Brake Code Help

[1956_4x4]

Does anyone happen to know the brake code (JB7, JB8, etc.) for a M1031 (I think the M1008 would be the same)? I'm looking to change some of the front brake components, but need the code for the system. I usually find it on the slip in the glove box, but this slip doesn't list the brake system.

iirc its JB8, but dont qoute me. What parts are you planning on replacing? the only differences would be in the vlaving of the Master Cylinder and the proportioning valve.

I'm thinking it's a JB8 also. The JB8 is a 10,000 pound system and that's what my VIN indicates. I was just looking to replace the front pads and rotors, but I had three different parts houses tell me they had to have the RPO code.

I thought so too, but after the third parts place I figured I had to be wrong....

Ever sence the movie Fast and the Furious I can no longer walk into a parts store!!!! *sigh* They all think stickers and LED's make cars go faster and wouldnt know a 1 ton front axle from a drive shaft if they tripped over it!

Haha, the demise of the good counter guy! There is a little local parts store I frequent in the area. The first time I went in, I knew I was in the right place. Dude went straight to the catalog, no sissy parts computer. On same note, went to Advance Auto Parts, asked for GL1, got silly look, then I left. Went to little guy store, asked same, he replied, gallons of pail?
