Lots of people (including myself) miss the point where you put a strap on the lever then open and close the bleed port. This is vital for a firm lever! If you miss this point you'll have a brake with no air but not enough fluid and pressure to give a firm feel.

Greetings from Bucharest România 🇧🇪

Hey dude, just saw your clips on de- airing hydraulic brakes. I got a good laugh. Wasting of time and money. I have been doing major brake service for trucks and cars. I just did my brakes for my Cannondale. Just top up from the top and release from the bleeder below. That's it. Less then 3 minutes. The lines are packed and good to go.

Anyone else caught out by "bring the lever away from the grip as far as it will go"? Turns out my lever fully detaches! And it feels very difficult to reattach. Yet to resolve, but hopefully I can work out what to do soon. As with everyone else, otherwise immensely grateful for this and all of your videos!

Kit paid for itself after two bikes. I'll be doing this every spring. Got the process down to 15 min. My favorite feature of the kit is the stop plunger. Though make sure to pull it out before pushing fluid up from the caliper, launched the plug across the garage lol

After doing the bleed I like to put a little positive pressure in the system with the syringe. I can adjust the travel of the lever before engagement this way. The Shimano adjustment at the lever doesn't do squat and I hate a lot of travel before the brakes engage and having to keep the levers so far from the bar.

I thought I had it rough with my road bike calipers. My condolences.

Il profesore 👍

Love all the Park Tool Videos! Greetings from Germany where we love precise engineering-Instructions! I do have one question: I have Shimano SLX M7100 brakes. After the whole process, my front brake lever is responding super directly/sharp as I prefer it to do so. My lever for the rear brake is responding slightly softer. I read a few times that this is very often the case, that rear brake lever is always a bit softer when braking. Is that true? Or is it more likely that there is somewhere still some air bubbles hidden. The only "mistake" that i can come up with is, that my bledding nipple was facing to the ground when I did the part with quickly opening and closing the bleed nipple while a strap is pulling the lever. But the syringe was facing upward just like in the video. Might this have been a factor, why the rear lever reacts minimal softer/less sharp After the whole process? Thanks in advance!

brahhhp! thank you!

Brilliant! Thanks!

Certain lever set screws / bite point adjustment screws, when set to their maximum extent, close the hydraulic system. Find the max point as described at 2:04, then reverse a turn or two to be safe. Your shop floor will thank you.

Because you already have the lever on that side as a pump. And because syringes don’t pull a vacuum very well and if they did it would cause bubbles, rather than bleeding them out.

In my humble opinion : too many tools and steps. The syringe's step of pushing oil from caliper to oil funnel could be skipped as long as the next step is gravity bleeding when you get rid of any dirty oil in that plastic bag. And I dare say it is easier to remove dirty oil at the lowest point and not the other way round. However, very informative! So thank you for your efforts

Honestly while this is a great video, it's over complicated. I could see doing this if you can't get the normal version to work. Lookup the shorter shimano bleed videos, one of Santa Cruz's race mechanics has a famous one. It's way easier than this and almost always works. But for a total technical process, park went through literally everything.

When the caliper work is done, do you put back the brake pads and the front wheel right away or after finalizing the lever work?

Thank you, this video has been extremely helpful in convincing me not to get hydraulic brakes.

You are unsure? Did you happen to go to the manufacturer's website and read there version of the process? It is exactly as described here. Step 5 on and everything. He's not complicating it, he's following the manufacturer's directions. We could get away with it without doing a gravity bleed, but when you're a major company like Park tool putting a video up about how to, it's best not to contradict the manufacturer.

Are we supposed to do the bottom to top bleed (step 4) and the top to bottom bleed (step 6), or are those intended for 2 different systems? In other videos I see people doing one type of bleed or the other, then going to the brake burping step. This video seems to suggest that we need to do both... is that correct?

That was a rocket science

@simonm1447

2 жыл бұрын

Shimano also has a good manual for this procedure, the video looks more complicated (since it covers different brake types) than it actually is. Hydraulic brakes using mineral oil (no Dot4) don't need bleeding really often, Dot 4 mixes with water (from humidity) over time but mineral oil mixes only marginally with water and can be left in the brake for years. Since it's normally a closed system you typically don't get air in as long as you don't disconnect brake hoses. Especially simpler models like the MT200 are also simple to bleed, they adjust the play of the pads by themself and if the pads are worn you just have to push the piston back (for example with a screw driver between the worn pads) and put new pads in.

Do a video for Magura brakes!

Once flushed all new fluid in theres no reason to use waste bag. It's better to use a hose attached to syringe with top off to flush air out of caliper. As this allows drainage hose to stay submerged. This will prevent any air from back traveling into caliper and cleaning of a waste bag!

I've got a question. Watched quite a few vids on this and nobody mentioned bringing the lever outwards. What is the reason for this ? Trapped air ?

Do you think you can use normal mineral oil that you can get at the store?
