not sure where this would fit in- don't really want to join a t bird forum just to ask 1 question.. my friend has a 91 t bird sc this is basically brand new has been sitting in the garage for almost its whole life, his father recently gave it to him but the abs light comes on..he got it to somehow fix itself and for the light to go out but now the abs light came back on and won't go out- also has just manual brakes, the vaccum assist doesn't seem to be working.. any ideas where to look? thanks

 

Check the integrity of the vacuum line to the brake booster.

See if it has a VSS on the top of the axle. If so, replace that $20 part. One bolt.
