doing cobra rear swap--- do i need to change master cylinder?

dragstang86 · 07-28-2003, 06:00 PM

What else do i need to change to make this swap work? the rear is a 4 lug 93 cobra rear and it is going in my 90 lx. Do i need to put a 93 cobra master cylinder or metering block or proportionary valve or anything else in it? Right now i just have the complete rear along with the rear brake lines and parking brake cables.

thanks for the help

You should be fine if you get a '93 Cobra MC, although with a stock booster, the pedal will feel a bit firmer. The metering valve on the '93 GT & '93 Cobra were the same, so you could probably get one from a salvage yard relatively cheap!

I did a similar conversion, but added the '73mm calipers up front and went with the SVO MC (1 1/8" bore - I think the Cobra's is 1"). My tech article should be up soon with a bunch of pictures and a nice parts list!
