DIY: BBK (big brake kit) for e90/e91/e92/e93

longtran · 10-22-2006, 11:31 PM

yo guys, here is a DIY big brake kit for e90/e91/e92/e93. i am going to try my best do explain what i did. everything was easy. the only thing i thought would be hard is bleeding the brakes. if you know how to bleed the brake line, you are good to go.

tools needed:

17/18mm socket
socket wrench
10/14mm open end wrench
adjustable wrench
vise grip wrench
6mm hex wrench
fluid catcher
brake line pincher
dremel with a cut off disc
zip ties

remove 2 18mm bolt thats hold the caliper. you can remove the caliper and use some zip ties to hang it somewhere. say hi to me

loosen the 6mm hex on the face of the rotor

remove the rotor.

now pinch the brake line with the pincher.

with a 14mm open end wrench unloose the brake line from the caliper.

now you should have everything off.

trim the corners with the dremel so the bigger caliper can clear the heat sheild.

before

after

now reverse the install with the bbk. install the stainless steel brake lines if your kit comes with them.

here some pictures putting the BBK on.

tight the brake line on the caliper first and find something to hang it.

now install the rotor.

bolt the caliper on.

the brake sensor does not work in BBK. just zip tie the sensor somewhere, so it wont get tangle while you are driving.

now bleed the brakes. have fun!!!

thanks ///Matt :rocks:

That Was Nice dawg!

As I was looking at the pictures I was thinking how in the hell can Long spend SOOOOO much time keeping EVERY SINGLE BOLT CLEAN LIKE THAT?!!!

And then I saw his hub with NO RUST and I thought he hand cleaned them down.

Funny
Last picture was a 335!!!!

THAT explains it ALL

Great DIY man. GF can brake on a dime now!

Lol, I was thinking the same thing. "dang that hub is immaculate" What is that brake sensor for btw? The car doesn't throw a code with that sensor not connected?

sensor is for when the brakes gets too low it will prompt a warnin. no need for this. just watch your brakes, jusst like the good old days.

the whole kit is 3400. the oem rotor will not work with just the caliper.

neuronpetkowski · 10-23-2006, 10:38 AM

That's kick ass, long. I'd like to get a BBK, but man...that's a lot of green for some red behind the wheels...

shragon · 10-23-2006, 10:45 AM

nice!

That's why I just painted my calipers red.

Nice write up long! The 335 looks awesome with the BBK.

How about performance? Do they really stop you quicker?

bluegoldjason · 11-13-2006, 04:07 PM

why did you only do the fronts?

Fronts provide most of the braking power.

bluegoldjason · 11-13-2006, 04:27 PM

i'm aware of this... but come on, half of a BBK is for appearance

Backattack · 11-19-2006, 01:01 AM

Excellent write up; does the car actually stop any sooner?

ward · 11-19-2006, 02:24 AM

pinching the line seems like a bad idea to me

Turbo Squid · 12-05-2006, 11:22 PM

Great job man.

So $3400 for just the fronts? There no way. What brand is it? I see JBT written on the rotor, but I've never heard of that company. I'm sure Brembo will come out with an application for e92's.

How does it perform now?
