JensenHealey Posted April 4, 2017 Share Posted April 4, 2017 (edited) I purchased a Mack Midliner truck early last year and the title says it is a "1989 250" but I have a copy of the old craigslist ad and that says it is a 1990 MS200P Is there a way I can actually identify it one way or the other? It has air drum brakes if that means anything. Edited April 4, 2017 by JensenHealey add photos Quote Link to comment Share on other sites More sharing options...

kscarbel2 Posted April 4, 2017 Share Posted April 4, 2017 Your truck's VIN, the last 6 numbers after the zero......does it begin with an 8 ? Quote Link to comment Share on other sites More sharing options...
JensenHealey Posted April 4, 2017 Author Share Posted April 4, 2017 No, the last six characters of the VIN are 200139 Is there a VIN decoder that would tell me more about the truck's equipment? Quote Link to comment Share on other sites More sharing options...

Then you have an MS200P, based on the VIN, with air-over-hydraulic brakes. Be sure to flush the brake fluid with new. I'm sure they've been ignored and corroding condensation is in the system. I imagine at this point, wheel cylinders (in the states) are quite expensive.

JensenHealey Posted April 5, 2017 Author Share Posted April 5, 2017 So is flushing the brake fluid a complex job to do? I am an european car specialist so I have never worked on a commercial truck like this before. Quote Link to comment Share on other sites More sharing options...
fxfymn Posted April 6, 2017 Share Posted April 6, 2017 Quote So is flushing the brake fluid a complex job to do? Not any different than doing it on a car. I use a pressure device (pump can) to inject new fluid into the master cylinder while I open the wheel cylinder bleed valves. Run fluid out of the bleeders until it is clear or you just figure it should be the new fluid coming through. Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!
