the car needs to be scanned for abs codes. for this you need a scanner tool some vettes have self diagnostics where you can retrieve codes with the cars info center check google self diagnostics 1991 chevy corvette. if there is a bad sensor or control module the light will just come back on until problem is fixed need code to track problem.
you first have to buy the new battery for the trial blazer and make sure its the right battery. first you have to unplug the both slots that hold the battery and the battery should slide right out of its box where its being held and also make sure the truck is off when your doing this if not you can eletecute your self.
Key on, off, on, off, on.
Open the rear hatch to access the mounting scews for the tailight assembly. Remove the scews and drop out the tailight assembly. The rest is self explanitory unless you have a fried circuit board for the taillights.
If they are drum brakes then yes they are self adjusting, But they never adjust themselves right. You will need to adjust them. If they are discs brakes then there is no adjustment. ( replace pads)
