Yes, I do believe all of the aftermarket 6 lug front rotors are for the HD spindles.

Re: Disc Brake Upgrade Reference Thread
 

Hey guys, Im in the final stages of doing power disc/PS on a 64 c10.

I have two questions:

For the inner tie rods, Ive read to use the moog es2020 TRE's. However, when looking them up, there seems to be several different part numbers: 2020rl, 2020rlt, etc. What ones do I need?

For the brake system, I'm converting it to a dual pot master. I have all the line, the proportioning valve i need, but the master has the shallow hole for the intermediate rod, not the deep hole like the original single pot did. what intermediate rod do I need to use?

Re: Disc Brake Upgrade Reference Thread
 

I have never messed around with trying to mix and match the different steering components. I just convert to the entire '73-'87 steering linkage. All you have to do is drill 2 holes for the newer style idler arm. Then all your steering and brakes are of the same vintage. Much easier to remember what you need when it comes time to replace a part.

As for the master cylinder, if you have front disc brakes you need a manual brake master cylinder for a '71 and up truck. If you still have all drums, then you need a '67-'70 truck master cylinder. This is assuming you are running manual brakes, as this is what it sounds like.

Re: Disc Brake Upgrade Reference Thread
 

I am looking for some direction on how to find the correct disk/drum manual brake master cylinder for my '63 C10. I plan to keep my stock crossmember and use McGauphy's stock height spindles and front disk brake kit or similar components. Everywhere I look I see power brake masters for front disks but I would prefer the cleaner look under-hood of a manual master cylinder with the appropriate proportioning valve, if needed.

There is a wealth of excellent brake-related information on this forum but I haven't been able find this answer.

Thanks!...ned.

Re: Disc Brake Upgrade Reference Thread
 

I read all 15 pages of of this post and almost all of my questions were covered, but I do have to ask one question.

Besides being able to roll a complete front suspension under my 64 that is complete with disc brakes and the steering components, what is the greatest advantage of doing the swap to a 73-87 system? I would like to keep as much of my 64 original as possible, but if the steering, upper and lower control arms are that much better on a 73-87 swap, then maybe it would be worth the swap.

My original plan was to buy a set of 2.5 drop spindles, add power disc brakes and power steering; all parts that are easily found........but I'm still debating if the swap is the way to go or just piece meal the front end together and keep my original cross member and upper and lower control arms?

Thanks!

Dan

Re: Disc Brake Upgrade Reference Thread
 

I have to ask. If you are just wanting stock height spindles, why not just source a stock set of spindles from a '73-'87 pickup or Suburban? Then you can just get new rotors and calipers from your favorite locak auto parts store.

As for a manual master cylinder, you just need one for a '71 and up C10. As for the prop valve, you could also get that from the donor for the spindles.

Re: Disc Brake Upgrade Reference Thread
 

I prefer the '73-'87 control arms for the better (IMO) rubber bushings. I also prefer to use the entire '73-'87 steering linkage along with the idler arm, pitman arm and steering box. That way all the steering parts are of the same vintage, which is less confusion later on when replacement parts are needed. And no expensive aluminum adapter sleeves are needed. I also recommend upgrading to the larger '73-'87 lower control arm U-bolts.

Re: Disc Brake Upgrade Reference Thread
 

My goal is to drop the front 4 1/2 inches with drop spindles and coils. Even if I find a complete a 73-87 front end, I will need to replace the springs and spindles with the drop style.

You make a good point on keeping all of the parts the same vintage for the steering. I'll see if my local junk yard has any 73-87 trucks laying around that I can rob the parts from. If I get the front suspension parts, I might as well grab the power steering box, pump and all of the mounting brackets and hoses.

Thanks again!

Dan

Re: Disc Brake Upgrade Reference Thread
 

I got mine from Tim Tygerts obsolete chevy parts....mc for disk/drum non power was around $75 w/prop valve

Re: Disc Brake Upgrade Reference Thread
 

Thanks for the source! Tygarts has a lot of interesting parts. I just checked and the MC looks like it is $146 now :eek:

Until I sort out which direction I am going (changes frequently), I going to install a Cardone reman drum/drum dual-circuit master and live with my drums for a while. Captainfab has good points and a ton more experience with this so I may take his advice and start looking for a donor truck or 'burban next spring. If I can make space, Stripping a rusted or wrecked early '80s C10 with a 350 would create a lot of opportunities to fix my perfectly good, not-broken '63 C10 by adding old, used-up parts of unknown history. I've been down that road before so I know it's going to be a blast! :bann:

Thanks all...ned.

Re: Disc Brake Upgrade Reference Thread
 

Someone is selling a crossmember 71 with discs. I hear it bolts right up to my 69. I have a brake booster from a parts 69 to go on. Will I need anything else?

Re: Disc Brake Upgrade Reference Thread
 

I don't have any experience with the '71-'72 crossmembers, but it should beither a 100% bolt up, or no more that drilling one hole on each side and elongating one hole on each side. For that matter you do not have to change the crossmember. The crossmember and control arms are the same from '63-'72. You can simply just change the ball joints and add the disc brake spindles, rotors, calipers, etc.

You will also need a disc/drum master cylinder, proportioning valve, and you may need to change the intermediate pushrod in the booster. I believe the '69 booster would have the long one, and the master more than likely will be designed for the short one. You will have to check that.

Re: Disc Brake Upgrade Reference Thread
 

Change the ball joints from what to what?

