Continental Flying Spur - Continental GT and Continental GTC Front Brake Hose
Re placement

Release date: Aug 15, 2013

Condition
Due to a change in material the original specification front flexible brake hoses are no longer available, therefore the
original specification front flexible brake hoses cannot be supplied by Bentley Motors for the following vehicles only:
Continental GT
Continental GTC
Continental Flying Spur

Bentley Motors has developed and sourced alternative front flexible brake hoses. Along with the front brake hoses there
are other components which must also be replaced as the new specification brake hoses are not interchangeable with the
original caliper fixing bracket and metal caliper brake pipe (Unless stated)
NOTE· The rear flexible brake hoses are also made from the new material however the rear hoses are not affected by this
TPI as they are fully interchanoeable

Should a new replacement front caliper be required and the vehicle is fitted with carbon ceramic brakes, the caliper will
arrive with the original flexible brake hose bracket fitted, should the vehicle already have the latest specification hoses
fitted the caliper bracket should be removed and the latest specification bracket will require fitting as per instructions within
this TPI.

Technical Background
All relevant parts should be ordered dependent on which system is fitted to the vehicle, the two types of system are the
Iron brake system and the Carbon ceramic brake system . The parts should be ordered as detailed within the parts
information section of this TPI.

In the event that one front flexible hose requires replacing outside of the recommended service interval and the vehicle
has the original front flexible hoses fitted please replace both front brake hoses and all applicable parts as described
within this TPI.

Production Solution

Service
IMPORTANT: For clarity Figure 1 shows the Left hand front and was taken using a Continental GT with the Iron brake
system fitted . Please follow this procedure for the Carbon brake system although the appearance of some components
may be different than the Iron brake system.
Left Hand Front - Iron brake system

Always cap the ends of open pipes to prevent dirt ingress and fluid loss
1. Referring to the Workshop Manual Rep.Gr 47 - Remove the original Left hand front brake hose (Figure 1 point A)
- Remove the existing caliper bracket (Figure 1 point 8) and disconnect the brake pad wear connector and road wheel
speed sensor loom grommet from the bracket

- Remove the metal caliper brake pipe (Figure 1 Point C) IMPORTANT· There is no requirement to replace the metal
brake pipe on GT and GTC vehicles with the carbon ceramic brake system

Referring to Figure 2 the Continental Flying Spur requires the right and left hand wheel arch brake pipe bracket and fixings
replacing
The Torque for the two retaining Bolts (Point A) and the retaining nut (Point B) is 12 Nm

2. Referring to Figure 3 - Fit the new flexible brake hose with a new retaining clip (Point A) CAUTION : The pipe will only
locate into the bracket one way only, to clarify correct orientation the two fixed rubber protective doughnuts will be

• positioned as shown in (point B)
- Torque tighten the 11 MM brake pipe nut to 15 Nm

Figure 3
3. Fit the new brake caliper flexible pipe bracket as shown in Figure 4, ensure the bracket is seated and located correctly
onto the caliper, use two new fixings and Torque to 23 Nm

Figure 4
4. The next step requires the flexible brake pipe locating into the bracket please follow the next key points
- Offer the pipe into the bracket, IMPORTANT: Should the pipe require turning to allow the pipe to locate into the bracket
turn the pipe clockwise as this will minimise the twist of the hose as shown in Figure 5 until the two tangs locate within the
bracket

IMPORTANT: Referring to Figure 9, Check the routing of the pad wear indicator loom (Point A) , the loom should be
positioned behind the brake pipe (Point B) and pipe bracket (Point C)

8. Replace the Right Hand Front flexible brake pipe by repeating steps 1 to 7

Please note when locating the flexible brake pipe on the right hand side, the pipe must be located within the bracket by
turning Anti - Clockwise as this will minimise the twist of the hose as shown in Figure 12 until the tangs locate within the
bracket
