Making a moveable object solid = bypass. It will only brake better if the conditions you set it at remain constant. As the nose of the vehicle dives under heavy braking the bias valve transfer more fluid and pressure to the front wheels as they have more weight on them so more traction available for braking - due to the load shifting forwards.

When you fix the bias arm you prevent this from happening. Under heavy braking constant pressure is applied and does not differentiate. The outcome is that the constant force to the rear brakes when the nose dips under heavy load will be a lock up of rear wheels whilst the front brakes which could use more pressure, is not supplied it - probably feels like it is braking better but in actual fact it is not.

Bias valve is not there just for weight adjustment of brakes under normal braking - but also heavy braking braking events where the weight always moves forward requiring more force on the front wheels than the back. Modify it at your own peril is all I am saying - watch the road crash investigations, the mod will be picked up and you may be asked how you arrived at your "made it safer" conclusion.....

The "bias valve" or lspv only controls flow to the rear. Under heavy braking with brake pedal undermax force you no longer have flow just max pressure. Max pressure from master cylinder still equals max pressure up the arse of the front brake cylinders. Adjusting the Lspv will have extremely minimal effect on your front brakes under heavy beaking.
If you read the link you posted a Disc/drum setup only supplys so much to the rear.

07luxyTD - that's true - if the rears are not doing the correct amount of work even with max pressure to the front it will make them "feel" as if they are not working that well as more braking effort is required from the front. When the arm is adjusted to a slightly more loaded position the brakes will "feel" like they are working better - this is why brakes feel like crap when you do a lift - the arm distance has increased bypassing pressure to the rear brakes.

Note that the front brakes are connected to the rear brakes by the backup line - if you open the front brakes bleed the LSPV as well as air could be in the backup line causing a spongy pedal feeling.

The National Vehicle Standard states that fitting or modifying brake balance and pressure limiting devices requires engineering approval. You can adjust the arm but cant replace the mounting point of the arm with out an engineer signing off on it.

After reading all the above ,ms till a bit confused
I have a 2010'sr5 and want to fit the prado calipers to it
If I get the set up from a 120 series prado, can I not use the standard 16 inch prado gxl wheels as well, I keep reading that if u use the prado brakes u need the 17 inch, if the prado has 16inch gxl wheels, Wu could I not use them

Because the 120 Prado uses 17 inch wheels, the 95 Prado uses 16s and they just clear 2010 hilux brakes

Thanks ben, was thinking that after I wrote the post
Am I better going the 95 prado brakes then ?
Don't really want 17" wheels

Not sure if they will go on, probably better off with a pad and maybe a rotor upgrade on the standard brakes.I have no idea what works well mine is still on the factory gear, maybe others have more experience.

Hey guys thought id add a quick question. How much difference s there in performance between a vsc brake and a prado brake. I have the normal brakes now but can get vsc brakes easier than prado brakes and slightly cheaper and i can fit 16s so cheaper tires. but i do plan on 35s when my lux is no longer my daily so braking performance is important.

I have just finnished putting vsc brakes on my 09 hilux. The calipers cost $125 each of smart parts in vic. Pads were $80 from qfm, hpx model. Rotors were $300 a pair from rda ebc off ebay.

I trial fitted my 16inch rims on a prado and they just hit the caliper by like 3mm. So with the prado option ruled out i decided to trial the vsc hilux/fj cruiser/ us 4runner brakes. The caliper cleared my 16s by approx 8-10mm.

Hopefully this helps others that are wanting to stick with 16inch wheels (note that not all 16s will clear these calipers)

Here are some photos of standard vs vsc hilux brakes (still smaller than prado)

I have Speedy 16'' (Prado look-a-like wheels) and on speedies website they state they fit prado. If I test my wheel on a 120 Prado and it fits, does this mean I will have no issues with the Prado brakes on the Hilux?

This is will save me the money and effort fitting the brakes just to see if they clear he brakes or not.

Any thoughts?

So I tried fitting my wheel on a 120 Prado. It only started to rub on the caliper about 5-8mm from the whee being on the hub completely. The question I have is - the Prado has a 30mm offset and Hilux 45mm. Does this mean when fitted on the Hilux the wheel will be sitting 15mm closer or away from the caliper? If it is further away - these rims may fit? From my limited understanding with the offsets, the extra 15mm positive offset will push the wheel closer to the caliper which will make my rubbing worse...

With positive offset, the higher the number, the closer to the centre of the car, so +45 will be further in than +30.

The 120 Landcruiser brakes will sit identically on a Hilux as you use the rotor and caliper, so if the wheel rubs on a 120 it'll rub on a Hilux with the 120 or 150 brakes (only difference 120-150 afaik is rotor thickness and a bit more width in the caliper for the thicker rotor. I don't think the Hilux and 120 are any different in offset if they have the same size wheels fitted, ie 17x17.5 are the same offset for 120/150 or Hilux.

Hey guys.
Just found these guys on trade me in nz. But they are based in Australia.
For a brand new set a aftermarket calipers, disks and pads is 375.00 plus shipping.

https://www.onlineautoparts.com.au/Welcome.action

Not a bad price.

So I'm giving this conversation some serious thought as iv warped my front rotors twice in 18 months on my 06 v6 double cab. 165000km on the clock. I do a lot of heavy towing, diggers and other machinery.
Will bigger rotors disapate heat better?
I have 2015 sr5 17s on already so fitting them won't be a issue.

How'd you get that price? I'm on their site and just for the calipers alone they're $307.35 and haven't even begun to add discs and pads.
