Not sure what window brake replacement I need
Hello there. Sorry but it seems our website failed to upload your photos correctly. Can you email them to us at help@swisco.com? Please be sure to include your discussion ID number D335142 so we know what discussion to reference. Note too that if by brake you mean pivot shoes, it's best to remove them from the window for a clear view. See the video on this page for guidance. Let me know if you have further questions.
Please see this picture of removed piece.
Thanks! This looks like a match for our 15-111 pivot shoe. Give this part a look and see what you think.
Note that the pivot shoe isn't what keeps the window up, but rather the springs that connects to the shoe. Make sure to check those before you buy anything, just to be safe. The 15-111 is most commonly compatible with either the 1/2" Series 160 or 3/8" Series 165, so there are two potential options.
