nikk94 Posted February 10, 2023 Share Posted February 10, 2023 Hello, Does anyone know the OEM brake hose fitting dimensions? I'm trying to add a Wilwood 120-6816 Calipers and having trouble finding the right brake hose/fitting to work with the stock brake lines. Any suggestions? Best, Nik Quote Link to comment Share on other sites More sharing options...
jhm Posted February 10, 2023 Share Posted February 10, 2023 If I understand your question correctly, the stock brake line fittings are 10mm x 1.0. When I mated Wilwood Calipers to my system, I used a brass adapter fitting to mate the OEM fittings/lines to the Wilwood brake line inlet. All the necessary specs on your Wilwood calipers can be found here: https://www.wilwood.com/Calipers/CaliperProd?itemno=120-6816. Looks like you'll need an adapter with male 1/8-27 NPT - female 10mm x 1.0. Hope this helps. Quote Link to comment Share on other sites More sharing options...
manimal Posted February 11, 2023 Share Posted February 11, 2023 Brakequip BQ187 is the line adapter you're looking for. If you end up using a wilwood master cylinder, BQ50 is the brake line adapter for those 3/8-24 inverted flare male to M10x1 IF female. ~$5/ea direct, I was able to find some locally at MFCP which is a west coast Parker affiliated chain. Midwest/East coasters likely have a similar chain. https://brakequipproducts.com/product-category/thread-changers/?filter_thread-type=standard-and-metric Quote Link to comment Share on other sites More sharing options...
