Discs for brembos
 
hi guys

so whats the benefit of having drilled discs or G discs over smooth discs.

I am talking for brembo calipers

you hear some say drilled are the best thing since sliced bread others say do use them etc

I know pads are also key to a good system

I would be interested to hear what people have on there cars and why !!!

Drilled are not a disc I would buy really as they can crack around the holes,the dimpled circles the performance friction disc use on their disc are different though and do not go straight through the disc material and have been proved on track but their disc material they use are quality and that is the key...thats why you pay the extra doe for them.The idea behind grooves and dimples is to help gases escape and keep the pad surface cleaner, you can get solid surface disc that work but in my opinion it all comes down to the quality of material used in the make up of a disc in the first place.SJ.

As Sj said, it's down to the disc material; Brembo discs are high carbon, and their drilled discs don't suffer. Low quality drilled discs will suffer if abused. Dimples and slots avoid adding weak points, compared with drilling. There have been plenty of supercars with drilled oem over the years, so drilled are fine as long as the steel is high quality.
If you're not tracking it, it's sales bs anyway

Brembo ALSO continue to make cast alloy calipers, into which a turned thread accepts a steel bolt. The result is often galvanic corrosion and the bolts then strip out the soft alloy threads on removal, necessitaing the entire removal of the caliper and a thread repair. VOR while it's done. NOT something most folk could attempt.

Brembo know this...but do they fit stainless inserts now, from new, to avoid it?
Nope.:mad:
Have they altered the design to stop it happening? Nope.:mad:

It's all about £££, not service or performance.

Brembo themselves say:
Both Brembo Xtra and Brembo Max discs are excellent solutions for those who desire a sporty driving experience, without sacrificing the comfort and durability of the brake discs and pads. Differences are mainly aesthetic and pragmatic. Brembo Xtra discs are more likely to be the best fit for those focusing on the aesthetic appeal, since drilled discs are synonymous with sport for many enthusiasts.

Brembo Max discs, on the other hand, are a better fit for those focused on substance, since the slots, besides being more resistant to cracking - though only in extreme conditions, such as competitions - are also a valid tool when evaluating whether it's time to replace the disc. There's practically no difference in performance, especially for the level of sports driving that applies to the road rather than the racetrack.

And if Brembo say it...it must be true, eh?

LOL

​​​​​​Do you disagree? They basically said the drilled look better but the slotted work just as well & are less likely to crack.

alcazar 12 March 2018 02:11 PM
Who am I to disagree?

I'm simply pointing out that brembo "quality" might just be as big a myth as MoMo or Recaro quality...much hype, not much substance.:rolleyes:

I would certainly NOT pay extra for Brembo discs.

so what discs do people use then ???

I'm running AP brake disc now as I am on their 6 pots at the front...but came from PF 2 piece disc on my gold Brembo's which were superb...and when upgrade time comes for my AP disc i will be getting some PF disc for my AP 6pot calipers:thumb:.SJ.

nikon-man 13 March 2018 08:14 PM
so whats the benefit of 2 piece discs ??

jazzyjembreaze 13 March 2018 08:18 PM
On a high end disk , your replacing just that ( the rotor) & not the bell. Thus it’s a cost saving exercise

Common sense or not,some members don't have much experience with them thats why they ask the questions....so I find its best to elaborate on a reply so they completely understand the benefits of the upgrade.SJ.
