<html><body><div>Yep, I did that. I had a two switches fail back to back. The first one I replaced I noticed that nothing dripped when I took out the switch of the hydraulic system, but I bled the brakes anyway and no bubbles. It was literally a few weeks later my brake lights were not working again. I found some new old stock. I put some brake fluid into the switch and then swapped it out no problems, no bleeding the brakes, and that was a couple of years ago. All good.</div><div><br></div><div class="x-apple-signature">Rye<br></div><div><br>On Jul 20, 2018, at 10:18 AM, Andrew Uprichard <auprichard@uprichard.net> wrote:<br><br></div><div><blockquote type="cite"><div class="msg-quote"><div class="_stretch"><span class="body-text-content">I would have thought you could simply swap the old one out with a new one<br>without "getting into the hydraulics" Given the switch has a head of fluid<br>above it, I don't see any air getting into the system.<br><br>Andrew Uprichard<br>Jackson, Michigan<br><br>-----Original Message-----<br>From: Triumphs [mailto:triumphs-bounces@autox.team.net] On Behalf Of Bob<br>Labuz<br>Sent: Friday, July 20, 2018 9:27 AM<br>To: Triumphs List<br>Subject: [TR] brake light switch<br><br>Hello,<br><br>Looks like my brake light switch is toast.<br><br>Would like to know if it is possible to convert to the later TR4/4A <br>switch off the MC by making a bracket to hold the switch.<br><br>I dont want to get into the hydraulics unless I have to.<br><br>Car is a 63 TR4.<br><br>Thanks,<br><br>Bob<br><br><br>** <a href="mailto:triumphs@autox.team.net" data-mce-href="mailto:triumphs@autox.team.net">triumphs@autox.team.net</a> **<br><br>Donate: <a href="http://www.team.net/donate.html" data-mce-href="http://www.team.net/donate.html">http://www.team.net/donate.html</a><br>Archive: <a href="http://www.team.net/archive" data-mce-href="http://www.team.net/archive">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums" data-mce-href="http://www.team.net/forums">http://www.team.net/forums</a><br>Unsubscribe/Manage:<br><a href="http://autox.team.net/mailman/options/triumphs/auprichard@uprichard.net" data-mce-href="http://autox.team.net/mailman/options/triumphs/auprichard@uprichard.net">http://autox.team.net/mailman/options/triumphs/auprichard@uprichard.net</a><br><br><br>** <a href="mailto:triumphs@autox.team.net" data-mce-href="mailto:triumphs@autox.team.net">triumphs@autox.team.net</a> **<br><br>Donate: <a href="http://www.team.net/donate.html" data-mce-href="http://www.team.net/donate.html">http://www.team.net/donate.html</a><br>Archive: <a href="http://www.team.net/archive" data-mce-href="http://www.team.net/archive">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums" data-mce-href="http://www.team.net/forums">http://www.team.net/forums</a><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/triumphs/ryel@mac.com" data-mce-href="http://autox.team.net/mailman/options/triumphs/ryel@mac.com">http://autox.team.net/mailman/options/triumphs/ryel@mac.com</a><br></span></div></div></blockquote></div></body></html>
