How to do a front brake fluid flush / bleed |¦| Sum4Seb Motorcycle Video

#motorcycle #howto #brake
My wife and I show how we performed a motorcycle front brake fluid flush (bleed your brakes) see why it needs changed every two years! This was our first time and this is how we approached it. Demonstration and instructions included. 2001 Suzuki DR650SE, can be performed on any brand or type of motorcycles you own. All our maintenance is performed on a budget.
Always refer to the service manual if you are unsure as to how to perform the maintenance.
Thanks for watching, see you in the next one :)

Great video guys. Thanks. One good idea is to keep adding fluid and not letting the reservoir ever go empty.Totally eliminates chances of sucking in air.

[@garryoak]

If I'm only adding fluid do I need to bleed brakes?

[@tittyrino]

Garry Oak no you don’t have to.

[@Superimperator]

@@garryoak lol, no😅 just fill up, the same way you fill up your gas tank.

[@tafadzwagundapartner8062]

simple and straightforward thanks guys

[@briandavid5668]

Pumping SLOWLY is the key word, i had been pumping to quickly and it would not bleed out. thanks

[@youngman7655]

Brian David yeah same thing happened to me

[@dontanjo9872]

Same

[@adventurecraig]

Thanks for the video! Off to bleed my DR's brakes. way overdue 😐

[@arcyarcy4114]

wow thanks for sharing this video.. very informative.. a big help for an newbie like me.. more power..

[@indzone12]

Your video was a big help for me today, thanks really enjoyed this 😊👍

[@Sum4Seb]

Nice, glad we could help 😀 have a great night and *T4W*

[@canadianray9677]

Great vid! Gonna be doing my brakes tomorrow (with your help of course!)

[@Sum4Seb]

Thank you! Sorry, somehow we weren't notified of your comment, just noticed it today. We hope your brakes went well! *T4W*

[@campamitja1299]

very useful-thanx.

[@neilspiers7197]

Nice easy video to follow along with thanks

[@Sum4Seb]

Thanks for the kind comment, we appreciate it! We try to keep it simple since we don't always have all the fancy tools to perform the work :) *T4W*

[@omarkgad]

nice n clear instructions, thanks

[@Sum4Seb]

Thank you for watching, if there's something else you'd be interested in let us know :)

[@k.w.4068]

Thank you!

[@Kemrer]

Thank you. Following.

[@theweb1905]

seen people use a old rag to soak the old stuff off the reservoir... they're not worried about contaminants I guess, great video thanks for sharing

[@1balky]

Use a syringe to get it out, better than getting it through the system. There is easier and faster way to do this than showed in the video. But important thing is it gets the job done.

[@krulleman]

Nice 🤙🏻

[@NoShadowOfDoubt1]

nice video, probably pumping the fluid from the bottom is best after sucking all old fluid out. and that should also take car of all the air, which tends naturally to go up.

[@daniloenriquez3233]

Nice video and thanks...

[@Sum4Seb]

Thank you, hope it helped! We have picked up several used bikes now, and this is always one of the first things we do as we check over the bike, most people neglect it.

[@beardedcatguitarplus9485]

Great video, i need to change mine on my 84 virago. It has dual disks. Lol didn’t realize the fluid was out till I rolled the bike backwards off the trailer hahaha luckily the ramp was as wide as the trailer and had grip hahaha. I’ll be changing mine on my channel soon as well once it warms up here in Oregon.

[@Sum4Seb]

Thank you. Woah, you got lucky there lol thankfully you didn't drop it. The weather is finally in the upswing, hopefully it stays that way... tired of the snow. We'll check out your channel once or work week of over 😒

[@kenhyzer]

Good video. Should flush a couple clean reservoirs worth before finishing though.

[@mikitkharatmal5567]

Thanks guys

[@jufrimambobo4870]

hi,. you have tutorial for change brake master hidrolik and kopling hidrolik ??

[@ch3kw4]

You need to clean inside the piston Caliper because there are some dirt inside too.

[@oldfartuk]

best to always use a JIS screwdriver even if you don't have a Japanese bike ..you will find it fits much better

[@EEEBA1]

Sadly my bike was in a horizontal position for a few minutes and I can tell the front brake fluid in the reservoir was completely to one side. Do I need to bleed the line in case there is air in there? Thank you

[@bernibeckmann9753]

Looks like I'm not the only one to run the brake line outside the fork.

[@Sum4Seb]

Hi, I remember noticing that when I purchased the motorcycle. We saw the right way to route it in the service manual. Good catch

[@rossino1235]

I got air in the brake line how do.i flush it out

[@tittyrino]

A good thing to do with dirty brake fluid like that it’s just suck it all out with a syringe or any way you can and refill it with clean fluid and then start the bleeding process until clean fluid comes out of the tube.

