"Your Speedi-Bleed is amazing and light years ahead of other brake bleeder tools...it's a real winner, my students love it and so do I.”

"Simple, fast hookup and works great. I spent a lot of years twisting wrenches in dealerships before changing careers, and Speedi-Bleed is the best pressure brake bleeder I've ever used.”

How To Bleed Brakes
- Speedi-Bleed Instructions
- Bleeding Master Cylinder
- Bleeding ABS Brakes
- Proportioning Valves
- Speedi-Bleed Usage Tips
|STEP 1|| Remove master cylinder filler cap
|STEP 2|| Attach Speedi-Bleed adapter to brake reservoir
Correct adapter - see "Find Your Brake Bleeder" (left sidebar)
|STEP 3|| Fill Speedi-Bleed bottle with fresh brake fluid
Firmly re-tighten bottle cap after filling bottle.
|STEP 4|| Connect bottle air hose to tire
* Pro Kit: push air nozzle onto stem and twist clockwise 1/3 turn
* Make sure bottle gauge reads 0 psi: adjust regulator if needed.
|STEP 5|| Connect bottle fluid hose to adapter
Push bottle female coupler onto adapter male coupler.
|STEP 6|| Set working pressure
Starting with 0 psi, slowly adjust regulator to 10-15 psi
|STEP 7|| Open bleeder screws
Open each caliper / wheel cylinder bleed screw for 10-15 seconds, or until fluid is clean and bubble free. A clear hose and catch container can be used collect the old fluid.
NOTE: 4 wheel brake bleed will typical result in only 1-3 psi tire pressure loss
Speedi-Bleed removal procedure
1. Adjust air regulator down to 0 psi
2. Remove air hose from tire
3. Disconnect fluid hose from adapter
4. Remove adapter from master cylinder reservoir
5. Replace master cylinder filler cap
Bleeding Master Cylinder
Another advantage of using Speedi-Bleed is the ability to perform fast, effective on vehicle bleeding of the master cylinder.
• Hookup Speedi-Bleed tool
NOTE: The brakes can usually be bled without first bleeding the pre-installed master cylinder, but a firmer pedal typically results if the master cylinder is fully bled before opening the bleeder screws at each wheel.
Bleeding ABS Brakes
Most vehicles with ABS brakes can be bled as normal without any additional procedures or tools required. Simply hookup Speedi-Bleed and open the bleeder screws. Job done. Exceptions do exist though:
1. If air has entered the ABS hydraulic unit **
** master cylinder reservoir runs dry
** ABS hydraulic unit removal / replacement
B. A workaround method can provide satisfactory results, by first bleeding the conventional brake circuit via the wheels, followed by activating the ABS during a test drive on vacant parking lot or back road. An attempted wheel lockup is required by slamming hard on the brake pedal. This will open up the ABS hydraulic circuits and release trapped air into the conventional or base circuit. The brake system is then re-bled at the wheels.
The downside with this method, is that the time duration that the ABS circuit will be opened will be much less than with the scan tool method. Repeated applications of "bleed, ABS stop, bleed" could be needed to obtain desirable results.
NOTE: Caution should be used if attempting this procedure. Only proceed if safe to do so, and be aware that the brake pedal could suddenly drop when the air is released from the ABS system into the wheel circuits. Vehicle speed of 6-10 mph minimum is typically required to activate the ABS system during an anti-lock application
2. Kelsey Hayes EBC-4 ABS system used on late 1980's to mid 1990's GM trucks
3. Integral ABS
Integral ABS can typically be bled by running the ABS pump and using the pressure stored in the ABS system to bleed the rear wheels, combined with conventional methods to bleed the front wheels.

Teves MK II
In order to pressure bleed some 1960's to 1980's brake systems, the proportioning valve will need held open. This is done by either pushing in or pulling out the valve stem.
Speedi-Bleed Usage Tips
First time usage:
A dry run is recommended. This involves hooking up tool and setting the working pressure without any brake fluid in bottle, in order to get a feel for tool operation., while checking brake reservoir / adapter for any sign of air leaks
Apply brake fluid to adapter o-ring seal (C500, C600 adapters)
Rub brake fluid around rubber o-rings. This will aid with sealing and make the C500/C600 adapter fit into filler neck more smoothly.
Tighten wing nuts evenly and firmly (C100, C200, C300 adapters)
Higher working pressures can be obtained if care is taken to center the adapter over the master cylinder reservoir, and the wing nuts tightened properly. When the C100 or C300 adapter is removed from the reservoir, you should see an indentation pattern on the adapter rubber gasket. This will indicate the gasket has "bitten" into the filler neck and good seal was formed.
Connecting tire nozzle fitting to tire (Pro Kits)
Squeeze tire nozzle lever, push tire nozzle onto tire valve, release lever, and twist nozzle about 1/4 turn to seal
Setting working pressure
Always start with 0 psi and slowly increase pressure.
The wheel sequence of furthest to closest (RR, RL, FR, FL) is most commonly used, and will work fine on the majority of vehicles, but whenever possible the manufacturers stated bleed sequence is recommended.
Storing pressure bottle
If Speedi-Bleed is used infrequently, remove brake fluid from bottle before storing.
Cleaning pressure regulator
If brake fluid has entered into regulator it can be typically removed with simple procedure. With no fluid in pressure bottle, connect tire nozzle to tire. Adjust regulator to 10-15 psi and then back down to 0 psi. Repeat a few times. This should blow any fluid inside regulator out of the relief hole.
