I have Brembos and the pedal feel and modulation is fantastic compared to stock. It sounds to me like the Brembos in the test were not setup/bled correctly.
Also, I think it's a fair criticism of the test to say that the results should be viewed with skepticism because of the different pad compound. I would like to see the test repeated with same pads, same tires, same surface, and no reasons to question whether any of the kits were installed correctly. |

If anything was wrong, it's more likely they had a faulty product from Brembo IMO And to reiterate once more, the tires and surface WAS the same for all of the BBK's. And they bled the Brembo's twice because they thought it was not bled properly. If they managed to install every one of the other BBK's correctly, why should they suddenly be incapable of installing just one of the BBK's? Of course pads are a very important part of any brake system. The point here was to test the performance of BBK's as delivered on the market by the suppliers. That's what the customers get and that represents the real world performance of these kits. If they all should have been tested with a pad that was not supplied with the BBK, how would that be representative of what a customer can choose from? For instance the PFC has a limited availability of brake pads, because of it's design. Should every BBK be tested with a compound that was available for the PFC, but one that neither of the other BBK manufactures recommends or markets? That would be like testing all cars in a comparison test on the same type and brand of tire, even though the manufacturer doesn't actually sell the car with those tires... IMO, what they have done here is to test a complete product, available to the customer over the counter. |

If I read the OP right, the stopping distance is as measured in an average over 20 stops from XXX-0 kmph. That's actually a pretty accurate metric to measure against how it would perform on track/repeated stops.

Curious, what would you propose as the objective measure of how these kits perform?

I think this brake test is great for what it is. I have two sets of stoptech trophy on my bmw's and am happy with the results but have seen first hand many instances where stock brakes over heat on the track and never an instance with a set of brembo GT. |

The thing that most people fail to realize is 99% of the time, for cost savings, engineers will spec out a brake system that has the capability to stop the car from its top speed, once.

What they describe in the test for the Brembo GT are bleeding problems that I think they couldn't figure out. Nothing surprising about the brembo pads though. Based on my experience with the 365 kit, the original pads SUCK ROYALLY!!!! They are worse than stoptech pads on stock rotors. Also keep in mind that they kit they tested is the EU TUV approved kit with 380mmx32mm rotor and a narrow pad of about 50mm. In the US the kit is 380mmx34mm with 58mm. The tested kit is not available in the US.

Auto Bild also wrote that for their normal testing they "only" did the brake tests for each speed interval 10 times... So every car they do a test of, the brakes has to withstand at least 10 decelerations from 100kph and 10 from 200kph. Not 100% sure if they always do 10 stops from top speed as well, but in this test they did 20 from 250kph... |

+1000000000000000 it needed to be with the SAME compound. i never ever had an issue with the stopping power of my stock z4m CSL brakes, they felt incredible, the problem was it couldnt do it for a decent period without smoke, brake fade and lots of grumbling....

Oh please. Everyone here wants to tailor a test to what they want to hear. Ilia is not right and neither are the above posters. What's hard to understand? The test was done with the supplied pads, the same pads you get when you buy the kit. Why on earth would they test them with all the same pads? For the test the car is the constant and the brakes are the variable. People are unhappy to hear the brembo didn't do well and now want to criticize everything.

Dunno how long the Brembo GT kit has been sold for, but surely if the Brembo's were that bad, word would have spread like wildfire and they would never have sold any!

How would that be representative of the product you actually could buy from the showroom? Sure you can change tires AFTER you have bought the car, but so you can with brake pads on a BBK. Point is that they test what you actually get supplied from the manufacturers, not how it would perform if you modify their BBK. Just like any track test comparison of a M3 vs RS5 vs C63 AMG is done with the tires as fitted from the manufacturer, so was this BBK test done as regards brake pads. This is how they perform out of the Box. Not how they could have performed if you changed the product they delivered... Last edited by Boss330; 11-26-2014 at 08:37 AM.. |

AP have never supplied their kit with the Pagid RS29. It comes with the apf404 pad. I just don't like the inconsistencies I'm seeing, how many more where their that we aren't seeing??
however i can't defend the brembo on a 20 stop brake test, that is poor performance whatever the pad it comes with, that SHOULD be able to do better than stock on a brembo bbk it would have been nice to see another section adding the rear kits on to to see how much if any difference that makes.
