Custom big brake kit?

[MyCreation68]

I've been tossing the idea of making a big brake kit for a couple vehicles I have(my 68 Dart and my 98 Ram) that for me will be cheaper then buying a pre made set that only comes with a one piston caliper or a two piston caliper(I've seen anywhere from 2-4 grand us for one pair of calipers, rotors and brackets) my plan the calipers cost 600 bucks us each and their 6 piston lightweight race calipers.

For the front:
For calipers I've chosen Willwood Superlite SL6R/14 calipers:

I'm going to go with a pair of 14" x1 1/4" disc rotors that bolt to a brake hat. They cost about 350 bucks a rotor.
I'm going to custom make brake hats out of 6160 Aluminum that I can buy from work.
And I'll mill caliper mounting brackets out of I'm hoping to use the same 6160 aluminum type of material

For the rear:
Same calipers and rotors.
Custom made Cast iron hats sized to house custom made ebrake components from a smaller import or domestic(think neon, integra andthing with a drum brake size in the rear of around 7" -rotor inside diameter is 8")
Custom made caliper/ebrake mount of 6160 Aluminum.

Reason I'm doing this is because I can make most of the components at work myself(CNC Machine shop)

I'm thinking of doing this big kit for my brakes first before doing a bunch of engine work just to keep the safety up.

In total I'm not looking at a huge amount of cash into this project more of time and effort of taking measurements and trial and error.

I plan on sharing the plans once I get the project successful so If anyone else is interested it'll take me a while(a year or so) to do this project but I think it'll be worth it. I know it's a little overboard on the braking power(6 piston calipers on 4 wheels  talk about  ) It's just the price i can get the 6 piston calipers for is about 50 bucks more then the same type of caliper with 4 pistons so it's one of those why not things.

Just wondering what you guys think about my plan and how possible it'll be. total price before shipping for calipers, rotors, and pads before shipping is 3746.38
which compaired to a SSBC kit(front disc brake version-$1000, optional perfomance aluminum 2 piston caliper-$1000, and another thousand for a single piston rear disc conversion kit. So theirs is only about 3K but I want more performance then 2 piston and single piston caliper but theres others like baer who offer kits for like 3-4K depending on application but only for the front.

Sorry just noticed wrong thread if a mod could mod this that'd be great. Again sorry. Clicked the wrong tab

How much are those 6 puck calipers?  I always thought that a guy could put two 4 piston Dynalite calipers on each front hub and have even more brakes for about $240 per side. I suppose that the master cylinder would be too small then.

My Volvo has a dual brakeing system that has four piston front brake calipers and two piston rear calipers. The dual master cylinder controls two pistons on BOTH front calipers and one complete rear caliper per circut with the other circuit running the other two pistons on both front calipers with the other side rear caliper.   This way, if one of the brake circuits fails, the car still has two pistons per front wheel working and one rear wheel.

The same type of system could be set up with one circuit running one Dynalite caliper and the other circuit running the second caliper.  6 Dynalite calipers total since the rear brakes do only about half the braking of what the front brakes do.

It looks like the Mopar spindles are set up for two calipers already. How about sliding aluminum singe piston race calipers?

[moparrr07]

really the only reason to run those expensive calipers on these cars is for weight savings, yes the stockers are 1 piston but its a huge piston, the more pistons you have, the smaller each one is, about the same size surface area- my napa stock b body calipers(slighter bigger than a body calipers) will lock up my 235 sticky road race tires the first time you touch the cold brakes after the tires have warmed up, those caliper only cost me $20 some a piece and i can stop in the same distance as a brand new corvette,

not to just trash your idea, but there is no need to spend over $1000 on the brakes all the way around when you will lock up the tires in a second

[Volvo Heretic]

Well, your probably right! Too bad Wilwood doesn't make aluminum calipers for Mopars? I wonder how hard it would be to adapt the small GM calipers, but then the piston would likely be a lot smaller?

[NYrr496]

Go to AR Engineering's website. They make a really great kit to mount Wilwood calipers on Mopars and it's WAY cheaper than what you're talking about doing. Their Viper kit is cool as hell.

[Scampin]

I bought the brakes for the Scamp from Bill.  He had (maybe still has?) a package deal with the tubular control arms, adj. strut rods, new spindles, stainless brake lines, etc. using Wilwoods 12.19" Drilled and Slotted rotors, 4-piston calipers, for around 1800 bux.  I also got the rear Wilwood brake kit that uses the 12.19" Drilled and Slotted rotors, 4-piston calipers, with the parking brake inside the rotor.  I have around 2500bux in brakes and most of the front suspension.  I don't think you can really need much more braking than that.

[kowski71400]

have you called willwood to see if they have a break kit that size for the mopars? when i called them for breaks ( altrekation ) , they had a 13" kit with the 6 piston calipers for ( i think ) under $2000.00. it may have been a little more. i can appreciate your idea, but you may be able to get away easier and cheaper.they also have 12" kits for the back, with e-break, for $600 to $700.

[MyCreation68]

Yeah I happened to be looking at Mancini Racings website and checked out the brakes ad they have a pretty nice kit for 600(if I remember correctly) bucks for the front from wilwood they also have the same for the rear so thats what I'll use. Anybody know if my stock brake booster will be good enough with the willwood 4 disc master cylinder?

