How to CHANGE BRAKE FLUID on a BMW M4/M3 (F80/F82/F83) with StopTech calipers

If you want to buy an "I AM THE WARRANTY" shirt OR if this saved you a good deal of time and/or money and want to buy me a coffee or a beer, you can do those things right here: ko-fi.com/help...
Went to Rennpart to have Aaron change my brake fluid for me after my most recent track weekend. He shared his preferred method with me, which I am now sharing with you! I'll link to some of the tools he used below.

I do this however I dont put any brake fluid in the motive bleeder. I just use the motive to pressurize the brake fluid reservoir. Then I refill between each corner. That means I never have brake fluid in the power bleeder. Just a cleaner way to do it, of course being mindful of not pumping air by letting the brake fluid get too low in the reservoir.

[@HelpMeDIY]

+Johnny Johnson I guess you save time cleaning and spend more time filling the reservoirs and re-pressurizing. Both ways work :)

[@mastershredder2002]

The motive instructions that come with the bleeder specifically says "DO NOT WASH WITH BRAKE PARTS CLEANER", yet this guy suggests doing it at 25:14. Now this guy has brake cleaner in his brake lines. Great. It's one of the only two bold parts in the instructions that come with the bleeder.

[@HelpMeDIY]

+MasterShredder he did accidentally say that, good catch. I always clean mine with denatured alcohol as recommended.

Excellent video mate. I am not a mechanic but just wanted to see how the job is done and to be honest everything the person done on this made proper sense nothing out of ordinary. Thanks again for the video.

Thanks for sharing. Just a couple of things for me, when bleeding a caliper which has two nipples like that, the outside should be bled first. I would sit the pressure bleeder in the engine bay for a couple for reasons, but mainly to keep anything from rubbing the paint work there.

[@HelpMeDIY]

+@allymacmillan7986 you’re welcome 😎🍻

[@cassoidGaming]

You are correct. The bleeder should be bled outside first. But some BMW repair instructions very on car to car and some say bleed inside first then outside. Some say bleed outside first then inside. Depends on Make and model of bmw. But good catch

Hi, so I have an air bubble, from the motive to the reservoir, there isn’t a solid stream line. Also, when it’s flushing out into the catch bottle, it isn’t coming out in a solid stream either. There’s a lot of air as well as bubbly liquid. Is this normal or is there air getting into the lines?

[@HelpMeDIY]

+Andrew Chow there may have already been air in your lines before you started, but it should not be introducing new air into your lines. You should see that there is already a lot of fluid in the reservoir, and fluid is being sucked in from the bottom of that so as long as there is fluid in it, air cannot be getting in.

Nice video. And i've learned something i think the good way of brake bleed. Thanks

Thanks for the helpful video! I hope your assistant did not jack up your car without a jack pad!

[@HelpMeDIY]

+Kevin Ryan you’re welcome! No damage was done 😁

[@BastidasBryan]

Is it normal to see air in the motive line to the reservoir? Does air get into the brake system that way? Also what if I do get a lot of air in one of the lines

[@HelpMeDIY]

+Bryan B yes it’s normal and no, it won’t get into your system 😁

[@Juspunjabi11]

Awesome video but quick question? Because you have the upgraded stop tech brakes & calipers, I don’t have to follow the rear brake procedure since my rears are the stock M brakes? You bled from both points in the rear instead one in the back. I’m assuming this is because I have 2 piston brakes in the rear and 4 piston in the front. So the 4 piston brakes would need the double bleed instead of the single like the 2 piston correct?

[@HelpMeDIY]

+Juspunjabi11 thanks! Yes, that sounds correct. If there’s only one bleed valve that’s all you have to do :)

[@Juspunjabi11]

@@HelpMeDIY awesome thank you once again! Your videos are life saving and save me so much money! Honestly thanks again!

[@HelpMeDIY]

@@Juspunjabi11 that’s great! Love to hear it. Ever consider becoming a channel member? 😉

[@otebol]

That's funny that the plastic piece covering the fluid reservoir is bolted down on the F82.. On the M2 its a single clip on the side and just rests across the windshield side lol

[@HelpMeDIY]

+otebol Maybe it doesn’t need to be bolted down because it’s slower? Haha I kid!

[@ecliffg]

What are the torque specs for tightening the bleeder valves?

[@HelpMeDIY]

+ecliffg “until fluid stops coming out” 😆 I’m sure there IS a torque spec, but everyone uses these wrenches and I’ve never ever seen anyone use a torque wrench for it. Just go nice and snug, don’t break them off and you should be fine.

[@ecliffg]

@@HelpMeDIY that's what I'm going by too, BUT i started seeing some fluid creeping out. I'm not sure if its because I didn't tighten it enough or if there was fluid trapped in the bleeder valve itself after I had stopped and its just coming out now... i'm hoping for the latter but don't want to over tighten the bleeder valve and mess up a caliper. Any advice?

[@HelpMeDIY]

@@ecliffg tighten it to where it feels pretty tight but you don’t feel like it’s too tight is the best I can do. Then dry it off and keep an eye on it. If there is brake fluid after that the I’d get a new valve

[@ecliffg]

@@HelpMeDIY Thanks. I doubt it would be an issue with the bleeder valve since the vehicle only has 16.5K miles. I checked the valves and they feel snug and not too tight. Will try with a syringe and see if there are fluids trapped and siphon it out... Thanks for the timely response
