Which calipers for disc conversion

[POOR WHITE BOY]

Looks very good. Looks oem . I understand your parking brake in the other thread . E brake needs to be mechanical - please post and nice job

There is a Cadillac caliper that you can use that has a cable operated parking brake incorporated into the caliper, but they're very expensive. I was planning on putting a rotor on the drive shaft and using a small motorcycle caliper for the parking brake. It won't do much to stop me in an emergency, but it will let me pass inspection. With the gearing in the CUCV, it's easy enough to slow down by downshifting. Plus, you can just run into something and stop pretty easily.

Sorry that was a cheapshot.
My mechanical E Brake will either be a cable operated pinion brake or a brake mounted on the NP205 that is in my M1028 CUCV I have a Mico hydraulic parking brake setup until I find or build the E Brake that I have confidence in or build one myself.

GM used the same Dana60 slider caliper in the rear from about 99-07 range according to some GM parts bulletins I have seen and from talking to various parts counter men.

I have a CNC Mill and Lathe so I am only limited by my imagination.

You spoke about the studs not being pressed fit into the rotors, while this is true everything that is like this from what I have seen are mostly a slip fit from the front and are installed over the studs not the studs being passed through the rotors and then pressed into the hubs.

This IMO is a horse of a different color and or is not the same as how the rotors are a slip onto the studs on the front side of the rotor.

This setup makes the brake system a lot easier to service than the rotors behind the hubs.

Are you running a proportioning valve with that setup. seems with that set up it would lock them up real easy.

Wow, quite the pissing match this turned into! Good info all around, I do appreciate it all. A yes a proportioning valve, what type are you guys running? I am thinking about this one from Summit http://www.summitracing.com/parts/SUM-G3905/

Ive been looking for a good prop valve, Have not found one that neets my requirements just yet.

I just saw the one JWNathan posted a link to and will be having a look at that.

I wanted to mount the prop valve in the transmission hump or behind the seat on the left side but that would require running alot of extra brake line so on the dash looks to be the location.

I still want to mount it on the valve stem and not with bolts at 90 degrees to the stem as shown in this pic.

This is more like what I had in mind.

I tried that one and it was complete junk. It would not let it bleed all the air out. I tried everything then the stupid plastic nob broke so I said screw it and rean with out it. In my application it worked mint, but that was on my k10 with out hydroboost, and k10 callipers on the back. It makes your truck respond 1000x better.

I mounted mine under the truck where the load lever would be.

 

[JWNathan]

Really dstang97? A couple friends use them on their roundy pounders with good luck. I know with my ElCamino I hung the valve right up at the master, made bleeding much quicker. Tho that was a Willwood piece. May just try one anyway, Summit never gives you much hassle to return stuff.

Heres the valve I used before http://www.summitracing.com/parts/WIL-260-8419/

Some conversions need a adjustable proportioning valve and some don't.

I ran a Wilwood one on my rockcrawler. My 87 K10 didn't require one.

I was looking at the Ruff Stuff brackets, mainly because they are a local company.
14 Bolt Disc Brake Caliper Mounting Bracket (Standard SRW) [6090031] - $50.00

I should be able to get everything for the swap for around $270. Looks like it wont take to long to do either, looks very straight forward. I think I even still have enough DOT5 for the swp and brake flush. Thanks guys.
-Jesse

I already have all other parts for the conversion except for the short flexible brake line so I ordered the brackets....has anyone here used these brackets? What do you think? The truck they are going on started as a half ton, i am told that no change to the proportioning valve is necassary...is that right?
Thanks

 

[puppy]

I have a set of Ruff Stuff brackets on the shelf that I haven't gotten around to using yet. I like the one piece style of these brackets.

 

[ODdave]

if you wanna spend $$$ then just put a newer style 14bolt housing w/factory disk brakes....... thats what i have and you can buy any replacement part off the shelf for them. prolly get a whole axle for $500 and you will have the bigger pinion bearing and the stronger housing............ just my

OH YEA, and a factory cable opp. parking brake

 

[4bogginchevys]

What year does the 14 "FF" have disc? ...i'm not interested in a semi-float axle

btw: shipping was only 6.00, 2-3 day mail, I cant wait....

my 2003 2500hd has disc and is a 14FF

 

[davo727]

As far as the eldorado emergency brake style caliper , I will guess that with the truck actually moving if you try the emer brake and step on it as hard as you can you wont actually notice any braking force. It just looks good on there.

 

[doodaa]

can you use older gears in newer housing?I have 1985 14 bolt ff with detroit locker.I'd like to put dual wheels on ultimately

 

[notsosanestan]

isnt there a cadillac caliper you can use to still have the parking brake?

Trucks that new dont show up here at the local yard, next door to where I go there is a Yard called spaldings, they sell used parts off of newer trucks but the cost us unreal. 6000.00 for a 5.3, 12000.00 for a viper motor, 750.00 for that disc FF you mentioned....better off to stay next door and spend 2.00 to get in, and 115.00 for ANY engine, complete rear axle 65.00, driveline 10.00 etc. The newest vehicle there is about 2000, but only little cars...kia's and crap. Thanks for the info on that axle, I didn't know they still made the FF for the trucks.

 

[4bogginchevys]

Well, got the ruff stuff brakets on the truck today.....

Unfortunately they had to be modified for the caliper, the plasma cutter must have been off or something. The correct calipers just wouldn't quite slip on to the brackets. Grinder fixed that..... I see a couple others have mentioned the same brackets, any problems??

The truck stops well, very well. Instead of risking air bubbles trapped in the caliper we blead them in the up right position before bolting to the bracket, worked very well. A few taps from a wooden hammer handle and the remaining air came right to the bleeder for the final bleed on each side. If interested I can post more pics.

 

[kennyw]

I have the ruffstuff brackets and did not have any problems with them. My bleeder is also on the top... It looks like you put the calipers on the wrong sides?
