How To Bleed Your Motorcycle Brakes | Dr Vstrom Brake Series

- This is a revisited topic but now available as a 2-in-1 video on how to bleed/replace the brake fluid on both the front & rear brakes, along with some very useful tips & other details.
A 2nd episode of my Dr Vstrom, brake maintenance video series that aim to ensure proper brake operation.
It demonstrates on a 2017 Vstrom & as a method, it is currently valid for most motorcycles with or without ABS brakes.
There are of course certain ABS and/or combined braking system motorcycles which are exceptions as they need special tools to run the ABS pump through a special bleeding routine cycle. However, the majority of motorcycles out there can be bled normally & in this way.
Please check with your owners/service manual first for this info.
Replacing the brake fluid is a simple yet vital task that has to be performed every 2 years if not sooner as brake fluid is hydroscopic & absorbs 2% of its volume in water every year. As a result brake fluid degrades with use & time & it is this absorbed water that eventually affects your braking system in 2 ways:
--Brake Fluid boiling point drops & bubbles form that can even pass the seals & give a spongy feel (ie Lower Braking Performance).
--Water corrodes vital braking system components with the most sensitive & most expensive to replace being the ABS pump unit (ie Several subscribers have experienced ABS pump failure because of this & of not changing the fluid regularly).

Доктор Стром, низкий тебе поклон за проделанную работу. Это подробный и невероятно нужный материал. Ещё раз благодарю.
Thank you very much my friend. Ride safe.
Hello from the United States. Thank you very much. Your video/instructions are the very best I have seen. I have seen many, but your video is the best. I’m especially grateful that it is brake fluid replacement on the newer model Suzuki V-Strom.
Glad it was helpful! Thanks so much :) and ride safe.
Great explanation. The tip at the end about leaving the lever pressed and handle bars turned overnight worked PERFECT to get that last little bit of sponginess out of my front brakes. Thank you!
Glad it helped!
I did this for both rear and front brakes, they were still little spongy. Then as mentioned in the video I kept the brakes under pressure over night and what difference it made !! Thank you so much. I feel more confident of the brake because the feel of it has changed a lot for the good!
Glad it helped Ride safe
Love how clean that vstrom is.. 😄
Very good video! The step by step is very detailed! The only video I've seen teaching how to disassemble the side fairing of this generation of V-Strom. Thank you and greetings from Brazil!
Glad it helped
i'm so glad i decided to look this up before i started messing with it, i don't have half the stuff needed. thanks for the video
Thanks :)
What’s up doc! I did it, and it went very well, both entirely thanks to you.
I modified your process a bit and zip tied a Gatorade bottle to the discs to catch the fluid in and it worked perfectly. I also tilted my brake lever back to be level, as I had it a bit too far forward to not have brake fluid spill out when I opened it and when I was trying to fill it up to full again. Haha, ask me how know, whoops. But I was prepped with a bag like you said, so no mess thanks to you.
I’ve got and Givi SR3112 and a Kappa M9 plate on the back for my top case. Wish I did the back brake fluid before I put that on, those Givi and Kappa bolts are very poor quality, and don’t like being taken off and put back on, or even put on to their torque specs the first time, for that matter.
I think I will attempt to perform the process with only removing the one Suzuki front bolt on the adventure rack the next time I bleed the rear brake. Haha, I have no choice really, else I will most certainly be needing to source new bolts for my top case rack and plate. I’m not even sure if I’d be able to take them off again without drilling them out. I wish they used better hardware with those kits, it’s a such a pain to source replacements.
Anyways, thanks again, you’re the best!
You are right for the bolts, i review the racks and say the same thing in one of my videos. Yes you can do it without completely removing it. Ride safe.
Άψογο βίντεο...πιο αναλυτικό δεν θα μπορούσε να είναι...Συνέχισε έτσι!!!!!Μπράβο σου!!!!!👍👍
Να σαι καλα
Very nice step by step presentation. The only unnecessary one is the removal of the side plastic panel completely. By removing the bolt, plastic clip and front portion of this panel gives you enough space to proceed. This way it saves you a lot of time and specially if you have luggage racks on your bike.
Yea, eh? I couldn’t make that happen. On my 2019 650A, those green clips at the front wanted the front panel to slide forward to unclip from the panel. It seemed like I would’ve had to brute force the panel off to get it unclipped, instead of a graceful forward slide, and I was worried about snapping them off.
Excellent video ! Easy to follow directions. Keep up the Great work. Looking forward to your next video.
Thanks a lot from France. Very nice video, very professional ! as usual ! :)
I will do it next week :)
The doctor is in the house
Nice to have this videos, thanks doctor v strom
Many thanks :)
Just one thing.
Yes, use as much brake fluid as necessary to completely flush your lines.
No, you don't have to dump the entire bottle in, because you CAN use half the bottle and then close it tightly to use at a later date.
I would not use the fluid from a previously opened container after more than a year and a half, but that is more because the stabilizers in the brake fluid break down over time than water absorption.
Once you break the seal on a new bottle, it is only absorbing the water in the air in the bottle. That is just as much as you are introducing into your brake system every time you top off/expose your reservoir to air. And you trap air in the reservoir when you seal it back up. Doesn't make sense to treat the bottle and your reservoir in different ways.
I did just toss a half a bottle cause someone else in the family did their brakes and didn't put the lid on tight. And I put the date I opened the bottle on the bottle. No date, no use.
The water absorption occurs on the surface exposed to the air. Pump, bleed, refill exposes much more of the fluid to air than the bottle.
Just a thought.

