Well if he doesn't do it by the 8th then it will get done that weekend. Probably need new shoes by that time depending on the severity of the leak. I went 2 weeks with a leak before being able to fix it, 2 weeks from when the problem was noticed.I'm guessing the leak has been there for a couple months. This soaks the shoes in fluid, eats the paint off them and makes a mess of things. I found my recipt from when I replaced the first wheel cylinder and put new shoes on my car. $28. And all the parts were in stock.
