Bleeding Without A Pressure Bleeder
NOTE:
Correct manual bleeding of brakes hydraulic system will require aid of a helper.
The following wheel sequence should be used when bleeding brake hydraulic system. The use of this wheel sequence will ensure adequate removal of all trapped air from brake hydraulic system:
- Left Rear Wheel
- Right Front Wheel
- Left Front Wheel
- Right Rear Wheel
CAUTION:
Slightly opening bleeder screw often restricts flow of brake fluid. A slow weak flow of brake fluid from bleeder screw will NOT get all air out.
- Pump brake pedal 3 or 4 times and hold it down before bleeder screw is opened. Push brake pedal toward floor and hold it down. Then open left rear bleeder screw at least 1 full turn. When bleeder screw opens brake pedal will drop all way to floor. Release brake pedal only after bleeder screw is closed.
- Repeat step 1), 4-5 times, at each bleeder screw, in required sequence. This should pass a sufficient amount of fluid to expel all trapped air from brake system. Ensure to monitor fluid level in master cylinder, so it stays at a proper level so air will not enter brake system through master cylinder. Test drive vehicle to ensure brakes are operating correctly and a solid brake pedal has been obtained.
