Hi Guys - Is there a way for me to figure out what size rear brake drums I have (9" or 10") without pulling it off and measuring?? I have a 1999 Ranger Supercab XLT Sport, 4X4, 4.0L, with ABS.

Thanks...

 

The 4.0L trucks have the 8.8" rear diff., and so they have the larger brakes too. One way to check though, is to look at the brake drum itself. The size will be stamped on there (in mm.) and you can then just convert to inches.

 

Yup, there it was 256.3 MM which ~10". Thanks!!

 

Just beware if you are replacing the wheel cylinders. On my 10" brakes the replacements I got had 1/4" fittings but the lines were only 3/16". I had to get some adapters.
