ECI Brake Pressure Multiplier---Anybody tried this thing?

[RECHRGD]

I just saw these advertised in a Good Guys magazine.  Does anybody have any experience with them.  It looks like it could be just what the doctor ordered for those of us that went the S.S. Brakes Co. front disc manual conversion kit route, and now have to apply way too much pedal pressure to make our cars stop quickly.  Go to www.ecihotrodbrakes.com   Thanks, Bob

I have no experience with the force mutiplier mentioned, but I have used their Disc Brake Conversion kits with outstanding success, no problems whatsoever. It appears that the multipliers are built to your particular needs... so I would contact "Ralph" at hotrodbrakes@sbcglobal.net ... he is the Engineer/Owner of ECI and would be able to answer all of your questions.

It might be cheaper to buy a master cylinder with a smaller diameter bore, if you want to increase line pressure.

Yep, that's the way I'm going.

The catalog thingy sounds like the same kind of basic compromise as a change in the existing brake/master cylinders:  lengthen the pedal throw to gain fluid pressure.   



But with that new thingy, the ad is suggesting that it's doing more at maximum pressure somehow.  I dunno what it would do exactly. 

If it truly differentiates its action between low pressure & higher pressure, then that might still be a very useful item. 

I would think it would be most useful on a system that's already a short-throw pedal setup with a normal vacuum booster. Those early vacuum-assisted factory brake systems can grab so abruptly.  The new thingy might help the driver modulate the pressure better at near-lockup.

In some installations the increased pedal travel from the smaller MC just isn't acceptable, I have been looking at this electric MC but the price has me stopped:

Why not just get a normal vacuum booster and be done with it?  Works fine and doesn't cost any HP or amps at all.

Do you have valvecover clearance issues or something?

There are some cases where a traditional vacuum booster just won't fit physically nor suit the surroundings.

I could use a raised booster bracket ala Hemi or A body but it just wouldn't look right in these surroundings.
