Notices – Read and Follow BEFORE ATTEMPTING INSTALLATION
• All installations require proper safety procedures and protective eyewear.
• All installations assume basic mechanical skill and a factory service manual for the vehicle on
which the installation is to be performed.
• All references to LEFT side of vehicle always refer to the Driver’s side of the vehicle.
• Any installation requiring you to remove a wheel or gain access under the vehicle requires use of
jack stands appropriate to the weight of the vehicle. In all cases Baer recommends jack stands
rated for at least 2-tons.
• A selection of hand tools sufficient to engage in the installation of these products is assumed and
is the responsibility of the installer to have in his/her possession prior to beginning this
installation. All installations, which require removal of hydraulic hoses and/or bleeding of the
brakes, require appropriate fitting/line wrenches, as well as a safety catch can and protective
eyewear. Other than these items, if unique or special tools are required they are listed in the
section for that step.
• ALWAYS CONFIRM WHEEL FIT PRIOR TO BEGINNING INSTALLATION OF ANY BRAKE
SYSTEM OR “UPSIZED” ROTOR UPGRADE! In addition to already having checked fit using the
Baer Brake Fit Templates available online at www.baer.com, always place the actual corner
assembly or a combination of the caliper assembly fit onto the rotor into the actual wheel to
reconfirm proper clearance is available between the caliper and the wheel before proceeding with
the actual installation.

Connect park cables as shown in photo 2. If the cables on your truck have the bead end rather than the
loop (the vast majority have the loop, we have seen very few bead ends) you will need to purchase the
replacement cables from GM for your specific application. Cab style, bed length, 2 or 4WD will need to be
specified. All cables from GM are loop only. If you have questions on this, call your Sales or Tech
Representative at Baer.
Before driving, review the Rotor seasoning/Pad bedding procedures. These are supplied with your
system or can be downloaded from www.baer.com/bedding
For service and replacement parts, contact your Baer Brake Systems Representative at 602-233-1411,
