Hydraulic Brake System Bleeding (Manual)
WARNING
!
Refer to “Brake Fluid Irritant Caution: ”.
CAUTION
!
When adding fluid to the brake master
cylinder reservoir, use only GM approved or
equivalent DOT-3 brake fluid from a clean,
sealed brake fluid container. The use of any
type of fluid other than the recommended
type of brake fluid may cause contamination
which could result in damage to the internal
rubber seals and/or rubber linings of
hydraulic brake system components.
CAUTION
!
Refer to Brake Fluid Effects on Paint and
Electrical Components Notice.
1. Place a clean shop cloth beneath the brake master
cylinder to catch brake fluid spills.
2. With the ignition OFF and the brakes cool, apply the
brakes 3-5 times, or until the brake pedal effort
increases significantly, in order to deplete the brake
booster power reserve.
3. If you have performed a brake master cylinder bench
bleeding on this vehicle, or if you disconnected the
brake pipes from the master cylinder, or if you have
disconnected the brake pipes from the proportioning
valve assembly or the brake modulator assembly,
you must perform the following steps to bleed air at
the ports of the hydraulic component:
a. If removal of the reservoir cap and diaphragm is
necessary, clean the outside of the reservoir on
and around the cap prior to removal.
b. With the brake pipes installed securely to the
master cylinder, proportioning valve assembly, or
brake modulator assembly, loosen and separate
one of the brake pipes from the port of the
component.
For the proportioning valve assembly or the
brake modulator assembly, perform these steps
in the sequence of system flow; begin with the
fluid feed pipes from the master cylinder.
c. Allow a small amount of brake fluid to gravity
bleed from the open port of the component.
d. Reconnect the brake pipe to the component and
tighten securely.
e. Have an assistant slowly depress the brake
pedal fully and maintain steady pressure on the
pedal.
f. Loosen the same brake pipe to purge air from
the open port of the component.
g. Tighten the brake pipe, then have the assistant
slowly release the brake pedal.
h. Wait 15 seconds, then repeat steps 3.3-3.7 until
all air is purged from the same port of the
component.
i. With the brake pipe installed securely to the
master cylinder, proportioning valve assembly, or
brake modulator assembly, and after all air has
been purged from the first port of the component
that was bled, loosen and separate the next
brake pipe from the component, then repeat
steps 3.3-3.8 until each of the ports on the
component has been bled.
j. After completing the final component port
bleeding procedure, ensure that each of the
brake pipe-to-component fittings is properly
tightened.
4. Ensure the brake master cylinder reservoir remains
at least half-full during this bleeding procedure. Add
fluid as needed to maintain the proper level.
Clean the outside of the reservoir on and around the
reservoir cap prior to removing the cap and
diaphragm.
5. Install a proper box-end wrench onto the RIGHT
REAR wheel hydraulic circuit bleeder valve.
6. Install a transparent hose over the end of the bleeder
valve.
7. Have an assistant slowly depress the brake pedal
fully and maintain steady pressure on the pedal.
8. Loosen the bleeder valve to purge air from the wheel
hydraulic circuit.
9. Tighten the bleeder valve, then have the assistant
slowly release the brake pedal.
10. Wait 15 seconds, then repeat steps 8-10 until all air
is purged from the same wheel hydraulic circuit.
11. With the right rear wheel hydraulic circuit bleeder
valve tightened securely, and after all air has been
purged from the right rear hydraulic circuit, install a
proper box-end wrench onto the LEFT FRONT
wheel hydraulic circuit bleeder valve.
12. Install a transparent hose over the end of the bleeder
valve, then repeat steps 7-11.
13. With the left front wheel hydraulic circuit bleeder
valve tightened securely, and after all air has been
purged from the left front hydraulic circuit, install a
proper box-end wrench onto the LEFT REAR wheel
hydraulic circuit bleeder valve.
14. Install a transparent hose over the end of the bleeder
valve, then repeat steps 7-11.
15. With the left rear wheel hydraulic circuit bleeder
valve tightened securely, and after all air has been
purged from the left rear hydraulic circuit, install a
proper box-end wrench onto the RIGHT FRONT
wheel hydraulic circuit bleeder valve.
16. Install a transparent hose over the end of the bleeder
valve, then repeat steps 7-11.
