rotors weird/ calipers rusted.. .dammit *pics*

Just got my brembo rotors for my 62 from autopartswherehouse.com

i noticed on the sides that part of it is milled out. I'm not sure if this is abnormal because its on both rotors. Maybe to balance the rotor?

However theres a good part milled out.

other rotor not as much milled out

Should I be worried, or is this normal?

I also got rebulid 4 runner calipers from napa and noticed that in one of the pots there was noticable rust.... is this okay?

Haven't really worked on brakes before so i have no clue... Napa kept messing up so I had to go to about 3 napas to finally get there calipers and I'm hoping I won't have to go back again...

Should I put silicone grease on those rubber seals for the pots? the calipers came with some and I;'m assuming thats where it goes.

Any help would be appreciated!!

You decided on the Brembo's huh? Good enough.
No problem on the rotors. That's the way they're balanced.

As far as the rust on the pistons... looks like it's on the exterior.
You have to assume the interior is smooth and rust free. There's only one way to find out.

If you're planning to apply anti-squeak to the back of the pads, the silicone grease would prevent the pads from sticking onto the pistons.
If not, It shouldn't hurt.

If those are brembo rotors i'll eat my hat. There is no way that milling on the outer of the rotor is normal or safe. Send them back, get the correct pair. Landcruiser's may not be sports cars, but safety is safety. If the OEM and suppliers like DBA can manufacture a balance rotor without grinding out behind your stopping surface, then surely the name Brembo can do so as well.

Porsche, Mercedes... Brembo's, Balo's... I've seen them that way and I've used them that way. How many is he supposed to order before he finds a pair w/o milling?
The milled area is on the outer perimeter and inside where a pad won't touch. Granted they're Brembos and could be neater. That's how they're coming.

Contact Brembo USA to see if you have a pair of Chinese knockoffs. Lots of this kind of stuff has been flooding the US for years now. Unscrupulous dealers don't want to know & pass it off as the real deal.

If it seems to good to be real, it probably isn't.

P.S. I got Brembos for my '83 from WorldPac about 3 years ago. I'll bet they're genuine. Reputable dealer = reputable parts.

Thanks for the reply guys, i'm pretty sure they are real brembos.. I just asked a friend who had bought some brembos earlier this year and his had the same milling to balance it. just gotta get all this crap on the car now.

How is it unsafe???

MInes that comes with my rear brake kit have the same mill as well ..

Ever heard of flex? I'd hate to put a decent heat cycle through those rotors and have the outer edge, where it has been machined, crack and dislodge. OEM were never like that, you would expect better from Brembo

Funny, OEM mini were about that thickness and not vented.. And the outer edge is not really used that much. Most of the braking happens in the inner central portion.

I have seen a bunch of these rotors in use, and have not seen one of them "flex" and crack..

This is a FJ60. Not some little ricer racer that is doing timetrails.


The rotors will be fine.

if the rotors are flexing they're going to break at the hub. as long as the calipers are working properly there will be no flexing of the rotor.

if you're talking about heat induced stress, yeah not likely here. thermal stress comes from large differentials in temperature the simply won't be present here. cast iron conducts heat pretty well, the vents in the rotor are there to keep the temps down, and the essentially hollow structure reduces the mass of the rotor that is available to retain heat.

the rotors are fine
