Brake question. Nephew purchased a 91 TC (which has been fun spending time with him). Trying to assist with brake issue but am head scratching. ABS amber light is on. Drivers side rear and passenger side front calipers are locked up (pistons will go out, but not retract). Can manually compress pistons. No leaks. Brake pedal / pressure is normal. Not certain what to check first. Don’t have a code reader - is there a way to troubleshoot without that? Edit: The pump does turn on.
