Brake System Bleed
ABS Automated Bleed Procedure
Do not remove the reservoir cap while depressing and releasing the brake pedal. If the cap is removed while depressing and releasing the brake pedal, pressurized brake fluid being returned to the reservoir may leave the reservoir. Personal injury or vehicle damage could result.
Do not allow the HBCi pump and motor to run more than one minute continuously. Allow two minutes cool down time between pump run times. Extended pump and motor run time could create excessive heat and damage the pump and motor assembly.
Perform steps 1-4 below t...

Hydraulic Brake Systems -> Adjustments -> Height Sensing Proportioning Valve
Vehicle: 2007 Hummer H3 3.7 L5 GAS
Height Sensing Proportioning Valve
The height sensing proportioning valve must be adjusted whenever the valve and/or linkage is disassembled or removed for service. In addition, adjustment should be inspected if excessive front wheel lock-up is experienced with a lower than desired brake application rate when vehicle is at or near maximum GVWR.
- Raise and support vehicle, leave wheels on and allow axle to hang freely.
- Remove lever retaining nut and disconnect lever from valve shaft, Fig. .
- Rotate valve shaft to permit installation of correct adjustment gauge, Fig. , ensure D shaped hol...

- Remove tire and wheel assembly.
- Compress caliper pistons until they bottom in bores using suitable clamp, Fig. .
- Disconnect brake hose at caliper by removing inlet fitting bolt.
- Remove mounting bolts and caliper.
Inspection
Should it become required to remove the caliper for installation of new components, clean components in denatured alcohol, wipe dry using lint-free cloths. Blow out drilled passages and holes using compressed air. Inspect dust boots for punctures or tears. If punctures or tears are...

Anti-Lock Brakes -> Advics -> Description
Vehicle: 2007 Hummer H3 3.7 L5 GAS
When wheel slip is detected during a brake application, the ABS enters anti-lock mode. During anti-lock braking, hydraulic pressure in the individual wheel circuits is controlled to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold, or increase hydraulic pressure to each wheel brake. The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.
During anti-lock braking, a series of rapid pulsations is felt in the brake pedal...

Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2007 Hummer H3 3.7 L5 GAS
Certain general service procedures apply, regardless of whether the brakes are vacuum or hydraulically assisted. Only top quality, clean brake fluid should be used. More seals and valves are used with power brake systems than with ordinary brakes, so an inferior brake fluid will do much more damage. For the same reason, ensure all dirt is kept out of the system. Additionally, on models with hydraulic assist brakes, care must be taken not to mix the fluids of the booster hydraulic system and brake hydraulic system as the fluids are not compatible.
If the power unit fails, the brak...