[@jonathanvillalba3214]

Could you use a turkey baster or bladder to suck up some of the bluid from above and cut down the bleeding of the old fluid and then just put new fluid in before doing all of the aforementioned?

[@Sum4Seb]

Hi, yes definitely. Good luck

[@theblazzed2114]

That way is a bit risky to get an air in the system for me...But anyway. Do I need to change the rubber membrane every time I change the fluid.Thanks

[@Sum4Seb]

The Blazzed Hi, I did this way because I knee I was going to bleed the whole system after. Only replace damaged parts otherwise that rubber seal is reusable. Hope you have a great day!

[@MrDjslim20]

When you top up with the new, do you repeat the pump, open, close procedure until the new clean fluid comes through the nipple? I'd guess you would or it wouldn't be called a flush..

[@DonHavjuan]

Yes.

[@D3nn1s]

Four years later...

[@roogermoore1]

Why not suck the fluid from the reservoir , then fill it with clean fluid and start pumping

[@Sum4Seb]

Hi, there is multiple ways of doing this, use whichever one you're comfortable with. This is what we prefer :) Thanks for watching.

[@Sum4Seb]

Pretty Jane Thank you :)

[@kumsatx]

Is this done? I think old fluid was still in hose. You should take off that before get in new one

[@jasminewebb9]

ghnj

[@ianmackenzie686]

Aren't you supposed to continue the process while topping off res until the nipple drains clear brake fluid?

[@drdrew3]

That’s exactly what they said to do. Because it’s redundant there didn’t demonstrate the second and third cycles it took to run clear.

[@tapubratchangmai9235]

ooo yeeaaaahhh

[@rockstarmaro]

what i should do now

[@pannbanbiff]

Nice now my brake dosent work.....

[@Sum4Seb]

Hi, you can try describing what you're experiencing and I'll try to help you troubleshoot... probably have air in the system.

[@rossino1235]

+Sum4Seb so how do you get the air out and restore the brake been trying for hours

[@DeShark88]

carl rossino Unfortunately the air gets trapped as little bubbles or even dissolves into the brake fluid. The only thing to do is to keep adding fresh fluid through the system and bleeding it out from the nipple until you've completely replaced the air contaminated fluid with fresh fluid. It's a little bit like trying to rinse the soap out of a straw.

[@JonSmith-cx7gr]

DeShark88 I'm always getting soap in my straws. I always felt that rinsing them out is like trying to get the air bubbles out of brake fluid in a brake hose.

[@ADH8]

Do you do the same on twin front brake discs on a bigger bike ?

[@Sum4Seb]

Yes, same principle applies. Only thing that differs is that you want to start draining the caliper furthest away from the reservoir. You can also use whatever you have available (syringe) to suck or absorb the old brake fluid out of the reservoir. That's how I do it on my Suzuki Bandit 1250s with twin calipers on the front. Let me know if you have any questions and I'll try to answer it the best I can :) *T4W*

[@ADH8]

Sum4Seb Cheer's... I'm doing this to my Suzuki Bandit 600 :)

[@jeffreyhinman1397]

My uncle has rode bikes for years and he taught me that. He has probably 15 bikes.

[@ADH8]

Jeffrey Hinman I done it a while ago now but thanks for the tip I may do it next time :) Cheer's

[@somethingscantbefixed5933]

His voice keeps changing

[@ryandimaquibo8878]

it scared me hahahaha but good video

[@NotDolI]

After replacing the brake fluid, do not you remove the air?

[@Sum4Seb]

박성민 yes that is what the bleeding process is for. Removes air and the remaining old fluid from the lines.

[@thirteenbanger7861]

I thought you put in new fluid while draining old fluid until you see the new fluid start to bleed out then you know you have new fluid throughout the system. Cause now you have new fluid in the reservoir but old fluid in the lines

[@Sum4Seb]

Thirteen Banger I like cleaning the reservoir first... then refill it with clean fluid. Once that's done you have to bleed the entire system and make sure the reservoir doesn't get to low so that air doesn't enter. Keep it topped up as you are pumping the fluid through the system. Once clean fluid starts coming out of the bleed screw you are done. Good luck, let me know how it goes.

[@karsniv]

What about the remaining old oil at inside the caliper? You replaced the oil only in the master cylinder reservoir. It is called partial flush, not complete flush.

[@Sum4Seb]

Karthick Sri Hi, call it whatever you want to call it.... that's all you're going to get if you go to a dealership for a flush and it works perfectly fine for us. Thank for watching

[@karsniv]

Sum4Seb , yes of course I'm also noticed that this method only following in authorized service centers too. This method will works untill caliper piston O'rings worn-out. Then we can flush contaminated oil from the caliper during O'rings replacement.

