2002 GMC Yukon XL 1500 Q&A
2002 GMC Yukon XL 1500 Question: Which brake lines go into which port on the Brake Pressure Modulator?
clean it i think it has LR, RF,LF,RFmarked on box - delane 72 garage and body shop
I looked in the manual and did not see any brake line schematic. So, this is an old trick that I learned from working at Dealerships. Go find a similar vehicle crawl under and draw a picture, it sounds primitive, but it has saved my but a zillion times. So, in your case go to a used car lot, there has to be a few Yukon/Suburbans for sale that are the same body style as yours, it is one of the most popular vehicles ever made. - dandd
