Brakes still suck

just do slotted rotors and upgrade the pads in the rear, along with ss lines.

Yeah i figured as much, could it be a progressive size just like the 6 pot porsche upgrade? Guess id have to call VWR or APR to find out

Yeah.

However, I remember seeing either on this forum or on MkV a profile photo of a VWR prepped car and it had the 6-pot brakes up front but stock GTI brakes in the rear. If I recall it was a spec series in Germany and all the cars were configured like this...

I'm pretty sure our handy dandy fancy ABS computer modulates and handles bias dynamically...

A "spec" car likely has all kinds of custom stuff going on to make that work..

No..Bias is controlled by hydraulics and line pressures matched to the front and rear braking capabilities..You could have your front brakes locking and triggering ABS if they overpower the car, while still having the rears rolling along merrily if things aren't matched well. It's all covered in the Cayenne conversion threads.. Dynamically the car would be touchy.

I don't think the ecu does that in our car.

Typically in fwd, whether you have bbk or not, the brake balancing is determined mainly by pad compound. Typically in a nose heavy fwd car, you want a more aggressive pad in front and slightly less in rear. Also you need proper tires to handle the increased braking torque or your brakes will overpower the car.

Excellent set up is Carbotech XP10 (F) and Carbotech XP8 (R). Works will with R Comps as well as Starspecs, AD08, RS3, RE11 or the likes.

Having a BBK doesn't make you brake harder. That is a myth. What it does is it gives you a larger 2 piece rotor for better heat dissipation and a stiffer caliper for consistent stiff pedal feel. Also it reduces unsprung mass of your brake system by upwards of 15 lbs a corner which is a huge amount of unsprung weight. If you want to know what 15 lbs a corner feels like, compare your stock detroits to a lightweight OZ/Enkei/Volk/BBS wheel.

BBK to cure fade.
Pads to stop your car faster
Tires to make it all come together.

Halfway down the page...

EBD will proportion the line pressure to each caliper based on the available stopping power though....


Reining the thread back a bit though, OP still need to make sure he actually have a properly working system as is before he jump to any upgrade to cure his "fade".

.

Yeah...EBD likely throws some new wrinkles into the equation...

Exactly, MK6s have BA and EBD. How do you think we get away with such high initial rear bias yet don't have GTIs spinning off every other on ramp?

Not sure if serious...

Cough... 59th street bridge? Queensboro?







"The Queensboro bridge in New York City has seen its third major accident involving a Volkswagen since March. According to The New York Post, a 2007 Volkswagen Golf lost control while exiting the bridge, struck scaffolding erected outside of a building and landed on top of a parked livery vehicle. The driver of the VW was treated at a local hospital for minor injuries. No one else was harmed in the incident.

That's a better outcome than in both of the previous accidents. The post reports that in April, the driver of a Jetta lost control in that exact location and spun into two store fronts. The driver later died of her injuries. Likewise, in March, a single-car accident at the off ramp resulted in the death of a pedestrian. The driver of that particular Volkswagen Golf lost an arm as a result of his injuries.

At this point, it's unclear what will be done to curb speeding on the off-ramp. Hit the jump to view a news report of the latest incident."

^ I'm thinking it's more of the hideous wheels and not the brakes. And those were said to be Golf's not GTI's. Just saying...

EBD and other alphabet soup acronyms apply to GTI & Golf & MKV Jetta.
And yes, the wheels are hideous.

Looking forward to providing you all with some serious insight on the Forge BBK.
The claims here less proof need to be further examined. Documentation or actual proof has yet to be seen on the following claims:
"Chinese knock-offs"
"6 piston affects brake bias"

I refer to Tecni (current MK6 owner with Forge BBK) and Sean from Forge Motorsport.

wow. i had no idea. hah well at least no VWs are spinning off on-ramps in Boston.

Even after I upgraded the pads and brake fluid they stock brakes still sucked, ended up going with the Forge Motorsport Front Brake Kit and SS lines on my 2011 GTI.
