My whole braking system - thinking out loud

[Captainfab]

I'll put your name on a set, and get them over to the powder coaters tomorrow. I'll send you a PM to work out payment details.

As for the proportioning valve, some guys are using the stock disc/drum one with success, others use the disc/drum with an adjustable in the rear line, and others run only an adjustable in the rear line. There is also the disc/disc proportioning valves. I would say it will somewhat depend on which calipers you use. If you're going with the Wilwood dual D52's, they recommend using the 1.5" dia piston models in the rear with the 2"up front to help maintain some of the braking bias. So I guess decide which calipers you are going to use and then we can go from there.

Do you have an application for those rotors? It sounds like you setup and drilled the holes on a CNC? How long do you figure it took you to turn the original rotors into hubs? It seems like someone already makes aluminum hubs that will work on the truck spindles. I'll have to find them and see how much they are.

I must have been in a hurry and didnt double check the spacing in the autocad file becuase I drilled the frist patten to 5.25.. lol... these rotors are at minimum anyway, but the second pattern (shoulda been the 1st) was spot on.



and with the rotor turned upside down, you can see how it fits perfectly onto the stock replacment rotor and already has a bevel. For those who will notice the studs dont stick out much.. the stock rotor was not turned into a hub yet so the Dodge rotor was sitting down on the stock rotor surface.. I think the studs will need to be longer anyway



Weather permitting, I will be going to the pick and pull for a spindle nut and washer... Ace hardware didnt have a 3/4x20 nut, or castle nut... plus they want 5 bucks anyway.. then I will be able to snug everything down and start working on the caliper adapter bracket

KORE3 makes billet alum hubs for C10's. They're very nice & were less than 4-bills.

[Captainfab]

That's right, that was one of them. Thanks Scot. Chris Alston makes them too, but I don't know if they're available seperately. Are the KORE3 hubs available in a 5x5? The website just says the have a dual 5 x 4 3/4" pattern.

No CNC here, just a lexmark printer, punch and hammer... I didnt turn the rotor into a hub just yet... I wanted to measure the runout of the hub, or see if there was any before I cut up a brand new rotor.
As far as the rotor its from a 2003 newer dodge ram 1500. As far as the new pattern I used a template I created in Autocad. Before I attached it to the face of the rotor, I got a pick and poked a small hole where the chevy pattern was (makes center punching it supa easy. I attached the pattern to the face of the rotor with some stuff called butyle aka dumb dumb (it's like sticky tack but for cars) and stuck it onto the face of the rotor. Turned it upside down and moved the pattern untill everything lined up. Silmply took a center pinch and hammer to mark the new pattern. Removed template and center punched the new holes a second time. Used a 1/8 bit to start with, then progressed to 17/32. Later I chosed 17/32 becuase it was a hair larger than 1/2 to give me a little wiggle room incase a hole was not 100% on the money. I will put a picture of the pattern I am refering to.

edit:
heres the screenshot of the pattern I whipped up... the ones with the (X) is the dodge, and the other... obvious.

They are available in dual patterns. Mine are 5x4.75 & 5x5.

True on the above

I have been talking back and forth with Tobin at KORE3 the last couple of days. I am getting ready to buy their kit with 14" front and 6 piston C6/Z06 setup and 13.4 4 piston on the rear. If you skip the parking brake it is actually a reasonably priced kit. I just need to make sure the calipers will clear my wheels.

How much are we talking about for rea$onably priced

looking at kore3's site, its around 1100 bucks
http://www.kore3.com/proddetail.php?prod=10336-03

nice stuff but just out of the budget... plus that might be way too much brake for a normal truck...

[jasonb72]

Granted I said reasonably priced..for what you get. I am looking at getting their complete kit as I described minus the calipers since I have a hookup for GM parts at cost. This will cost me 1500 plus whatever the calipers cost me, so I am hoping to be right at 2-2100 for the total cost.

I compare this against what I bought from ECE which was a 4 wheel disc brake kit all stock parts with CD&S rotors for $1500.

This means I get the bigger rotors and much much better calipers for around 600 more than the other kit cost me.

That is reasonable to me.

Got my Captainfab D52 rear caliper brackets today.
Excellent quality product!

Thanks again for designing and manufacturing these brackets.

[Captainfab]

Thanks for the compliment Keith

I finally got a for sale thread started for these rear disc brake brackets HERE

[skeeterbug]

looking forward to getting my captain fab d52 caliper brakets, my willwood calipers and disc/disc prop. valve came in sat via fed ex truck. i also went yesterday and got the rotors and a dual diapram booster to go on one of cap. fabs booster brackets. everything is painted and disassembled ready for an upgrade, i cant wait to see the difference manual brakes to four wheel power disc brakes make. lolife 99 did you get your lines yet, just wondering if anyone has figured that part of the process out yet? also what brake pads to use, hmmmm.....?

I plan on using braided lines.
Any line that accepts a 7/16-20 banjo bolt will work.
Speedway Motors sells them in rubber ($39/pair) or steel braided ($49/pair) for a reasonable price.
Make sure you get D.O.T. approved brake lines.
Any stock D52 pad will work. (Same as the front disc brake pads)

Really? Makes you wonder why any one buy rubber if stainless is only $10.00 more. I guess thats for the retro builds.

[crakarjax]

Don't the rear brakes use hard lines?

Rubber:
Part# 617-8563 $39.99/set
(Includes banjo bolts, clips, and brackets)

Steel braided:
Part# 617-8562 (front 16" hoses) $49.99/set

Part# 617-8564 (rear 8" hoses) $49.99/set

[lolife99]

Rear disc brake calipers require a flex line.
Ususally a steel line is mounted to the rearend housing and then converted to a flex line at each rear wheel.

[N2TRUX]

Thanks for sharing the part #s Keith.

Normally yes. In this application they are using front calipers on the rear so it requires the same soft line.

[smashingchuck]

I might add that I found out the hard way that the front flex lines for a 67-72 are much shorter than those for a 73-87.

[suttoncurt]

Wow - I just realized i screwed up! I ordered four of the same front caliper . For the back I need the one with the smaller piston ? I ordered from jeff and he said something about it but i thought he was talking about rotor width ? Can someone chime in on this - Thanks

Yes, you want the smaller bore for the rear.

Thanks Chuck - Ill get in touch with cpp jeff and get it corrected!

[Captainfab]

Your parts shipped out today. If you didn't get an email with tracking info, let me know. Thanks.

[skeeterbug]

i got my smaller piston calipers (willwood) from jegs, i belive they measured 1.25 or 1.5, i know the front calipers measured 2.0. i will have to double check the rear calipers measurement to be certain
