Fracturing front disc

[threedogs]

Mine needs an upgrade I'll talk to someone in the know next week ,to see what they say.
Save these rotors an machine so no down time, next pad change

Different material combinations give different performance also different brand combinations
It`s all experimentation,I have allways run genuine disc`s and Bendix pads.
Heat is your enemy but it can be used to your advantage if you know what temps you run at, then find a pad ,disc combo to suit.
This is all race teck, but with an infra red thermometer you can get some idea of where your at.

I guess it's all compromise. I recall fitting 'green' Ferodo racing linings to a Triumph motorcycle twin leader front brake. Fantastic braking performance once hot, but useless when cold. Finding something which provides good all round performance is more difficult. I have an infrared thermometer but not the knowhow to use it's results. Can you but pads for specific temperature ranges?

When you know your temp range and the type of disc your running, IE type of material the disc is made from it`s just a matter of contacting a pad maker and talk to them. There are a lot more material compounds than just the commercial ones. Bendix head office is in Ballarat and you can talk to their Technical dept

OK, a dumb question............... how best to measure the temp of the discs? They are not exactly accessible to point the thermometer at, & removing a wheel to do so is not very practical.

I replaced the rears with rda rotors and Bendix 4x4 pads, about 10000 km ago and so far very happy.

Cuppa are you still running split rims I can`t remember.
Could be difficult unless your running alloys or sunraisers
Possibly borrow a couple of wheels,but then there is the problem of different heat dissipation
It`s not a race car so 20 Deg is not going to make that much difference.

Have the new Black Trak ROH steelies on now - didn't think of that, guess I can aim through the holes.

Done deal mate
There are a couple of pad manufacturers in Australia so an e mail or two and see what transpires
All have tech dept.

Could those who have changed from OE rotors & pads to aftermarket items comment on whether their braking performance improved & if so how & in what conditions.

Although the brakes on my heavy Patrol are adequate, they are certainly not confidence inspiring if needing to stop quickly from speed, & I have wondered if just changing rotors & pads on the front might give some worthwhile improvement.

Cuppa

I feel the same,i often travel big km and always heading north where it is hot most days with my gq,and at times I have had to hit the brakes I wish they could stop a little better.I'll look at the calipers too I thinks.

Guys I just noticed the front disc are starting to fracture.So looks like i'll be doing brakes next.So as there's a few sorts do I stick with the old style or go for drilled and grooved discs.Why do they fracture?
couldn't find no answers.

I had similar experience, GQ front discs have small cracks. I guess reason would be heavy braking. Gonna replace both discs with OEM discs.
