I upgraded to some drilled and slotted front brakes for my BMW, and some Green Stuff pads, and immediately noticed the brake bite was so much more positive. Brake fade also was cured, and they made a cool sound whilst stopping.
This was great info for me. Because I was just doing some research and wanting to do a upgrade. Brembo vs EBC drill and grove now I know to just get the grove and I'm going with brembo all round due to finding out EBC use a softer material👍🏿
Floating rotors would be one more step up in performance. Usually they're comprised of an aluminum bracket to save wait and a floating perforated stainless steel disc that makes contact with the pads. They actually come stock on a lot of performance oriented motorcycles.
Man I’m new too all this. I have a 06 DTS I’m wanting to put high tier brakes on. What do I look for? What are some brands I should be looking at or staying away from? Ty
I’m just running drilled and slotted on my Accord. But I do have to say, one of my calipers locked up in the rear and I got back home and the pad physically grounded down into metal and even grinding into the rotor creating huge grooves absolutely destroying the rotor but the drilled holes weren’t cracked. So I was impressed to see that. I still run drilled and slotted, might run just slotted on my Corvette now though.
@@misterbulgerI had this happen and I’ve been so curious if your brakes would work better without grease long term. the grease and dirt combo on mine ate through a pretty new pad and rotor. Locked up on me. I’ve seen a ton of videos of people installing brakes and they don’t grease the pad slides….. I grease mine and only had the problem once. not sure
@@zigzag7194my experience from brembo is that their pads dust waaaay too much and the pads didn’t last no where near the amount my ebc pads did. My ebc also dusted very little if at all and stopped just as good as brembo and those weren’t even their track version pads
EBC is a very well known brand you should give them a try. Their pads are great if you go for the more street oriented ones. They stopped as good as brembos without dust going all over your wheel. Now it might differ from car to car but that’s just my experience. I haven’t tried their track oriented ones but i heard they have more dust but stop even better and resist heat more
So I have a 2016 Crosstrek and I had drilled and slotted rotors because I have a camper that I tow with my brakes are squeaking and I don't know what rotors to get now cause I was thinking of getting drilled Brembo rotors
Definitely drilled and slotted and if you’re really driving fast I’d recommend getting a brake upgrade if it doesn’t have them pre installed and if it’s in your budget something like brembos or willwoods that give you good stopping power, sure it might not be a huge noticeable difference to some but even an inch can save you from an accident or worse
Drilled/slotted rotors are mostly for gas to escape not cooling. The ones you called blanks are really called vented rotors which is what does most of the cooling. On performance cars they are directional for this reason
like i said in the vid, off gassing isn’t a big issue with modern pad compounds. all three types of rotors can be vented. all 4 rotors in this video are. most are straight vaned, and some are directional, like the upgrade 2 piece rotors i put on my Z here. yes, vents are primarily responsible for cooling. drilled rotors can have marginally better cooling because of the additional surface area in contact with the vented air in each drilled hole. but you lose out on some material available to absorb the initial heat generated by the pad friction.
You don’t have as much initial bite with a solid rotor versus slotted but with a good pad you can get similar initial bite. The important part is you are less prone to brake fade because solids have more mass in the rotor for both friction and heat dissipation. Slotted rotors do look nice though. Drilled rotors are a joke.
Brake pad offgassing is when brake pads release gases when they reach high temperatures. This happens when the brake system can't transfer heat to the environment, causing the brake pads to break down and the resins that bind them together to outgas. The gas creates a thin layer between the brake pad and the rotor, which acts as a barrier that reduces friction and braking power.
@@ChrysGaines Thank you for reading to me what the book said. You still did not explain to me how gasses can get caught between a spinning rotor and brake pads.
25 year mechanic here, and those are the best ones. I never do slotted or drilled, always both. Any time I have seen just one style on a rotor, they fail prematurely on daily driven and track cars.
So…. Just purchased a jeep off of fb marketplace and mine are drilled and slotted…. Aftermarket?? If so, how can I tell what brand it is , come replacement time?
If you're not a street racer, stay with the original type brakes. Modified discs wear out brake pads faster. You won't be able to win 100% in any case, there is always a minus.
My biggest problem with drilled or slotted brakes is they clog up within a month (through some thorough road driving) sp I find myself drilling the holes again front and back all the time it's a bit easier to clear slotted ones
do you know how long it takes a visible crack to propagate until it’s officially “dangerous”? i personally would just rather not worry about it at all, or get ceramics lol
@@ChrysGaines As long as the crack stays under 5mm you don‘t need to change them. If the crack is 5mm or more the brake disc must be replaced Or as I sad early if the crack goes from one hole to another If the brake disc has a crack in the friction disc edge, it must also be replaced. Official information from my Porsche information system.
ceramics for sure! i used EBC yellows for a while and liked them. currently using carbotech race pads and they do dust up a decent amount - not designed for street use at all tho
False, drilled rotors provide more brake bite. When all that hydraulic pressure is being applied, the edges of the hole scrape into the pad causing more friction and heat. Inturn shorter stopping distance. However, drilled rotors have less metal to hold heat, so engineer's have to design them to be larger for a good thermal ceiling. If your vehicle was designed for solid rotors and you switched to drilled you have reduced your thermal ceiling. In that case just go with slotted for an up grade.
nothing i said is false. you’d be hard pressed to notice any additional bite between slotted/drilled and blanks on the street when compared to changing pad compound. but as you can tell I’ve written them off already due to the literal visible cracks in the drills that came on my car. the thermal ceiling is correct, and yes i recommend slotted or blanks when upgrading the whole system. i like slotted for keeping the pad face uniform and clean.
@@havefun1226 not the big brakes.. I have the base model breaks I just put slotted and drilled rotors but ima have to upgrade to the bbk cuz this ain’t cutting it .. ceramic pads but tbh I think the bbk must make a big difference I see other cars with the bbk stop like nothing
Having slotted drilled rotors on your daily shit box ricer is pointless. They make the difference on heavy duty trucks and rolling tanks like Escalades and expeditions.
Don’t bother getting any drilled or slotted, they all fail and short lived if daily used. Learned the hard way with all expensive brands. Go OEM and call it the day because you can’t take your chances with brakes
but oems put slotted and drilled brakes on performance cars all the time. its more about getting quality parts for your use case. i’ve only had great experiences with EBC and Z1 slotted brake discs. the drilled ones that failed were some cheap autozone specials that came on the car when i bought it.
Please stay away from EBC brake rotors! They are not heat-treated and they market them as performance brakes. They will deform within the first few times getting hot! I've personally gone through 3 sets of EBC brake rotors within 2 years driving casually on the Nürburgring thinking there was something else wrong with my 350z. Once I got a pair of heat-treated DBA brake rotors all the problems went away.
the amount of weight saved by drills is negligible. they're not drilled specifically because they look cool, but they are offered as options on new vehicles in part for that reason.
Yeah you forgot that dust builds up in the slots making them prone to overheating which in turn will warp , thus having to replace the entire rotor. You also forgot to mention that cross drilled rotors provide better stopping power in wet conditions as opposed to slotted rotors..Everything has its up’s and downs. Please do your homework.
I upgraded to some drilled and slotted front brakes for my BMW, and some Green Stuff pads, and immediately noticed the brake bite was so much more positive. Brake fade also was cured, and they made a cool sound whilst stopping.
Did you buy this car new?
honestly i prefer the slotted look over drilled
This video right here. Underated.
Except he left out drilled and slotted brakes
As a family man, someone who’s not really into stopping/driving hard, blanks are my rotor of choice.
This was great info for me. Because I was just doing some research and wanting to do a upgrade.
Brembo vs EBC drill and grove now I know to just get the grove and I'm going with brembo all round due to finding out EBC use a softer material👍🏿
On my family’s 2011 Honda oddessy running drilled and slotted rotors with ceramic brake pads makes a cool noise when braking harder than usual
I got 312mm drilled Brembo XTRA rotors and Brembo XTRA pads on my 1.9TDi Audi A3 and it brakes harder than a F1 😂

