Hey everyone,

I bought

Front Brake Pads : Ferodo # FDB 1001
Rear Brake Pads : Ferodo # FDB 1672

for my 2008 CFS, they did not come with sensors. I thought the fronts were built in.

Does anyone have the VW / Audi parts numbers or comparable to order?

thanks in advance

 

wow - i was about to buy 1001 - today cancelled the order.

only fronts are w/o sensors or rear too?

i need front and rear with sensors - anything you will find pls share.

 

The sensors were not included with front or rear it was the pads only, thats why i need the sensors.

I am sure I can get them, just not sure of the part #

 

try febi/bilstein:

16558 - rear
173724 - front

btw - you can alway give the VIN to the seller to find right fit for you.

 

I would rather not have to return them / buy new ones. They seem correct just no sensors.

 

Hello Guys,

On the Bentley brakes, the fronts use a simple disc contact sensor type found on many cars. The rear does not use sensors like these. Instead, when doing a rear brake change the correct way, the thickness (in mm) of the new pads are programmed into the rear brake module, then the computer keeps track of wear and will issue a dash warning when the pads wear to 3mm (I believe memory serves).

I did a writeup on this a few years back and can be read here:

Changing Rear Brake Pads Conti GT - 6SpeedOnline - Porsche Forum and Luxury Car Resource

 

Hey , thanks I looked it over.

So the rears there is no sensor wire because the brake module is measuring the thickness?

The fronts probably use a standard VW/Audi sensor(s)?

most replacement pads I see on ebay have what almost looks like a builtin sensor to the pad

 

Yes, Bentley use a much more sophisticated rear brake system. Not only do you program in the brake pad thickness which the computer then sets and begins to subtract from that as the calipers close more and more with wear, but the system also uses an "inclination" system. With inclination, the parking brake uses different forces given the inclination of the car when parked. In other words, if the car is parked on a sloping road, the brake force is greater than if the car is parked on a level plane. The inclination setting should be recalibrated too, each brake pad change and I covered that in my writeup.

One thing about looks - You cannot look at a brake pad to determine how it might use sensors on your car because hardly any car has brake systems that are unique to it. Instead, that pad might be used in dozens of other applications, maybe where an old fashioned brake sensor is used and needs the notch. A good example of this is my Aston Martin DB11. I changed rear pads on it and it uses the same brake pad (same Brembo caliper) as used on the 2010 to 2012 Corvette ZR1. No parts places list replacement pads for it (a trick the factory uses to drive business to dealers) but if you know the brake systems, you can get around that kind of nonsense.

Hope it helps,
