How to Use a One-Man Brake Bleeder Kit
One-man brake bleeding is most often accomplished using a hand-held vacuum pump to draw air out of the brake system. While the air is drawn out, new brakefluid is drawn into the system using the pump.
Difficulty: Moderate
Instructions
Things You'll Need:
• Jack
• Jack stands
• Lug wrench
• Torque wrench
• Metric or SAE box end wrench set
•Brake fluid
• Vacuum bleeding kit
Secure the Vehicle
1. 1
Jack the car up using a sturdy jack and secure it on jack stands that are properly rated for the weight of your vehicle. Be sure you areon firm, flat ground so the jack stands won't shift.
2. 2
Remove the tires using a properly sized lug wrench. Set the tires and lug nuts aside.
3. 3
Remove the master cylinder reservoir cover andset it aside. If the fluid is low, top it off with new brake fluid before starting to bleed the system.
Bleeding the Brake System
4. 1
Attach the hose from the vacuum bleeder to the brake-bleedingnipple at the brake drum or caliper farthest from the master cylinder first.
5. 2
Open the bleeder screw with a properly sized box end wrench. The screw may be tight, so be sure the wrench fitsproperly to avoid stripping the hex on the screw.
6. 3
Pump the vacuum pump slowly, watching the fluid coming through the tube. When all the air bubbles are gone and you see clean fluid coming out, closethe screw securely.
7. 4
Move to the next brake drum or caliper and repeat the procedure. Continue around the vehicle until all four brakes have been bled. Do not let the brake fluid level in thereservoir fall below 1/4 at any time during the bleeding process as air may be drawn back into the system.
8. 5
Replace the wheels and tighten with the lug wrench. All four wheels should be torquedto the manufacturer's specifications for maximum safety.
9. 6
Check the brake fluid level in the master cylinder reservoir and top it off as needed. Replace the reservoir cover and remove the jack...
