Hey guys, I just had a pop question since I just coded M perf. brakes on my base 330mm brakes with single piston just to get better brake feel but I want to know what are downsides of it, is it dangerous like ABS won't work ?! will ruin rotors ?!
I can confirm it's making big difference on how car brakes not just feel

p.s I have base brakes but upgraded lines, semi-metallic pads and slotted rotors (same stock size)
330/24 mm front
300/20 mm rear

C_Variante_Bremsscheibe_vorne_e change to--> 370mm
C_Variante_Bremsscheibe_hinten_e change to --> 345mm

I dont see how coding m perf brakes does anything in terms of brake feel.

The brakes are purely hardware controlled (pedal moves piston in brake cylinder which pushes fluid to the brake pads). theres no software that controls that. - but i could be wrong.

The m perf brakes coding i would assume only effects the ABS and traction control.

it's odd to me too but couple of my friends drove car and confirmed without evening telling them i did anything to the car.. anyone installed M perf brakes say it needs coding because feel is mushy. check down lost you'll find one posting about it

I found a reference somewhere that the sport brake coding changes the proportioning valve values which might be changing the percentage of force at one end versus the other.
Have you attempted to brake hard enough to trigger your abs ?
If the brake bias has been changed by your recode you might get some unexpected lockup prior to abs cutting in.
I have installed the complete 335i brakes on my 2014 320ix and have not changed any coding. I have 340/30 with 4 piston and 330/20 with single piston calipers now up from 312/300
I was going to look for the coding place to change rotor sizes but haven,t done it yet.
I,m not overly concerned because the ratio of rotor diameters has stayed similar to before.
I just purchased a cable but don,t know how to code or where to look

No didn't attempt to trigger abs. I'll try different sizes though maybe I'll stick to the ones same thickness as my rotors.

check this out diy for coding

the reference to what changes is by "Pikcachu" in a thread called "MPBBK-coding required post DIY install?" 08-19-2014 in the 2 series forum I don,t know how to link to it

Hello

I coded it myself sport brakes on my BMW F30 using the following procedure:


http://f30.bimmerpost.com/forums/sho...d.php?t=929406





=> Connect
=> Expert Mode
=> Coding
=> Read FA
=> Save FA
=> Editiors and viewers
=> FA-editor
=> Go to HO-Wort and right click on "Edit," then type "SPBR" under the HO-Wort file
=> Select the FA, right click "Enable FA" and "Calculate FA" to verify that no errors are found after adding the SPBR.
=> Check the vehicle profile to locate the "" aftermarket retrofit "and check" SPBR_18_ZOLL_SPORTBRAKE "has been added to the file
=> Write (write) FA to your car. No confirmation window will appear after saving the FA to the car
=> Expert Mode
=> Coding
=> Read (read) the FA. You are able to see SPBR be added to the HO-Wort folder on your car.
=> Read SVT, and locate the "DSC" (File Folder SVT / ECU / DSC), then right-click the "DSC" folder and select "Code". Consolidation should start immediately.
=> Allow the coding is over, and repeat step 1 to save a copy of the new FA.
=> Disconnect the car's computer. The M-Performance brake is now activated and enjoy the authentic experience of M Performance brake.

it will also manually changed disk size in the DSC file

[johnsjmc]

What would you code if adding 335i brakes to a 320 xi The fronts change to 4 piston Brembos and 340/30 mm rotors (same as sportbrake ) but the rears change to 330/20 single piston. Larger dia. rotors but same caliper as before
Not really sport brake but probably should change the rotor size file.

Makes a rather noticeable difference. Drove M perf brakes for 3 month, mushy, required a lot more force than stock. After coding SPBR, right away, the pedal feel is linear, more direct, exactly what its supposed to be like. I'm assuming the brake system raised the pressure, and the distribution, since the rear calipers are a lot bigger, they can handle more. Long story short, big difference.

I wouldn't simply because you might end up breaking the seals around the calipers. I'm sure the system raises the pressure to compensate for the larger displacement of the calipers.

[rustyminded]

yes i left it back to stock this is a big risk on such small caliper and brakes

Thanks a lot for the guide definitely helped when i was coding my brakes

I think you only need/should do coding for the M Performance Brakes (with 370/345mm Rotors) not for other "stock" setups.

[paul223]

So you are paying bmw for coding? Not engineering? If the two models have same brakes but by coding it makes a good difference in performance of the brake? Lol

Do M Sport brakes have this coding or is it simply for M Performance brakes?

My car have the M sport rotors but single piston, i guess this is for M performance only
when coding there are other options as well which i haven't tried.

the front brakes and msport Mperformance have 4 piston calipers on each

My car is European when i got rotors from usa they sent 312mm front, 300mm rear so it didn't fit, then i called company in usa and they told me because you have the M sport brakes it has two options one with single piston another same size with 4.

I believe he is referring to the /35i brake rotors + calipers. Stock 35i front has a 340mm rotor with a 4 piston caliper. M performance brakes are 370mm discs with the same caliper but a different pad. For the rear, stock /35i brakes are 1 piston, with a sub 300 mm size rotor. M performance brakes in the rear feature 2 piston calipers + bigger rotor.

I have 2NH Msport braking system (blue) is that the same as the m performance?

I want to get some drilled disks (probably aftermarket as I don't like the dimpled ones) perhaps a bigger rotor, any ideas what I should be going for?

yea you can contact frozenrotors they did slotted and cryogenic treatment on stock rotors. result is very good or you can get after market directly from them

They are in the US!!! I need someone in the uk
