this entire video is actually the most important part that every other video forgets to mention about bleeding brakes

You’re a life saver. I’ve done a lot of bleeding, not so much priming. I guess I’ve always just been a bit lucky up until this new build. You’re the man 🤘🏻🤘🏻🤘🏻

I just hate to admit it... but yes ,,even as I am over 60 and been riding since I was 13 years old ,I have been that man bleeding brakes all day ,,lol now I know ,,thanks a mill Delboy,,never to late to learn.

Can I just add my little extra tip. Don't rush. I mean, after you've bled, and are sure there are no micro-bubbles, go out on the bike if you have to, but take it steady. Then 24 hours or more later (if you have a remote reservoir) remove the reservoir cap, carefully squeeze the rubber connecting tube, or agitate the lever careful not to spill any fluid if it's an integral reservoir, and I can almost guarantee you will see a nice little bubble rise from the hole at the bottom. Let physics bring any remaining air to the highest point of the system (master cylinder). I changed my GSX-R 750K2 front brake master cylinder on Tuesday, it had a firm lever, and on Wednesday ran some more fluid through to be sure the calipers were bled after settling, then today (Friday morning), I popped the reservoir top off, and squeezed the pipe, and there it was, the final bubble.

I just bought the biggest syringe I could find, a piece of 6mm fuel hose and just applied vacuum to the last bleed valve on the system :) worked like a charm, just remember to top off the fluid to not to suck air from the other side ;)

What a useful guide, thank you. Just about to fit new stainless lines, after a calliper rebuild on my old Kawasaki Gt 550. This video has probably saved me a lot of head scratching during the bleed process. 👍

Most welcome buddy. Glad it helped.

Doing a complete rebuild of the calipers with new lines; this information saves me time and frustration. Thank you.

Good tips I worked for many years in a pneudraulic workshop on military aircraft components. Some of the first rules I was taught are that air always wants to up the way…sometimes tapping with a soft faced hammer can help dislodge air bubbles and sometimes you need to take the component off so you can prime it properly by hand. Messy business but works. Failing all that plumb it into a system than delivers flow of 100ltrs per minute at 4000 psi…that’ll sort out any air bubbles 😛 However I do like a syringe from the bottom on my bikes as air likes to go up the way 👍 Got a subscriber now

I'm a frequent watcher of your videos and love the work you do. I was recently replacing brake fluid and accidentally left the bleeder screw open and sucked air into the master cylinder. As hard as I tried, I couldn't get any pressure at the lever; I watched this video, disconnected the line and let it gravity bleed. I had to re-bleed the caliper, but with line pressure it was done in short order. Thank you for all the information and entertainment you provide.

And thanks for the help with my pirated Yamaha caliper on my cycle kart.

Man u hv so much patience.I gave my mechanic a brand new master cylinder with the brake hose, the guy opened the master cylinder and damaged one rubber ring then he removed the old one from the old assembly and put it on the new piston in the master cylinder still not working properly even when the lever reaches the end the wheel barely stops.

I just used your video to prime my new brake system on a restoration project! Worked perfectly well!!! Thank you so much.

Awesome video. As usual, you passed on another trick of the trade! I am about to rebuild both front and rear calipers on my "new" k2 gsx14 I got from my cousin! Rear brake isn't too bad, but the front end is a mess. Brakes are grabbing too much, so dangerous. I have cleaned them, but I suspect it is even worst. I did not make a perfect job of cleaning them, they were so dirty. 4 hours scrubing that black stuff, not all of it came out. with new pads pistons went in. Even if 5 piston work great and one is block, that is enough. And that is waht happened to me, so I decided to make a rebuilt. Thanks for sharing Del

Thanks for making this video, mate. It really helped me. I thought I'd let you and others know that it took about an hour of tiny brake lever action until no more bubbles were showing up. Then I just when to the callipers and started bleeding them, and presto I have working brakes!

