SuperSport 4 channel anti-lock brakes, Brembo: This is what I have on my 2008 WRX STI, and I'll tell you now that they are not perfect. After washing, my Brembo brakes will absolutely lock frozen (rusted) if I fail to drive it within 48 hours. In other words, If I wash it and park it in the garage without driving it for two days, it is almost impossible to break free of the lock the Brembos develop. Will the Brembos on the 2011 GT be any different?

 

What exactly is locking them up?

Sounds like some problem that has nothing specifically to do with brembo.

 

I believe that it is rust. After washing it, I drive the STI 40 feet into my garage to let it dry - no heating up the brakes takes place.

 

are those aftermarket?? not familiar with the WRX brakes. for the stang factory application would have to be able to stand a much harder abuse cycle than that to pass quality control.

 

It's a fairly common issue. Usually occurs when people wash their car and park it with the E-brake on. The continuous contact ensures that when the fine coating of rust on the rotor develops the pad gets "stuck" to the rotor. There are, to my knowledge two ways to approach the problem:

1) Wash the car, Drive the car, and do some braking to heat up/dry the rotors/pads
2) Wash the car, and use a leaf blower or similar tool to blow the water out of the wheels/rotors/pads.

 

Or...just don't wash the car!

 

Sounds like a defect. My friend has the same year STI and does not experience this.

 

Or you could drive it around the block and use the brakes a couple times to dry off the rotors...

 

FYI I have Brembos on my 06' GT and do not have this issue.

 

They are factory - not aftermarket.

 

My 997 does this with the stock OEM brakes...

 

Exactly, I just have to move my car a few feet after a few hours.

Well, I hope that the Brembo brakes on the Mustang won't have this problem.

 

EVERY car I've ever had, this happens to.

This is not a brembo issue at all.

 

Depends on outside temp (or garage temp).... If your garage only has a slight grade, leave it in gear and use a wheel chock instead of the parking brake.

If you are having the issue now, you'll have it on any vehicle the has rear rotors.

 

My '94 RX7 will get a slight tightening, but not 1/10th of the brake seizure that the STI has. I haven't had but one vehicle with rear drum brakes in the last 20 years, and none of the other six had ever had this extreme brake seizure either. I cannot exaggerate just how seized the brakes were; it was ridiculous.

 

Brake pads must have a pretty high iron content.

 

I'm going to see what Subaru has to say about this. As it is, my wife wants an automatic (hence our interest in the 5.0), so we might be getting rid of the STI. Time will tell.

 

Ok, so what exactly happens?
You wash it, you let it sit, rust builds up on the rotor and glues the e-brake to the rotor.

How exactly do you get it off?
Any of my vehicles that it happens to, I just release the e-brake, roll or gas backwards a bit and 'thud' the rust breaks free... one good brake cleans the rust off the rotor itself.

 

my moms parking break sticks on really cold nights whether the car is washed or not
