The manual is vague whether this particular wagon has an anti-lock braking system or not. When I turn the ignition key "on," there is no light at No. 3 position, the location of the ABS light. There must be some way to hard ID this. Thanks.

 

look at the master cylinder to see if there are pipes going to an ABS modulator before going down to the wheels.

 

Thank you. Pipes. As in metal pipes. Not hoses, then?

 

Yes, thin metal pipes, ABS box should be on driver side engine compartment, may have a black plastic cover with ABS on it. 1990 may or may not have ABS.

 

Thank you, again. I wish I could find the invoice from the last time the brakes were repaired, because I have to wonder how another mechanic would know that this vehicle may or may not have ABS, and, hence, what rotors it needs. I'll look in the morning. I should look under the Power Steering Reservoir area? I should have asked.

 

Well, a mechanic or anyone can tell easily if there is ABS... The ABS module is in front of the strut tower. The Volvo models of that gen especially may have one of several brake systems thus the confusion with parts, could be frustrating especially as they age...

 

Yes. Thank you. I verified that my vehicle does not have the anti-lock braking system.

 

Question solved. Ending thread.
