I just purchased a 1998 Dodge Intrepid (base) with 2.7L and 55,000 miles (one owner--old lady).
I did not try a "panic stop" when it was test driven. However, later, by myself, I found the hard braking to be inadequate. So I started the regular routine, check pads, (OK) and bleed out all the fluid for new. No improvement. I then realized that a dashboard light (ABS) which is supposed to illuminate for 3-seconds when the ignition is turned on, does not illuminate. So I checked all fuses and found that there were two empty slots in the fuse cluster under the hood. 1) 30 Amp "ABS" and 2) 40 Amp "ABS Pump". Even stranger is that looking into these two open slots, each has only one prong, whereas the other slots seem to all have both prongs. Normally, this would indicate a "null" slot, which was not meant to have any fuse. But this is all rather confusing because of the concurrent conditions, namely, soft braking (no wheel clicking), no (ABS) lamp with ignition on and no prongs under the open fuse slots.
Is it possible that I just don't have ABS and the dashboard lamp was never connected to anything? The owners manual does not seem to indicate that the car MIGHT have ABS, it seems like its a standard, given feature. Thanks.

Thanks. So, no leakage of fluid anywhere, pads all good and only 55k miles. Brake booster probable?
Is the booster vacuum hose connected and in good shape (not cracked or swelled up from exposure to oil)?

Thanks. The hose looks fine. Part of the mystery. The car appears about 8 years old, not 20 as it is. That goes for pretty much everything under hood too.
Running tests on booster, I get conflicted results. One pass and one fail. When I follow directions on Rock Auto web site, it passes. 1. Press and hold brake pedal with engine off, 2. Start Engine, 3. Pedal sinks as it should. (Pass).
Then a youtube video offered this test:
1. Start and run engine in park. 2. Shut off engine. 3. Pull end fitting off booster. 4. Should notice vacume escaping. However, no vacume remaining in booster / hose. (Fail).
Today I noticed one more thing. With engine running in park, I press brake pedal firmly. Sounds like a light wistle under hood.
Thanks.

=> Replace booster.
