Brake Pressure Bleeder
Frequently Bought Together
Frequently Asked Questions
The AGM Brake Pressure Bleeder helps you bleed and flush brake systems using controlled positive pressure at the master cylinder reservoir.
Instead of relying on the old two-person pump-and-hold method, the bleeder pushes fresh brake fluid through the system so old fluid and air can be removed at each bleeder screw.
Because brake bleeding is cleaner, easier, and more consistent when controlled pressure does the work.
The AGM Brake Pressure Bleeder lets one person service the brake system without waiting for a helper, fighting the pedal, or paying for every brake flush at a shop.
Add brake fluid to the 3-liter tank, connect shop air, set the pressure with the built-in regulator and gauge, and connect the correct master cylinder reservoir adapter.
Once connected, open the ball valve to send controlled pressure into the brake system. Then open each bleeder screw to flush old fluid and air into the catch bottle until clean fluid comes through.
Yes. That is one of the main benefits of the AGM Brake Pressure Bleeder.
Once the system is filled, pressurized, and connected with the correct adapter, one person can bleed each corner without needing someone else to pump and hold the brake pedal.
Yes, the AGM Brake Pressure Bleeder can be used on many vehicles equipped with ABS and traction control.
Positive pressure is the same method many professional shops use, but some vehicles may still require manufacturer-specific procedures, scan-tool cycling, or special steps. Always follow the proper service procedure for your vehicle.
Positive pressure applies steady pressure at the master cylinder reservoir, helping move fluid through the brake system in a controlled way.
That can make the job cleaner and easier than relying on pedal pumping, especially when working alone or flushing old fluid through modern brake systems.
The AGM Brake Pressure Bleeder works with an air compressor.
Use the built-in adjustable regulator and pressure gauge to set and monitor pressure before and during the bleeding process. NOTE: empty your compressor tank of moisture and turn down your compressors regulator to just above the pressure needed for the bleeder, before you start your brake bleed.
The AGM Brake Pressure Bleeder has a 3-liter capacity.
That gives you enough fluid capacity for most brake bleeding and flushing jobs without constantly refilling the tank.
The AGM Brake Pressure Bleeder includes:
- AGM Brake Pressure Bleeder
- Catch bottle
- Syringe
- Filler cap removal wrench
No. Master cylinder reservoir adapters are sold separately.
Reservoir designs vary widely between vehicles, so adapters are not one-size-fits-all. Selling adapters separately lets you buy the adapter that fits your vehicle instead of paying for parts you do not need.
Choose the adapter that fits your vehicle’s master cylinder reservoir.
If you are unsure, check the adapter product pages, compare your reservoir design, or contact AGM before ordering so we can help point you toward the correct option.
No. You need the correct master cylinder reservoir adapter to connect the bleeder to your vehicle.
The adapter creates the sealed connection needed to apply pressure to the brake system.
No. The AGM Brake Pressure Bleeder is used by pros, DIYers, racers, and home-garage users.
It is designed for mechanically capable users who can read and follow brake-service instructions and want a cleaner, easier way to bleed brakes.
Yes. Brake service is safety-critical.
This tool is designed for mechanically capable users who can read, understand, and follow the included instructions and proper brake-service procedures. If you are unsure about the process, consult a qualified mechanic before servicing your brakes.
Yes. The AGM Brake Pressure Bleeder can be used to flush old brake fluid from the system and replace it with fresh fluid.
Always use the correct brake fluid for your vehicle and follow the proper bleeding sequence and service procedure.
Yes. The AGM Brake Pressure Bleeder can be used after replacing parts such as calipers, wheel cylinders, brake lines, and other brake-system components.
Some repairs require additional steps before pressure bleeding. For example, if you replace the master cylinder, it must be properly bench bled before using the Brake Pressure Bleeder on the vehicle.
Always follow the correct service procedure for the parts you replaced and the vehicle you are working on.
