I would do it anyway. New one or not, the OBS MC is garbage.

Hell, mine is used. Paid $20 for it at the junkyard. :lol:

Thanks to guidance from sunlit I burped my water heater line. Or hot water line. Whatever it is that attaches to my firewall.

I like the brake cylinder upgrade. I'm going to have to look into this.

Awww man..! I went to the Pomona swap meet today too..!

Was busy good time man. Walked by and talked to homies at wheel trailer at the back. Almost bought some 22" coys.

On the way home on the 138 my heater valve broke. Lucky I was in walking distance of Napa in the middle of nowhere.

swapped in my NBS master cylinder.

AWESOME!!!!! I recommend this to everyone with the squishy OBS brake pedal.

My pedal is now very firm.:peace:

You need an AGS BLF-26C brake line adapter from AutoZone and obviously a NBS 1500 series master cylinder.

No other modifications needed to fit NBS MC?
