you got air in your system thats why you have a spongy brake pedal.

Hydraulic fluid can not be compressed while air can. Thats why you feel that spongy pedal.

Flush the brake fluid. Then bleed it. If that doesn't do it. You might have a leak on one of the lines.

as far as aftermarket or performance MC dont look because nothing is going to perform better than OEM for a master cylinder if you can even find a performance one. a good place to get it is just at a local auto store and you should be all set...

In which order did you bleed your brakes?

And what car is it? Older Integras w/ the 3-channel ABS require a different order than the newer 4-channel units.

Which year was the change? I knew of a difference it the abs system but thought it was more of a layout change not an actual design change.

98+ Integras (all) and the 97 ITR came with the redesigned 4-channel ABS, which used a smaller modulator unit, and used fluid from the main brake MC reservoir instead of having its own reservoir. The change coincided with 98+ ITR's in Japan being offered with HID headlights, as the smaller modulator unit made room for the ballast on the back of the headlight housing.

I've seen different methods posted.

I believe the 98+ helms mentions:
Driver Front
Passenger Front
Driver Rear
Passenger Rear

IIRC - 94 Helms
Passenger Rear
Driver Front
Driver Rear
Passenger Front

I believe some mechanics are taught to bleed from farthest to closet from the master cylinder.

Personally, i have been using the 98+ method.

That's the old-school method for cars without ABS.

That was the order specified on my old 89 Camry w/o ABS - pass. rear, driver rear, pass. front, then finally driver front, going farthest to closest to MC.

Bleed the brakes once again and inspect the lines. I doubt you'll need to replace the lines.
