Brakes on the Toyota 8" axle: my nemesis. So here is what I have. Toyota 4runner axle. An 8" and as I now regret, ABS equipped one. Machined the axles to fit a saab 900 rotor in 4x4.5. Caliper wise, i tried fitting volvo 240 rears but the bottom inlet for hydraulics kinda sucks for clearance. I then acquired a bracket that mounts Toyota calipers but the saab rotor is 280mm and the toyota is ~300 so the rotor i have is too small, but the alignment is perfect.

The old stud holes are a little concerning, but VWMS hubs were severely scalloped, so probably not so much a big deal.

It's probably still stronger than the wheel that attaches to it.]]> Pete Construction Zone Mon, 04 Jul 2016 19:13:31 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112686#msg-112686 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112686#msg-112686

I find this picture terrifying. Those may be giant strong studs, but there is only like an 1/8th of an inch of material around them on that axle, and the old stud holes with the little grooves around the edge are pretty much perfectly pre-made crack-starters. There is WAY more meat holding the wheels on a bicycle.

Is the diameter of the axle tube way fatter near the brake mounting area cause of the abs ring? It doesn't look that way from the pics you posted but kinda hard to tell.

Yeah this mystery lump! I haven't a clue what it is...and i hain't driving out to some junkyard to see it.. he should just lift the phone click clink click and post it here.

Here ya go. I designed the bracket as a two piece deal so that if down the road you decide to put a different caliper on it you hopefully don't need to redo the whole thing. Also the two parts of the bracket are currently being held together with m8 bolts. They are holding but i have been meaning to get something bigger in there... or just weld it.

The alignment needs a little work but its not bad. Im using standard volvo 240 rear rotors.

Beautiful. Simple. Lots of clearance caliper to wheel...something some geniuses think is unimportant...]]> john vanlandingham Construction Zone Fri, 17 Jun 2016 01:07:53 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112453#msg-112453 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112453#msg-112453

Is the hole on the bottom in the 240 caliper typical? See above photo

As far as I know yes. I made 240 calipers work on my car. The hole/brake line clearance is a little snug but it works without issue. I am using volvo 240 rear rotors so if you are using something of smaller diameter then yes it may pose a clearance issue.

If you want I can send you pics of my bracket setup if your willing to wait a few days.

Part of the reason why I chose the axle lengths I did is that I can use a 60" width centered-pinion axle on one side, 58" centered-pinion on the other, both very very common circle-track bits. Then I had to go and run a goofy bolt pattern just so I could keep using all the bazillion wheels I have...]]> Pete Construction Zone Thu, 16 Jun 2016 11:42:03 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112424#msg-112424 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112424#msg-112424

Close, and the Wilwood caliper hangers are threaded something like 7/16-14, the 10mmx1.5 throughbolts to hang the VW calipers are a slightly loosey-goosey fit.

I don't think throwing part numbers and stuff around would help. When I had my axles made, I told the guy that the only hard dimensions I had were 59" flange-flange width (+1 over RX-7) and 1" driveshaft offset to left, I didn't make a housing yet and I didnt make the brake setup yet so make the axle flange to bearing flange distance "whatever" and I'd figure it out from there. And the Volvo rotors have a HUGE center hole, I had my boss whip up a pair of locators/spacer things of the right ID, right OD, and right thickness.

So basically I decided to use certain parts because they were common/cheap/suitable without any concern for fitment, and somehow magically everything worked. This happens exactly never, probability of infinity minus one to one.

All the piccies are on my tablet, which can't connect to Photobucket without getting a malware-gasm.

Oh OK...I'm trying to get him to understand we choose easy to find stuff as close to corrct as possible for the wear parts..Discs and calipers are wear parts....adaptor mount, bolt-on or zap on aren't wear parts..So we make effort in the weird diddly thing so that the consumables are "open the box and stand back and frisbee them on"
Alex has said there's some "thing" for the ABS sensor on the axle he has..much discussion and i can't get clear idea.. I said kill it with fire..or a grinder...
As for a big center hole the gawddam Saab 99/900 rear rotor (and front up to '74--yeah same disc front and rear from '69 to 74) has a GIGANTOR hole in the middle and a fairly deep hat..Toiletta Sumitomo and Superlite Willwood clear and are below the hat surface....
I'm thinking 90/900 disc, and Volvo 240 caliper, mount it up and see where things sit relative to fixed junk and make as simple a mount as possible: flat main plate and spacers to in-out distance.]]> john vanlandingham Construction Zone Wed, 15 Jun 2016 23:46:53 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112419#msg-112419 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112419#msg-112419 Gravity Fed Construction Zone Wed, 15 Jun 2016 22:18:07 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112416#msg-112416 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112416#msg-112416

I found out by accident that Wilwood (Superlite?) brackets have the same 3.5" bolt spacing as the VW units. And it shocked me to learn that the combination of Volvo-Mitsubishi brake rotor, VW caliper, and circle track bracket fit exactly the right depth if I was willing to run a 1"+ caliper spacer.

I'm not, so i just did this:



Drilled through and now the brackets are belt and suspenders welded and through-bolted. Can't use standard 1" long 1/2-20 T-bolts due to the added thickness, but that is what angle crinders and longer bolts are for. Now I just gotta get some 1.25" diameter bar so I can weld the ends onto the rearend. But DAMN anything precise enough is super, super expensive...]]> Pete Construction Zone Wed, 15 Jun 2016 20:00:32 -0500 https://www.rallyanarchy.com/phorum/read.php?5,112408,112411#msg-112411 Re: Brakes on the Toyota 8" axle: my nemesis. https://www.rallyanarchy.com/phorum/read.php?5,112408,112411#msg-112411
