Instant loss of brakes???

    I'll try to keep this brief.

    Driving along yesterday and following an older lady. Light turns yellow, and of course she slams on her brakes. Well, she's in a modern Audi and I'm piloting an old Suburban. Stepped on the brakes, applied full pressure. The anti-lock function worked, but once stopped I notice that the pedal is touching the floorboard. For the remainder of the drive home, my brake pressure is almost nil. The brake light is on in the dash now. I unplugged the ABS module and the ECU. Checked the fluid resevoir, brake lines, everything I could think of. I've never lost 75%+ of braking function after a hard stop.

    Any ideas out there?

    90 Suburban 4x4 - had full brake service and overhaul last summer.

    After some testing, I found one of the rear lines exploded. Initially, I found no brake fluid spray yesterday. After applying pressure on the lines today, there is a huge leak spitting fluid all over the axle and differential. Damn. :grrrrrr:

    That sucks when a line lets loose... Glad you found the problem.
