Upgrade from factory brakes

[flavell]

Hey every one just wondering if anyone can recommend better brakes as the factory brakes just aren't doing me any justice

[fraz91]

have a look here if you just want to upgrade the factory discs and pads. There are a few people who have done the swap to 120 Prado front discs, but I personally wouldn't recommend it unless you get the whole thing engineered.

if your wanting to run bigger tyres e.g. 33" would be a good idea to upgrade them

Cheers for that guys I've emailed Brendan from ultimate and asked him for a quote

you shouldnt need engineering as it came out as standard fitment on TRD Hilux's.

Thanks maxx I'll look into that too

For record, the brake boosters and master cylinders were the same as standard hilux aswell.

It was just the caliper/rotor/pads/two hard brake tubes that were different.

Quick question Max, if its only the parts listed is it actually possible to buy the parts required from Toyota or would it still require TRD vin chassis numbers to get TRD Hilux parts as i believe they dint use to sell any TRD parts unless you owned one.?

They are the same as Prado120 parts. And I wouldnt bother gettin them new as they cost an arm and a leg.

Calipers are 120 each from the wreckers. Get a genuine seal kit and replace the seals yourself. very simple.

backing plates are a few bux each, get second hand rotors, machine them and a set of pads.

400 - 500 bux you have better braking. or thereabouts.

genuine caliper will set you back 800 bux each!

As Maxx said no need to engineer. As factory used it in the same model in a different guise as a TRD.plus no modification really required to fit as its a bolt up configuration.

Just like the old days with falcons and commodores. The higher level spec cars got LSD disc brake rear ends and you could fit to your lower end spec car along with a master cylinder which was a 1inch not the original 15/16 size, just bolt them in and off you go.

I actually did this brake upgrade in December. I went to a local 4x4 wrecker and they had a low mileage 120series. Got the lot for $580 and fitted myself.
I got the calipers , short brake pipes, rotors and a set on genuine (pink) pads with 10% wear on them and the backing plates.

The swap over was easy and took about an hour. The hardest part was locating the correct socket to fit the driveshaft nuts.
I was never inspired by the original stopping power and when I checked the brake performance and proportioning on the safety stop (platetronic) unit at work before and after I saw a difference.

It also helps to adjust the LSPV on the rear diff to get a bit better proportioning. I did a before and after and made about 10 to 12% difference

Might be a silly question, but why would you need to change the master cylinder if you are gonna swap out the drums for disc..? Dont drums require more fluid in the first instance and replacing the master cylinder for a larger unit would mean that the replaced calipers are getting more fluid than they need for the same amount of travel of the pedal..? Also what is the residual valve on the master cylinder..? Be gentle, im only learning...

[slik_master@msn.com]

Had it all backwards.. Here is a site that was helpful. http://www.mpbrakes.com/technical-suppo ... inders.cfm

Modern callipers require more fluid than drums as the pads are further away from the rotor to reduce brake drag and improve economy. This means there is more fluid displacement to activate the brake and is why vehicles fitted with 4 wheel disc brakes have a fast flow valve in the master cylinder. If you go Prado rear brakes, you should also look at the Prado brake master cylinder.

What Fraz said about the brakes is also true whether it is common practice or not. Everything is based off your exact vehicle model and any substitution for non standard parts has to be assessed. It's exactly the same as how earlier Hiluxs cannot tow the same amount as later ones even though the chassis and suspension components are identical. Common sense does prevail though and most engineer's would pass the brake upgrade straight away as long as everything has been fitted properly.

Brakes
Brake systems must not be modified such that the brake performance is reduced or that the risk of failure of the brake
system is increased. Brake discs or drums must not be machined beyond the reconditioning limits set down by the
manufacturer. When brakes are upgraded using components or systems which were not standard options for the
vehicle, an engineering certificate is necessary to attest to the adequacy of the new system, eg: hydraulic fluid sufficiency, balanced braking on all wheels, brake pedal pressure limitations and braking performance

If I was doing the Prado upgrade; I personally wouldn't just be using second hand parts. The callipers would be ok with a service and inspection, but I would also be upgrading the rotors and pads to get the most benefit. There are heaps of performance parts available for the Prado or FJ Cruiser (Depending on what size rotors you want to run) that reusing second hand originals doesn't make sense IMO. That way you would be running brakes which are larger and have better pad bite, fade distance and cooling properties. Braided brake lines also make a huge difference on the Hilux as part of a total upgrade.

So really all you need is the second hand callipers (as original ones are far to expensive) And get a set of slotted rotors from auto one (120 prado obviously) and some decent pads to suit.

If you have upgraded your standard lines to braided ones can you reuse them if you do the prado 120 upgrade? ie are they the same lines/fittings on the callipers? Ide want to think they are.

So really get the second hand callipers are all you need to find??

And 17" rims mate.

Ah yes well played Mick, I hear they can fit with certain types/offsets of 16's though. Not a fan of grinding my braking gear so if there are none looks like my next set will be 17's.

[helmut79]

308/70x17 = 34"...............

Haha i wont be able to fit those. I am just wondering the widest km2 i can go though.

I havent done the body mount chop but i want a wider 33 than the 10.5 im running now when i change to 17's to get these brakes done once this set has had it ill be buying some.

they come in 265/70, 285/70, 285/75, 305/65 and 305/70 amongst others but i have no clue which will be closest to 33 inch and how wide i can go and rim offset etc.

Anyway not to hijack the thread but ill be looking into those in the next few months

[Noidea]

Ive been doing a bit of research all morning on rims and tyres to suit a prado brake upgrade and faaaaaark me 17 inch tyres are expensive. Im already running 33/10.5/15 KM2's and to get the same tyre in a 17 inch version is like an extra 100 and something odd buks. The cheapest I could find is $430 a tyre

Has anyone looked into getting rims and tyres to suit this upgrade?? Im looking for a 17x8 inch rim with a +10 offset but its all looking very very expensive right now.

I might have to change rubber and get something a little cheaper if thats the price im going to have to pay. Ill have to add a rim onto that price as well. Was looking at some of the allied wheels but im scared to find out the price.

Dont suppose anyone makes a cheap 17 inch steel rim do they lol
