G20 02NH MSports Brake - Coding Required?
Hi, hope I posted in the right topic Does anyone know if I retrofit my G20 320i with the M Sports brake kit 02NH (removed from a 330i), would I need to perform DSC coding? I'm asking because it seems that many experienced mushy brakes when they installed the M Performance brakes until they get the coding sorted, and I'm wondering if M Sports would be the same.
Thanks! |

Please check to make sure the DSC and master cylinder are the same for both models. A quick search on Bimmercat.com would suggest the DSC is the same but the master cylinder is different. Larry

And thanks for pointing me to Bimmercat, seems that M Sports and M performance users the same master cylinder (34336892205), and I do need a new master cylinder. That's interesting because I noticed the M Performance Brake Kit sold doesn't come with the master cylinder simply because 330i and above uses 34336892205, while I'm on 34336892204. And theres no 320i in North America. |

M-Performance Brake Kit Installation instructions lists a version of the kit that includes a brake booster (https://rparts-sites.s3.amazonaws.co...ll%20Instr.pdf) I checked Bimmercat and it looks like you may also need a booster for the upgrade. Larry

Finally got it installed - the shop couldn't get the brake booster / master cylinder on, so that is still something to do. Initial response: brakes feels much softer than stock, the mechanics were so worried they re-bleed twice and wasnt comfortable with me driving away. I find it drivable, but wasn't very confident with ebrake.
Got it coded today and to be honest, couldn't feel a big difference with before i code. So until I get the master cylinder changed, won't be able to tell much. |

Looks great! Sorry to hear that our fears about mushiness on the brake feel came true though. Was this the first retrofit that the workshop did? Kinda troubling that the mechanics themselves were surprised...
The clearances on 19 inch rims look really tight on the front. Pretty sure there are some designs which would not fit. |

My previous car was a 4 rings so the workshop specializes in that This was the first fit up of mperformance brakes on a G20 there. Swapping of master cylinder.. probably not that common haha. |

I have the same pedal feel after I installed the M Performance kit on my 330i. Initially the pedal was much softer and really have to press down far to get any stopping power. Although after driving 1000 mi and the pads starting to bed in, I did feel some improvement though not as much as I had hoped. Lurking around in other forums, people have said that it's the M Performance pads that don't have a strong bite. I wonder if swapping the pads will help.

I have a set of BBS XR 18" ET28 for my winter setup... No clue if they'd fit over the M-Performance setup. |

Will 790M wheels clear the front caliper?

Despite what the shop told you, the official instructions calls for a retrofit a new brake booster..
Nice mod regardless https://rparts-sites.s3.amazonaws.co...ll%20Instr.pdf |

yup currently in same situation as the OP
bought the kit without the booster and brake travel is to the floor although everything else was done perfectly bought booster/cylinder setup with part# 34336892205 which is what is listed on realoem as the booster for the Msport/M performance Red setup what is confusing though is when you search the brake kit that comes with the booster on bimmercat the booster with the kit has part# 34336892203 reached out to a lot of persons in different countries and 2203 is either discontinued or they have no idea what it is for hoping the part from realoem solves my issue, would be nice if OP could respond and let us know if he ever got through |

Hey guys sorry hasn't been on the forum for a while missed this. I had the brake booster but never got it installed. I got it coded for mperformance brakes, and after bedding in plus 3000km later, it felt better, but I still didnt think its great. I had 4 pots brakes in my past two cars and the experience was always good progressive modulation feel when you depressed the pedals, but it feels I need to press harder and more here. Good news is I had to eBrake a few times and I always got it to work I would install the brake booster eventually
