Hi Patrick, I just wanted to say thanks for the super clear explanation for how to bleed breaks. You've no idea how hard I've found it to find a clear explanation coupled with a nice clean video of how to do it. I wish I'd found your channel sooner. I was going to have to get the bus to work tomorrow but now I'm riding! Cheers again to you and happy new year to all at J&P Cycles. Daryll

That is what the one way bleeder valve is for , so you don't have to close the bleeder screw every time someone let's off the break lever , this is why this tool was invented , now granted he might be just being Xtra careful not to introduce new air in the break line , but with this tool you should be able to leave the bleeder valve open on the caliper, pump the break lever being careful not to run out of fluid in the reservoir up top , keeping it filled and just make sure on the last pump to go ahead an tighten your bleeder valve screw before removing the one way valve from motion pro , just on the last step for precaution.

Thank you for the information.

you guys are awesome, looking at being a motorcycle bike mechanic and your videos show me a lot!

Great video! Very straightforward and informative.

good detail and simple to follow 10/10

Thanks! Much easier than I thought it would be.

Very good, educational info to have.....Thanks for sharing it with us!

the video really helped us sir. thank you so much

Ty for the upload I really appreciate the clean video

Best video i have seen yet!

thanks.. i had the same issue and now it's solved.. thanks again...(Y)

On a complete reservoir replacement how many “strokes” does it typically take to bleed brakes ? Last time I did it I didn’t think I’d ever get them bled

Great vid. 👍

Thanks for sharing 👍

If you have this one-way-flowing hose, why would you need to close the bleed screw everytime? Shouldn't the hose prevent the fluid/air from being sucked back when releasing the lever?

Good instructions but my issue is different, I have an 05 Wide Glide and put a 09 Fatboy wheel and fender on I collapsed the caliper by opening bleeder screw so I could center tire and rotor and bled the front brakes the way you showed but I can’t get caliper to pump up. Any suggestions would be appreciated Thanks!

Good video

Question. I am changing my bars on a 2021 road king. I am not replacing the whole brake line, just using an extension line from fat baggers Do I just pour new brake fluid in the reservoir ?

Ok this is an out of the box question. I have a Royal Enfield Thunderbird 500. I have had this issue for a few weeks now. Air gaps into the Brake Lines, the rear Brake Lines. Ok so heres the deal... I have a Breather Valve under my Inlet Manifold at the Engine. Its Constantly sucks in air. Could I possibly use a hose, run it from the Air Valve to the Air Nipple on the rear callipers? Effectively that way, it would suck out some Brake Fluid and Air from the Rear Brake Line. Let me know if anything I said makes sense at all? PS - Yes, my brake pedal felt spongy in the last couple of days and is now completely dead with no resistance at all.

Hell yeah thank you for the good info..i swapped out my front break pads and got air into the line and couldnt get the air out...i drove 11/2 days with no front brakes..scary shit but its my only vehicle so i didnt really have a choice..then today after searching and watching videos i finally came across yours and got the info i needed to bleed the air out of the line correctly and without costing but only a couple bucks..thanks alot i really do appreciate it.. I subed also

I have a Yamaha FJR, the front and back brakes are combined, or linked to each other. The back brake peddal has to be pumped several times in order to work. Do I bleed this system the same way ? Any ideas why I am having this problem ?

What's the point in using a one way check valve if you're going to manually bleed the system, the whole point of it is to keep the nipple open while you pump the lever pushing the fluid through solo.

Very informative.How about the rear brake?Do we bleed it also 2x a year same with the front?

Great job thanks!!

my type of vid no bullshit straght to the point thank

Great vid... will def be doing this!!!

Nobody seems to know about One-Way/One Man bleeder vavles. They cost $5-6.00 bucks at any auto supply. I got mine at Napa. This gizmo allows fluid to exit the system but won't allow any Air to be sucked into the system. Keep the reservoir full, pump lever till you only see Clear, Clean fluid (no bubbles) then shut the brake valve. Top off the Reservoir (don't over fill) and put on cap/lid. Test ride with hard braking and check to see if you need to add fluid. Done

Dose this work for cars also?

That's one gorgeous dyna

Thanks for the video. What about the XL1200R with two disks in front? Which one do I bleed first?

I just gravity bleed, no need to pump lever. Open the bleeder and let it drip. Keep a close eye on the res level and get it as low as possible without uncovering the outlet before adding fluid. This will keep the fresh fluid from being mixed with the old. Bleed until the fluid in the plastic line comes out clear. 1 man and a piece of cake.

Can you help me figure out why I have a caliper leakage problem I found a caliper leaking on the bike put new seals in it put it back on it continue to leak bought brand new calipers put them on same side of the bike the caliper leaks again with brand new calipers I'm thinking maybe I'm bleeding it wrong or doing something wrong?

Great. Video. On. Brake. Line. Bleeding. Conan. Grizzard

how can i adjust the air to gas ratio on a 388 s&s shorty carb

since it is "one way out and no air in" it think you just have to open the valve once, pump the lever several times and observe if there are no more bubbles coming out with the fluids...put some new brake fluids...pump again...no more bubbles then close the valve...is that simple Sir?.....

