DBA slotted rotors

[rOd]

Has anyone got these fitted to their rig?

What are they like?

Is it worth it?

The reason I ask, is because I plan to change my front rotors when the air locker goes in the front. My current rotors have seen happier days.

Cheers,

Rod

Bazzle has them and loves em, they work well and help when you run 35's. Better brakes are always worth it! Just dont go the drilled ones.

Ive heard horror stories about crossdrilled rottors cracking. Whethere or not its true I dont know.

Anyway, Ive got the slotted ones on order and they are setting me back $128 each side. Is this a fair price???

Also, which pads do I use?
Bendix 4wd pads???

fitted my DBA slotted rotors over Christmas. Breaking performance is great now. It is worth it for cost and effort.

[MARKx4]

are you just talking slotted or slotted and cross drilled. I find the cross drilled better. Havent got them on the patrol yet, but put them on my mates and he loved them.

[adam.s]

Cross drilled will vent/cool better, but are more prone to cracking.

Everyone's heard of someone else who has had it happen to them, but I know plenty of people with crossdrilled rotors that havnt cracked.

DBA stuff is quality.

Have aset of slotted DBA's on the front of my patrol for the last 12 months. No dramas at all. Very happy with them!!

[MARKx4]

You dont get problems with the slotted ones, the cross drilled ones, you here they do creak. But i never had that problem when i had them on my commodore. And it had just over 550bhp. People who crack them are people who dont have the correct brake set up on there cars.

I think the prob with cross drilled ones is more apparent when you go offroad especially in mud etc.

Got slotted ones on the front of mine and are good. Dont use bendex 4wd pads (supercheap) as they are too hard. They may last a while but dont perform well and seem to have a lot of dust.

I have seen cross drilled rotors with cracks.
Common'ish on R32 GT-R's that have been driven hard with cross drilled rotors. But hey they are a race car more or less and often driven that way, have my doubts it would be as much issue on a 4wd.

Guys,

If I just make holes in the genuine Nissan discs....what do you think?! Are the drilled ones different in terms of metal composition?! I really don't know...

Any ideas?

Thanks, Gabi

DONT DO IT!. The drilled ones are designed that way. (Holes cast in) They will fall apart if you modify your own. Just not worth the risk.

Ive researched this extensivelly in the past. Its not the way to go. IMO

The DBA slotted are quite good value and are made from a select nodular cast iron.

Drilled disks are not necessary only slots are required for an improvement.

All the info is in the DBA forum listed below somewhere.

Drilled rotors do not work off road, fill with mud.
Slotted are good as they "wipe" the pad and also allow plasma phase gasses to escape etc.
You will find most real high performance stuff is now only slotted even though drilled (cast holes) are around as people want them (bling?)

So which pads do I use???

And is $128 per side (front) reasonable???

Thanks for all the responses.

While on the topic, what brand/model of pads do people use.

My GU seems to have pretty spongy brakes (as has been mentioned in other posts). Apart from slotted rotors, what have other people done to improve this "feature" of the nissan braking system?

[bazzle]

Bendix 4x4 pads work OK and from cold. Metal kings work better at high speed but you will run up someones bum when cold.

$128 OK

I've used the bendix 4wd pads before on brand new machined disks and they were falling out, dead after 10,000klms.

Seemed a bit rough on the disks too.

Snap... I did exactly the same. Thought it was my heavy foot on the picks

Nope, I think Frank had the same happen to him too, almost identical amount of klms. I figured they should last a shit load longer than that

I found a decrease in brake performance when I put bendex 4wd pads on the rear only of my truck.

Will replace again when I get my rear disks.

I know of someone else who took em off the rig immediately after putting em in and testing cause they did not work at all. Put different brand in and hey presto brakes again. IMO they are just too hard.

I would rather replace pads a little more regularly and have good brake performance.

I got my front pads (which seem very good) from the place I got my rotors but I am unsure of brand. I will try and find out for you.

Just use the Metal Kings as Bazzle suggests, they're great.....but only when warmed up a little!!!!

use lucas pads there a bit dusty but they pull up really good, dont go bendex pads i,ve seen about 4 of my mates cars with big grooves in the rotors from theem, they used to be good but as soon as they went aspestos free they fucked something up.

[rOd]

Thanks for all the feedback guys.

What I might do, since my current pads are still 2/3 thick (Bendix 4wd), Ill try them first and if theyre crap change to something else. Metal king maybe.

Having said that, Ive also heard that metal king pads wearout the rotors pretty fast.

Have been told the same thing. I was told (and I'm not sure if I really trust the source) that to get good performance on big trucks like these you need to use a pad with high copper/brass content instead of mild steel (like Metal Kings) as they have great friction without a lot of rotor damage. I guess it's a "try it and see" jobbie ...

[Shorty40]

Just replaced the front pads in my GQ today.

Brand .... OEM ? I think that is the brand, as they are not Nissan parts.

I will see how they go
