Any way to determine best of old, out-of-car master brake cylinders to use to replace one that's obviously bad...leaky, etc.? Awkward, messy job...don't want to just try one, then another, and so on.<br></div><div id="yui_3_16_0_1_1490652756999_28288"> I may have 6 or more cylinders...all removed from cars ages ago when the cylinders worked just fine. A couple cylinders are in thin plastic bags, one actually has silvery metal still on it....not just rusty and greasy.</div><div id="yui_3_16_0_1_1490652756999_28325"><br></div><div id="yui_3_16_0_1_1490652756999_28374">PS: Safe Driving Advice: A defunct master cylinder still stops the car...but nothing like it should.

This is BAD safe driving advice, but...working so far.<br></div></div></body></html>
