Yes! The vast majority of vehicles with ABS can be pressure bled without any additional procedures or scan tool required,
provided no air has entered the ABS system. If air has entered the ABS side of the brake system (typically from ABS modulator
or master cylinder removal, or the fluid reservoir running empty), a scan tool could be required to fully purge the ABS circuits.
A workaround method can work. First bleed conventional brake circuit as usual, next activate ABS system during test drive
by locking up the wheel(s), and then re-bleed the brake system. Repeated applications of bleed, drive, bleed, might be required
to obtain desired results. Only perform this procedure at slowest speed possible. A secluded location, such as back road or vacant
parking lot should be used. Wet or loose surface, such as dirt or gravel would be optimal.
No, Speedi-Bleed effectively removes air bubbles, it does not add more. The manual “two person” brake bleeding method
poses a higher risk of creating cavitations and air bubbles, especially if the brake pedal is operated in an overly vigorous manner.
The tire provides a safe, large volume of clean air that can be quickly and easily regulated using the inline Speedi-Bleed
pressure regulator. Unlike an air compressor, the tire does not necessitate a water filter / separator, or concern over too
high pressure. Hand pump operated pressure bleeders can need re-pumping to build back the pressure drop during the
bleeding process. Speedi-Bleed provides a constant air source, setting the working pressure once to 15-20 psi will be
enough to complete the bleed procedure.
Note: A complete 4 wheel brake bleed will typically result in only 1-3 psi tire pressure loss.
10-15 psi will work well for most vehicles. Higher working pressures of 25-30 psi will provide faster fluid flow from the bleed screws,
especially at the rear wheels. Always start from 0 psi and slowly increase working pressure with inline regulator, while stopping
periodically to check for any leaks.
Note: Certain ABS systems can require higher working pressures, example early Kelsey Hayes used on GM vehicles
can require 30-32 psi in order to effectively bleed.
