SLOTTED and DIMPLED DRILLED ROTORS

[threedogs]

Hi all would like some comments on the Slotted and dimple drilled{counter sunk} rotors. Is there any advantage over just the slotted. Don't want the drilled for obvious reasons. If anyone has them fitted some feed back would be great.

I've got some on my Mazda and so far so good, just like any slotted rotors they are noisy under heavy breaking. Plus coz they are dimpled and not drilled they don't crack like the cross drilled units

Thanks mate I heard some cracked just wasn't sure which ones,
I would think combined with a good pad, braking would be greatly enhanced

I fitted slotted and drilled to our Ford wagon and geeze what a step up.. Went from average to awesome.
So if they are slotted and dimpled then that would be the best option. With George on the drilled one's cracking out as they compact mud and junk in, and when it expands it cracks the rotor..
And yes, a good set of pads makes a big difference to..

Thanks Kallen any particular brand of pad ??
Bendix seem like an OE replacement
Found a mob that sells Brembo pads I'll use them I think

Pretty sure they were rda rotors and bendix pads. So far can't fault them..

I had slotted rotors on my GQ, I will never be putting anything like that on a 4wd that sees a lot of mud like it did. They always filled up with crud and the only way to clean them properly was to remove wheels. When they clogged the braking certainly was hampered.

They do improve braking, this is for sure but if you see a lot of mud in your travels I wouldn't bother.

Thanks NN any recommendations of decent pads,
Thinking Brembo have a good name
@ NN these aren't drilled only slotted and counter sunk, how can they clog up?


Being auto it just runs on way too much, even driving as a manual to slow it down

Research is your friend in the pad department. People have used the 4.8 pads with good results, basically the softer you go the better the braking at the expense of pad life.

As for the clogging mate, as I said I use to clog slotted rotors ( not drilled or dimpled just slotted) from playing in the mud. It would get into the slots, then would compacted into them from the pad/caliper and that's how it stayed until I cleaned them, usually with the use of a screw driver it would get that hard. If you read what I posted it was from experience and if you saw a lot of mud don't bother.

Slotted/dimpled rotors are good and will improve braking even more so matching a good set of pads to them.

Thanks makes sense big pressures and heat, think another member is going
down the 4.8 road but rotors are only 10mm bigger I think.
