If your rear wheel cylinders are leaking, they will cover your shoes in fluid. If you stop medium-hard to hard, the fluid will instantly boil and cause the brakes to lock up. This can be VERY dangerous, especially if you happen to be in a turn and it happened. fix it as soon as you can...and after you replace the wheel cylinders, if the shoes did get saturated with brake fluid you have to raplace them too. You can not clean the fluid off them and even tho new fluid is not leaking out, the shoes can still lock up like described earlier.
