Outer Limits 4x4 Board

Hi Does anyone know of a good brake up grade for a GQ its a 1992 ti, the brakes are pretty average really, any suggestions or mods would be helpful.

Does it have the EFI Twin piston calipers on front and big brakes?
EG does it have 16inch rims?


I remember Darren down Geelong had a brake upgrade with if I remember 6 piston fronts, and 4 rears for $5k with new discs.

Bruce i believe they were being made at a place in heidleberg called TDK Engineering but are no longer in business or from what i have heard

my old boss had them on his and didnt think they stopped better than the standard GU brakes, so he called them up and they said he needed to get the 'better' pads for them at $440 a set and only lasting about 5-10,000 kms, he sold them off refusing to pay for pads

cheers

yea that does sound familiar bout the pads... and I'd have sold em too!

cross drilled and slotted rotors with the newer twin piston fronts and a decent pad

I looked at purchasing front slotted rotors for my 93 Mav ( early single piston brakes) but for the same price of those I was able to purchase standard rotors for all four wheels. ( same brand )

Fitted new pads and as they haven't bedded in I am yet to see how much of an improvement they are. ( at least they have stopped squealing)

Slotted, twin pistons, perhaps even GU larger brakes but for everyday DD where do you stop.
( pun not included but will claim it )

Personally I would have gone the slotted for fronts, but you can have std discs 'slotted'... not sure how much, but it can be done.

The difference from the single to twin piston is huge. Best upgrade you can do.

I did inquire about slotted and of all the people canvassed I received various opinions. In the end available funds ruled the day.


Now what do you do with the old rotors. Chuck em...good for something.

Well got 16'' wheels 2 spot calipers I might try slotted/drilled rotors, see if that stops any better, I am trying to stop that fading feeling.

based on that then the yeah go the slototed and cross drilled, also beed the system out and out fresh fluid though, you alsom may have a soft pad, get a heavyduty standard braking pad, soft pads may feel good on the firt brake but fade out, to hard will be crap until they get hot, also for a firmer feel try putting braided lines on and check your master cylinder, may need an overhaul or replaceing

I went to get quote on drilled the other week, just while there... the bloke wouldnt sell me drilled. said they can expand and crack offroad if you do the hot brakes/cold water gig and the holes are the weak point.. he said slotted are all you require...

I am just putting a GU front in my GQ. Wish it was out of a 4.8 though, there supposed to have the best patrol brakes except for aftermarket.

GQ EFI bolt on, but you will need caliper, disk and pads. Might as well get braided lines.

The upgraded brakes that On Track had where supposed to be awseome. Could lock up a 35 all day.

Im lookin for some braided lines for mine.. apparently they make a shit load of difference too...

How did you go with tires for ya mate?

Nothing yet

We have been using a particular pad for the brake upgrade which works well with the slotted DBA rotors [better material, last longer] and we have also recently upgraded our pads as an extra option using a material that is the same as what we use in our AP brake upgrades for VE commodore etc as well, those pads are dearer, but bite much better on the rotor, and dont destroy the rotor, or look like the front wheels of a hwy patrol car every week with black dust.

We get 50-80,000km out of these on the AP packages, and around 3 sets to one set of rotors.

I run 365mm rotors with 6 pot APs on the front of my every day car, and 365mm rear rotors with 4 pot Ap's on the rear.

My 80 cruser I run DBA slotted fronts and rears, and the upgraded pads to work with the heavy tourer, on 37's.

The std brake upgrade for gq/gu patrol [and 80/105/100 cruier/120 prado etc etc] is $749 for the 4 DBA rotors and front and rear pads.

Add $300 for the upgraded pads.

Add $40 for high temp racing brake fluid also. [changing fluid can make a difference, especially if your current fluid has any moisture in it]

TNT to your door on the eastern seaboard and Adelaide is normally under $30.

Braided lines are normaly $105 ea and improve pedal feel and brake pedal pressure required to stop is reduced when all the pedal effort goes into moving the pads, not expanding the hoses.

The reason the other muli piston calipers didnt work was because you have to go larger dia to get better braking performance generally, and 350mm would be the minimum you would want for the money to do so, which also means 18" wheels.

A better cheaper upgrade would be adapting cruiser front 4 pots onto patrol, but I havent looked at how easy that would be as yet.

Hope that clears it up

yes and no, and it depends on what kind of work you do with your 4b, I have also heard of small rocks hetting lodged in and cutting grooves into pads

either way its very hard to answer a generic question whan people fail to add all the variables

yep true.
I just thought discs would be strong enough thats all to go thru most situations...
eg, where does it end? Yes icy river would cause issues, but what about steep hill, lots o braking, then into a pile of snow before lettin them cool, (drilled I mean)..

Bruce, at least you know how Darren's car gets treated and his customers.

He is very gentle on machinery, just like me...

Drilled = less weight rotating designed for track and unsprung weight reduction.

Slotted is to let gas escape from pads when they get hot.

Dont get the 2 confused.

Never seen a slotted rotor jam enough stuff to damage a pad.

The slots will need cleaning occasionally, but just a service item to be aware of.

True, I still have picture of Rolys face sittin in the Troopys passengers seat as he embarked back down some bitchy steep hill to recover little roly...

This was out back of woods one night as Darren grabbed high second or third, Im not sure the granny handle on the pillar survived... I would have bailed out..

i put 4.8 diff & brakes on my gq and going to put the old front single piston ones on the rear put man the 4.8s made a huge diffrence buy them self
