The purpose of this bulletin is to inform dealers of an improved service strategy to aid in the replacement of hydraulic brake pipes for the above listed vehicles.
Customer Care and Aftersales (CCA) has released pre-formed and pre-flared hydraulic brake pipe kits.
These kits can be used anytime replacement of the entire brake pipe assemblies is required. These kits include all the pre-formed and pre-flared brake pipes
needed when replacing the entire brake pipe assembly, except the rear axle crossover pipe. If the rear axle crossover pipe requires replacement, refer to the
appropriate parts catalog for ordering and the Brake Pipe Replacement procedure in SI for installation instructions. The following procedure describes how to
install these kits.
Replacement Procedure (Pickup and Cab Chassis)
Removal
Warning: Brake fluid may irritate eyes and skin. In case of contact, take the following actions:
•
Eye contact—rinse thoroughly with water.
•
Skin contact—wash with soap and water.
•
If ingested—consult a physician immediately.
Caution: Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause
corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in
contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.
Caution: Care should be taken to ensure that dirt, water, grease, or other contaminants do not enter the new brake pipes and threaded end fittings when the
pipes are being installed into the vehicle. Use tape or other appropriate methods to cover the threaded end fittings and the ends of the pipes to prevent dirt,
water, grease, or other contaminants from entering the pipes. Remove all protective measures before connecting the end fittings to the master cylinder, brake
pressure proportioning valve (where equipped), brake pressure modulator valve (BPMV), or flexible brake hoses.
Caution: Cleanliness is important for the proper function of the hydraulic brake system. Clean all dirt, water, rust, etc from the areas adjacent to each brake
pipe tube nut before removing the brake pipe tube nuts. Take care to ensure that no contaminants enter any hydraulic fittings or openings during removal or
installation of the brake pipes.
Caution: Before removing any brake pipes from the master cylinder, ABS module (BPMV), and the brake pressure proportioning valve (where equipped)
identify the port locations. On the BPMV identify the port location for each hydraulic component (e.g., Master Cylinder Primary, Master Cylinder Secondary, LF
corner, RF corner, LR corner, RR corner, Rear Brake). On the brake pressure proportioning valve identify the port locations for each hydraulic component
(e.g. master cylinder primary inlet, master cylinder primary outlet, master cylinder secondary inlet, master cylinder secondary outlet, pre-charge pump). When
installing the replacement pipes, ensure that the replacement pipes are installed in the correct port locations on the master cylinder, BPMV, and brake pressure
proportioning valve, where equipped. If the pipes are not installed in the correct port locations on all the hydraulic components, the brake system including the
ABS system and/or TCS/VSES Stabiltrak system (where equipped) will not operate correctly and may result in damage to the hydraulic brake components.
Note: This procedure does not comprehend specific vehicle models or brake system configurations. The illustrations may not exactly reflect the vehicle being
repaired. Some LD pickups and LD SUVs may be equipped with a brake pressure combination valve and a brake pressure modulator valve pre-charge pump.

The brake pipes attached to these components should be removed and replaced with the replacement pipes provided in the service kit.
Note: This procedure is not intended for the repair or replacement of a single damaged brake pipe. This procedure is for the replacement of the entire brake
pipe assemblies with pre-formed and pre-flared components.
Note: Remove the brake pipes from the existing routing clips carefully to avoid damaging the clips as all the clips will be re-used. The new brake pipes will be
reinstalled into the existing clips. After installing the new brake pipes, inspect the routing of the brake pipes to ensure that the new brake pipes do not contact or
rub on any frame, body, or chassis components. Carefully bend the pipes to increase clearance as required.
Note: The brake pipes in these kits are not an exact duplicate of the pipes currently installed on the vehicle. These pipes have a nylon coating to provide better
corrosion protection and may have slightly different shapes and bends and may not exactly match the brake pipes being replaced. Some original equipment
pipes may use flexible hose sections near the master cylinder or brake pressure proportioning valve that attaches to the master cylinder to brake booster
mounting studs. The replacement pipes in this kit will not use the flexible hose sections. The replacement pipes have been designed to fit each vehicle
application. Because of the nylon coating on the outside of the brake pipes, the outside diameter of the pipe is slightly larger than the original pipes, Extra
effort may be required to insert the pipes into the existing mounting clips. It is recommended to finger start all the threaded end fittings into the master cylinder,
brake pressure proportioning valve, brake pressure modulation valve, and flexible brake hoses before performing the final tightening and torque of each fitting.
Note: The brake pipes in these kits may have additional large radius shipping bends to allow the pipes to fit within the cardboard box. Those pipes with
additional shipping bends will have tags on either side of each shipping bend. Carefully straighten the section of pipe between the tags to remove the shipping
bend. Take care not to kink or damage the brake pipes. If a brake pipe becomes kinked or damaged while removing the shipping bends, it must be repaired or
replaced before installation into the vehicle. Take care not to cut, nick, abrade or otherwise damage the nylon coating on the brake pipes during installation.
Note: For Chassis Cab models, due to the installation and mounting of the aftermarket equipment/body on the rear of the chassis (i.e. flatbed, stake bed, box
van, dump body, etc) by the second stage manufacturer or vehicle upfitter, it may be difficult or prohibitive to remove the aftermarket body to enable
replacement of the OEM rear brake pipe. Each vehicle will need to be assessed individually, however, it may be preferable to hand bend a service
replacement brake pipe using GM P/N 88936298 PIPE, BRK (STEEL) (1/4" X 16 FT ROLL) nylon coated bulk tubing available separately from GM dealers,
using GM P/N 15103241 Fitting, BRK PIPE (1/2-20-2A THD) (1/4 TUBE STL) to attach to the ABS module (BPMV) and GM P/N 11609443 Tube Nut (7/16-24
UNS-2A THD) to attach to the rear axle jounce hose. These tube nuts are designed to properly fit over the nylon coated brake tubing. The tube nuts can also
be removed from the replacement rear pipe included in the brake pipe service kit and installed on the hand bent service replacement pipe. Route the hand bent
service replacement pipe from the ABS module (BPMV) to the rear axle jounce hose ensuring adequate clearance is maintained between the pipe and
surrounding components to ensure that the pipe is not damaged in service. Attach the hand bent service replacement brake pipe securely to the chassis
using brake pipe clips, rubber coated P-clips, or other suitable methods. The maximum distance between attachment points or clips should not exceed 457 mm
(18"). If a brake pipe has a directional change (bend) of 30 degrees or more, a clip needs to be located as close as possible to the bend.

Installation
Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Do not use paints,
lubricants, or corrosion inhibitors on fasteners, or fastener joint surfaces, unless specified. These coatings affect fastener torque and joint clamping force and
may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
When using fasteners that are threaded directly into plastic, use extreme care not to strip the mating plastic part(s). Use hand tools only, and do not use any
8
kind of impact or power tools. Fastener should be hand tightened, fully seated, and not stripped.