Will this work on my CVO with abs?

Is it necessary to replace the master rubber diaphragm after bleeding the brakes. I am having trouble finding that part for my 2007 Honda Shadow.

Great bike.

I replaced the hose from the master cylinder to the splitter on my 2001 Vstar 1100. After bleeding the brakes. I'm not getting air bubbles in the clear hose on either side, yet the lever goes right to the grip. I'm not sure what I did wrong.

I cant find anything on changing a brake light switch. Im self diagnosing. 09 street glide. Cruise not working and btake light stays on. I figured out the light only stays on after using the rear brake. Rode 20 miles... o ly usong front and cruise worked as well as brake light normal. So i bought a rear break light switch... any help?

👌

I thought you'd first pump the lever, hold it in, then crack open the nipple to bleed, tighten nipple then release the lever. But in this video the line was cracked open before the lever was was even pulled. Is my thought of pumping the lever even before opening the nipple incorrect?

That’s perfectly fine but you should change the title to promote the motion pro valve because otherwise it’s backwards.

I have always seen or heard that you pump the break first, then open bleeder. Am I backwards, or can you comment why you open first and then press lever?

Hi have done the bleeding front brake but my clutch still spongee

You could save $20 on the check valve rip off thing by using the bottle and hose and just elevating the bottle above the bleeder nut. Air will flow up and not down back into the system. I am surprised that pro's haven't caught onto this yet?

wait, so on other videos they do this order, "pump lever, build pressure, hold lever, open valve, bleed, close valve, release lever", but you did "open valve, hold lever once, bleed, close valve, release lever" which one is right?

Followed these instructions but still have squishy front brake handle. When do you know if the master cylinder is bad? Bike is 18 years old.

for what you need valve if you close everytime bleeding pin?)))

why not open a little & just fill reservoir as it empties ?

Once or twice and year??? But Harley recommends every 2 uears

When i did this i emptied the fluid and pulled the brake and it squirted fluid and the master cylinder was stuck can this be fixed and how?

what if you have dual front calipers? you need three people?

If your check valve doesn’t prevent it from sucking air back in then what is the point. Use a longer tube and fill the bottle 1/3 with fluid. Immerse the tube in the fluid in the bottle. No check valve and no second dude necessary.

I have a vn750. Did this without the hose on the valve and its still spongy. How important is that hose?

Did everything in the video. I have a hard stop on my brake lever, but it stops about 1/2” lower than before changing the front master cylinder. Do not have to pump it up, no air. Just curious before I take it out on the road.

The check valve is the reason you dont have to open/close the brake valve, why are you doing it? One or the other is not necessary unless the check valve does not work.

What’s the point of the one way valve if your doing it the traditional way, shouldn’t this tool be used if you don’t want to continuously open and close the bleeder

Are the back breaks the same as the front ?

I have fluid in the rear break master cylender.i have attempted to bleed the rear break 6 times but little or no fluid comes out.why

Why does one of my bike's brake handles feel mushy even AFTER the lines were bled?

Bleed brakes once or twice a year? Did I hear that right?

Stupid question. Your sucking out air bubbles along with the fluid. Shouldn't you too off the M/C. I believe there is a level line inside the resovoir?

I don't have no brakes after I ride 20f replace Master cylinder and line sitting still got brakes

HI, My bike has a dual rotor front wheel, so this has to repeated for each caliper?

I bought a used motorcycle. The screws on the master cylinder are stripped pretty bad. Anybody have any suggestions to get past this problem?

I think I need to do this. My bike just lost 90% of front brake power and the lever pulls right up to the handle meow :(

Mine doesn't work well, ever hear of back bleeding?

if you are going to show us something, please, keep the camera on that spot so we can see. it's a "how to" video. thanks.

Hi

everyone uses a $20 piece of tube and meanwhile i've talked to multiple folks who just uses their finger and spend the $20 on beer. I'll go for the beer seeing as how even if i wanted the hose it would be over an hour drive.

Okay, but what about the rear brakes?

Why not show rear break bleed ??

Not everyone has a bleeder kit

Started good got real bad real quick

what is bleeding brakes?

Which Motion Pro tool is NOT made in china??

??????

Why do all you "experts" insist on opening and closing the bleeder screw? As long as the drain end of the hose is submerged in fluid, no air can enter the system. Just open the bleeder and pump away. The check valve is not necessary. Also, pumping the brakes before bleeding is a no-no. Any air trapped in the system will be agitated and make it harder to purge.

Now do the rear - LOL

once or twice a year ??????? How about every 2 years

Jesus loves you !

Now show how to do the back !

leeverr,,,,,, lehver is wot yur jacket is made from,,,,,lol,,,,buy a harly,buy the best,,,,,,,,,

The Harley pot metal reservoir is junk!

You do know motercycles have a rear break dont you

Too bad Harley can't make a decent set of breaks.

20 mnts lol

Lets sell some that does NOTHING LMAO

feel asleep, to much talking.

Another company assimilated by the Borg collective.

make sure to label bottle, some liberal might come by and drink it

lmao that tool is useless and the way you did it is time consuming
