BREMBO brake rotors - comments?

[Shawzy]

Considering a set of cadmium-plated BREMBO's for my '79 911SC rear brake discs (current ones are warped nicely - beyond machining I think).

I am hesitant of aftermarket parts normally, but I associate BREMBO with quality for some reason.

Any comments/suggestions?

Anyone had bad luck with these?


thanks....

Brembos? The only bad luck with them is the hit your wallet will take

As long as they aren't the drilled ones, there shouldn't be a problem.

They are drilled - why is this a problem???

I've had Zimmerman cross-drilled rotors on my 78SC as a daily driver and several track events. No problems except I have a little better braking in the rain.

I don't think you can go wrong with Brembo OEM replacement parts.

Great.

I can get them wholesale for $130 a pair not far from home. He ships internationally I think (I caught this deal on EBAY).

No they aren't hot (i.e. stolen). This guy does high brembo volume and can sell low.

There was a show about Brembo brakes a few weeks ago. It showed the brother and sister who started the company by finding a niche market. FYI...

The rotor stays straight with the brake pads even when the wheel is flexing. They said there can be as much as 30% reduction in contact area when the rotor flexes with the wheels.

They also pointed out that tradition brakes do most of the work on the front edge of the brake pad. The Brembo brakes put larger calipers on the back side to improve contact between the brake pad and rotor.

They mentioned that NASCAR has almost all gone to Brembo brakes and that Harley Davidson is/was their primary customer.

If you do go with Brembo's or if anyone else has them, please let us know how they perform compared to Porsche's stock brakes.

Here we go again.
If you aren't doing track events it won't matter. The drilled rotors won't pass tech in my PCA region. The problem is, the thin Carrera and even thinner SC rotors don't have much meat and drilling them creates stress risers. The Porsche factory rotors you see with holes are not drilled. Modern brake pads don't produce the gasses that the holes were designed to vent. Aside from making the rotor lighter, they solve a problem you don't have.

Thickness? The stress risers are caused on the surface, due to thermal and physical(loading) stresses. . . did I say, on the surface?
The "cast hole solution" is very old. Drilled and chamfered with the right material/construction is the current solution.
. . .unsrung, rotating mass can never be light enough; it's always "a problem we have."

Edit: FWIW, I don't like those Brembo drilled rotors. . . .not enough holes.

brembo rotors are of good quality. i have used them in the past with no problems.

p.s. some parts salesman claimed that brembo makes the factory rotors for all ferrari. i didn't believe him, but maybe it's true?

Brembo makes Porsche and Ferrari brakes. The Porche brakes are made to Porsche specifications - a bit higher standards than Brembo's specs I think. For example, I think the Porsche Big Reds have thicker bolts holding the caliper halves together than the Brembo version.

Speaking of Ferrari, the 360 Modena has racy looking drilled rotors. The racing version of this car (Ferrari Challenge) has solid rotors.

The racing rotors that are drilled are thicker and more suitable for drilling. Alcons for instance.
