Great Informative Video Thank You I have. A 2018 model. I was wondering if you had one video for the the frot brakes and caliper removal

[@Killobyte]

Thanks for the comment! I have not done the front brakes yet.

I’ve watched a couple of your CX-9 videos today. Great job! You’re very thorough and easy to follow along. The video quality is also excellent.
Question: you mention the caliper bolt specs from the manual. Does that mean you have the factory workshop service manual for your CX-9? I’ve been trying to find one endlessly for the 2016-21 model years, but even Mazda HQ told me they stopped offering the workshop manuals a few years ago.

Thanks! I do not have a copy of the manual, wish I did. If I remember correctly, someone had posted the pages from the manual in one of the on-line forums.

@@Killobyte I wish I did too. I’ve always purchased the factory service manuals for our other vehicles over the years. Mazda is the first OEM I’ve experienced to keep them vaulted away 😀
Thanks for your time - good luck with your channel! 👍🏻
