My Bronco is currently running factory front Disc Brakes along with Explorer Rear Disc Brakes on a new Currie 9" Rear. I have found that the stock Vacuum Boosted Hydraulic System still has much to be desired in such a heavy truck, especially with a performance engine.

My research has determined that a stock Vacuum Boost Brake System operates at approximately 500 psi and a Hydro Boost Brake System operates at approximately 800 psi.

Then I started looking at the Electric Boost Braking Systems by ABS Power Brake. These system are a high end upgrade for performance Hot Rod builds and heavy trucks. They operate with a high pressure electric pump, to an accumulator and Master Cylinder at a pressure of 1600 psi working to 2400 psi max!!! No engine vacuum is used and the existing Brake Booster or Hydro Boost is removed. The new Master Cylinder mounts directly to the firewall, (or remotely if desired), and the Electric Pump and Accumulator can be mounted almost anywhere else as long as it is below the Master Cylinder to support the gravity brake fluid feed. Also, the Accumulator allows for a smooth brake application and supports 10-15 full brake applications in the case of electric pump failure.

I was initially worried about the safety of higher pressure in the existing brake system, but FedHill rates 3/16" (.028 wall thickness) brake lines at 3200 psi Max Working Pressure and 17,000 psi Theoretical Bursting Pressure. And quality flexible stainless steel brake lines are rated approximately 4000 psi Max Working Pressure and 13,000 psi Bursting Pressure.

ABS Power Brake will set up this system custom to the vehicle and the install appears fairly straight forward. It only has two hydraulic connections, the gravity feed from the reservoir and the high pressure assist line that gets plumbed back to the port on the master cylinder with the accumulator inline. The integral pressure switch and relay come pre-wired, requiring only a ground, a battery connection and a keyed ignition connection.

Does anyone have any experience with an Electric Boost Braking System? If you have experience, what are your thoughts?

See this link for a video of Stacey David on the ABS Electric Boost System.

I know this is once again overkill, but that hasn't stopped me before... :toothless

I would think the line ( metal ) would handle those pressures. We use metal lines when in the military and I know most of these line pressures where in 3-9K psi range. Where I would worried at is in any rubber coat wheel line and brakes porportioning between front and back.

Have you not considered the hydraboost? I have a 97 F250 install in place and it is great and the brakes are tighter than 1day old virgin. I don't think you need anything higher than that for our FSB trucks,

Neato! I wonder what kind of amp draw the pump pulls? Also wonder what kind of reliability record the pumps have.

More than anything else, I wonder how the cost compares to the $$$$ JBG Hydroboost kit. Watchin' this with interest...

Thats cool. I'm just upgrading to 1 ton brakes though. If they can stop 15K worth of truck and trailer, they can stop your 6K truck

Looks cool and I bet the price is .....not so cool.

It's overkill, I wouldn't want to run those pressures, and my bet would be that it's not as reliable as a simple vacuum booster set-up.

I got great brakes with disks front and rear, but it took a larger bore master cylinder (1 3/8") and the larger F250/350 vacuum booster. This on the 6,000lbs Carcass on 40's.............................................

I am reading quality braided hoses burst at approximately 12,750-13,500 psi, which is triple that of the 4,250 psi required by the standard for this type of hose. By comparison, the quality OE rubber lines burst at 8,000-9,000 psi, with a recommended safe working pressure of 3,600 psi.

14 amps, at maximum pressure. ABS states that they have been selling these since 2002 with great reliability. They do offer a seal rebuild kit.

JBG Hydroboost Kit is approximately $800.00. The ABS Electric High Power Brake System is $1150.00, and the ABS Electric Dual Power Max (Hydroboost replacement with 45% more power) is $975.00.

At 8 3/4" long, it is also very efficient on space.

Go look at a 89 thunderbird that accumulater and pump looks just like my son's.Only thing that looks different is the mc. And his pump was almost 800.00

Is there any electronics in that thing? Or just an electric pump controlled by a pressure switch? I'm building a non electronic truck with a deisel. It would be nice not to have a vacume pump.
Nope. Just an electric pump with an integral pressure switch and a relay which maintain volume and pressure in the accumulator.

ABS states that it works great with engines having aggressive camshafts, superchargers and turbochargers due to not requiring vacuum.

Go to a pick and pull. Pull ALL the hydroboost stuff from a Ford Diesel. Sand blast and pain everything, install a new master cylinder, and you've got a new setup for a couple hundred $$$$

Comparing the JBG price isn't a good comparison because of how cheap it can be done if you try.

Thanks. Couldn't seem to find a price on their site.

The low draw and space requirements make it a pretty attractive option.

With 2-3x the pressure of a hydro boost setup (and ~3-5x stock brake setup!), are you at all worried about the ability of the stock size ford rotors (granted, you have 4 of 'em) to absorb the additional heat from the greater clamping force in say a quick stop from high speed (80-20mph) without warping? I plan on it someday myself, but you might want to consider bigger rotors and better calipers (esp. front) to work well with that kind of awesome brake operating pressure.

They is pretty, I always liked look of the 10 hole Alcoas on the late trucks. I opted to go 17 and a little wider for a less balloon-y sidewall on 35s and to accommodate certain brake project dreams.

Started w/ steel 17x9s and ended up switchin' to Lightning 17" alloys, because big honkin' steel wheels are HEAVY!

I am picking up a hydro booster in the next month or so to put in place of my old vacuum system. As far as what I have into the swap price wise, I spent $25 on the used booster from a junk yard (master cylinder and push rod were gone already :'( ). It had all the hoses and fittings to bolt on, and was in good shape, except that someone stomped on the brake pedal with the master removed and it all but shot the piston out the front and seized it. A remaned booster is 189.99 from autojunk (only place I priced) and the core is 57.00. So 157.99 for the booster and hoses. I bought the push rod and spring from Vanco over in Cali (800-256-6295) for $40 shipped to my door in a day. I also bought enough brake line and fittings to redo my entire truck for about $100. Add another $50 for the last hoses I need and it comes out to $347.99. Now that does leave me with a stock master cylinder, but I have stock brakes for now and I will worry about changing it when I go SAS (Already got my 79' D44!).

Seems like he received an early model, possibly used and not complete. Clearly, he had to fab a lot of parts.

The new ABS Systems come with everything and are designed for your specific application and vehicle. They were the hit of the recent SEMA Show and sales have been overwhelming for them. I have also read many reviews (Cobras, Mustangs, Lightnings, Off Roaders, Rods) where the installer was most impressed in all areas, especially braking.

It is an out of the box concept which is unconventional. I read if we all think alike, we will not think at all... I think electro boost is very cool and I am eager to try something unique and different. :thumbup
