Brake upgrade??

[Coldcomfort]

I have bought a set of braided brake lines from Marks adaptors and am considering the disks front and rear.

The disks here are slotted. I've heard that slotted/drilled disks are no good for off roading? Has anyone bought these? Whats your impression.

Cheers all.

From what I've heard, the holes in drilled discs may fill with mud, but slotted are not as much of a problem?

I can't comment on a rotor or pad upgrade, but I can certainly recommend the hydraulic brake booster from Mark's.
I did this on my 2004 GU III about 12 months ago and the improvement was nothing short of amazing.
Still with factory rotors and pads, stopping is now not a nerve wracking experience.

I fit uprated lines (braided rear and load-leveller, the fronts just HD cos they can't be braid as it doesn't have the flex to work with the factory steering geometry)

I can't see any advantage to slotted rotors unless you're circuit racing the thing, in which case we want to see vids :)

I have a set of these ready to go. The front don't seem to be any different to the others.

My disks are the original from new. They still work OK but I figured that I might as well replace them at the same time as the brake lines. My brakes have become spongy over the last year or two.

Brake master cylinder has been replaced but no difference. There are no fluid leaks.

If I get these new disks I'llget a brake specialist to install them and service the calipers. Hopefully this will cure the spongy brakes.

You will notice a difference with the braided lines. The hoses expand under load so you lose that pressure reserve. The braided lines hooked up to factory single pat disks and factory pads got me thru the brake test for the GVM upgrade - the brakes were smoking hot after 40 emerg stops, but I suspect the lines were the clincher. I agree, the braided lines on the front will be fine and wont restrict movement.

Regards the potential for mud build up, yes I guess its true however the disks get hot and the mud will eventually fall out i would think or be flung out when wet under rotation. I would not be concerned about these features - they obviously are there due to them being some benefit, unless you subscribe to a marketing theory that they are just dressing as a point of difference.