Even better, thanks
Thanks
Thanks for your video!
Thank you for the video, very good like all your videous
Adi from Romania
ADI DA thanks :)
thx for advices !!
Great video and very detailed as usual! well done and thank you. One question though - any specific instruction regarding the ABS? I believe the ABS pump is also filled with the old fluid. Do you need to somehow activate it in order to make the new fluid in or will it happen anyway when the pump is pressurized ? (Thanks from Israel :-) )
If you change regularly and before you change the brake fluid and after that, you engage the ABS in the normal way by driving and stopping suddenly couple of times on a safe empty area you will be fine. I have mine for 5 years and the previous model as well and no problems there. Just be careful on how you tight the bleeder valves in the process. If you over tight you can ruin them. Ride safe
@@DrVstrom Thank you. Will do. As a mechanical engineer I do my best to work"by the book" and use recommended torques. I wish the workshop manual was available though.... Naturally the manufacturer or dealer prefer you go to his garages.
Finally, I have an 2018 V-Strom 650 which I bought new at the time. (Still original battery😊)
Thanks. I love your videos. Great help.
Thank you for this amazing video. Can you tell me which model torque wrenchs (keys) do you use?

Thanks! Great video!
Thanks for the comment :)
It would be good idea if you could post a video how to bleed the brakes with empty system (fill up empty system). I had to rebuild my front brakes yesterday and it took me 2hours of pain to get rid of air from the system.
If you take good care of them by changing the fluid and cleaning, lubing when needed the rebuild can be avoided for long time. I did not have to do mine because of that. But I will keep that in mind for a video.
@@DrVstrom Trust me, not with amount of road salt in UK during winter. Experience first hand.
I know I was in London 2015 to 2018
Very good movie 😉
Thanks a lot for this very instructive video
Thanks Juan, appreciate it.
Muito obrigado por compartilhar informação.
Heliano Tavares Many thanks :)
Hi Doctor, today i followed your video and did the procedure. Great!
Only for the front brakes i worked 2 hours, probabily is too much.
I inserted the key and then the tube. I Opened the container and suck 2/3 of the liquid with the siringe taking care not to drop below the minimum. Filled with new liquid and started with the sequence: pump 3 times, the 4th time I keep pulled 2-3 seconds and then release (pressurize). Then i opened the valve a couple of seconds and close it again.
Repeating all the sequence. Is everything correct?
Pump the lever 4 times, on the 4th time you keep pulling the lever and then another person opens the bleeder valve, while you still keep the lever pulled. Then the valve is closed and only then you let go of the lever. This is done because if you let the lever there is air trying to come back up from the valve towards the reservoir.
Nice video for once more... I have a question, what is the diameter of the transparent hose?
Thnx.
hello, sorry dont remember this. best thing is to go to the hardware store with your vstrom. then try few tubes to find one that fits tightly.
ABS Module is an known issue on the v-strom and people say its the breakfluid degradation fault... how to flush the intire system including the fuid in the abs lines ? or this opereation also compesates the fuid in the abs lines ?
There are ways 2 ways to do so. The "hard" way that requires expensive, specialized equipment (or if you can DIY something on your own) that fires the abs unit while the motorcycle is stationary and the more easier way that does not. The "easier" way is what I follow but it takes more time however and some iterations of the following. Before you change the brake fluid go for a ride and safely engage the brakes to the point that ABS kicks in at an open road with no traffic and good friction. Then replace the brake fluid and keep some fresh spare in the bottle.Once you finish and the same day go for another ride and repeat this so as for new fluid to go through the unit. Repeat the process and you are good to go. I ve been following this method in all my Vstroms and so far my ABS units are problem free. I ve had vstrom since 2010. Hope that helps.