Follow the recommended pressure range for your vehicle and brake system. - The Bleeder works best between 8-15psi. If additional pressure required, consider other options.
The AGM Brake Pressure Bleeder includes a built-in adjustable regulator and pressure gauge so you can set and monitor pressure during use.
Brake bleeding can be messy, but the AGM Brake Pressure Bleeder is designed to make the process cleaner and easier to control.
The included catch bottle helps collect old fluid at each bleeder screw, while the positive-pressure setup reduces the back-and-forth of the old pump-and-hold method.
Yes. The AGM Brake Pressure Bleeder is covered by AGM’s Lifetime Shield.

Highly effective brake bleeding tool that enables one-person operation, praised for making brake work "quick and easy." Customers report "rock hard pedal" results and time savings. Most love it, though some experienced cap warping issues after multiple uses and a few had compatibility challenges. Note: universal adapter sold separately but recommended.
Really good for my 2003 bmw e53
Just used it the first time to replace all the fluid and damn this made the job easier! Replaced all the fluid and no air in the system, even got rid of the spongy GM brake peddle!
I used an inline pressure regulator for added safety and usability.
My only complaint is the 60mL syringe came cracked down the side but I had a smaller on on hand to draw out he excess fluid from the reservoir.
Todd, thanks so much for sharing your experience! Sounds like the setup worked great - glad to hear it made the job easier and got that GM pedal feeling right again. Smart move adding the inline regulator too! Sorry to hear about the cracked syringe, though. We'll get a replacement sent out to you. Really appreciate you taking the time to share your story.
The air/fluid coupler on the output hose is junk straight out of the box, doesn't snap closed to retain a connection. Fortunately I had a spare 99 cent coupler from Harbor Freight that I swapped on and it worked fine. It's really annoying to spend extra to get something from a "quality" source and it be broken out of the box.
This system made bleeding the brakes easier than I could have imagined. Works perfectly. I remember 40 years ago, helping Dad and learning how to bleed brakes. The days of being yelled at by Dad or, using your wife and risking your marriage are over.
Used it 2 times it worked great but then the 3rd time of use the cap was warped and would not seat all the way down and would pop off when pressurized.
Elyan, thank you for letting us know. We just sent you an email to get the bleeder sent back to us, so we can better understand what is happening when you say 'the cap was warped'.
That saying applies here for sure ,, I did new brake lines with my portals on a x3 and tried to vac bleed these
I had already known about the AGM and cap setup from the forums ,, well bleeding was going poorly so bought this kit and 3 days later I had it , 30 min later my brakes were all bled ,, flawless and if you buy a 45* 1/4 npt you can use the AGM fitting with a windshield in place
This is a really nice, durable bleeder. It seems well-made; the plastic is thick and built to sustain some abuse. It isn�t a cheap kit, but it is well made. This kit doesn�t include the reservoir cap adapter, so if you want that you need to order the more expensive bundle or, better yet, grab a complete set of cap adapters. I have another cheaper bleeder in my shop but this one seems like it�s better constructed and will outlast the other cheaper model.
I felt strongly enough to write a review of the AGM products Brake Pressure Bleeder and Brake Reservoir Cap - Universal Adapter. I am very familiar with the traditional method of bleeding brakes through pumping of the brake pedal and opening the bleeder screw. This was always a 2-person job but no more. I used this kit of items on my 2009 C6 Corvette and it worked flawlessly. I did not fill the canister with brake fluid, rather I wanted to fill the brake fluid manually after performing two brakes lines at a time. The universal cap adapter securely fit on the brake fluid holding tank securely allowing the positive air pressure from escaping. Follow the directions and use no more than 12-15 psi in the tank and ensure no leaking through the rubber cap on the tank. Additionally, when using the cap adapter, ensure you route the chain around any brake lines or wires, this is an extremely important step. I hope this gives any car enthusiast the confidence to perform the brake bleeding method by themself in a safe and easy way. This is a wonderful product. And yes, I am an actual customer of this product and very happy with the decision to purchase!
