BMW ISTA DSC Brake Bleeding Routine (F2x/F3x/F8x)

Рет қаралды 25,024

Күн бұрын

Here's a peek at how to find and go through the DSC brake bleeding routine in BMW's ISTA program. I don't cover getting the fluid out of each corner in this video, but you can see that in this other video of mine ( • BMW Brake Fluid Bleedi... ). The DSC activation routine isn't really needed unless you get air in the lines, which can happen from a mistake during bleeding, after swapping brake lines, or brake calipers.

Hi Farkle. I've said this in your other videos a while back but wanted to say thanks again for all your helpful videos. You literally always come to the rescue when I mess things up. I also introduced air into my lines while doing the brake flush and was shitting my pants, but sooo glad you made a video on exactly the problem I was having. The Bimmer community is so lucky to have you. Thanks again man!!!

@FaRKle0079 6 ай бұрын

Glad to help! When you're bleeding your brakes to get the air out I recommend stepping on the brake pedal rapidly and very hard to try and dislodge any bubbles while doing the ista bleed. That'll give the best chance of getting rid of the air.

This ISTA bleed for the DSC fixed the problem.

Yes, I have a scan tool that allowed me to bleed the ABS but the ABS was not my issue at all it was a Master that would not release all the way.

Hi there, short question, when u press the brake pedal with the open bleeder valve, should it go all the way down both axles? I have an issue on my car (e64) the pedal goes all the way down and pushes fluid with pressure on front axle but on the rear it doesn't go all the way down and also no pressure at the bleeder valve.......is this normal?

So in "Rear axle DSC bleed" step (from 4:50) I need to open bleder screw and just left it open for the whole bleeding time? When doing manual bleed you open bleeder screw for a few seconds at a time, right? But here seems like I just need to open it, leave it open, then press brake pedal then hit continue and then wait for the whole ~30 seconds procedure to finish and only then close the bleeder valve??

This morning I was driving on the highway and the car in front of me slammed on the brakes with cause my front collision system to engage and after that when I’m driving about 0-60km/h I heard a scraping noise I bend the dust shield back but no stone fell out also my brake fell good at high speed braking but about slowing down from any speed I heard a loud scraping noise and coming to a stop it fell as though the brake engages backs off abit and then engages and back off abit and engages again and repeat until it comes to a stop all of this happens really fast but I can feel it

I don't have access to a power bleeder where I'm from. Would it work the same if I just make sure the brake fluid level doesn't go super low? I was thinking of getting a bleeder bottle and letting the brake fluid from the caliper nipple flow there. Did you hold down the brake pedal after ISTA said that the bleeding is complete and get your buddy to close the bleed nipple? Or was it just let the fluid flow out and see if there is air in the lines?

@FaRKle0079 Жыл бұрын

You need a pressure bleeder for this routine to work. It'll be incredibly difficult with a "2 person method" of opening the nipple, pressing the pedal, closing the nipple, and then releasing the pedal while the system is pulsing. With a pressure bleeder you can just press and release the pedal since the system is always pressurized to push fluid out of the nipple.

@darylmorse 2 ай бұрын

Great video! How much fluid did you use going through this procedure? According to ISTA+, you are supposed to bleed all four corners again using the bleeder. If you bleed all four corners, then bleed the DSC, then bleed all four corners again, that sounds like 2-3 L of fluid.

@FaRKle0079 2 ай бұрын

If you do a flush beforehand, and then the DSC bleed you'll use 1.5-2L of fluid. There's no real need to bleed all four corners again after completing the DSC bleed.

Another fantastic video. 2 quick question, if you don't mind. I'm doing a CCB retrofit onto my '18 M2 (requires a different booster, which requires the master cylinder to come out) and I've read of several guys doing the job without needing to do this procedure (they had firm pedals after a few traditional bleeds). They said that they did the traditional bleed, then did a few hard stops to invoke the ABS, then did another traditional bleed and they have a firm pedal. 1. Even with a firm pedal it's possible that there is still air in the DSC/ABS module, correct? 2. Is there danger in leaving that air there if I have a firm pedal after the above mentioned procedure?

@FaRKle0079 Жыл бұрын

I believe you can have air (or old fluid) in the DSC module but still have a firm pedal if you're not activating DSC. If there's air in the DSC module, it means when ABS is supposed to activate, it probably won't be pulsing braking on/off as much as it intends to. For normal everyday driving where you're not getting into ABS it's probably a low risk.

@andrewthompson6893 Жыл бұрын

This procedure is only really needed if you get a decent amount of air into the brake system. I don't do this unless I really need to. If you're getting too much braking power early on that's really weird. When the car is on the brake booster should be active. I wonder if the pedal feels boosted/overly strong with the car off too.

Hello, maybe can you help me. I changing brake fluid on my bmw e61. When i activating the abs pump to release air bubbles, its works, but on my dash for a few seconds come out "abs dcs" error. When i repeating the procedure, it happening again and again. Now, after fluid change, the brake pedal feels need more power to stop to full. There is no air bubbles, no errors about abs. What is the problem? Now, when im writing this, i remember when i were bleeding the brakes, i forgot to add brake fluid to the reservoir and some air maybe got in the brakes and that "abs dcs" error come. How to fix this? Thank you!!!

@FaRKle0079 Жыл бұрын

If the brake fluid reservoir went dry, you likely pushed air into the brake system, which would definitely reduce your braking power and solid pedal feel. You'll need to bleed again (possibly multiple cycles) to clear that air. I also recommend stepping on the brake pedal very quickly and with a lot of force during pressure bleeding to try and get that air in the system out.

I changed my fluid for the first time and might have let the pressure bleeder run too low and let air into the system but I'm not sure.

You're correct on the rule of thumb, however that doesn't really apply when you're pressure bleeding. Since the reservoir/brake system is always pressurized, it's always trying to force fluid out, even when lifting up on the brake pedal.
