What is the bleeding sequence for Chevy brakes?

The quickest answer: bleed in this order — right rear, left rear, right front, left front. This farthest-to-nearest sequence is standard for many Chevrolet models and helps purge air efficiently from the system.

Brake bleeding on Chevy vehicles can vary by model, year, and whether the car has an anti-lock brake system (ABS). This guide covers the typical non-ABS sequence and outlines ABS considerations, along with a safe, step-by-step approach to performing a bleed. Always consult your owner’s manual or a GM service manual for model-specific instructions.

Standard bleed order for most Chevy models

To start, use the wheel farthest from the master cylinder as the first bleed point, then progress diagonally toward the wheel closest to the reservoir. On most left-hand drive Chevys with the master cylinder at the driver’s side, that means bleeding the rear wheels first, then the front wheels, in this order:

• Right rear (RR)


• Left rear (LR)


• Right front (RF)


• Left front (LF)

Concluding: This RR-LR-RF-LF sequence is the standard baseline for many Chevrolet four-wheel brake systems without specialized ABS procedures. Verify against your model’s specific service documentation if you encounter differences.

Step-by-step bleeding procedure (two-person method)

Below is a typical two-person bleed procedure for four-wheel disc brakes. It assumes a conventional system without requiring a special ABS-cycle procedure. Gather the right tools and brake fluid before you begin, and keep the reservoir topped up during the process.

1. Prepare the vehicle: Park on level ground, engage the parking brake, chock the wheels, and open the hood to access the brake fluid reservoir. Confirm you’re using the correct DOT brake fluid for your model.


2. Attach bleed hardware: Connect clear tubing to the bleed screw of the first wheel (RR) and submerge the tube in a catch container partially filled with clean brake fluid.


3. Bleed the first wheel: Have a helper slowly pump the brake pedal several times and hold it down. Loosen the bleed screw a quarter to a half turn to allow fluid and air to escape, then retighten before the helper releases the pedal. Repeat until the fluid runs clear of bubbles.


4. Proceed to the next wheel: Move to the LR and repeat the bleeding process, keeping the master cylinder reservoir topped up between wheels.


5. Finish with RF and LF: Continue bleeding in the standard order (RF, then LF) until each wheel shows clear, bubble-free fluid and the brake pedal begins to feel firm.

Concluding: After all four wheels are bled, test the brake pedal with the engine off to verify firmness, then perform a cautious test drive in a safe area. Refill and dispose of old brake fluid according to local regulations.

ABS considerations for Chevy models

Many Chevrolet vehicles equipped with ABS require special attention beyond the basic bleed sequence. If the car has an ABS pump and modulator, you may need to perform an ABS bleed using a diagnostic tool to cycle the pump or follow a manufacturer-specified ABS bleed procedure. In some cases, a simple four-wheel bleed won’t remove all air from the ABS module. Always check the unit’s service manual for model-specific steps, and consider professional service if you’re unsure.

Safety notes and disposal

Brake fluid is corrosive and harmful to skin, eyes, and vehicle paint. Wear gloves and eye protection, avoid spills, and keep the reservoir cap off only as needed. Use the correct DOT specification for your vehicle and dispose of used brake fluid at an authorized facility.

Summary: For most Chevy brakes, bleed in the order RR → LR → RF → LF, starting from the wheel farthest from the master cylinder and working inward. If your model includes ABS or other advanced modules, consult the service manual for an ABS bleed procedure. Maintain fluid levels during the process and verify pedal firmness afterward with a cautious test drive.

Summary

Chevrolet brake bleeding generally follows a farthest-to-nearest sequence (RR, LR, RF, LF) for standard four-wheel discs. ABS-equipped models may require an ABS-specific bleed procedure. Always confirm with model-specific manuals, ensure proper safety practices, and perform a final pedal test to confirm proper brake feel.

How to bleed brakes on a 2002 Chevy Silverado 1500?

To bleed the brakes on a 2002 Chevy Silverado 1500, you will need a partner and the correct brake fluid. Safely lift and secure the vehicle, remove the wheels, and fill the master cylinder with new fluid. Working from the passenger-side rear wheel to the driver-side front, have your partner pump the brake pedal, open the bleeder screw to release air and old fluid, and close the screw when a steady stream of clean fluid appears.
 
Before you begin

• Ensure you have the correct type of brake fluid (check your owner's manual, likely DOT 3). 
• Securely lift the vehicle on jack stands and remove all four wheels. 
• Fill the master cylinder reservoir with new brake fluid, leaving the cap loose but on top. 
• You will need a partner to pump the brake pedal. 

