Brakes
Battery Disconnect
Disconnect the battery before servicing the
hydraulic brake system. It is critical to
disconnect the battery before bleeding the
system, replacing the pads, or any other
work. The battery must be disconnected to
prevent the brake master cylinder from
pressurising the hydraulic system during its
automated self diagnostic tests that can
possibly occur when a door is opened or the
remote key is present.

Warning
To avoid personal injury and/or vehicle
damage, always disconnect the battery
before performing service work on the
hydraulic brake system. Bleeding the
brake system with the battery connected
can lead to excessive pressurisation of
the system during automatic diagnostic
tests or diagnosis of a leak or air in the
braking system. A Diagnostic Trouble
Code (DTC) may set and vehicle speed
may be limited.
Brake Fluid
Replace existing brake fluid with a qualified
high performance brake fluid from a sealed
container. Brake fluid with a dry boiling
point >310 °C is qualified. If high
performance brake fluid is used, replace it
with GM approved brake fluid before driving
on public roads. If high performance brake
fluid is in the vehicle and the age of the
brake fluid is over a month old or unknown,
replace the brake fluid before track events
and competitive driving. Do not use silicone
or DOT-5 brake fluids.
Check the fluid level before each competitive
driving event.
Brake System Flushing & Bleeding
The J55 brake system requires specific
processes for bleeding and fluid flushing.
It is recommended that this be performed
by a dealer.
Correctly bleeding the brake system is
required for optimal operation of the
hydraulic brake system.
Brake Leak Detection
The hydraulic braking system has advanced
diagnostic capability to help detect hydraulic
leaks, trapped air, and other performance
issues. These diagnostics are active when
the hydraulic system is powered. In order to
avoid inadvertently setting a leak Diagnostic
Trouble Code (DTC), disconnect the battery
before servicing the brake system.
If the vehicle sets a DTC related to a brake
system leak, the Brake System Warning
Light will come on and vehicle speed may
be limited to 100 km/h. Any time a leak
DTC is set, the vehicle should be inspected
carefully for evidence of a leak and should
be repaired immediately. See your dealer.
Brake Fade Warning Assist
The Brake Fade Warning Assist system
monitors the performance of the brake
system. If the system detects brake fade,
or if the brake fluid is near the boiling point,
the driver will be alerted.
The Brake Fade Warning Assist system is
designed for use with the factory-installed
brake pads or GM-approved replacement
pads. If the brake pads on the vehicle need
to be replaced, use GM-approved brake pads.
If this is not done, the brake fade warning
system may not function properly.
