Swapped Dually axles to SRW axle, now back brakes skid almost every stop sign

[Rumble]

i can do that, the only reason i hadnt was because i thought drum brakes were always supposed to be adjusted to where there is just a bit of drag when you're turn the drum,
i can back em off though, it was just interesting that this happened on another vehicle with a similar swap, so i was wondering if the part # is the same for the proportioning valve for a DRW or the SRW
thanx for the reply
