I was looking at some of the floor mount pedal set up. They have two brake master cyclinder behind the pedal. With that set up, the car will have no power assist brake, am I correct?? Is that a possible way to keep power assist when going floor mount.

- What are the advantage of going non-power assist??
- What are the advantage of going twin master cyclinder compare to one??

I am planning to do the floor mount pedal conversion so does anyone has any feed back??? are they more comfortable compare to firwall mount??

Depends on the setup, but most that I have seen do not use the booster. Got a link to the product you're looking at?

Is that a possible way to keep power assist when going floor mount

Yes, but fabrication will be involved. I haven't seen a floormount kit that offers a vacuum booster.

- What are the advantage of going non-power assist?

Simplicity, weight, reliability, cost, adjustability. There's a pivot bar on the floormount that can multiply your pedal effort to give you assist.

- What are the advantage of going twin master cyclinder compare to one??

Each cylinder can work one pair of calipers. You can finetune the braking bias, as well as having reliability in case one circuit fails.

does anyone has any feed back??? are they more comfortable compare to firwall mount??

Why do you want a floormount?

The only reason I am contemplating a floormount is to adjust the position of the pedal box. I see no real benefit to the floormount otherwise. There's always the rollbar mount.

im short as hell - so i was contemplating floor mounts when i first for my wheel and seats - bc with the qr and hub the wheel gets closer and the pedals are still the same place.

I hear you. I'm in the same boat. My arms are much longer relative to my legs. I'm built like a neanderthal :-)

So if I'm comfortable with the pedals, the steering wheel is in my chest. If I'm good with the wheel, I can't reach the pedals.

It may be easier to fabricate just the pedals than to get the whole floormount.

Yeah you should see what you can do just bending stock pedals and adjusting the pedal stops.

might give you the few inches you need.

I am thinking going floor mount since I feel its is easier for me to do heel-toe with the pivot point on the bottom. Also after I removed the carpet, the pedals are higher off the ground and I am pretty, 5,8 with size 9 shoes, so it is not very comfortable.

I am looking to get this:
Wilwood Engineering - Brake Pedal Assemblies (http://www.wilwood.com/Products/005-PedalAssemblies/001-FMP/fmbp/index.asp)

I was looking through tilton and AP, but find out willwood is the cheapest.

yeah, im having the same problem im about 5'9 something like that with short legs... and with the QR when my feet reach the pedals the wheel is almost on my chest... not comfortable at all...


would a floord mount pedal setup be ok for daily driving? since they don't have booster and all that? and besides that spending that much $$$ (im looking at tilton's) i would rather take of my QR and be happy...

couldn't you just run a telescoping steering wheel hub to help find that 'sweet spot'... wait idk if they even make those aftermarket do they? i think i've only seen them oem on cars.

easy solution, remove quick release, doesnt really deter theifs, or replace w/ slim hub and slum QR, problem solved,

might look ghetto there, but you could solve your problem a hell of a lot easier, if the brake is hard to get to also, do the same thing

BAM!!

good suggestions but I don't want to cut any corner for my car. Especially on brakes, I am going to do it the proper way. Thanks for the suggestions.

quick release arent for theifs... the point of them is to make it easy to get into/out of your seat(bucket) and also it makes it easier to work in the car sometimes... and slim QR are a bitch to take of sometimes compared to the regular size QR...

Yes. I also have slim QR but it's not enough. Even the stock wheel isn't comfortable.

any OTHER pedal box or floor mounted pedal inventions you could sharE? the last thread about this ended up in nothing... somebody said something about modifying the stock ones... how? maybe that would give me enough play so i could move them closer to me and not have to hit the pedals with my toes or have my wheel where i can rest my head if i just look down...

The most concern for me is going non-power assist. how daily it is and what is the feed back like?? Because when I turn the car off and step on the brake, the feed back is really weird. Is it how non-assist brake feels like???

Turn motor off, release ebrake and let it roll, then try and brake. That's how its like. But the like some have said you can cgange the pivot point to get better leverage. I hope you know how to bend up brake lines and buying correct fittings for the lines.

I don't know why making adapters for your stock pedals for you to reach would be cutting corners? Your cars not a race car and your just gonna run into more problems then you can handle.

Get some of those drill in pedals stack some washers behind it to space it out. Done!

yeah, stack 1,000 washers and make your pedals bulge like half a foot from the stock ones... great work...

Uhmm yea smart ass, yea thanks for contributing. That was an idea to snowball into something better. If you wanna be all awsome you can go out and someone cnc ur siet for you!

The way I see it, ur gonna have this expensive race pedal setup with half assed brake lines, throttle cable and clutch lines. Check out how pedals are setup up for midgets damn pedals are all spaced out and they get around fine

My mine is pretty much set on getting the floor mount pedal. I don't cut corner when I build my cars with cheap/half ass fittings and line. Everything will be done professionally. I think I can give up the power assist and live with it

No power assist, your gonna just have to pay more attention on the road and plan to give yourself lots of room to brake.

And im hoping when you say professionally done you mean taking it to a professional shop. if your doing it yourself and want to be professional about it, buy plenty of line, and good double flare tool. ahh whatever im wasting my time. hope everyone gives you plenty of browny points for this setup. take plenty of pics

no, there is a difference between running true manual brakes and running your car on a vacuum boosted brake set up w/o the vacuum of course it brakes like shit.

A true manual setup will be super fucking touchy, especially if you're running a bbk kit.

There are kits for this type of set up or you can do this to eliminate the brake booster. A solid CNC plate.

I mean it's a bit more complicated than just removing the booster and bam manual brakes, you will need a prop valve that will let you adjust bias... It's more ideal for track threshold braking and pedal feel.

Power brakes are more of a convenience and safety feature ex. (ABS)

Its good to here that they are touchy and sensitive over the weird feeling without a brake booster when the car is off. My car does not come with ABS so that make things simpler. My car will be mostly weekend driving and planning to hit some of the tracks during this summer!!
