A KTM 390 Adventure. Two year maintenance brakes pads/bleed.

- In this video I cover changing the brake pads and bleeding the brakes on my KTM 390 Adventure. I have 22,500 miles on this bike and the back brake pads were looking pretty worn, so it was time for replacements. Since I was changing the rear pads I decided to change the front pads at the same time. The process is pretty easy but I learned a few new tricks you might find helpful if you want to do this yourself.
i look forward to referencing this when i get to this point, as always thank you for your guides and keeping them going!
Look through the comments. There are some useful tips. Thanks.
It’s a good practice to get your drain tube system hooked up to the bleeder valve and then open the bleeder valve BEFORE pushing the caliper piston back in. This way, you’re forcing the old brake fluid out of the system, not back into the system. (It’s also easier, because you’re not pressurizing the brake fluid reservoir by forcing fluid back up that way, too.)
Also, a small syringe is a handy tool for filling the brake fluid reservoir. Can be found at marine shops where they sell epoxy, maybe at hardware stores. Brake fluid removes paint, so you don’t wan to dribble it if you can help it.
Good tips thanks.
I always clean my pistons before pushing them in. I do this because once, when just pushing them back in, I forced road grit into the seal of one of the caliper pistons. I ended up having to get a rebuild kit to stop it from leaking fluid afterwards. - Frank
Good idea.

I bleed on my bike all the time.
Thanks Matt,
this is going into my "how to" file,
that I put ...
somewhere.

Thank you for this info.👍
Thank you Matt for taking the time to make these videos. Really helping on my additions. Any suggestions on short clutch, brake levers. Lots of options out there. Thanks
I haven't found any levers I like. I cut down my clutch lever and I am using a cheap brake lever. Not a matching pair. I need to fix this. Send me suggestions you have on brake levers.
The more important reason for changing the brake fluid is retained/absorbed water, not so much being dirty. Water causes your fluid to be spongy and also rusts the brake components.
Absolutely right. I should have mentioned the water absorption.
Great content ! Also for a beginner like me !
How reliable is the KTM Adventure 390 ? Are you satisfied with this bike ?
I’m really interested in it in addition to my First bike (Yamaha XSR125) and doing more longer travels trough Europe next Year with a bit of Off road (not the hard one partly on the TET trough Europe).
Thanks for you answer and Your great work !
Thanks for the feedback. I love this bike and as of right now there is not another bike out there I would replace I with. The biggest issue I had was blowing out the rear shock, but I pushed this bike to its limits. I did a video on the reliability that you might find helpful. ua-cam.com/video/ZvlOYKMtlaE/v-deo.html
Get some speed bleeders. Makes flushing ALL the fluid very easy. Maybe the ABS system functions differently on newer bikes, but on my 2015, I've never experienced the problem that you did while bleeding brakes. Over 60,000 miles, I bled my brakes 12+ times due to annual maintenance and also tried a couple radial master cylinders before setting on the best one.
Yeah, I thought of that, but forgot until I was ready to do the job. Thanks for the reminder.
Do you know what size speed bleeders are needed?
@@davidevans7350 Sold the bike and deleted the file with receipts. Look up the OEM bleeder valve online since KTM lists the sizes of all their bolts & bleeders.
I don't know this bike or any bike actually, but as far as hydraulic brakes go, I see a couple issues. First off, it looks like your pads were not worn evenly. Whatever bolts they ride on either have worn someway, lack lubricant, or dirty. As I don't know this particular brake caliper, I can't say more than be sure to investigate how the caliper slides and maybe even seals that keep dirt out, and the proper lube. On cars, the sliding part of the bolt uses specific grease just for that job.
Second, even if your brake fluid looks good, it's always best to flush it completely. Get a clear jar you can see. Fill reservoir, crack bleeder, squeeze out all the old by repeating this and your sure all the old is out. While doing this, actually get two jars, one for flushing, one for bleeding. The purpose of the hose and jar isn't simply to catch the old fluid. When you bleed, be sure the jar is super clean, and so is the hose. You shouldn't have to worry about the angle of the hose because you squeeze and release till all the air in the tube is out, then shut your bleeder. You may need help with someone monitoring the reservoir and keeping it full as you're doing all this.
This is how you are sure to get all the air and dirty fluid out of the brakes and have the best brakes possible.
I just watched the part where you remove the pin which I was calling a bolt. They are definitely dirty and should be replaced and the hole they ride in honed clean.
Thanks for tips.
I was going to bleed the back brake on my Duke because it was feeling spongy, but I was told it had to be done at the dealer because of the ABS pump so I brought it in. So all you did was have the key turned on, or the engine on to have the ABS pump work?
Yep, the rear brake I bleed with the engine off, no issues. But as I described, I ran the bike to bleed the front. The only thing I noticed was the break in on the front pads was longer than expected. It had very little bite for the first 400 or so miles but once fully broke in they grabbed hard.
Hi matt. Izham here from malaysia 👋
I do own ktm adv 390. Does rear brake doesn’t grip well?
Try changing brake pads to sintered. I think the stock pad is organic. Also, bleed the brakes.
hey looks like the spring retainer on front brakes got installed upside down 4:45 vs 5:55
Actually, looking at the video, it's not upside down, it too low, it should have been sitting higher in the caliper. I didn't even notice when I did the install. I need to go back and check it. Nice catch, thanks.
My breaks on my 390 squeaks , how are the new ones ,did yours squeak also?
No squeaking. They had a short break in period then bedded in nicely. The rear brake feels much better than it did before.
