I can not find a definitive answer to this question.

I just swapped the brakes in my 94 CX Hatch to the 94 Integra GSR Discs on all four corners. I also swapped my MC to the 15/16ths one from the 91 Civic EX.

Now for the question, I have a 3030 valve in my hatch (stock) and I bought a 4040 off of a 93 Integra but I am having issues removing the brake lines from the Prop valve in the car (and yes I have the right tool, the tool is stripping the nuts!) Is there a big difference between the 4040 and the 3030 if I have the big MC? Whats going to happen if I dont change to the 4040?

Thanks,
Brad

youll still be able to stop.... but you want the correct prop valve in there to take advantage of the new disks... get it swapped asap

Damn...My car hates me lol. I guess I will try and figure out another way to get those lines off.
