advice needed on brake issue

travisjb

I had issues running with bone stock setup and later with ATE blue/gold and Hawk HP+ pads but stock sport calipers/rotors... the issue became progressively more noticeable during sessions, and only occurred at the end of the infield heading into a hairpin, while decelerating from ~100 to ~30. I definitely had enough advanced warning as it progressively got worse with each lap. I would say that I gained ~20-40% stopping distance, so it wasn't like I lost all brake pedal. ie I was never at any time at high risk of ending up in wall but at the same time I had to back down a be less aggressive once it started happening

Having said all that, I'm a lot more comfortable with brakes that work! hence the upgraded bbk

I'm very interested to find out if the ducting eliminates the issue for you... several of us have theorized that the problem with the stock setup is heating (duh!).... essentially calipers and surrounding materials getting excessively hot, not dissipating efficiently, and heat spreading to sensors that input to ABS cpu. As a result, the ABS is pulsing at a very slow rate and causing an ABS-like braking condition but with much longer stopping distances. It feels like stopping on ice with ABS, which is why some have described it as 'icing' or whatever
