Bleeding ABS Brakes on a Chevy
When bleeding ABS brakes on a Chevy, you can follow these general steps:
1. Relieve Pressure and Check Pedal Height: Start by relieving pressure at the bleed tool and removing it from the master cylinder. Then, check the pedal height and feel to ensure all the air has been removed and the pedal is firm.
2. Bleeding Sequence: For Chevy vehicles equipped with the Bosch 5 ABS system, the sequence for bleeding the brakes is right rear, left rear, right front, and left front. This system does not require special bleeder valves or a special scan tool bleed procedure.
3. Bleeding Older Integral ABS Systems: For older integral ABS systems, bleed the new valve assembly at each brake line fitting one at a time. Remember to close the valve bleed plug before each brake pedal stroke. Continue bleeding until the fluid flowing from the fittings is clear and free of bubbles.
4. Using a Scan Tool: Some GM vehicles, including certain Chevy models, may require a scan tool for bleeding ABS brakes, especially if air entered the ABS modulator during brake service. However, for vehicles with ABS module bleeder screws, it is possible to bleed the ABS without a scan tool, although it may take more time as each wheel needs to be bled separately .
5. Additional Considerations: It’s important to confirm pedal height and feel after bleeding and rebleed if necessary. Additionally, for vehicles without an antilock braking system, the bleeding process can effectively remove air from the system after replacing brake components.
Remember to consult the specific vehicle manual or dealer to determine the exact bleeding procedure for your Chevy model, as different systems may have specific requirements.

Do you bleed brakes with reservoir cap on or off?
Locate your brake master cylinder reservoir’s brake fluid level, usually located under-the-hood. Ensure that your car has the appropriate amount of fluid. While you’re bleeding the brakes, you’ll want to be sure that you leave the master cylinder cap unscrewed but rest it on top of the reservoir.
How many times do you pump brakes when bleeding?
Instruct the assistant to “apply.” The assistant should pump the brake pedal three times, hold the pedal down firmly, and respond with “applied.” Instruct the assistant not to release the brakes until told to do so. Loosen the bleeder screw with a brief ¼ turn to release fluid into the waste line.
Do you have to bleed brakes after ABS module?
Bleeding is required when replacing an ABS modulator or other hydraulic components. It might not be necessary when performing a wheel-based hydraulic repair but you should be careful about not letting in any air into the system.
Do you bleed ABS brakes with engine running?
Brakes are bled with the engine off. A running engine supplies a vacuum boost to the brake system. To properly bleed all the air from the system, there needs to be NO boost. Just pump the brake pedal until a solid pedal is felt, then bleed each caliper (if equipped) until the air is evacuated.
Do you bleed brakes with cap on or off?
Locate your brake master cylinder reservoir’s brake fluid level, usually located under-the-hood. Ensure that your car has the appropriate amount of fluid. While you’re bleeding the brakes, you’ll want to be sure that you leave the master cylinder cap unscrewed but rest it on top of the reservoir.
Is there a special way to bleed ABS brakes?
In general, whenever you are bleeding an ABS-equipped vehicle you can do so exactly as you would any other vehicle – stroke the pedal to pressurize the system, open a bleeder, close the same bleeder, and repeat. This does not change whether you are pressure-bleeding, vacuum-bleeding, or manual-bleeding.