PSA: You can install speed bleeders AND do your brakes in half the time it takes to just do them without speed bleeders.
Πολύ αναλυτικό, επεξηγηματικό, άριστο. Σκέπτομαι να το δοκιμάσω σε ένα SV 650 ABS. Να το κάνω έτσι όπως περιγράφεις, ή να το πάω σε συνεργείο, λόγω του ABS ;
nikonian !nikonian Το βιντεο ειναι για abs, πρεπει να χεις το νου σου να μην αδειασει το δοχειο απο υγρο κ να προσεχεις να μην σφιξεις υπερβολικα τις βιδες κατα την διαδικασια.
@@IoannisParapontis Σ' ευχαριστώ πολύ. Θα το τολμήσω το συντομότερο.
If I change the rear master cylinder for a new one (bolt of and bolt on) will that cause issues with the brake fluid?
Normally you need the bleed the brakes as well and need to take care to realign properly the rear brake res tank.
How you flash oil from abs box?
Hard to do. Requires special tool to open/fire. Nevertheless if you do change regularly (1,5 years) and you do engage the abs by braking hard after the change, you ll be fine.
Hi doctor, if i would like to buy a torque wrench, may you suggest me something? I'll use it for moto, bike and everithing i need. But mostly for moto. Thanks.
Hello Stefano. A cheap, good quality solution that will cover almost all works for the vstrom is www.amazon.co.uk/BGS-Torque-Wrench-7-105-Piece/dp/B001ILCRKQ/ref=sr_1_5?keywords=bgs+torque+wrench&qid=1585311426&sr=8-5
@@DrVstrom Maybe in your videos i saw that you use also a smaller torque wrench or is wrong?
Thanks.
Stefano Lubiato yes but this one is more expensive and does not cover all parts like the bags does. I also have and use the Bgs
Μπορείτε να μου πείτε τι διάσταση έχουν τα σωληνάκια και σε τι κατάστημα μπορώ να τα προμηθευτώ;
ditodeejay το καλύτερο είναι να πας σε ένα κατάστημα που πουλάει σιδερικά κ χρώματα, βίδες κτλ. Λες ότι θελεις τον διάφανο σωλήνα από σιλικόνη που χρησιμοποιούν κ οι οικοδόμοι η αλλιώς αλφαδολαστιχο. Για το μέγεθος πάρε μαζί σου μπαίνοντας στο κατάστημα το λαστιχένιο καπάκι της βαλβίδας που βγαίνει τραβώντας το κ δες για τέτοια διάμετρο. Εγώ είπα να μου κόψουν δείγμα από τα 2 πιο μικρά σωληνάκια που είχε κ επί τόπου πήγα στην μηχανη να δω ποιο εφαρμόζει καλύτερα. Μετά πήρα εκείνο.
@@DrVstrom Ευχαριστώ πολύ!!!
Αν το κάνω μόνος πως θα κρατώ το φρένο κ θα ξεβιδωνω?
Hi, how much oil do i need for front and rear brakes? Thanks.
Stefano, you can get one 500ml bottle and use 350 for the front left and right calipers and 150 for the rear. You cannot save the brake fluid so you will need to use all and better do all brakes within few days cause once opened, the fluid absorbs humidity.
@@DrVstromThanks again doctor!But...do you have the service manual? Because i see that you know all the tightening torque..
Stefano Lubiato some Vstrom forums might have it. For my videos, since I give the torque values you can do without it.
Καλησπέρα.
Αφαίρεσα τις εμπρόσθιες δαγκάνες για επισκευή και δεν μπορώ να τις εξαερώσω με τίποτα!
Πρέπει να συνηχήσω την ίδια διαδικασία μέχρι να εξαερωθούν ή υπάρχει κανένα κόλπο;
ditodeejay Ναι είναι πιο χρονοβόρα τώρα η διαδικασία. Κόλπα υπάρχουν. Ένα είναι στο τέλος του βίντεο. Θα πιάσεις με δεματικο την Μανέτα όχι πολυ. Αυτό θα δημιουργήσει πίεση και θα μετακινήσει τις φυσαλίδες στο πάνω δοχείο. Άλλο είναι να χρησιμοποιήσεις τρόμπα κενού αέρος που ρουφα το υγρό από την δαγκάνα και εσυ απλά γεμίζεις το δοχείο. Αν δεν θες να αγοράσεις τότε θα σου πάρει λίγο χρόνο. Πάρε 2 μπουκαλάκια και αρχικά πέρασε το ένα. Πιάσε την δαγκάνα με το δεματικο για 8 ωρες. Ξανά εξαέρωσε με το άλλο μπουκάλι και βλεπεις. Μην ξεχνάς στο άνοιξε κλείσε της βαλβίδας όχι πολυ δύναμη γιατί τα πάσα είναι ευαίσθητα και μετά θα έχεις άλλο θέμα.

Καλησπέρα και ευχαριστώ πολύ για την άμεση απάντηση.
Δεν νομίζω πως το δέσιμο θα βοηθήσει καθώς η μανέτα είναι πούπουλο και όσες φορές και αν τη πατήσω πάντα φτάνει μέχρι τέρμα.
Θα δω μήπως με σύριγγα κάνω "ανάποδη εξαέρωση" από τις δαγκάνες αλλιώς πάω για τρόμπα κενού μετά.
ditodeejay Μα πρώτα σου είπα να περάσεις ένα μπουκάλι κ μετά να δέσεις. Θελεις παραπάνω χρόνο αφού μπήκε αέρας στο σύστημα. Θα δεις ότι σταδιακά θα έρθει.
