On my MRS3 Trophy, I have slotted Brembo discs on the front and Brembo pads as well, now may be running for 40000 kms ( my daily job route is both ways 70 kms cruising almost without braking) When raining, with considerably water on the road, the brake was terrible all the time from the beginning. It needs at least half a second till the brake starts to grip, with 100 km/h you need 30 meters to get response from the brake. It´s a feeling like Aquaplaning on the discs. If i force the brake by applying more pressure, the brakes are juddering with a strange noise, it´s not possible to meter the brake effect as smooth as I want with this juddering vibrations. They are not to feel in the steering, just to feel on the brake and the noise is strange. Did you experience those behaviour as well , particularily with slotted discs? In the dry, the brake is ok, no problems at all. The pads are not worn as well as the discs. Any ideas?
