How to Bleed Shimano Road/Gravel Hydraulic Disc Brakes | BleedZone Kit

[@bleedzonekits]

If you have brake pads past half life, we recommend that you keep the funnel on the brake lever at the end of the bleed process, clean the caliper, return the brake pads and wheel, and then press the lever a few times until they are firm. Then, remove the funnel from the bleed port.

Awesome video! Short and to the point. Many who post "how to" videos act as if they're amateur film producers and overexplain everything!

[@bleedzonekits]

Thank you! That means a lot!

[@nelsonmongiovi3539]

The best and most simple video I’ve seen to date. Thank you !

[@bleedzonekits]

Sure thing! Glad to hear that and happy riding :)

[@cyclingadventure1804]

Best explanation of the bleeding process to date. Thanks.

[@bleedzonekits]

Aw thank you!! So happy to hear that :)

[@NoahStephens]

Hey Libby. Your video sold me on your kit. If you are conscientious enough to make this tutorial, I trust are just as thoughtful about how your kit is put together. Cheers!

[@bleedzonekits]

Thank you for your kind words! We are very thankful this video was able to help you make a decision on purchasing our kit. Happy riding!

[@robertz5243]

Thanks for the GREAT Bleed Zone Kit! Just bled my Ultegra brakes with your kit and this video. Saved me from waiting on the LBS which is two weeks out on any work. It took 15 minutes to do front and rear, with pad replacements, and I’m ready to go! THANK YOU!!

[@bleedzonekits]

YES, of course! Super glad to hear the kit worked well for you and saved you time :)

[@robertandrews3055]

Awesome, simple, straight-forward video!

[@bleedzonekits]

So glad you enjoyed our video! Thanks for commenting!!

Best bleeding Video so far. 😊😊 Thanks

[@bleedzonekits]

Aw, thank you! 😊

[@filipog4]

Very helpful video and nice voice of the girl from the movie, I like her! :)

[@bleedzonekits]

Hahah, thank you!

I just mounted a new 105 on my gravel bike. Both levers feels spongy, long stroke, after following the Shimano assembly instructions. I will give this a try. Great video with super sharp pictures. Thanks!

[@bleedzonekits]

Awesome, glad you liked our video

[@fabiopunk1661]

@@bleedzonekits I followed your instructions, no bubbles come out anymore but both levers are very soft. They improved but still the free stroke is very long. I wonder what to do. I think I tried everything.

[@bleedzonekits]

@@fabiopunk1661 We’re sorry to hear that! Did you use the bleed block? Our suggestion is before removing the funnel to put the brake pad, all the caliper parts, and the wheel back, and then pump the lever until it’s firm. When the brake pads are worn out, you might need extra fluid and often bubbles could be trapped at the lever. Let us know if that works for you.

[@fabiopunk1661]

@@bleedzonekits the system is brand new. yes I used the bleed block. I will do what you say: removing the funnel last. Indeed I removed it before mounting the parts on the caliper. Thanks for the feedback!

[@bob-ny6kn]

Thank you for the succinct instructions. It helps so much to keep it simple. Not so sure about using the box end, but hey, ya gotta live life to the fullest (full disclosure: I'm an open ender). I will be looking for re-supplies soon.

[@bleedzonekits]

Aww, glad to hear that

[@rodcosta2345]

Anywhere I can purchase the funnel adapter by itself? My kit didn’t come with one.

[@bleedzonekits]

At the moment, we don't list the funnel adapter separately, but if you contact us directly at [e-mail], we will be able to sell you one!

[@jeffreydeleon5630]

The bleed block that was provided with this kit did not fit on my shimano 105 caliper

[@bleedzonekits]

Our bleed block is designed to fit all mountain bike brake calipers, but we are so sorry to hear that it didn't work for you! Was the bleed block too small or too large? If you can message us directly at [e-mail], we can try to troubleshoot for you.

[@Bradbajc]

Does this process work with newer shimano components? ie. ultegra 8000, dura-ace 9100

[@bleedzonekits]

Yes, this process works with newer Shimano road/gravel hydraulic brakes including Ultegra 8000 and Dura-Ace 9100.

[@JamesBriano]

I'm using Shimano 105 and can't figure out how to insert the bleed block-it doesn't seem physically possible.

[@bleedzonekits]

We’re sorry to hear that! Our bleed block should fit Shimano 105 brakes. Could you send photos of the issue you’re having to our support email [e-mail] so we can better help you?

[@kapualanibrown9376]

I did not have a 7mm wrench so I went to Home Depot to buy one. But it turns out it is not needed for Shimano 12speed brakes They use a 3mm Allen wrench for the bleed port. Maybe you should update the video to prevent others from buying unneeded tools.

[@ErnestVillalon]

I just reviewed the shimano bleed instructions. It seems that yours is missing half of the steps

[@gilletteguy787]

Thats true but with the Shimano way take so much time i have this kit and use it like she told in the video without any issues.

[@bleedzonekits]

It’s a good idea to review the brake manufacturer’s instructions on bleeding your specific brake model if you have additional questions. However, we have found this bleeding method to work the best.

[@MrEndocytosis]

Great video, great product! But what I really want to know is the story behind the host of the video, are you the inventor’s daughter? Are you the inventor? You remind me of my daughter’s friends. Either way, great presentation!

[@bleedzonekits]

Thank you!! I'm the founder of BleedZone, but my dad and I work together, and you can find the full story on our website here: www.bleedzone.com/pages/our-story.

[@SeantheRD]

As someone who has bled a lot of hydraulic brakes, I must say this is an overly simplistic video and skips out on a few very important steps. Only under perfect conditions will just doing this procedure give you good results

[@bleedzonekits]

Hi, thanks for your comment! We really appreciate the feedback. What other steps would you include?

[@SeantheRD]

@@bleedzonekits the levers should be rotated to have the port at the highest point in the system. You can also rotate the bars at multiple angles to get additional air out of the system. The most important one is when you are almost done, hold the lever and quickly open and close the port at the caliper to push any trapped air out of the lower end of the system.

[@bleedzonekits]

@@SeantheRD While we haven’t had issues so far in bleeding brakes with our process, those sound like useful tips to remove any trapped air out of the system from both the highest points and lowest points of the hydraulic system. Thanks for sharing!!
