Rear anti-lock and brake warning light

[a-5 freak]

I was driving home today and all the sudden, the brake warning light and the rear anti-lock light came on at the same time. i pulled over to the side of the road and i had lost significant brake fluid from the master cyl. there were no signs of leaking anywere on the truck though. so i decided to drive home 2 miles away (slowly and carefully) the brakes were mushy and whenever i gave the brakes a good amount of pressure, the back wheels locked up. whats going on?

Sounds like you've blown out a brake line somewhere, if you back brakes are locking up you might have blown a front line, or a wheel cylinder might have let go in the rear drums and the fluid is causing the shoes to lock up.

well i just looked at the abs hydralic assembly and it is all sorts of leaky. aparently its quite common.
