Rotors: Slotted vs. Cross Drilled vs. Standard

Re: Rotors: Slotted vs. Cross Drilled vs. Standard

What are people's thoughts on changing both the rotors and pads in the one upgrade? I have heard that if you can avoid it to only change one or the other at any one time.

I realise new cars come out with both news (obviously).

I hope this isn't too far from the topic thread.

I have also seen DBA has released 4x4 rotors - anyone seen or had any experience with them? Maybe just a marketing ploy, or maybe they aren't new at all, isn't just that I have only just noticed them.

Best results are achieved if both the pad and rotor surfaces are new/refinished so that they have the best chance of 'mating-up' correctly. A failure to do this can cause glazing and will result in reduced performance.

Having said this pads today are being manufactured with metals in them that are designed to assist the bedding in process e.g. Bendix have a titanium stripe. This is much the same a chrome moly rings in racing, they're harsh and cut into the new mating surface almost instantly. Not good for wear though.

For the $60 I'd have my rotors skimmed (or ground if you have slotted/cross drilled) and then fit up the new pads.

Having said this if the rotors are in really good condition or near new (very low grooves / scoring) then you will be fine.

My rig has done 3k now and I'll be changing the pads on the weekend without a skim.

3000km and you are going to change the pads already? I know you mentioned 3 sharp stops on the freeway and the onset of brake fade but what are you doing?

Are you saying you are just going to replace the pads with something less likely to create undue wear or are they really shagged?

Just replacing pads becuase of how poor the std ones perform. Fade is one thing, which I rarely have concern with. It's the vague 'no bite' when you initially hit the pedal that concerns me. All that time lost to wash off speed in the initial stages of braking concerns me that I'll be chasing my tail in the later if an emergency / more brutal stop is required.

I'm expecting std pads to look new.

Hi guys
new to the forum
i want to upgrade the rotors of my 150 Turbo diesel. But here in Haiti, this is impossible and they don't sell Prado in the USA.
Do you think it's possible to switch the actual rotors (dimensions: 338 x 28mm) to 150 V6 or Lexus GX460 (338 x 32mm) ?
Even slotted or and drilled rotors are impossible to find here !
thanks for your help

All this talk about rotors, but has anyone ever upgraded the calipers to like a HSV spec caliper (4 or 6 pot?)

But not on the Prado.

Pfftttt details schmetails...

rorza the front calipers are already 4 pot. For what it is the Prado has decent brakes. I just have to remember what I am driving at any given time...

[rorza Member Find all posts View Profile Close rorza]

yeah, I find that to be a problem I have too mjr. The only reason I ask is because I saw some brake kit used in Dakar cars being sold by some OS company, was about 12k ha! and wondered if anyone has the disposable income to throw on that haha.

I changed the rotors in my 120 for DBA slotted and cross drilled rotors (supply issue, would have been happy with slotted only) and Bendix pads. Improved the braking and was plenty good enough. The other threads have pics. Looking at the DBA site which is a bit of a nightmare the T2 discs look the goods.

I want my pad cover unit thingo painted red or yellow too.....

That would be the Calliper Red makes you go faster so would have a detrimental affect on braking force, so yellow is your only real option

OK, I'm starting a new thread on painting callipers. Is it one "L" or two?
