Electric master cylinder??

[Loonytoon]

has anyone had any experience with electrically boosted master cylinders?

My roadrunner has no booster and drums all the way round and I want to do a front disk brake conversion but can’t be bothered fitting a booster and vacuume canisters to compensate for the camshaft.. looks like it will be easier to run an electric master but haven’t heard much about them.

Thanks.

....OR you use a master cylinder without a booster.

That’s what I’m running now.. I want assisted brakes.

Maybe you just need to fine tune what you have.
A different bore size master cylinder. Maybe an adjustment to the pedal ratio?
I took a spare brake pedal assembly and drilled a hole above the stock hole. This increased the pedal ratio....meaning that the master cylinder pushrod moved faster for the same amount of pedal movement. It made a noticeable difference.
I have never heard of electric boosted hydraulic brakes. Locomotives may use them but cars are far simpler.
I'm unsure why you want to try something so far off the beaten path as compared to a factory proven system that you can order right this minute.

Because if I run an electric brake booster I can do away with ugly booster and vacuume canister and it will look a lot neater and easier to fit up.

These are not a new concept they have been around for many years. I’m just curious to see if anyone has fitted one to their mopar with succes.

WEll, I do wish you luck. I have never seen a Mopar with it but we are often behind the curve. It took our guys almost 20 years to start building rear wheel drive cars and V8 engines in cars again so we have some catching up to do.

Watch this video before any considerations of going electric

If you want to go that route why an electric master? Totally electric brakes have been around for years.

There was a car on Fathom Works just last week that they installed electric power brakes on. They did not have room in engine compartment for a vac booster.

I just converted my 70 Satellite from front drums to discs with an SSBC kit and used a Right Stuff Manual Master Cylinder with 15/16" bore. The pedal is very easy to engage, not really much harder than my modern daily drivers with power/abs brake systems. Car stops great too. Before spending a ton of money on the electric booster, I would convert the fronts to disc and install a 15/16" manual master. See how that feels. Just my 2 cents.

interesting, has anybody put the bigger master on drum /drum and noticed much of a difference in stopping .

 

[Kern Dog]

Is that a question ?

 

[towtruckAl]

its a question dont know any other way of wording ...

 

[Kern Dog]

Questions have question marks at the end my friend!

 

[towtruckAl]

Ok so now you know its a question what is your answer !!

 

[Kern Dog]

Hey....You forgot the question mark again! Post #15. You forgot the commas too.
Are you okay up there? Maybe you bought the keyboard at a discount and a few keys don't work?
I don't see the value in this idea. A non power master cylinder works great as long as the pedal ratio is favorable.

Just noticed your post and maybe you answered my question. I know it sounds simple and too easy of a fix, but can I just remove the booster on a power disc/manual conversion kit, leave every thing else the same - pedal ratio, proportion valve, master cyl size - and end up with good brakes, or am I missing something.

I'm in the same boat as you about six months later now and I see no one has answered that post yet what did you end up doing