Pressure relief is ok.
I've bought 2 of these kits and the master cylinder adapter kit. I have a fleet of 50-60 vehicles and this kit has become a must have for the shop. Never been easier to do a thorough flush on brake systems.
Works great. Just like advertised. Make sure you get the universal adapter for the master cylinder. It does not come with the machine. But I watched the video and it was simple process. Put in new master cylinder bled them all twice. Worked perfect. Worth every penny.
Best kit in the market, easy to use and operate. Highly recommend.
First time using this kit and it could not be easier.
I can't say enough good things about this product. I was able to bleed my brakes easily, and efficiently by myself. With no air bubbles left in the lines
I've followed the instructions and watched several videos on YouTube and this just doesn't work for me. I even purchased the vehicle specific cap for the reservoir. My son and I ended up bleeding the brakes the old fashion way. I really wanted this to work for me. If someone can help me figure out why this doesn't work I'll give it another try and rate this higher.
Lo usamos mucho en nuestro taller
Easiest to use, one-man brake bleeder I�ve ever used! Hands down best way to push all the air out of a master cylinder replacement, Abs module, all new brake lines and larger calipers. Put 2-qts new fluid in and went thru everything twice. Did it again quickly a week later after driving and got just a few bubbles out of the bigger calipers.My only complaint is the fill cap is temperamental to get the threads engaged straight and you can�t overtighten. Don�t exceed 12psi air pressure input. You will probably need to buy the specific brake reservoir cap for your vehicle too (found my Nissan one on Amazon).
Quick and easy on my can am x3 after replacing brake lines
Is not compatible with Chevy sonic.Had to wrap chain around something else and still didn't work well. It sealed but now my brake pedal is squishy
This is thought out and quality tool. Made flushing my brake system quick and easy.
Didn�t include one of the parts necessary to its use
This is a must have for bleeding brakes Period ! And absolutely necessary if you have a dual master cylinder front - rear where a 3 person bleed would otherwise be required. Super simple to use, I would suggest whatever vehicle / buggy your working on IS Buy another brake master cylinder cap and seal and make a pressure cap very simple I spent more time making the cap than I did bleeding the brakes but Now I have one ! FWIW Good Day !
It is so effective, you won't want to do the "partner pumping the brake" routine again! Some may say that the air bleed leaks. Hello? That is because it is the pressure relief valve! You only need to apply maybe 20psi (?) to the system. If you go over, it just bleeds the air out of the cannister, giving you a safe pressure that pumps fluid through the brake system. I also bought an extensive master kit for brake reservoirs. That has helped a lot. The "universal" adaptor is not one that you should count on. One hint: If you install a new master cylinder, manually fill it first FROM the nipples backwards using an oiler can or syringe. Then don't be afraid to push the brake pedal in a few times while pressure bleeding- it gets that last bit of air to find its way out.
Excellent tool for the very reasonable price. Worked as advertised, no leaks, effectively flushed and bled system as well as much more expensive units.
I did install an inline air regulator to the incoming air supply which allowed totally quiet operation.
The system would be perfect ifyou have a compressor that can handle the constant air that is designed to bypass
My home compressor ( pancake) is too small to maintain the pressure required to make the system work
very disappointed there was no warning that the system requires a larger compressor to work properly
William, we're sorry to hear that your compressor is not able to provide enough air for the bleeder to function. We have not run into this before as most air compressors, even smaller 3 gallon 'pancake' style compressor that we have used at campsites were able to provide 10psi of constant pressure. We just sent you an email asking for details on your compressor, so we can pick one up for testing. Hope to hear from you soon.
My can am maverick r brakes have never worked well. I tried vacuum and manual bleeding them , but never got the feel I was looking for. That changed after pressure bleeding the system.
