Rear Brake drum size ?

Hi
How do I know if I have 9" or 10" rear drum brakes on my 98 2wd ( 2.5 litre )

Thanks

Is yours an extended cab?

Should be 9 inch.

Usually only 10 inch standard if its a 4.0, 4x4, or extended cab.

Best bet would be to measure but the two look quite a bit different. 9" ones usually have ribs/fins cast into them and the 10" ones are smoother.

9":



10":

The size (in metric) is stamped on the drum, or just use the pic above. Check your parts at the store, I have bought rebuild kits twice and both times they came with mixed parts for 10" and 9" in the same box.

new parts

The new drum I purchased doesn't fit over the new shoes, I have no room for adjustment. I assume that if I bought 10" shoes, then it stands to reason to buy a 10" drum. Right? Any help would be appreciated
