If I do ever get to see the rear axles out of the newer hiluxs with bearings etc I can let everybody know if it was just my diff that would be a headache or not

Rear end disc brake conversion

Postby slik_master@msn.com on Tue, 19 Jul 2011 8:01 +0000

Hey there

I was searching the web and came across this:
http://www.designfab.com.au/documents/RearDiscBrakeConversionInstructions.pdf

I was wondering if the similarities between the older lux's and the current model rear end would mean that this would fit..?

We have started working on a rear disc conversion again for use on armoured vehicles. I don't believe all of these components will bolt on to the new lux but a lot of the principles are the same. We have now also given up on using a lot of Toyota components on the rear and are sourcing parts from other manufacturers including custom callipers. The parts by themselves always look cheap but it is a big, expensive job which requires engineering for street use. The upgrade we are working on will only be available for vehicles not equipped with ESC. Still along way from completion and I'm not sure if it will be available in AUS yet due to the costs but it is possible.

I can tell you that Buddy has had nothing but dramas fitting them onto my lux it has been the cause of almost every set back. here is the short list of issues, but they are on now just need the new handbrake cable.

Master cylinder not keeping enough pressure to compress the calipers (took 3 pumps to get pressure then nothing again). I think it has something to do with the bleeder valve.
Brackets to mount them to the diff (part of the reason for going to a custom housing)
Brackets for the ABS (the other reason for going to a custom housing)
custom handbrake cable
custom brake lines

Parr....couldnt you just have goten a Prado120 rear axle and used the that? Same as the hilux centre, and the just weld the 4 link mounts to it?

You'd then use a prado 120 brake booster.

Could be done to all other hilux's....by a prado120 rear diff housing....swap your axles and centre over. then cut off the mounts and Leaf spring perches on it to suit....in a nutshell. :roll:

Rear Brake Upgrade

Postby mow44u on Mon, 27 Feb 2012 5:34 +0000

I Found this on the web, its for the previous generation Hilux so im not sure if it will work on ours:
Some interesting idea's Check out the link:

http://www.designfab.com.au/​documents/​RearDiscBrakeConversionInstruct​ions.pdf

Parts Required:
Designfab mounting brackets
Nissan GQ Patrol Rear rotors DBA622 part number 315mm diameter
'88 / 89 L series Subaru calipers part No. ABP3K
They take DB418 pads (mounting bolt spacing 122mm)
80 series Prado master cylinder 80 series front brake lines
Optional: wheel bearings and seal kit (might as well replace it all while it’s apart)

Good Idea to get rid of the crap drums...
What do people think?

Mate ide love to do this along with the prado front upgrade. If theres a way to still work the handbrake with the rear discs then ill be all over it.

Just gotta wait till my muddies run out now so i can buy 17 inch rims and the prado fronts

Speaking of Brakes,

How do you find the RDA sloted front disc's with the EBC Green Stuff Pads? They are considerably cheaper than the DBA 4000 Series im looking at? Iv just put on 285/75r16's and have lost what little breaking I had...

Discs are great cant fault them, when i ordered the pads though auto one decided they would order me a cheaper (same same) pad so to be honest I dont actually know whats in it now haha.

IMO they are better than the standard by a fair amount but my trucks very heavy so I still think they are in no way good enough. If you cant lock your tyres up in the wet (let alone the dry) then your brakes arnt good enough IMO.

So ill be going to prado fronts as soon as these km2's are done unless someone wants to buy 5 of them off me now :lol: :lol:

nearly any rear brake conversion from previous generations will work on the current generation, the diff is the same other then the track keeps increasing. You just have to make sure the new system includes a hand brake, easiest way is the use a conversion that utilises a drum hand brake inside the disk.

Those old subies had the park brake on the front so it may still work. That may be why they've opted for that caliper?

Aren't drum brakes more protected in a light dash of water therefore hold braking power where as disks can lose braking power due to their immediate exposure to dust & water?

And drums are better for loads?

I thought most road trains were governed unless tampered with as per the current case

Just did a search as Im no mechanic.

Remember that both disc and drum brake design has been vastly improved in the last 20 years. In fact, the current rear drum brake systems on today's cars would provide better stopping performance then the front disc setups of the '70s. And today's front disc brakes are truly exceptional in terms of stopping power. Combined with the fact that between 60 and 90 percent of a vehicle's stopping power comes from the front wheels, it's clear that a well-designed, modern drum brake is all that's required for most rear wheel brake duty.