[moparrr07]

you wont want a brake booster, when you put on bigger calipers it make the pedal easier to push, plus what your talking about will grab very easily, there is no need for a booster on an a body- my manual brake car has just as easy of a pedal to push as any brand new car out their, manual brakes give you so much of a better feel for whats going on in the front end-

what do you plan on running for tires in the front?

[MyCreation68]

I'm going with 225/40ZR18 on the front. their about 9inches wide by around 25 inches tall so theres quite a bit of area.

[Scampin]

This is what the the rear wilwood kit looks like with a 17in wheel.  I was hoping it would fill it a little better but I'm going to live with it.

[MyCreation68]

I think that looks good although I would personally want red calipers

[Scampin]

I agree.  I've been thinking about powdercoating them.  Just not sure how hard it would be to disassemble them to do so.

[moparrr07]

a 225 is only 8.8 inch at the section width so only about 7 inches on the tread-

once again, just a warning, you will lock those tires up in a second with 35 year old brakes and brand new road race tires

[gregpurcell]

I still like the Mopar Action plan to use the later model stock 11.75 brakes.

I put Porsche brakes on the front of this B body.

[andyf]

Here is a late model Viper caliper on a Baer 2 piece 13.5 inch rotor.  We used Fikse rims for this project.

Calipers like those six-piston Wilwoods are lighter because they're alloy and, being alloy, they dissipate heat better - your stock iron calipers won't do that. Also, the four- and six-piston calipers distribute braking force more venly over the pad making more effective and positive braking. Your single piston brakes lock up quickly where the six-piston caliper won't do that. It's a more progressive feel. You can also get better pads to go with the Wilwood calipers. If you road race with those stock mopar pads you'll be hating life.

i won't argue with you on the stock brakes, they do work great. But under extreme use the Wilwoods will outperform them every time.

[kowski71400]

andyf, those two set-ups look nice. do you make your own caliper mounts? i also thought about using porsche brembos on the front of my car.

[moparrr07]

i totally agree, but i have never really overheated my brakes with 10 or so quick stops from 80 or so in a row, and it will lock up my tires every time while still keeping lots of feel with them, i can keep my tires right on the verge of locking, just like having abs

obviously, willwood calipers are better, theres no doubt but there is absolutely no need on a 3500 lb car that wont be road racing and is using small tires

i have napa premium pads, its not like im running around on 35 year old pads, i don't feel that my front brakes could get any better than they are right now- $200 at the most for just the brakes

If you ran a set of 13 disks you would change your tune real fast  and probaly realize how unsafe 30 year old brakes are compared{to a modern setup }
the diff is night and day compared to stock..No matter what the weight~

[moparrr07]

tires can only grip so good, i can stop from 60 in 105 ft on marginal pavement on the 5th hard stop, only 2 feet more on the 10th- my brakes are not 30 years old, everything is new, a new vette will do it in 110ft, i dare you to spend $1500 on the front brakes and stop any faster with a 235/60r15

this is all with 195 general purpose tires on the back with crappy 9 inch drums on the back, when the new rear end gos in, ive got 11x2.5 finned nos brakes to go on, along with 295 tires, my goal is 95 feet on the average road, no doubt it will be much better on a prepped track

[Drdodge]

no..it's how much and how fast you can convert mechanical energy to thermal energy
Tires roll, Rotors and pads convert the surface area of the rotors,pads and also an increases area in dynamics to the tire size{to a point} boils down to surfce area~

Not to argue, but you are telling me that your car with stock disc single piston brakes up front and 9" drums in the rear with 235/60/15 tires in front and 195/??/?? tires in the rear stops quicker and better than a New C6 Corvette which is probably lighter, has 12.8" in front and 12.0" disc's in the rear with huge meats?  I just want to get this clear in my head.

[andyf]

Some input for the original post: Check the price on new Viper calipers at your local Dodge dealer before you buy those Wilwood calipers for $600.  The Viper calipers area available for about 1/2 that price and they are a better quality caliper than the Wilwood.  If you're going to build your own kit you should at least use the higher quality caliper when it is less expensive.  The new Viper caliper is one of the best deals going in the world of big brakes which is why I designed a kit around it.

Not to worry cam slant's cant make enough power to have braking issues PS
Check your pm's I need to know where you sent the axles and how you sent them~

[NYrr496]

Andy, Aren't the Viper calipers made by Brembo? And what rotor are you supplying with your kit? I want that for my roadrunner.

[BIG DOG]

Andy I looked at your kit thought it would be real nice went to the dealer here .$2000 for a set of calipers and there were none available. OUCH!!! where are you getting them for $300 ?? And I assume that is for 1
Do you have a part number that i could give the dealer ?

[moparrr07]

all i know is a can stop in 105 ft, and now that i look it up, a corvette is rated at 118ft on autos msn- only thing i could guess is whoever did the test is handicapped or the tires arnt that great front the factory, they are probably 80k mile lasting snow tires and if you put on some real ones i bet under 100 wouldn't be out of the question, plus my pads are superior to a stock gm piece so yes, with my stock style brakes, i stopped in 105 ft, do a test after you put on your $2000 aftermarket brakes and see if its any better,-

its all about the tire for stopping distance and see how my brakes have not over heated on me i dont know what else to tell you
