Differences in Drum Brakes?

BTW - I just looked at the FSM again and realized that it actually shows you can "lift" the the adjuster lever away from the star wheel by levering a screwdriver against the bottom of the access hole, as opposed to "pushing" it away on the older style. I should have looked more closely the first time.

That would be awesome! I pulled an axle from a 99 to use on my 2001 and was very confused when I compared the rear brakes before reading this thread.
I just did the rear brakes on my ‘02 yesterday and found the same differences than in all of the videos. Thought I was going crazy! I spent about an hour or more trying to find something on the internet that addressed this issue. All done with my brakes now, and now I see this thread! I agree, a video on the ‘01-‘02 brakes would be great!!! If only just to show how the self adjusters function on this set up?

Maybe, the Timmy the Toolman channel can oblige you on this video request. I'm sure we can find a willing lab rat to experiment on.
That would be great!
BTW, while doing my brakes, I did notice a little dark area of semi dry oil around the center of the backing plate once the shoes were off. Kind of similar to what you would normally see on an engine after xx... miles, and has never been cleaned. I don’t know if that’s normal with age, or early signs of needing the bearings/seals replaced? I’m betting on early signs. I guess I could pull the ABS sender and do the axel spin test that you showed in the ABS video. The truck has 167k on it, so I sat up until 3:00 am last night watching your rear axel seal/bearing videos. I think I‘ll be ordering Duanes seal/bearing puller here in the next week or two, and then picking up the HF press when this Pandemic is over. My T4R doesn’t get driven that much right now, so I’ll spread the sudden expense out over the next few months.
Fantastic job on the videos!!! Thank you for all that you do for the 3rd gen T4R community! It’s greatly appreciated!

I always thought there was something a little bit different about how my 02 rear brakes looked compared to 96-00 that I've seen but never paid attention to what the differences were. You might be right about the rear brakes not being self adjusting with the parking brake lever on 01-02. I've tried it several times in the past & it never seemed to really do anything. I could hear the sound of the cable being tensioned but pretty sure I didn't hear the adjusting wheel turn. Because of this I've always adjusted my rear brakes using the adjusting wheel. Now I'm curious to look in closer detail to understand what the mechanisms are that makes the rear brakes on 96-00 self adjusting and 01-02 possibly not.

You brought up a good point about the rear axle. I'm wondering if differences in the rear brakes will still allow everything to directly bolt on or if the rear brakes would have to be converted to the correct model year (for situations where a good condition used rear axle of the same year wasn't available).
Doesn't [MENTION=102606]infamousRNR[/MENTION] have an 02? ;P
Regardless, it would be cool to see a side by side comparison of the rear brakes on his 02 and your 00 & confirm if the 01-02 can be adjusted with the parking brake lever.

Sean has an 02 but he did an e-locker rear axle swap so he has a rear end from an earlier year.
Actually, and I apologize for my ignorance here, but I'm wondering if the axles themselves are interchangeable between earlier and later models. Here is my reason for wondering. The rear differential in my 2001 was whining on deceleration, so I pulled the rear diff and the right side axle from a 1999. (My original right axle had the backing plate completely rusted away). I put them into my 2001 axle housing, but then I got a clicking sound from the rear differential that increases in speed with wheel speed. It occurs when driving and also occurs with the rear wheels in the air and driveshaft disconnected when I spin the tires. So I figured the used rear diff was not good. Sent my original into ZUK and he rebuild it, (awesome customer service by the way). Put the rebuilt diff in, but the clicking is still there! Planning to clean up my original right axle and put it back in today to see if clicking goes away. We'll see.

the brake differences back there are marginal....
when swapping my 1997 axle, I had the full axle drum to drum, we swapped over my 2002 brake components into the 97' ends because they were in much better shape..
the axles are interchangeable - my 2002 has a 1997 REAR END.
I'm sure you're correct. However, I've been doing a little research and it appear that the 01/02 axle shafts are a different part number from the earlier models and use different seals and possibly other components (thought I read the abs ring was different, but can't find that post again now). However, for me the whole point is mute now, since I put my original right axle back in and I'm still getting the clicking from the differential. Very frustrating!

The axles on the 01 and 02 models are definitely different but they will fit into a 1996-2000 rear end no problem. The main difference is the way the axle is shaped where the bearing seats. The 01 and 02 model axles have a curved seat and the bearing for these models has a curved protrusion to mate up with axle. The retainers and ABS tone rings are the same on both axles. I think the bearing case might be a little different as well.

Ha! Sorry, but a year and a half later this struck me as funny.
Yeah! Pretty sad huh?
BTW, haven’t bought either one yet. Still on my someday to do list.
Just registered to add this: The style OP has with the backside tensioner fork is also on the double cab 2003 and 2004 Tacomas. In Tacoma world it is a larger drum brake diameter then the style with tensioners on the front side and is used only on the double cabs to accommodate for the increased weight.
