Carbotech Brakes Feedback?
About two weeks ago I installed the Bobcat 1521's from Carbotech. I had started a thread asking for the type of brakes everyone recommended. I feel like I have an issue going on. Most of the times the car grips pretty good. BTW, I have followed the instructions for the break in procedure. But at other times mostly when I'm in between a shift in manual mode (not that it should matter) the brakes don't seem well. A couple of days ago it happened where I was in between a shift and I had to brake immediately It didn't grip well at all!! Any feedback on this? It scared the crap outta me.

Do you remember if it did with the stock pads?

I've never had this issue with Carbotech street or track pads.
When did you last bleed your brakes?

Ive never had problems with mine. Seems like a minor thing but you might want to get it looked at because the one time it doesnt hold might cause some trouble and its not worth risking your life.

I replaced the rotors with brand new ones from Lexus and followed Carbotech's instructions for bedding them.
That is exactly the problem! The brakes due become hard almost like an abs activation (minus the pulsation).
Yes, manual mode and usually getting on it.
Lexus wouldn't be able to figure this out. On top of that they'll state that the brakes aren't the original ones and blah blah blah.
Does it feel as if the bakes pedal is very hard to press and the pedal is very high? If so I have experienced this many times when auto-crossing my car where you are gong from full throttle applications to full brake (meaning 100%) applications. This is due to the vacuum reservoir for the power brakes being almost completely depleted of vacuum. When a vehicle is at full throttle it is producing little to no engine vacuum, and thereby not able to produce much in the way of vacuum assist. In the accident investigation community this is our feelings with regards to Toyota's problems with reported brake failures and sticking throttles. If you floor the throttle and apply the brakes at the same time you will have 2 to 4 brake applications until you have depleted the available vacuum in the reservoir and loose all power brake functioning, and at best will have the equivalence of manual brakes.

How are your front tire treads and do they have proper air in them???
BTW - I too have scheduled out these Brake Pads with new oem rotors...
Hopefully this weekend.
