Drilled Rotor | Rotor Disc | Flettner Rotor | Rotor Replacement

If you want to purchase drilled rotor brakes but is out of budget, you can actually try to make one by yourself as a do-it-yourself project.  Of course, you will require your old-fashioned rotor brakes.  Once you have your master pattern ready, re-produce this you can use as working templates.  Next, with the aid of a compass and some draughting tools, make the pattern of holes that would be drilled on the rotor.  You need to remember that the holes must be properly spaced and with even gaps in between.  Note that if you put the holes so closely together, it can actually cause breakage of your rotor brakes.  Just imagine your brake pads pressing against your drilled rotors and the amount of pressure applied must be seriously considered.  If the holes are drilled near each other, then the tensile strength of the material in between each holes becomes lesser making your drilled rotors weaker and breaks easily.

The next step to this project is the actual drilling of the holes onto your rotor brakes.  Before proceeding, you must tape the pattern onto the rotor.  It is also recommended to centre punch each hole so that the preliminary hole will guide the drill bit properly.  Actual drilling must be done with a drill press.  Remember that your rotor brake is made of cast iron or other heavy material which will be too strong for your regular handheld drill.  If you do not have a drill press, then you must take your rotors with the templates to a machine shop for drilling and chamfering.  Once the holes are drilled, then you have your very own self-made drilled rotors.
