Car won’t move after a sudden hard stop

Thanks JARblue, I am not sure it’s the brakes but I’ll have a look. I am thinking of maybe going with oem pads. These leave a pad imprint every time I wash it . I do want to state that after the car came to a stop it would not accelerate it just revved for a second or two and then got going. It felt like it was trans related but then again it might be in my head since I just got the fluid changed 2 days ago.

Sounds like a possible trans fluid level issue. I have the Stoptech sport pads and they weld to the rotors after a wash if I don't dry them out.

If I wash my Z and leave sit overnight. My Carbo's will stick to my RacingBrake rotors. Nothing serious. They will break away easy. And there is an outline of the pads on the rotors. Around the block one time and it's gone.


OP, has this happened before?

Yes, the pad sticking to the rotor issue I found out about when I bought the Akebonos to upgrade my stock calipers. They are coupled with the Z1 2-piece rotors.

The issue with the car not rolling after the hard stop is something I can't know for sure, as I just noticed it yesterday. When I bed in the brakes after the initial install I never came to a complete stop.

Yesterday is the first time I decided to stop as my phone had fallen out my shorts. That's when the car wouldn't roll forward. I was able to trigger the symptom at least 3 times.

I don't want to sound like I'm blaming the trans fluid change but like I said before the car revved freely for about a second or two then got going. It didn't feel like the time the pad got stuck to the rotor. I'm going to try it again tomorrow night when I get back from the gym to see if it acts up again.

The only way to get the pads to stick really hard is to get the rotors glowing red hot. Coming to a stop, and keeping your foot on the brake pedal until the brakes cooled completely. You're not doing any of this.

What you are describing is a tranny issue. You're coming to a stop. Step on the gas pedal. The engine rev's up, then the tranny hooks up. and then you move.

Yes, exactly as you summarized it in the second part of your post. At least it’s how it feels to me too. I’ll still do a couple of hard stops tomorrow night and will update on the symptoms. I will definitely get a hold of the shop if it persists. Thanks for your help.

OK, so it is definitely not the brakes I don’t think. I went out just now and applied the brakes in a mild and hard fashion and the car did the same thing. It stood still for a second or two then hooked up and rolled forward. I captured it on video from a decent stop. I hope the trans isn’t messed up, I was trying to prolong the life of it by getting that fluid changed

I don't know how to check it unfortunately
I'll send the shop that performed the work an email and get their thoughts too. I didn't want to bother them with my assumptions if this is normal. So I figured I ask here since this forum has always been a great source of help. Thank you.
