I'm planning to swap my DX brakes with SI brakes. do i also have to change the master cylinder for this to work?

Also, how much improvement over stock should i be expecting?

thanks

i upgraded mine to the LS/GS-R brakes...you go from the 9.3" rotor to a 10.2" rotor and you do notice a difference if your road racing or u have to brake hard in any other kind of situation... Si brakes are the same size

I do road race. I was under the impression that changing the drums to discs would be somewhat beneficial?

kinda but not really even with rear disk breaks the front still dose more brakeing.
im not saying there is no difference but its not a huge improvent.

he thought you were talking about the fronts. i did the swap on my 90 civic ex sedan

If by Si you mean the 99-00 Si, and by DX you mean the 96-00 DX, well then that is a perfect brake upgrade. The fronts are an easy direct swap, the rears are the same and the e-brake cables are a perfect fit! As far as the MC, upgrading it would be beneficial if you upgraded your frotn brakes.

Now as far as the prop valve, YOU DO NOT need a different one, your stock DX prop valve is the same exact one as the Si prop valve.

I have done this swap in 3 EK's of mine and I loved it each time.

it improves braking by little bit, since the front does most of the braking anyways

I know this thread is from5/2009, but I'm currently wanting to do something similar to this too. 99-00 full suspensions onto a 92 civic Hb dx. Will this be a direct fit? or is this a no-no..? thanks.
