feels like my rear brakes are locking up??
i have a 93 toyota truck, v6.
i did a sas on my truck and ever since, when i press the brake lightly, it feels like my rear brakes are locking up. it makes like a thumping noise and it feels like im dragging my rear tires. also, my anti lock brake light on the dash is lit up all the time. do i have to change my rear abs sensor on the axle?? i looked at the sensor and one of the wires are cut off the sensor. any help is appreciated. thanks in advance.

When I SAS'd my 4Runner, I removed the rear diff ABS sensor and have had no problems like you described... not that this eliminates the possibility.
Did you adjust your LSPV when you lifted the truck? If not, the truck's brake system will have difficulty working correctly.
I am sure you have done this already, but make sure your brake fluid is the correct level.... you may find low fluid trips certain CEL lights.
Of course, it could be rusted or misadjusted drum components, pads, other internals. Check the easy first then consider opening up the drums and seeing what condition everything is in.
If you put new front brake lines for the front with the SAS you might also want to double check the system (and LSPV) is properly bled.

yeah, a friend told me about the lspv but i have no idea how to adjust it...i read the chiltons manual and it says to have a pro adjust it. also, i put brand new brake lines front and back and the abs sensor doesnt have the wires connected to it. i looked at the sensor but theres is no way to open it and reconnect the wires. the fluid, drums and pads are good. so i guess it could be the lspv but i dont know anyone who could adjust it except the dealer. ill try get some pics up of my lspv. thanks for the info. any other help is appreciated.

It's adjusted by raising and lowering that 2 foot rod that sticks out of it. You can disconnect the ABS computer to get the light to go off.
Here's a little write-up on removing the ABS system:
