Woodcraft Brake Light Switch

These universal switches allow rearset users to operate the rear brake light. This all-in-one unit replaces the banjo bolt that connects the rear master cylinder to the rear brake line. You simply replace the bolt with this assembly and splice the wires into your existing brake light switch. The pressure inside your brake system then activates the brake light.

Fun with the brakes I had to install the brake fluid pressure sensitive brake light switch with a new set of rearsets I purchased. Overall I am very satisfied with the product. However, I have a few items I'd like to point out with regards to the the finish and installation. Finish: As you can see from the picture, the cable protector is loose fitting and does not connect to the bolt, leaving the electrical cables exposed to the elements. I have not looked closely at the components, but I suspect dirt has made its way into the cable protector. I'd like to see this improved. Installation: If you do not know how to bleed brakes, get someone to do it for you or this will be a learning experience. I chose to to learn on the fly. Thanks to the many youtube vid's, I was able to do it safely. Make sure you look into bleeding rear brakes before beginning the project. I needed to pick up additional hardware to do the job. For me, I ended up purchasing a bleeding kit at the local auto shop. Over all the installation took about an hour, including the rear brake bleeding and electrical. June 21, 2016
Good product but careful tightening! Installing is pretty easy. It uses brake wire which you expose and connect to this product. Don't tighten too much.... I tightened too much and snapped the bolt. Did get to install and must say it isn't too hard to install on m cbr600rr. You will need to remove fairings and gas tank to install. May 22, 2016
Simple and easy to install Thought twice about buying and installing this myself. Im glad i did. It was pretty simple and easy and does the job its suppose to. Couldnt be happier with the results May 3, 2016
Perfect, works with galfer line. Honda f4i uses the coarse thread. The thing works well and it's a much better mechanism than the OEM spring/switch. I installed this along with a galfer steel brake line so I can confirm that everything works nicely. May 28, 2015
Works and fits exactly as described Works as described and fit my 2003 Kawasaki zx6r perfectly (coarse threads M10-1.25). Install was easy and plugged right into existing wiring. Only weak link was that the wires coming out of the banjo bolt seemed unsupported and vulnerable. Used electrical tape and taped it up to the protective wiring sheath. April 6, 2015
Great To Have If You Commute And Attend Track Days If you plan to upgrade to Woodcraft Rearsets and you commute on your bike plus occasionally attend track days, then you probably would want to get this simple switch so that it allows your rear brake light to work while on the street. The rearsets do not come with this part therefore you will need to get it. Since i'm going with Woodcraft Rearsets, I mind as well buy this product from the same company. March 29, 2015
exactly as advertised If you are at all competent at wiring, installation should be a breeze. In order for this product to function correctly, you will need to bleed your rear brake lines, so the installation of this product may be a little more involved than you had bargained for. Once installed the pressure switch works perfectly as long as you get all of the air out of your lines. Give yourself a solid hour for install, start to finish. September 29, 2014
Brake Light Switch Had racing rearsets on my Aprilia but the rear brake would not light up my tail light. Installed this and everything is working now. September 30, 2013
