could i put the front and rear brakes on one pedel for the piranha?
-
Im sure you could. If I were to do it I would hook 2 master cylinders up to one pedal.
-
why not use a small car master, with provisions for front and rear?
-

how would you do that?
-
Many people have already done it. Simply connect the 2 masters to the pedal. the push rods have threads on them so you can dial it in as far as when the fronts and rears engage. I try and find pics of others set ups and post them for your ideas.

k thanks
-
look at the wilwood brakes site for ideas.

You connect the 2 master cylinders with a "balance bar" that way you can adjust the bias between front and rear to achieve the desired braking at each end of the car.
-
What is a "balance bar?" I have heard of a bias control, figured it was just a needle valve or similar?
-
GO to the wilwood site and see

-
You need to look at the pedal assemblies to see info about the dual MC pedals.They use the balance bar.The bias valves you posted are similar in function to the balance bar but they only BIAS the braking function.The difference is that using the bias valves is that you have only one MC.If it fails you have NO brakes.Using a dual MC pedal assembly(you can make it yourself) you have the advantage of the safety of 2 MC's and true biasing/balance front to rear.

:t :m You guys with High speed connections can look it up and post it faster than I can get the page up.I show you WHERE to fish . ;D

Ok, makes sense now....
Floor Mount Dual Master Cylinder Brake Pedal with Balance Bar:
This is one of racing's most popular pedals for mounting two brake master cylinders with a bias balance bar. The pedal features all aluminum frame and arm construction with steel pivots, mounting studs, and an anti-skid pedal pad. Wilwood's clevis and pivot pin balance bar provide smoth and accurate settings of the brake pedal bias. It can be set and locked down with the jam nut, or attached to a remote cable for quick on-track adjustments.

The reason this is of interest to me, is this summer, assuming no other major malfunctions I would like to add front brakes to the ride in case I ever want to run it in the desert....
-
The simple,cheap,effective,most used way is the bias valve.Ultimate safety is the dual MC/balance bar.Your choice.
-
So on a 1000-1500 lbs MC buggy, do you feel front brakes are a good thing, a neccesity, etc? For sand only? I know we threw all the front brakes away on our sand only quads, and tried to keep at least one brain cell engaged.
-
Rear only is fine for sand.I use front and rear tho.
-
Why not just do the brakes like in the Piranha plans.
2 masters with 2 pedals, close together. This way you can bias front or rear by just tipping your foot. It does work nice. They're so close together that you always end up on both pedals. Doug Heim sells a nice assembly than includes the master. Mount these side by side.
Hey Doug, What do I get for the plug? :D

is it better to have a pin like the plans show or the bolts like you have?
-
This idea ROCKS for getting unstuck from the side of a hill! Winner winner! Any down side?

I am not sure the idea behind taking front brakes off a quad. The tiny bit of friction and the meager few pounds of weight saved are not worth the safety lost. I have seen many drag Banshees and others with no front brakes and when some doofus drives across the drag strip in the dunes (It happens a lot at Silver Lake) and the rear brakes locked up with the machine going upwards of 70 MPH and trying to stop before they hit them. Those with front brakes stop MUCH quicker!
I feel that anything with over 45 mph capability and over 350 pounds front brakes are a good thing. Especially on downhills. No front brakes makes for LONG stop times there.
I say run-em.
-
Works the same either way. I used 2 seperate socket head shoulder screws because we stock them at work. I also couldn't run a shaft all the way across. (I had the Air shifter's pressure switch mounted between the pedal boxes.)
I'll probably do my current build with shoulder screws too. I like it better.
Shafts with cotter pins are what they use on my lawn mower deck.
-
IMO, i had a balance bar dual caliper pedal, I thought it completely sucked ass, I would use one maste and a proportioning valve myself, I sell all them pieces Yummi posted pics of as well as a dual master Balance bar pedal, with remote cable...
-
I guess the style you want dpends up what safety factors you require. Im not a fan of the dual pedal dual master cyl idea. This is based upon you needing to make a concious decision in emergency braking conditions (not everday use, they are fine for that), which pedal or both pedals, which one harder... oh shit got it wrong....
And dont heap crap on me, its only my opinion...
My preference is a dual piston master cyl (one master cyl) and an inline biase valve. This gives you preset preferences (changeable) and only one pedal to select with the built in redundancy of dual braking systems.
Simple, safe.
-
The reason I say the dual piston single master cyl is in my Barracuda there isnt really enough room to use the dual master cyl balance bar system. This is a good system Ive used for many years in full sized off roaders.

im not going to be racing and i am trying to make it street legel

It is my understanding that as a general rule, brake bias is not street legal. It can be planed for in advance, and installed later, but might not pass the inspection for "street legal." Course this depends on your state's rules, etc...
Just something to think about.
-
If you are wishing to make it street legal then you NEED to see what the laws are in your state and make it that way. No other.
With this being an obvious home built type vehicle if its not built to the legal code and you get in an accident a lawyer will make it YOUR FAULT yesterday. Its gotta be by the code.
-
im in ohio so ya im not really that sure of the codes here

I agree
-
i tryed looking online but i dont know what the buggy would be concered
-
Michigan used to call them "assembled roadsters" but scince I have no desire for a street legal rail anymore I do not know if thats the same. Your state may be different.
-
You need to contact most likely the state patrol and document EVERYTHING you are told/by whom/when and exactly what the question was and what was the exact reply.
-
ya i might have to do that
-
OH, get answers in WRITING.
-
ya i am trying to find it online
-
Try picking up the phone. I can't even get definate answers on how to make my trailer pass inspection online. I even called the DOT and got nowhere. You're just going to have to pick up the phone and call people till you get the right one. Then meet in person and get everything in writing.
-
DITTO.Online will net you NOTHING of use.

what if i have 2 pedal boxes and 1 foot pedal with a proportioning valve on the rear??
