ok, here is the deal: I have powerslot slotted rotors on my car with some pep-boys pads (it was the last warm weekend last yr and i forgot to order pads and needed the rotors installed asap so i just did it). i notice when im going fast and hit my breaks, sometimes my "no trac" light pops up on my dash and the peddle/car gives me the same feeling as when ur sliding on snow/ice. Kinda like the breaks give out. This only happenes when i press my breaks hard/sudden while traveling highway speeds. mind you that my tires do NOT screech when this happens. is this just my ABS kicking in?

This is f'in annoying, and down right scary as hell when it happens and ur not expecting it to (like tryin to advoid an accident). is this a break pad issue; will a set of HAWKS solve this? Or is this a caliper/piston issue? i have twin pistons up front and single in the back. Listen, i want my damn car to "stop on a dime and give me change" when i hit my damn breaks, i dont want to feel like im sliding on ice and feel like my breaks are giving out on me.

Case and point: it was raining in april (go figure) and some lady slid out going around a corner and hit the curb. Well traffic went from a 60 mph cruz to a dead stop and i hit my breaks and started to slide around the corner. Im not stranger to sliding (on purpose) so i want able to handle it, but my car wouldnt stop. That damn "no trac" light popped up and i slid. There was no screech, so i kno my tires didn't break traction.

how do i stop this ?

I'm pretty sure that is the ABS. If you really want to stop on a dime with these cars though, I'm pretty sure you're going to need to upgrade at least the front brakes. The Corvette conversion kit is probably your cheapest solution, but if you are going to spend that kind of money and can afford to, you might as well step up to a Brembo or Wilwood kit.

wtf goods that??? Id rather have the car able to stop; then and ONLY THEN kick on the ABS so i can steer to avoid it.

so, 4 pistion calipers, steel braided lines, and pads upgreades wont do any good. i have to go bigger?

Pads and rotors will not cause this issue. I would scan for codes and monitor the car with the scan tool while driving. Even before I did that, I would pull the wheels and inspect the brakes. Look for anything leaking or abnormal. Maybe a wheel speed sensor went bad.

Nightrydass

like i said it ONLY happens when im going highway speed and i have to hit the breaks hard (like someone infront of me comes to a complete stop b/c they r dumb) and i have to go from like 45 mph to 5 mph in 30 ft or something like that. it is like the calipers cant grab hard enough to hold onto the rotor and stop the momentum.


btw, there is no SES or Check Engine light on, or one that even flashes on. and if it was the wheel speed senor, wouldnt it happen while driving?

Ralls

Not exactly. Speed sensors are weird some times. I worked on a customer car that would throw the ABS light on when you got to a complete stop. Like it would come on right as you got to 1 mph. Replaced the speed sensor and all good.
It might not be it, but that's one logical answer.

its not the "ABS INOP" light, it is the "NO TRAC" light

I know when I lost traction in the snow, my low trac light came one. I don't have traction control either. ABS Inop light lets to know if the car notices something wrong with the ABS.

Nightrydass

yea it is my "LOW TRAC" light that came on, Id like to not have low traction. lol. Seriously tho, that snow thing happens to me in the winter, so u kno the "feeling" im talkin about. if it was my "ABS INOP" i'd be worried.

Do u have an recomendations on high performance pads? I have heard that the dust from HAWK pads can kill your rims.

I don't have the $$$ for a big brake kit yet, so if i can "beef" up my stock system that'd be nice. I already have PowerSlot rotors...any suggestions?

Hawk pads are what I have. Just as they say, it was like night and day. Whatever stock one's that were on the car had to get really hot to bite. But the hawks grip right away. The ceramic hawk pads don't dust hardly at all. I have black rims so brake dust will easily make the color dull. But it takes a weeks worth of driving till my wheels begin to look dirty. Do you have an LS1? Your brakes are a lot better than my LT1. I'm more of a straight liner, so I don't care about nice brakes.

Nightrydass

yea its an LS1. Powerslot recomends HAWK pads, but they dont say weither it is the regular ones or the HP series. So i dunno what to get. I guess i can go with them, steel braded lines and see where im at until i have the money and want to buy a brake kit.

Also, does ANYONE sell 4 piston calipers to fit stock size rotors and use stock mounts or am i stuck with 2 piston till i buy a big kit????

IF U HAVE A LOW TRACTION LIGHT...you have traction control...

Ralls

iTrader: (32)

No, thats ABS kicking in, not traction control. They sound the same but aren't. If my "low trac" light comes on, then the brake pedal will pulsate, which is ABS. Traction control is from spinning the rear tires. I can do that all day long and the PCM will never know.

I had the feeling too back with 8K on the car, turned out the ABS went bad and they replaced it under warranty. Same symptoms. Worth getting checked out by the dealer if you can. Since then, car stops fine.

Nightrydass

I don't think it is an ABS module issue; the car stops fines normally (99% of the time), it is just under really sudden hard stops the "NO TRAC" light comes up sometimes. It doesn't ALWAYS happen, it has to be a really sudden highway speed stop. it gives me the same feeling like im sliding on ice/snow. there is also no "SES", "CHECK ENGINE SOON", or "ABS INOP" lights that are on or that even flash when it happens. If it was a faulty unit, i'd imagine that the "ABS INOP" light would at least flash when it happens if not stay on always. the only light that flashes is "NO TRAC".

I could flush the brakes, i know powerslot recomends DOT4 and i believe i have DOT3. I personally never bled or had the brake system bled by anyone and it is black as ****. I could also throw on some steel braided lines and put some HAWK pads on it like powerslot also recomends.

I have some powerslots and hawk pads and theyre fine when its warm. But I had it out a couple times over winter. Real cold and a lil wet and the things didnt seem like they wanted to work.

We can keep talking about it, but you need to do something to fix it. Have you inspected your brakes yet? Scan tools out there will monitor wheels individually so you can figure out if something is malfunctioning on the left or right side. No need to change to DOT4. All it is is a higher boiling point.

Nightrydass

whats do you mean?

Nightrydass

yea nothing is bent or broke or leaking

Nightrydass

thank you guys for ALL your input. I think next weekend ill do the pad swap, bleed the system (since i haven't done it yet, and dont think the previous owner ever did either), and put the steel braded lines on. then ill see where im at
