28 vs 35 brakes?
Sorry if this has been discussed before but I didn't find the details. I have seen some comments that the 35 has different brakes from the 28, if anyone has the details of the differences I would appreciate it

What's interesting is that RealOEM lists larger brakes up until 4/12 production for the 28iX.
X1 28iX - front - 330x24 until 4/12 and then 312x24; rear - 300x20 X1 35iX - front - 348x30; rear - 336x22 |

Surprisingly though, as the master cylinder is the same, some clever e9x 328 owners actually have purchased 335 brake bits from those who have upgraded to big brake kits and have bolted them onto their 328s without issue. |

I don't know about stopping distance but I am still amazed that there is almost no brake dust due to the ceramic brakes. My E93 wheels are dirty in 2-3 days with 50 miles driving while we can drive the X1 hundreds of miles and the wheels are still clean.

Great point, the X1 does not dust nearly as much as any of our previous BMW's. After driving both the 28i and the 35i, the brake pedal feel on the 35i felt much better, same as the F30's we drove. I'd suspect that any 328i braking advantage in magazines was due more to different tires than the lighter weight of the 328i and would also more than disappear after repeated stops.

When was the last time you put pads on the e93? I've been wondering if the new composition has been offered as a replacement for the older models?

We got new pads and rotors on our 1er shortly before selling it and if they were better, it was a really, really small difference.

I'm used to the brakes on a 2010 335 and when I test drove a X1 sDrive28i the other day I thought they felt a little underpowered. Sort of reminded me of my old 325.
I plan on driving an xDrive35 today, I'll let you know how they feel. |

Yeah, you do give up that initial bite that the old dusty pads had, but frankly, I'm lazy enough to admit that it's a trade I'll gladly make for not having to clean the @#$%*! wheels every three days.

Hmm, I actually like the pedal feel and feedback much more than the 135i's brakes, which were very disappointing given their design. These feel very similar to my M Coupe's brakes, which have been my favorite both on the street and the track.

2008, but they all have the same brakes. Stopping distance were okay, but pedal feel and heat soak were a big problem with them. This has been common with recent Brembo fixed caliper setups. The ceramic pistons on the 135i, pads on the 370Z and general design on the STI and EVO setups have all caused various issues.
BMW's normal single piston design may not be glamorous, but they do work fairly well. I'm not sure what BMW's goal with the 135i brakes was, maybe they just knew it would be a relatively small sample and they were testing whether multi piston setups made much of a difference in terms of the covered maintenance interval? I suppose they do seem to have adapted more multi piston setups, with the F30 335i going to them and the M5. I assume the F80 M3 will come with them too. |

So would the BMW performance brake system make a huge impact performance-wise?
+ Is it compatible with my double set(I bought a winterset at half the price too) of BMW-OEM 17 inch rims? |

The actual brake distance to 0 isn't as important as many seem to think. When did you see an accident where the vehicle failed to come to a full stop, not counting fender-benders by tailgating idiots? What's more important is the ability to steer well while decelerating. That way you don't get that fender-bender because you were tailgating, as you can avoid the vehicle that stopped. And you avoid the risk of some of the more serious accidents too, like hitting an oncoming vehicle (or a tree!) dead on because panic braking reduced steerability. |

Braking from 70-0mph: 189 feet
I'm confused. I have not seen any other reviews slam the X1's braking, yet. http://www.caranddriver.com/reviews/...8i-test-review |

70-0 in 189 is pretty bad. While 10 or 20 feet might not make the difference as noted earlier, you do feel that difference and that feel inspires confidence and having confidence when the shit suddenly hits the fan is a good thing.
