Comments about Carquest Wearever Master Cylinder - New:

I have a 1985 chevy k30,6.2 Diesel, 4X4. I needed a master cylinder. When I typed my vehicle information into the computer two master cylinders came up showing to be exact fits. One Part # 1354-1584 stamped 1605 and the other part # 13-1982 stamped 1925. I contacted the online Advance Auto employee and asked them the difference between the two. I was iformed that they both should work they are showing exact fits. Ok so I purchased the one stamped 1605 because it has a larger resevior. I odered it, when it came I bench bleed it and put it on. It didnt work. When I took it off I noticed that the master cylinder end where the hydraulic push rod is inserted is alot deeper than the master cylinder stamped 1925. I believe the difference between the two are this, the master cylinder part 13-1584 stamped 1605 might be to a vacuum power booster and part 13-1982 stamped 1925 is to a hydraulic booster. If you look at the pictures of both master cylinders you can see the difference between the two ends. I hope this helps.
