When we last left our heroes , they’d been lightly fucked cuddled by RockAuto sending us the wrong brake hardware for the marathon wrenching session on my friends neglected D21 .
!!! UNKNOWN CONTENT TYPE !!!
Further investigation reveals they seem to have sent us the shoes and hardware for the 4WD version. Why does the 4WD version have slightly different everything? Who can say? Only Nissan, and I suspect they’re not sharing.
Luckily we had plenty to do while we wait on new parts. Specifically we replaced all three (yes, three) brake flex hoses and pulled the bench seat.
The former was pretty easy.
The latter was also easy but surprisingly gross. Thirty-two years of spilled soda and fast food seemed to have accumulated under that seat and it took all the 409 in the house to make it (and a fair amount of paint) go away. After that dried I lightly sanded any rust (there was very little) and hit it with rust converter. Next we’ll prime that and any other questionable spots and cover it with butyl .
Unfortunately , an ice storm in OKC, the closest Amazon fulfillment center, means all of our replacement parts were delayed indefinitely . Luckily AutoZone had everything we needed, a lbeit at several different AutoZones. After successfully solving a mini traveling salesman problem, we had new shoes and springs to replace the wrong ones and the Amazon ones.
Which, of course, means the Amazon ones arrives.
SHOES FOR DAYS.
Anyway, we then set about building the drum brakes.
Something neither of us has done before.
It... went OK.
As mentioned previously, the factory service manual (FSM) and the H aynes manual that is based on it are both pretty crap. Oddly the Haynes seems to be more verbose than the FSM. In either case, both were pretty tight lipped about what goes where when, so we winged it.
And only had to take it apart like... three times before we got all the right springs in all the right places. So yeah... pretty ok.
N ow we appear to have a fully intact brake system with new everything (front discs were done a few months ago) ready to bleed!
But at that point it was late and whiskey was calling so....
Until next time!

Nice job. Drums are such a pain in the ass. I was taught to only disassemble one side at a time so you have the other as a reference. I’ve also learned to take many, many, many pictures as I go.

I feel like drum brakes were pretty SOP for a long time then they stopped putting them on cars and people forgot the historical knowledge of how drum brakes work. I’ve had enough drum brake cars that I’ve figured it out a long time ago.

I agree - I think that’s why there isn’t a lot of literature on the subject because it’s just how it is (and they’re all more or less the same), but as they become less common, people aren’t able to figure it out.

I grew up with drum brakes on all 4 corners, so it’s all pretty standard for me. But, as lone_liberal has pointed out, I was taught to di sassemble one side at a time so the other could be used as a reference. The trick was getting them adj usted properly so the car didn’t pull to one side.

Everything takes longer and is more diff icult the first time you do it. I remember the first brake job I did on drums. I took about a million pictures to make sure I did everything in the correct order while reassembling. The 3rd time I did it, it took 10 minutes.....

I hate drum brakes with a passion. Maybe it’s my scrawny computer-programmer muscles, but every single time I’ve had to do them, I find the return springs incredibly hard to stretch into the right spots.
The first time I ever did it, I knocked one of the cylinders out, and got air in the lines. Thankfully at the time I lived in a townhouse complex, and a friend who lived in the same complex was able to help me bleed the brakes.
I wish I could find the comic, that describes how to change drum brakes:
1. Buy necessary parts
2. Remove drum, disassemble parts
3. Abandon car in the Autozone parking lot because you can’t get everything put back together.

Isuzu have different drum sizes too 254mm for 4x2 and 295mm for 4x4
wouldn’t be surprised for most companies that there would be different sized rear drums
