was travelling down kangaroo valley in my XH over the weekend and got massive amounts of brake fade. was pushing it a bit then had to slow right down so i didnt go over. i've got slotted rotors on the fron would putting a bigger master cylinder and booster in make any difference and what would i get it off or what would i do to prevent this in the future??

Hmmm... brake fade is really a part of the physical world... cooling is essentially the cure, but with slotted and all... Better pads would be the next step. So, maybe Greenstuff or something.

But I would just recommending been easier on the brakes. try and use gears.. ie compression braking. And at the same time, try not to apply, or apply very little brakes, but with increments of no braking in between to allow cooling.
I guess if you take it that seriously, Joe at CMS has 4 spot barkes on the way... and fuzion has 2 pots on his... so bigger brakes are an option...??

Cheers

hmm

slotted rotors are a good start, but useless without decent pads, ditch the shields behind the brake discs, flush your brake fluid out and get some decent stuff in there, etc

Decent brake fluid should definately help, if the stuff you have is getting a bit old.

yeah well i havent changed the fluid as such. just bled the brakes every now and then. but ok i can try that.
next time i've got the wheels off i'll get rid of the shields. and the pads are just standard replacement items.

i dont take it heaps seriously i just like to give it a bit of a go every now and then. and kangaroo valley is a place that i like to do that.

the problem with kangaroo valley is you can only compression brake so much before you have to apply the brakes at a decent rate as the descent gets very steep and you can pick up speed between hairpins rather quickly.

but i'll try those things mentioned and see how i go.

cheers guys

Agreed, first thing I'd be looking at. Old brake fluid will cause fading as it heats up more.

Don't use compression braking to slow down, that's what your brakes are for.

It costs very little to replace a set of pad/rotors, compared to a ger box/clutch.

Basically if you're getting brake fade you need to take it a little easier.

Good luck and smart driving!

if you're having brake fade issues or driving in a way that brake fade can/will occur, compression braking is the best option..... ask any truckie

Appreciate what you are saying, but as any truckie will tell you they run on diesel, and compression plays a much greater role in their engines, and their vehicles are designed for compression braking . Besides that he's driving an XH ute, not a truck, and if he is getting brake fade through Kangaroo Valley because he's giving it a little stick, he needs to drive smarter not harder.

Or he can upgrade his brakes!

If good pads/fluid don't do it. Maybe go the next step with DBA Gold brakes, or if your really keen go to GT brake conversion.

cds70 - point taken... But I always got told to use compression braking if its a continous hill, to aboid brake fade. But I see what you are saying, basically to drive more carefully, and not foot flat through the valley.


Cheers

Ring Joe at Crescent, Get his 4spot upgrade, I highly recommend it. As to DBA Gold, not worth the cash, Had them on the 5.0 pre 4 spotters and they dont rate at all.
