I've been lurking on the site lately, and I've been noticeing that there are a lot of people asking about the Brake Master Cylinder, wierd. Anyways, I am upgradeing my EK to a 5 lug conversion along with a full EK9 suspension this weekend. Was wondering what the best brake master cylinder would be to get. I have to get a new brake master cylinder because my old one is dead. So I thought, hey, I might as well upgrade it in the process. I have read previous post on the subject but have a couple of things unclear. Oh and in case you are wondering, no I am not upgradeing my Brake Proportioning Valve. Here is a list of upgrades that I am getting:

ITR 5 Lug Conversion
EK9 Coilovers (shocks and springs)
EK9 Front Lower Control Arms w/ Sway Bar
ITR OEM Wheels
Civic EX Master Brake Cylinder
or
ITR Master Brake Cylinder

Which would make the better brake master cylinder for the 5 lug conversion:
Any experiences, pros/cons on either of these will be greatly appreciated.

 

If your current MC is 1", stick with it. A direct stock replacement is easiest.

 

NOPE! I still got the stock EJ6 MC. I heard I need a new Brake Booster as well. is the new booster really necessary?

 

Yes, the push rod lengths are typically different. You will also need to adjust the push rod to prevent caliper lockup.

 

damn, good info Dogg thanks. I thought I was just gonna bolt it on and it was gonna work! Didn't know I was gonna have to adjust anything. Maybe I should wait until I get the 5 lug conversion before I change it.

Its just scary as hell, especially when it rains, to have absolutely no stopping power.

 

The Helm manual covers the push rod adjustment. It is a common problem. It is best to address before it is a problem.