[@bluedot4336]

Karthick Sri you're right.....

[@karsniv]

Sum4Seb , please keep on posting new videos 👍

[@filmfreaken]

if my res window is a bid cloudy, and hard to see through, can i open the res just to see the color, and close it back if its fine, without any problems to the system?

[@Sum4Seb]

Hi, you can open your reservoir anytime without any problems. Just make sure you don't let any debris or contaminants in before closing it. 👍

[@filmfreaken]

Thanks alot for getting back to me that quick, and thank you for this video!

[@djlancer88]

Came across a video where the dude said you should replace the rubber diaphragm every time its removed. I did not and everything works fine still

[@ahmadizzatshahmieralhamdul4926]

Alhamdulillah :)

[@hazimreitz]

It surprised me how quick it drains the reservoir as I never done a brake flush before 🤣🤣🤣 probably wasted more fluid than I should

[@Sum4Seb]

As long as it worked then it's another successful mission!

[@hazimreitz]

@@Sum4Seb YES!! yes it is!. I was bummed that my front brake got soggy. But thanks to you I got the courage to do it :D cheers

[@russellallen6828]

Allen Russell

[@aa-bc5in]

I can use any oil or not ?? The same oil of engine can I use it on the oil of break disk ???

[@Sum4Seb]

aa 232 No. It will tell you directly on the cover which kind to use. Usually it is DOT4 brake fluid for motorcycles. Good luck.

[@rockstarmaro]

my oil is not dropping from the box

[@glenmcshane3747]

I can see in the little window of my reservior that my fluid is dark brown. Need changing? The brakes feel excellent, but need changing? Nipple?! *drooling*

[@soheilrnr]

well i would change it.. nothing to lose ;)

[@o.gsepulveda8507]

I bought the dirt bike used and the brake fluid turned into. gunk how do I remove that

[@daleorr8949]

O.G Sepulveda if I was doing it I would sook the gunk out the reservoir with a syringe and then fill with clean fluid and do the process shown in the video until you see the clean fluid coming through the bleed nipple make sure to just keep topping up reservoir as you do it

[@neilhughes601]

Hi stupid question, but how do you know when all the air is out?

[@Sum4Seb]

Neil Hughes Hi, when new fluid starts coming out. I usually open the bleeding screw 7-8 times. Make sure to pump your brake a few times before riding it. You will know instantly if there is air n the system as your lever will be very spongy. Good luck ☺

[@caldwell5078]

You didn't use a new diaphragm? You always use a new one when you open the master cylinder

[@Sum4Seb]

Hi, no I did not. We always do a visual inspection for cracks, wear or abnormal deformation. We had a few DR's in the family now and never replaced one since they were all good. Could you point where it mentions to change the diaphragm every time you open the master cylinder in the service manual? Common sense and logical thinking tells me not to replace a good part...

[@Test108ryf]

how big is the hose?

[@Sum4Seb]

Hi, pretty sure I used 1/4 inch tubing.

[@Test108ryf]

ok thanks

[@anujpandey8803]

What is the size of that pipe

[@Sum4Seb]

Hi, it's 1/4 inch tubing. Have a good day!

[@rossino1235]

my grand pop went to change the fluid and emptied it all out now we have no front brakes at all tried dozen times to get the air out but it will not work ...

[@Sum4Seb]

fill the reservoir back up and repeat the procedure in the video. Make sure to keep the fluid in the reservoir topped up. You also have to make sure that the bleeding screw is closed (tightened) before letting go of the brake lever or you will suck in air. Let me know how you make out.

[@rossino1235]

Idk I tried that way we also tried a different way to leave brake handle squeezed in over night but wasn't sure if to keep master cylinder open or not

[@rossino1235]

That didn't work by the way with master cylinder closed

[@daleorr8949]

carl rossino it appears as though your master cylinder may be knackered if it’s not bleeding properly.

[@tapas1505]

I am a motorcycle lover. I want a girlfriend/wife with same kind of passion/interest/hobby for me. But rarely available. 😒

[@Sum4Seb]

Hi, we hope you find a motorcycle lover someday to share it with! Yes, you are right it's a minority group in general. We are very lucky to have each other and to be able to spend time together doing what we both love, it makes it even better!

[@m3felonia145]

Wow your voice is two

[@Sum4Seb]

Hi, yes two of us in the video. Check at 5:00 and it explains my wife is pumping/keeping pressure and I am opening bleeding valve. This is one of our earlier videos, we didn't have a tripod at the time either, she was filming me as I did most of the talking.

[@user-hy9gl7wt5j]

Please mention that you should add new oil on each drain otherwise it'll get bubbles in it.

They mentioned that. Three times!

[@Sum4Seb]

lol my wife is filming and that was her talking for a second