Proper old school mechanic, I use dot 5.1 fluid as I live in very hilly part of the country, lots of long downhill braking works for me,

Delboy, You certainly showed this old "motorcycling brother" what a Plonker, brothers can be! I am a Brit, who's been living in the USA for 30+ years and my common sense got diluted by pure time and geography. You straightened me out. I've been hours trying to bleed the front disc after fitting a speed bleeder and a new caliper on my old Harley. I'd forgotten that gravity is not just a cool idea, but simply the 'kin law! Thankyou Sir. It took less than 2 minutes; remove the banjo joint, draining the pipe, refit it and pumping the new stopping juice through the Speed Bleeder! Speed Bleeder: 3/8" x 24 thread. Goodrich or Russell on Amazon. $15-ish a pair. I had a cold one in your honor Del! Thanyou.

I got some extra length on my hoses as I want to put riser's on soon ,but I was convinced the extra length had made it impossible to bleed. I even tuck off the calipers and let them hang so the hoses where in a straight line . Anyway I finally got them . Cheers pal . I was thinking of putting braided hoses on my gsxs 1000 but after what iv been reading here on ABS systems I might give it a miss 😁 . Great stuff

Dry or not, occasionally I use a vacuum tool ( Mity Vac for example ) from the top. I made a small aluminum plate to cover the master cylinder which has a bleed nipple on top, two mounting screw holes in my case, and rubber gasket on the bottom. Put the plate over the master cylinder, screw it down if you can, attached the vacuum hose, and pump several times on the vacuum pump. At the same time, active the brake lever several times. My brake levers are well and truly hard as a rock if done right.

Nice vid of tips for the DIYr. May have to make use of the tips when I decide to upgrade to braided lines.

Second time I’ve watched this one. Ironically my KZread home page algorithm seems to know when I’m about to do a job in the garage now. Rebuilt calipers last night (pistons aren’t necessarily perfect but nothing was leaking before) and new braided hoses arriving today. Master cylinder rebuild this weekend also. Wouldn’t have ever attempted this build without your help Del.

Mate can I firstly say this vid saved my insanity trying to prime a bone-dry system. I have a 1995 VN800 turned into a bobber and in the final stages of the recent rebuild which included new bars and controls all in black. The last job which was frustrating me was the front brake, it had only a new MC and braded hose but certainly the system was empty and your vid was exceptional in its delivery and explanation so bravo. As a tip from me using your method to quicken the process for an empty hose fill it using a large plastic syringe (minus the needle which you can get from a chemist/pharmacist) this removed most of the air and was easily done. Made the job a bit quicker. Again many thanks for this vid would be at the local mechanics shop by now.

Brilliant !, Just put new hoses on, wish i saw this before i pit them on !.

I had high spots in the middle so it didn't work, I ended up using a hose attached to the bleeder and to a bottle then bottle to vacuum cleaner haha. Worked in seconds, I was committed to getting it done without spending any money haha

Oh dude. Thankyou so much for this video. I changed my handlebars so I needed to change my front brake line for a longer one. So I thought you bleed like normal, and I pumped amd pumped, bled and bled but could not get any pressure in the line. I tried for days and days and even bought a new brake cylinder and still the same thing. So I gave up and said oh well I’ve got my back brakes. Then I thought I’ll see if anything on KZread and chose your because I seemed straight forward. And what do you know it worked after 20 min. Then bled the nipples with 2 bleeds and my grip is so firm now. Thanks buddy cheers

Ive ALWAYS primed everything i can be it a car or a bike, ive actually just rebuilt, today the 6 pot tokico's from my TL1000r, i use a syringe to fill both calipers thru' the banjo bolt hole, finger over hole, move it about so it gets into the space, then top up, have banjos n bolts ready, pour fluid into res', wait until it starts to piss out, fit bolts n tighten pull lever in+out...let go, loadsa bubbles, few more times, job done....but...if EVER stuck...try using a large syringe and start from bleed nipple and fill it 'backwards'...they can be a bastard to bleed if your inexperienced....this is also a good tip delboy 👍

Good advice indeed mate, i use a syringe a lot these days, often to backfill all the way to the top, then a quick bleed down to firm up the lever.. You need a decent quality heavy duty syringe to apply enough force, so the usual "chemist shop off the shelf item won't do... i use one of these, works really well, :- www.spanner-monkey.co.uk/oil-and-brake-fluid-inspection-syringe-200ml-120826?search=VS404&description=true

i had a problem with brake fluid won't bleed... i pushed the leaver for an hour almost... but i found easy solution : just blow in to the pipe (bottom end) so all air bubbles out from top... after that just few minutes and all good... just be careful not to taste brake fluid 😋
