Brake Disc Measuring tool

Your car has several, a dozen or so different sizes of brake discs and you don&#39;t know what yours is? Thanks to this simple tool you will be able to measure them precisely, all you need is a caliper. The elements are modeled from size 100, so that you can easily measure smaller brake discs, e.g. 180mm from a motorcycle, because standard calipers support up to 150mm.A good 3 strokes with a file are enough to smooth the surface and remove any defects so that everything is flat.Why did I do that? Because too loose a connection will cause the elements to tilt a lot and the measurement will be inaccurate. Assembly and disassembly of elements when the surface is smooth is also much easierthe next step is to fold it to a sufficient length as in the pictureWe zero the caliper on the wallwe lift the entire measuring tool up so that it adheres well to the hub and is in line<figure class="im
