SPECIAL COVERAGE
SUBJECT:

Special Coverage Adjustment – Inadequate Clearance of Fuel Fill Pipe Clamp
to Brake Lines

MODELS:

2011-2014 Chevrolet Express
2011-2014 GMC Savana
Equipped with Hinged Left Side Rear Door (RPO E26)

CONDITION
On some 2011-2014 Chevrolet Express and GMC Savana vehicles, equipped with a hinged left
side rear door (E26), inadequate clearance may result in abrasion to one or both rear brake lines.
This could cause brake fluid loss resulting in decreased brake line pressure, increased brake pedal
travel and increased stopping distance. Alerts announcing this potential condition are: a sudden
increase in brake pedal travel; illumination of “BRAKES” light and Stabilitrak symbol; display of
“Service Brake,” “Service Stabilitrak,” and “Service Traction Control” messages in the Driver
Information Center (DIC); and/or chimes will be heard.
SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 250,000
miles (400,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
Dealers are to replace rear brake lines with pre-formed lines based on vehicle content. The repairs
will be made at no charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
March 23, 2015 are covered by this special coverage and must be submitted using the labor
operation codes provided with this bulletin. Claims with repair orders prior to March 23, 2015 must
be submitted to the Service Contract provider.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties
section in GM Global Warranty Management system. Dealership service personnel should always
check this site to confirm vehicle involvement prior to beginning any required inspections and/or
repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles
may be involved regardless of description or option content.

Rear Brake Line Clearance

Caution: To avoid bending or damaging the new brake lines, ensure the following precautions are
observed:


Carefully insert the new brake lines forward of the fuel pump control module. Refer to New
Brake Line Installation photograph.



Do NOT force the fitting ends of the new brake lines onto the brake pressure modulator valve
or rear jounce hose and crossover pipe mounting bracket.



Ensure the new left rear brake lines (6) do NOT get caught on to the right rear brake lines (5)
during installation. Refer to Rear Brake Line photograph.

Page 5

March 2015

Bulletin No.: 14301



If required, manually separate the new left rear lines (6) from the right rear brake line (5) and
make sure that the new left brake lines (6) latch onto the frame and not the right rear brake line
(5). Refer to Rear Brake Line photograph.



Ensure there is clearance between the right rear brake line and the new left rear brake lines.
Verify that a least 9 mm (0.35 in) of clearance (7) between the new left rear lines (6) and the
right rear brake line (5). Refer to Rear Brake Line photograph.

10. Install the new brake lines.
10.1 Insert the new brake lines (1) forward of the fuel pump flow control module (3).
10.2 Follow the production intent brake line routing along the frame.
10.3 Position the front brake line fittings to the brake pressure modulator valve. Do NOT install
the front brake line fittings to the brake pressure modulator valve.
10.4 Inspect the routing of the brake lines in the left rear wheel opening. Ensure the brake
lines are NOT in contact with the fuel filler pipe, filler pipe clamp, frame, and rear axle.

4070698

The illustration shows the brake line routing on the inboard side of the frame near the left wheel
opening. Inspect the new brake lines (6) for frame contact in the areas that are circled in the
illustration. Also ensure the right rear brake line (5) is NOT contacting the new brake line (5) in the
circled areas of the illustration as well. The old brake line routing (8) is shown to display the
differences between the two brake line designs.

10.5 Inspect the brake line routing on the inboard side of the frame near the rear left wheel
opening. The brake lines should NOT contact the frame and should NOT have a stressed
or tight fitment over the frame.
10.6 Install the brake line mounting clips in the production positions.
10.7 Ensure the brake lines are secured by the mounting clips in the production routing
positions.
10.8 Tighten the rear jounce hose and crossover pipe mounting bracket bolt.

10.9 Clean the underside of the vehicle. Remove brake fluid and dirt from the outside of the
brake pressure modulator and rear jounce hose and crossover pipe mounting bracket
using a shop towel.
Caution: Hand-tighten the brake line fittings onto the rear jounce hose and crossover pipe
mounting bracket fittings BEFORE tightening the fittings to the specified torque to avoid damaging
the brake line fittings, rear jounce hose or crossover pipe mounting bracket.
10.10 Carefully install the brake line fittings onto the rear jounce hose and crossover pipe
mounting bracket fittings. Tighten the fittings to 25 Nm (18 lb ft).
10.11 Connect chassis wiring harness electrical connector to the fuel pump flow control
module.
Caution: To avoid part damage, ensure the bottom brake line (1) is installed on the outboard side
of the brake pressure modulator valve. The bottom line has a tag (2) attached to it. Hand-tighten
the brake line fittings onto the brake pressure modulator valve BEFORE tightening the fittings to
the specified torque.
10.12 Carefully install the brake line fittings onto the brake pressure modulator valve. Tighten
the fittings to 25 Nm (18 lb ft).
11. Bleed the hydraulic brake system. Refer to Hydraulic Brake System Bleeding in SI.

CUSTOMER NOTIFICATION
General Motors will notify customers of this special coverage on their vehicles (see copy of typical
customer letter included with this bulletin - actual divisional letter may vary slightly).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO
NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer/retailer for information on
whether your vehicle may benefit from the information.
