2nd Gen Non-Engine/Transmission 2500/3500 brake size

Do the 3500 trucks have bigger brakes than 2500's or are they the same size???

The 3500 are larger than the 2500. I think that the 3500 is the 12. 5" brake shoes and the 2500 is the 12 " shoes. I would have to go check the service manual but I think that is correct.

What year trucks are you talking about? For model year 2000, the 2500 and 3500 Rams both have 12. 125 X 3. 5 inch rear drums.

Thanks Thomas,

once I reviewed my post I noticed that I had the sizes bass akwards. It should be 3 and 3. 5. That'll teach me to write and post without preview.

What about trucks like mine '02 with rear disks are they the same as 3500 trucks, and is everyone saying the front brakes are the same size?? on all 2nd gen trucks

Good question, I would assume that they have the same size brakes because they are both rated to pull the the same trailer weights and the 2500/3500 weigh almost the same.

According to my 2 day old service manual, the 2500 calipers are 45mm and the 3500 calipers are 51mm (I'm not sure if this is the diameter). The bore size is the same though, at 25. 4mm. In short, the 3500 is bigger.

The 3500 should have bigger brakes,due to it having a higher GVWR,The trailer rating has nothing to do with the brake size,the trailer has its own brakes,at least it should. The 2500 needs to stop 8800lbs max,the 3500 needs more brake to stop 11000.

I saw the same thing that Hiilcountrykid did in the service manual.

It looks like the front calipers are the same between 2500 and 3500. The rear calipers are different between 2500 and 3500, but the rotors are the same size. If anyone else has the 2002 service manuals look on page 5 - 2 . I guess the 2500 have a larger safety margin in the braking department. When the time comes for rear caliper replacement I hope that I can put the 3500 calipers on my truck.

Ooops! I forgot to mention that is only on the rear brakes. Other than the rear calipers, the rest of the components are the same.