The bleeding process

1. Work from the furthest wheel to the closest: Start with the passenger-side rear wheel, then the driver-side rear, the passenger-side front, and finally the driver-side front. 
2. Attach a hose: Connect a clear plastic or rubber hose to the bleeder screw on the caliper and place the other end into a collection container. Some suggest submerging the end of the hose in a small amount of new brake fluid in the container to prevent air from being sucked back in. 
3. Pump the pedal: Have your partner pump the brake pedal several times until it feels firm and then hold it down. 
4. Open the bleeder screw: With the pedal held down, open the bleeder screw (usually by turning it counterclockwise) about a quarter turn. Fluid and air will be pushed out. 
5. Close the screw: When the pedal reaches the floor, immediately close the bleeder screw. 
6. Repeat until clean: Repeat steps 3-5 until you see a steady stream of clean fluid with no air bubbles coming out of the hose. 
7. Continue to the next wheel: After the last wheel is bled, have your partner press the pedal one last time to check for firmness. 

Finishing up

• Once all wheels are bled, top off the master cylinder reservoir to the "max" line. 
• Reinstall the wheels and torque the lug nuts to the manufacturer's specifications. 
• Perform a road test to ensure the brakes are working correctly. 
• If the system has an ABS module, you may need to perform a specific procedure after manual bleeding, which might involve a special scan tool to cycle the ABS pump to clear any remaining air. 

What is the correct order to bleed your brakes?

The standard brake bleeding sequence is to start at the wheel farthest from the master cylinder and work your way closer: right rear, left rear, right front, and finally left front. Always check your owner's manual to confirm the correct sequence for your specific vehicle, as some systems with ABS modules may have a different order, and periodically top off the master cylinder to prevent air from entering the system.
 
Standard brake bleeding sequence (for most vehicles) 

• Step 1: Right rear wheel (passenger side)
• Step 2: Left rear wheel (driver side)
• Step 3: Right front wheel (passenger side)
• Step 4: Left front wheel (driver side) 

Important considerations

• Check your owner's manual: Some vehicles, especially those with rear-mounted ABS modules, may require a different sequence. 
• Top off the master cylinder: Keep the brake fluid reservoir full throughout the process. If it runs dry, you will introduce air into the system and have to start over. 
• Work with an assistant: Have one person operate the brake pedal while another opens and closes the bleeder valve at each wheel. 
• Close the valve: Make sure to close the bleeder valve before the person pumping the pedal releases the pedal, notes this YouTube video and Brakes-shop.com article.

How do you bleed GM brakes with ABS?

To bleed a GM ABS system, you'll likely need a professional scan tool to activate the ABS solenoids while you manually bleed the brakes at each wheel. The general procedure involves using the scan tool to run the automated bleed process, which will cycle the valves, followed by a manual bleeding process (typically starting with the right rear wheel) to purge the air. After manually bleeding all four wheels, repeat the scan tool's automated sequence to ensure all air is purged and the pedal feels firm.
 
Using a scan tool

1. Connect: the scan tool to the vehicle's OBD-II port. 
2. Navigate: to the "ABS Bleeding" or "Automated Bleed Procedure" function in the tool's special functions menu. 
3. Follow: the scan tool's prompts. This will involve turning the ignition to the "on" position but not starting the engine. 
4. Allow: the scan tool to activate the ABS pump and solenoids. This is a crucial step to push trapped air out of the ABS module. 
5. Manually bleed: the brakes at each wheel as the scan tool directs you. The typical sequence is right rear, left rear, right front, and left front. 
6. Open: the bleeder screw at the wheel you're working on, and pump the brake pedal until it's firm. Close the bleeder screw before the pedal goes to the floor. 
7. Repeat: the process for all four wheels, ensuring you keep the master cylinder reservoir topped off to prevent new air from entering the system. 
8. Follow: the scan tool's instructions to end the process after the manual bleeds are complete. 
9. Test: the brake pedal for a firm feel and proper function. 
10. Check: for any diagnostic trouble codes and clear them if necessary. 

Without a scan tool (less effective for air in the ABS module) 

• Bleeding the brake lines without a scan tool to activate the ABS pump may be insufficient if a significant amount of air has entered the ABS module itself. 
• A traditional two-person bleeding method (or a pressure bleeder) can be used to bleed the brake lines, but this may not remove all the air from the ABS hydraulic unit. 
• For some systems, after the manual bleed is complete, driving the vehicle above 333 mph will allow the ABS controller to reset and push some air out. You may need to re-bleed the brakes if the pedal still feels soft.
