It's been 3 years since I took the Z to the track, the car drove like how I remember and I ran reasonably well. Here is the problem I do have. At every corner of the track, the brakes seem to behave differently. I would either get no pedal, stiff pedal, stuck pedal, pulsing pedal or whatever. Every corner is different, I had absolutely no faith in them what so ever. Unlike the handling, the brakes definitely felt worse than before. It is getting to a point where it isn't safe anymore, I want to see if anyone can help me figure out what exactly is wrong. I was doing Laguna Seca, I figure I will give the turn by turn break down.

Before I start, I do have the brake duct kit with Carbotech XP10 and XP8 and Castrol SRF fluid. Fluids were all fresh, pedal stiff as a rock. At no point did I get fade, so I don't believe I was overheating them. I run RS3 and I am on stock power, just springs shocks and front sway bar

Back to the track.

Going into T2 at 110mph? Braking at a little before the 3 marker, the pedal would initially not bite and then bite hard to slow the car with a little wiggle side to side. As I downshift, I can feel the pedal staying low (without me pushing it) and then it would eventually come back up as I get ready to go back on the gas. This is already weird behavior 1. The bite of the brake is just weird. I hate how I feel the initial bite, nothing and then the brakes just grab hard.

T3 and T4 I barely tap the brakes, so skip those.

T5 is a huge problem area for me. As much as I try to hit the brakes after the bridge, a lot of times the car would just go into semi ice mode where the brakes would bite and then it would let go and eventually come back again. I tried to go in with the pedals soft and then hard, both ways they would do the same thing. Like T2, I would get the initial soft bite but instead of the hard braking after, the stupid brakes just doesn't seem to grab (I don't feel anything weird with the brake pedal).

T6 I am too busy pooping my pants trying to take it as fast as I can, not on the brakes that long other than setting the car up.

T7 is another problem area for my brakes. As I hit the brakes hard, every lap the car would do something different. Sometimes it feels like it would just keep going, while some laps the car would slow down and make the corkscrew. I do seem to recall I have hard pedals every time, but it is scary when you hit it and the car simply doesn't slow down.

T9 and T10 the pedal feels okay, but once again I really have no trust in them as they can vary in feel every lap. Braking distance is very short anyway

T11 hairpin is as big of a problem as T5. Instead of the initial bite and then slowly not grabbing, I usually get into this turn with no bite and the car would go straight into ice mode. Couple times I feel like the car would just keep going straight and I used the clutch to slow down a few times as self preservation. I didn't try to reapply the brakes as I am too busy not crashing, but the car does the ice mode basically every time in this turn no matter how hard or soft I hit the brakes. Without it, I feel like I can brake as late as 2, but I usually brake at 3 marker just to be safe.

Anyway I love the car, but the brake problem is really scaring me. Anyone have any idea as to what it could be? I guess I can try the pads first, but could the ABS computer be going dead too?
