL its so worth it though I love being able to just jump in and go ...
