There is a reason high performance vehicles do not run drums. Disc brakes dissipate heat WAY BETTER than drums. And as Party Truck said there are less parts, which means less to go wrong. Sure, drums have more surface area to stop a tire, which I'm sure is why big rigs still use them.

You will have to face it one day BJ...discs are superior to drums.


Arlington there is not a doubt in my mind about NASCAR needing discs to slam on every 1/4 mile for 500 miles at 190 mph.
The question here is "does a Wrangler need discs installed at a cost of $800/1,000. to get rid of the rear drums"? My answer to that is, there is little if any gain!
But, as a general rule, are discs on the family grocery getter better than drums? Sure! As I have stated my wifes Suburban now has nearly 170K on it's brakes. And it still stops fine. So repair and upkeep CAN be better with disks.
So "superior" in some ways is POSSIBLE, but in ALL WAYS, and worth the extra money to change from drums to discs on the rear?