Probably your caliper sticking. I've had this happen on every vehicle I own due to the dry and dusty conditions around here. Kills the grease.

Brembo extra all round
Drilled is the most efficient design.
for cooling, yes. for other aspects, like longevity, not so much
I like slotted brakes…They can’t get shaved incase of warping however

The important part is you are less prone to brake fade because solids have more mass in the rotor for both friction and heat dissipation. Slotted rotors do look nice though.

slots are not cut very deep and the reduced mass would be very small and wouldnt make a significant difference at all
I use dimpled
How are gases going to get caught between the pads and a spinning rotor?

No holes on rotors.
What’s the best brake rotors for 2018 Alfa Romeo Giulia 2.0L?
Factory ones or ones from a quadrafoglio
quadrifolgio is probably a great option
I work at Porsche as a mechanic and these cracks are only dangerous from a certain length or when they go from one hole to another.
so it's still dangerous then. I mean how often does the ordinary man check he's brakes 🤔
I think the ordinary man doesn’t drive like this.

I use slotted rotors on my Saleen, but the brake dust is crazy. Any recommendations on pads that don't create as much dust? Thanks!
Ceramics produce the least amount of dust but have the worst bite and are hard on rotors
@@benshawley2703
Thanks. I'll see if I can find a company that's developed a ceramic that has better bite and causes less damage.
ceramics for sure! i used EBC yellows for a while and liked them. currently using carbotech race pads and they do dust up a decent amount - not designed for street use at all tho
trying hawk hps 5.0 pads soon
@@ChrysGaines
Maybe I'll just start there. They certainly couldn't be any worse than what Saleen put on there.
Drilled rotors are for cooooling , that’s why they are on sports cars
I think "drilled" rotors are designed to be an expendable for the track. They do their job for the day, then they get replaced.
that makes some sense. track rats are going through consumables quickly anyways
What about carbon fiber brakes
Zero practical use on a street car, have to warm up before it bites but great for track use.
Are willwoods any good?
Yes
definitely, although they’re not impervious to the occasional issues, like what That_S14_Z06 guy had

Of course they are, the only time you will feel the effects of the cooling is on the track.

I heard blanks are best cause they don’t have the issues drilled and slotted do. Went with those for the project car
There's no need for them on escalades and expeditions, it's the fucking soccer moms that can't drive that require upgraded brakes
And yet the experts say different.
Back in the late ‘90s, I actually needed cross drilled rotors on my Jetta on the street. I got brake fade a few times and it was scary as fuck.
