Brake bleeding HELP !!

rustyminded · 04-21-2016, 03:58 PM

Hey friends, I just thought to give the caliper a new look dark red so I went to this shop who is professional in their work but here i am ending up in a dilemma with brakes the thing I feared.. after bleeding brakes since they removed whole caliper for painting and i thought to put new brake oil when I started to move the car, it literally had no brakes !!!! the guy bled it over 5 times and we end up the same so we checked the cap and there was a little sound seemed like it needed to be changed but he told me that it needs coding even if this cap was fixed.. so I need to know because it's a hassle to do that coding I have to put the car on a lift to be moved.. what coding I already have E-sys and ista.. please I need help to know what's wrong maybe they did bigger damaged

Need need ISTA/D Rheingold to actuate the DSC/ABS system for a complete system bleed.

There are two variants of ISTA.

ISTA/D Rheingold - for diagnostics/factory service manual
ISTA/P - for programming similar to E-Sys but more fully featured. this should allow you to do flash programming on firmware.

I have the Rheingold one. what's the next step

I haven't done it yet but this is my guess...

Service Function -> Chassis and Suspension -> Traction Control System -> Brake bleeding routine -> ABL Brake bleed routine

You didn't bleed it right.

I've bled brakes on my own, and never had to reset or do anything.

You can do it this way as well. That's how I've done it in the past.

From what I gather from the Bentley service manual and ISTA/D Rheingold is that if you're not opening up the system (ie. replacing lines, calipers, etc.), you can do the traditional brake bleeding method.

Once you open up the system from a location other than the brake fluid reservoir or the bleeder screws, it is recommended to use the ISTA/D Rheingold to activate the DSC module as part of the brake bleeding process.

Ok thanks for clarification b

Exactly right - well said. I think there are two issues at play in many of these mushy pedal threads related to brake upgrades, etc. The lousy M Performance brake pads, and/or poorly bled brakes. Using a power bleeder for normal caliper/brake line replacement should yield excellent results.

Yeah I should've mentioned that, power bleeder is the only way!

Make sure you don't let them runaway. That's probably gonna be a big bill.

Need some help, I’ve replaced the front calipers of the vehicle and then performed the bleeding procedure after, started trom the rear and moved towards the front, so I’m having issues with no getting any fluid from the right front but u have fluid coming out from the driver side LF. I’ve replaced the brake hoses and still got no fluid coming out from one side. Any suggestions or has someone had the same issues before with their f30 ,320i I’ve always attempted to pressure bleed but still wouldn’t get fluid coming out from that one side. Any tips or recommendations would be appreciated.

This is when you need ISTA for its bleeding procedure. ISTA will resolve that issue.

There's a failsafe valve feature on the DSC/ABS module that prevents the braking system from completely bleeding itself out in the event there's a leak in parts of the brake fluid circuit.

I've seen this at BMW CCA DIYs when someone mistakenly runs the brake reservoir dry on a regular air bleed routine.

Disconnect the hose from the caliper that's not bleeding, make sure fluid is coming out of it. If it's not you've got a blockage somewhere. If it is reattach it, then see if the caliper bleeds. If not there's a blockage in the caliper.

It's very likely the "blockage" is in the DSC/ABS module.

Billfitz · 12-31-2023, 08:06 AM

There's one way to be sure. If there's no fluid coming out of the brake line disconnect it at the RP hydraulic unit DSC and see if fluid is coming out there.

If someone doesn't have access to ISTA or a scan tool with a similar feature, sure.

But that's a lot of work compared to just running the ABL Brake Bleed routine in ISTA. You may not have to disconnect anything.

Billfitz · 12-31-2023, 04:25 PM

I'd venture most of us don't have ISTA. I don't, and I've never come across anything that I couldn't handle without it. Of course having said that I'll probably need it next week.

I just checked, my Foxwell NT510 does brake bleed, so I'm good there anyway.
