Someone else has probably already commented on this but as a bike mechanic I've done many many bleeds and a little tip is when doing a lever bleed it also helps to tilt the lever both up and down 45 degrees while pumping it as bubbles will sometimes hide along the edges of the master cylinder. PS...you guys rock!! Cheers!!

@sydfixesbikes 2 года назад

Great tip!

Dude an year later, different bike (Gravel) That solved an issue i tried to solve multiple times with an full bleed. Cheers.

@LittleStar261 5 месяцев назад

I wondered where those bubbles were coming from. Thanks!

@pkelly20091 4 месяца назад

The lever wasn’t full with oil. The mineral oil entered the lever replacing air with oil. The replaced air exits as bubbles.

@veli-pekkaporrassalmi3135 3 года назад

I love it how you guys didn't edit out all the small mistakes. Typically maintenance videos are about perfect execution of steps but in reality, we all make mistakes. We also learn from our mistakes and we can learn from other people's mistakes too. I think one of the greatest fear of new comers is "What if I make a mistake". This video shows that it's ok if you make a mistake, just learn from it and get it right the next time. Great content!

Hey guys, just wanted to say that your new channel is soooo helpful. I love the format. This vid especially, as in the past I'd just thought, "Brake bleed? No way. Down to the bike shop I go, that sounds too technical". They're really confidence inspiring vids, so thank you!! And it's also super useful to hear stuff in layman's terms too rather than all the technical jargon that often makes a job sound way more complicated than it actually is. Keep up the good work yous two!

I'm not the first to say this but THANK YOU for this video!! I've had a kit in my garage for maybe 2 months now, but haven't had the courage to tackle the job for fear of messing up the whole brake system and being without my bike until the shop could fix it. As Syd said, this completely "demystified" the process and everything went smooth as silk. Got out tons of bubbles on both brakes, but no dark stuff... woohoo! Thank you thank you thank you. Can't wait for the full bleed vid!

This was awesome, thanks. I've happily changed brakes and bled everything on my car and motorbike but pretty new to bicycling (as an adult anyway). Bike brakes are so much smaller and more integrated than on vehicles, I was a bit confused but I feel much happier understanding the fill / bleed point and how easy it is. Great video.

@allanridesbikes5856 3 года назад

Alright. I'll finally give this a try. I've been waffling on whether or not to bleed my own brakes, but I'll start with a lever bleed. Thanks as always.

Thank you so much for this video! It immensely helped me. My rear brake was near totally useless and I couldn't get any time from a bike shop to look at it because of them being booked up for weeks in advance.

Here is a tip that helped me. When you pour the mineral oil, turn it so the jug is sideways. This way it will pour easier without the “gulps”. Its like pouring windshield washer fluid into a car. Thanks for the great content on this channel!

I barely ever comment on youtube vids but this one has been so helpful that I feel I have to. I just followed this video to do a lever bleed on newly installed Shimano GRX STI brake/shifters (road-type hydraulic brakes) after shortening the lines and it worked as brilliantly as on mtb brakes. The only difference is that for road brakes you need a little adapter thingy to screw the bleeding funnel into place. Thanks for all your vids - insightful, concise, entertaining and very well made. This one and the one on how to set up tubeless tires with a floor pump are my current favorites. They both meant breakthroughs in my bike-building project! greetings from Belgium!

@IBCMTB 3 года назад

Tip! If you're just doing a lever bleed, maybe best to pull pads and put a bleed block in so you don't overbleed the system. The last lever bleed I did was with worn pads & wheel in, meaning the pistons were already extended a bit. When I later replaced the pads & needed to push the pistons back in, it actually over-pressurized the system & I had fluid blow out the relief valve of the lever (as it had nowhere else to go). In hindsight, an alternative solution to this would be connecting the funnel before pushing the pistons back in, giving the excess fluid a place to go.

@Sandriell 3 года назад

If you put a bleed block in then you are fully compressing the pistons making the total volume smaller, then once you put the wheel back in and the pistons readjust to the much thinner rotor you are increasing the volume and will be back to the same problem of not enough oil to fill the volume. You actually solved your own issue in the second part of your statement though. When you change to brand new pads, screw in the cup with oil, remove the old pads, compress the pistons, install the new pads, install your wheel, then finish the lever bleed.

@matthiassvoboda527 3 года назад

@@Sandriell The brakes and reservoir volume are designed to be filled with the bleed blocks in place and can accommodate worn pads. If you overfill the brakes, on the other hand, you might not be able to change brake pads on the trail! That might not be a problem on a short ride, but if you spend a day in the mountains it is a no-go.

@leepowelldev 3 года назад

Completely agree with this - this video basically shows how to overfill the system, which is why the lever feel better afterwards. The air coming out is a result of the pistons advancing and the additional space being taken up by fluid in the master cylinder. IME if you're getting to the point of the lever being back at the bars then either the pistons are sticky and not advancing correctly, or you have wear on your pads or rotor.

@peterpage9017 Год назад

@@leepowelldev that's the whole point. To bleed the brakes to account for the wear of the pads and rotors

@peterpage9017 Год назад

Yup you did the right thing. It's like on a car when you top up the brake fluid when the brake pads and rotor wears down, creating more travel in the system. But when you push the calipers back you take fluid out of the system so it doesn't over flow.

You guys have great camera presence (well, Syd at least, but Macky is great at explaining stuff in an easy to understand manner!) and I'm keen on learning along with you! I got my first ever mountain bike less than a month ago and am really stoked to learn about maintanance along with you! :D One suggestion - since Syd is a pro biker, maybe you could consider starting another channel dedicated to learning riding skills? With your approach to explaining I think It'd be cool to watch! Hope your channel does well and I'll keep my eyes peeled on new videos! Thanks again and have a good one! :)

@jeff7086 3 года назад

That work well for a front brake bleed. As Macky said the rear is much longer, also it has more bends and spots for air to get trapped. So a tip for a rear bleed is to hang the bike vertically so the air had a easier time moving up to the brake lever. and then same process. sometimes unbolting to brake caliber and putting a bleed block in makes the line straighter so air is easier to purge.

@patrikmoller3643 9 месяцев назад

Thanks for great advice, I'll try this on my bike next maintenance 😃 A bit of advice for you, when pouring from a container like the one with the brake fluid, tilt it 90 degrees to get it closer to the funnel and minimize the risk of spilling

@joeyc8546 3 года назад

You keep making these look so much fun to do. Will have to do my rear brake, lever goes to the bar after sitting at work for the day. V annoying as that isnt cheap, is the Deore XT. The front i just changed cos the XT piston was contaminating the pads and discs so that is just a Deore. Would be interesting to see a calliper maintenance if you do them?

@gepardtilly 3 года назад

I followed your advice and managed to make my brakes solid and sharp again! Saved me a 2months waiting for appointment. Thank you! When I removed the nut, there was no oil visible at all in the lever. And then I had to keep on pumping and rubbing the cable for like 20 times, bubbles coming out like crazy, until finally it became solid. I wonder where all that oil goes? I haven't seen any leaks either on the cable nor on the caliper... I had cut and installed the cable myself for the front brake, 2350mm custom length (cargo bike). The rear brake was still original factory sealed (watching a couple of RU-vid videos). Shimano Zee. I couldn't see any oil in neither of the brake levers after taking out the nut.

@sydfixesbikes 3 года назад

You should definitely check your brake pads! Low oil is often a sign that the pads have worn out!
