Sounds like a cool idea... but just make sure you have a mechanical emergency brake while you're testing it. Or atleast a hole in the floor you can jam a stick through to slow you down.
It may or may not work...I'm one who believes that most anything can be done with the right amount of thought and work...and this is probably one.. But, if you don't want anything on the firewall you could simply mount it under the floor in typical hotrod fashion. Granted, room is an issue there as well with clutch hardware (if a manual is uses) exhaust etc...but it works and is proven... I'm also not one for reinventing the wheel i guess and a bit boring when it comes right down to it
Did that on my T. Cad master in the trunk operated by a fruitjar on the firewall. Used a Honda clutch cylinder for a slave. Works good. Been in place for two years, no problems. Pedal feel is just like power brakes.
If the slave cylinder or the single res master cylinder or lines leak or break in any way, your remote mounted Dual master in the truck bed is useless. I think this is as unsafe as a single master setup, or even more unsafe because of all the extra components, more stuff to go wrong. Just my 2 cents worth.
Seen it done, my two cents is to make the connecting rod between pedal and master cylinder a pulling affair via a pivot instead of a compresion link.........
What he said, make it ALL mechanical and keep the flexing to a minimum. It'll work! Of course, it won't be as easy as routing a hydraulic hose.
It's a clever idea, but not a smart one. Devise a mechanical linkage if you need to remotely mount the master cylinder.
I don't consider single masters unsafe. Millions of cars were built with them and most never had a catastrophic brake failure.
yep, more to go wrong... single point of failure ditto... I've seen plenty in the last 10 years or so. a lot of them are older ones, and I chalk this up to that, but I still believe a properly set up dual master is way safer than a single.
The purpose of the dual master is to add some redundancy in the event of a failure. To run said master with a hydraulic system kind of makes that pointless. Sure, singles don't always fail, I drove a long ways with one myself - but sometimes they do, like the Dodge I saw someone crash into the brush last week - and I'd rather have a big ugly master on my firewall that I know works like it's supposed to, than take a chance. Of course if you're only going to drive this thing on the show grounds and trailer it back and forth, that's another story.
do it. all the parts are brand new free from corrosion so a line to blow is highly unlikely . clutch cylinders last for thousands of miles before wearing out make sure you have an E brake
why not put the whole **** under the dash? take a lil fabrication to work, but its all stuffed out of sight and its all mechanical too. kugel makes a pretty slick setup too... kugel brakes
A rep stopped in yesterday with a remote mount master and booster. Mounted wherever and used a very small actuator if you will on the firewall. Worked just like a big rig brake if it lost air preasure it would apply the brakes with spring preasure in the booster. May work for your aplication but I believe in the Kiss method also.
There is a guy in town here that has a mid 50's Chevy pickup with a 440 Chrysler engine and a set of long ram intake manifolds.There was no room at all under the hood for a master cylinder/booster setup so he mounted it in the front of the pickup bed.Not sure what he used for components(I can ask him)but it has been together about 8 or 9 years that I know of and he's had no problems.
I never thought those were a good idea. Fluid leaking on your feet and carpet with an "ill" sealing lid. And oh so hard to check the level, and forget about trying to add fluid. Find a decent looking master and put it on the ****ing firewall where it belongs.. Are you guys building Hot Rods or Street Rods?
For what it's worth......Chrysler Australia used a similar setup in the A-bodies with the slant six. Due to the cars being right-hand drive, and the engine leaning to the right, there was minimal room for a boosted master on the right side of the firewall. What they did was to leave the main boosted master on the left, mount a tiny master on the right, pressurizing a small cylinder mounted to the back of the boosted master. With that setup, the driver applying brakes would then actuate the small cylinder, which would in turn actuate the boosted master, applying the brakes. I'm sure it worked reasonably well, but I have to side with the KISS principle. More complexity to a system just gives that system more maintenance and potential breakage/failure. I might suggest a push-pull cable instead of a hydraulic actuater. Roger
As my old man says, "Anything is possible given enough time and money, but is it worth it?" I was thinking of this setup - eliminates one of the failure points.
