Car is currently on jack stands. New clutch installed and Everything back together. When running, in gear, and the clutch held down, the wheels start to spin and if I hit the brakes they stop the axles and kill the engine. What could it be?

95 civic ex d16z6
5spd transmission with stock flywheel an oem replacement clutch disk, pressure plate, and throw out bearing.

 

same reason as when you come to a stop at a light and dont push in the clutch...

 

He's saying even with the clutch pushed in the car still dies once he brakes.

 

Correct. It seems the slave cylinder has about 3/4 inch of backwards play when the clutch pedal is all the way up. And Only moves about an inch when the pedal is pressed. I've bled it multiple times with no change. It seems like the throwout bearing isn't coming all the way back on the clutch fork for some reason.

 

u need to adjust ur clutch if its a cabe trans theres a decent video where they adjust one on an integra. if it a d series with a hydro clutch https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/honda-clutch-pedal-engagement-too-high-2981264/ scroll down till u see ronj's post he has the page from the servive manule to adjust a hydro clutch

by the sound of it ur clutch needs to grab higher up because u have what is known as clutch drag
