As may of you know we are in the process of producing master cylinders. Unlike some vendors with impeccably clean "Laboratory " complete with Periodic table. This is how we get things done.
Phase 1 We have a test bed that simulates braking, and are looking to see where our weak points are. We will put no less than 25,000 cycles on this part. This will take awhile as we can only get about 200 at a time without the motor heating up, but believe this to be a very rigorous test. Phase 2 If we make it to 25,000 we will start measuring output from the pressure lines. This will be thoroughly broken in system we will be testing, not just testing with air pressure. After the final round of testing we will tear it down to determine wear on critical components and examine the seals to see how well they have held up. If they show excessive wear we will look at improvements that may need to be made. Especially so if we don't make 25,000. My only serious concern is that the metal on the test stand may fatigue making us repair it before we hit 25,000 cycles. We are currently a little less than 5000 cycles. I thought I'd share this as many of you don't realize what we do behind the scenes t o actually make the parts we all need. https://youtu.be/UskyAeVAF9Y https://www.youtube.com/watch?v=UskyAeVAF9Y |

Your test devise sounds like my heart when I wake up in the morning. (IMG:style_emoticons/default/av-943.gif)

Your test devise sounds like my heart when I wake up in the morning. (IMG:style_emoticons/default/av-943.gif) Elliot "Jarvack" (IMG:style_emoticons/default/biggrin.gif) We actually thought about the additional heat, knowing that this would exceed normal use is actually a plus for us. Also one of the reasons we wanted to do an analysis of the unit after the test. We may also go to a larger motor and let it run til it fails. The kill switch is the brake warning switch. Although I'm pretty sure the stand would fail 1st. |
