Questions and answers
Q1. What exactly is the problem?
On the rear axle of vehicles fitted with carbon ceramic (CSiC) brakes, the stainless steel screws fixing the rotor to the
metal bell may fail due to stress corrosion cracking if the vehicle has been used in extreme salt environments.
The customer will experience a noise when a screw fails and the brake continues to be 100% effective. However, if
the affected disc was to lose 8 of the 10 screws there would be a loss of braking at the rear wheel. Bentley is not
aware of any vehicle losing greater than 3 screws .
Q2. Which vehicles are affected by the fault?
Continental GT I GTC I Flying Spur vehicles fitted with CS iC brakes before June 2010.
Q3. What is the effect of this condition?
The loss of a single screw will not have any adverse impact on the braking performance of the vehicle. The system
can continue to operate correctly with up to 8 out of the 10 screws missing. There have been no reports of any
vehicles losing more than 3 screws
04. How long does it take for the issue to be detected
This is dependent on the level of exposure the vehicle has to road salt (or sea salt). Vehicles exposed to no or low
levels of salts will not fail
Q5. What do you intend to do about this?
The affected vehicle will have the existing stainless steel screws replaced with new titanium screws that are not
susceptible to stress corrosion cracking
As the design of the front joint is substantially different to the rear no problem with stress corrosion cracking exists.
However, Bentley has decided to change the front disc screws to titanium to ensure commonality across the vehicle
Q6. Can I use the vehicle before the recall has been conducted?
If no screws are missing the vehicle can continue to be used . The presence of the screws can easily be checked by
looking through the spokes of the wheel to the brake disc. However, an appointment with a Bentley dealer should be
made immediately.
Q7. How long will it take to change all the screws?
Approximately 3 hours. Each disc has 10 affected joints , and each individual joint is made up of a large number of
parts (including the screw). Each joint must be carefully disassembled and re-assembled

QB. Have there been any incidents or accidents as a result of this issue
No, there have been no incidents of loss of brake performance

Check

Figure 1
1.

If the vehicle is not already listed as repa ired in the "Repair history" (in ElsaPro) , check the disc retaining bolts on
the vehicle. If the brake discs are already secured with bolts identified as "New" in figu re 1 then this document is
not applicable. If any disc securing bolts are identified as "Original" as shown in figure 1 then carry out the
required work in accordance with these instructions . Note: Due to previous service work it is feasible that a car
may have one disc secured with "Original" bolts and another disc secured with the "New" bolts in this instance
only replace the bolts where the old "Original" bolt is present.
