Hey guys I swapped GSR front brakes on to my CRX HF and I was wondering if I need to upgrade the master cylinder or brake booster for it to work. Can I get away with with leaving everything else stock? Or if not, what else do I need? I've already done the swap just making sure I'm ok before I go ahead and bleed the system.

Btw my OEM master cylinder says 13/16th on it but I've got a second one off the parts car I originally took the GSR swap off of that isn't labeled at all. I can post pics if necessary.

Just get a m/c for a 4-door EX. Bigger bore and bolts right in.

Does ABS vs non-abs matter when upgrading the MC?
All ive got around here are ABS cars

You can use ANY ABS or NON ABS booster and MC together. You cannot switch ABS booster with NON ABS MC. I have an ABS (290v) booster/MC on one car and a NON ABS (260v) booster/mc on my other car. If you have a GSR that you are swapping your parts from you can use the booster/MC combo.

And the EX MC is crap compared to the 260v and 290v booster/mc setups.
