Brembo GT 380mm BBK owners, anyone know the size of the hex bolt holding the front caliper to the front carrier? This is the older GT kit using the 4 piston caliper not the 6 piston caliper.


Basically what tools and size of tools, will I need to pull the Brembo 4 piston caliper from car?


Pretty sure the 355mm and 380mm use the same tools.


Thanks for the help.

LOL sounds like a plan.

I hope it does not involve the hassle of you pulling the wheel.

The Brembo F50 front calipers and F40 rear calipers are secured to the mounting bracket by two bolts that require a 10 mm Allen socket to remove them. It's likely the bolts have locktite on them so you will probably need a good breaker bar for leverage.

I've found it easiest to leave the braided lines attached to the caliper. To remove the braided lines from the hard lines requires an 11 mm flare wrench although you might be able to break the nut loose with an open end wrench if they aren't super tight.

When removing calipers, I use a board to depress and hold the brake pedal a bit before loosening any brake lines. This results in almost no loss of brake fluid while the calipers are off the car.

Lastly, be careful not to lose the washers that might remain stuck in the calipers. If the washers don't come off with the bolts, carefully pry them out of the caliper mounting holes so as to keep track of them.

Hope this helps.
