2nd Gen Non-Engine/Transmission temporary brake failure, nearly wrecked!

[telliott]

went to step on the brakes and they went to the floor for a second before they had pressure. it was only for a second, then they came back to normal and luckly i got stopped before a wreck. they are working fine now, but the ABS light is on as well as the "brake" light on the dash is on. smarty shows no codes. Anyone know whats wrong?

Had the same problem in my truck and my dads. We both have 12 valves not 24 though. But there is a load/height sensor on the driver side rear on the inside of the frame above the rear wheel. There is a small piece that connects the main line to this little pump. You may want to check it. Both of ours had rusted and busted out under pressure. Yours may not be busted completely, but possibly has a small leak. May want to check that along with the rest of the line for leaks.

Hope that helps,
Travis

abs codes can stiill be set and not show up. clear the codes anyway.

A bad master cylinder can cause this symptom too. Happened to me.
