00 drums to discs rear

So ive been stalking the Gen1 forums for a few days now. I'm looking to do a drums to disc conversion. But I can not find qhat I need on the search engines, nor my stalking here. And info, links or a kit reccomendations would be awesome.
Preemptive thanks.

P.s. I'm sure this has been beat to death, I just can't find the old posts.

Someone here (i think) converted using ford calipers, but i dont remember who.

 

Didn't someone also do a Sequoia rear axle swap?
It involved some cutting and welding iirc.

 

This mod has been rolling around in the back of my brain for a year or so. Thanks for the link and info. I was thinking that perhaps the rear setup from a Sequoia might work, but I'll take a near complete kit even if it might be a bit more costly. Less time running around sourcing various parts.

 

I remember seeing a video on this on youtube a while back.

 

Wouldn't the sequoia rotors and caliper hardware from an 00 or 01 just be a bolt on conversion?

 

Do you have a link?

 

no, the backing plate/ caliper bracket pattern is different, and the tundra uses 3 pt abs, where both rear brakes come through a single line, and the sequoia uses 4 pt, so each side gets its own dedicated line.

when i had my sequoia i thought about it, but since i would have had to modify both vehicles it didnt really seem worth it.

 

The Sequoia has rear springs, no leafs. The cutting/welding is for shock mounts and misc brackets. I would assume the spring bucket on the axle would have to get removed too.
A couple pics from my Sequoia.

 

Ok I think this is what I remember. something about the ABS compatibility, and I didn't really care because I leave my ABS disabled anyway.

 

Nope. Sorry

 

You need to do this. You have basically the holy grail of 1st gens, so it would only be fitting of you to get a sequoia axle under there, then show the rest of us unwashed masses how to do it.

 

Having done this conversion myself, there's a little bit more to this than just "bolt on conversion". For rear discs to properly operate you'll likely need to change the master cylinder for a larger bore Sequoia master cylinder. There's an adjustment on the push rod inside of the booster needs to be fine tuned. The calipers you put on are only one piece of the braking system and the rest of the system needs to be able to keep up. My OEM MC was a 13/16" bore, I think some of the ACs have 11/16" bore MCs. Sequoia MC is 15/16" diameter. You might be able to get by on a stock MC, but I'd imagine the pedal travel would be increased and have a "softer" feel.

Overall the conversion isn't too hard to do though, but may require some trial and error. SOS Performance backing plate kit is certainly one way to accomplish this. You can save a little money by sourcing your own Sequoia calipers/ rotors/ pads, which is what I did. I did this swap myself a little over a year ago now.



To eliminate the drum backing plates, you're going to have to either cut them off, or have the axles separated and repressed (a machine shop can do this). If your truck is on the original axle seals and wheel bearings, this might be the time to do those when having the axles repressed.




You'll have to bend/ cut/ re flair your rear brake lines as the stock ones are a little too long, even if you try to use the Stoptech stainless steel lines SOS sells. I had custom 31" stainless steel braided lines made that go from the T on the center of the rear axle to the calipers with banjo fittings. Keep in mind Toyota brake fittings are Metric. You can go to Napa etc. to have new brake lines bent/ flaired, but chances are their brake fittings will be SAE.

The parking brake is a standard drum-in-disc setup that's found on other Toyota vehicles. I sourced my own Sequoia parking brake shoes and pads.




Your ABS sensors (if equipped) will no longer be easily removable. You'll have to pull the axles out about 1/2" if you ever want to pull them. Small price to pay.

 

How was that part of the swap? I wonder if that would help on the 14wa brake swaps.

 

I've thought about that too. The Sequoia master cylinder with the SOS adapter marries right up to our brake booster.

Swapping the master cylinder isn't too bad, obviously bench bleed it first. The M/C I got had extra brake lines and female-to-female fittings so that made connecting it to the existing brake lines a breeze.

The part that is tricky with this is the new adjustable push rod. Completely different than the OEM one. Mine kept locking up my brakes completely until I had it just right. That meant disconnecting the master cylinder from the booster and reconnecting it about half a dozen times.

 

@des2mtn that doesn't sound bad.

 

Great write up - with pics!! I just replaced my rear drums when I did 14WA up front, so I won't be doing this any time soon, but I enjoyed reading and seeing this.

 

Has anyone run these, or know about this kit? If so any feed back, and or links to an install/ conversion video?

That backing plate is the exact same design as mine. The calipers are the same cast number. Everything I said in my previous posts still apply for this kit.

 

SOS Performance has the kit you need. Tom also very helpful for any questions great guy.

 

What's the performance difference like once discs are added to the rear? I know I was not happy with my brakes for a bit -- that is until I properly adjusted the rear drums on my 2000 2WD SR5 Access Cab. Once I did that, the stopping power became impressive and the pedal feel became very solid. Prior to this adjustment, the pedal never really felt firm.

 

Stopping distance is shorter, pads easier to change and no brake adjustments. I also used the stainless steel brake lines.

 

Does the lspv still work? Manual proportioning valve? Ever lock the rears in an emergency?

 

works just like it was made for it. no problems so far and yes i've locked it down. I have the dc i think SOS suggest changing the master cylinder on all others. But not sure. Mine was not changed.

 

Traction control still work? If dc’s have individual abs for each rear like sequoias.

 

yes

 

No they don't. Both the rear wheels are fed by the same brake line. There is a T in the center of the rear axle...

 

There is no reason to swap to discs.

Complete waste of time and effort. Toyota drums work great and the shoes last a very long time. They are also easy to work on.

Tacomas still have drums.