Re: Disc Brake Upgrade Reference Thread
 

Remove the '69 balljoints and install a set of '71-'72 balljoints..........of course this is assuming you are talking about C10's

Re: Disc Brake Upgrade Reference Thread
 

Yes a 69. Thanks for the information!

Re: Disc Brake Upgrade Reference Thread
 

Captain
would those spindles work on 64-66 crossmembers?

Re: Disc Brake Upgrade Reference Thread
 

If you're referring to the '88-'98 2wd spindles, you will have to change the lower control arm to one from a C20. The '67-'72 C20 LCA's would be the easiest to make work. The '73-'87 C20 LCA's will work as well, but the bump stop bracket is taller. The LCA change is necessary to accomodate the larger '88-'98 lower balljoint.

Re: Disc Brake Upgrade Reference Thread
 

thank you

Re: Disc Brake Upgrade Reference Thread
 

Before you get too carried away, take a look in this thread:

http://www.67-72chevytrucks.com/vboa...d.php?t=604836

Need to figure out what happened with this member's installation.

Re: Disc Brake Upgrade Reference Thread
 

Hey fellers, I've been trolling this disc brake conversion thread for a while as well as researching other drum to disc info. I've got one important question for me, and that is that I'd like to use either.....my original wheels-love my bow tie hubcaps, or barring being able to use them, does some vintage wheel maker make a wheel that uses 66 wheel hubcaps while still having the offset for most 6 lug aftermarket disc conversions?

Re: Disc Brake Upgrade Reference Thread
 

I am not 100% sure about this, but I do not believe that the stock original '66 wheels will clear the disc brake calipers and rotors.

BUT, there are a few places that make OEM style wheels that will clear the brakes and still use your stock caps.

Here is one source for the wheels:
http://www.thewheelsmith.net/CustomW...cessories.html

Take a look at this thread;
http://67-72chevytrucks.com/vboard/s...d.php?t=556602

Dino did convert to 5-lug on this truck, but used aftermarket wheels to keep the stock caps.


BTW, I have family down in the area of Texas. We have a family farm just a few miles east of Fredericksburg.

Re: Disc Brake Upgrade Reference Thread
 

Hey! Thanks for the vintage wheel link! Looks like I can pick up some black 15" OEM's there when I figure out which way I'm going on the disc conversion...
Yup, Hill Country is mighty nice, albeit not too great this time of year with the cedar pollen!

Re: Disc Brake Upgrade Reference Thread
 

Apologies for pulling a quote from a few years back but this caught my eye.

As I have a 66 3/4 ton, could I just grab some new ball joints and spindles for an 88+ 1/2 ton, and attach them to the a-arms I currently have. Then I could piece the rest of the stuff (calipers, rotors, etc) from new parts, since I planned on rebuilding stuff anyways.

Is this doable?

Re: Disc Brake Upgrade Reference Thread
 

I have not been able to confirm that this will work, but I think there is a high possibility it will. I just have not had the extra $$ to buy a '63-'66 C20 LBJ nor the time to tear apart my '66 C20 to check the size of the balljoints. I believe it was member Tincan1966 that said that the '88-'98 Balljoints will press into the '63-'66 LCA's. I just have not done it myself.

Re: Disc Brake Upgrade Reference Thread
 

did we ever confirm that the 88-98 6 lug spindles work? and do the tie rods need to be cut for normal ride stance? to get the front end alignment?

Re: Disc Brake Upgrade Reference Thread
 

You might want to look at this thread:
http://67-72chevytrucks.com/vboard/s...d.php?t=620262

This combo of 88-98 spindles resulted in too much positive camber that requires either moving out the mounting point of the lower a-arms,...
or narrowering the upper a-arms.
I don't think this member (or myself) finds much money savings in doing this swap.

Quote:
ok, I said i would report back when i knew if my fix worked, and it did.
However, I'm just simply going to say that if your considering using 88-98 spindles to do a disc brake swap, don't.
I safely made mine work only because I am so deeply invested in it with new a arms, ball joints, rotors, calipers, tie rod ends, and a ton of time that I felt compelled to make it work.

Re: Disc Brake Upgrade Reference Thread
 

I want disc brakes all the way around on my 70', which is "better"/ easier, 6 lug or 5 lug? I currently have 6 lug.

Re: Disc Brake Upgrade Reference Thread
 

The 6 lug discs are not any more difficult than 5 lug. The tried and true way for 6 lug is to purchase the aftermarket 6 lug rotors for the disc brake spindles. Which is better is up to you as far as what wheels you want to run.

Re: Disc Brake Upgrade Reference Thread
 

Thanks Captainfab, what about the rear? What stock caliper brackets, rotors, calipers, etc fit the 12 bolt rear end on the 70' ?

Re: Disc Brake Upgrade Reference Thread
 

There are not any OEM caliper brackets that will boltup to the 12 bolt. I make 5 different rear disc brake conversion brackets.

Re: Disc Brake Upgrade Reference Thread
 

OK, Iam confused, Why not just swap the cab , bed and nose over to a 87 donor truck or earlier model with all the front end and power steering and power brakes and disc brakes. I am a newbie at this but to me it seems easier and faster to just swap them over. Or maybe it is not that easy to do. Thanks Doc

Re: Disc Brake Upgrade Reference Thread
 

No it is not easier to install a '60-'66 cab onto a '73-'87 frame BTDT. It is one heck of a lot of work and due to the differences on the '73-'87 frame you end up with a 3" body lift. Then you have the possible legal problems with the frame and cab VIN's not matching.

A power disc brake and power steering upgrade can easily be done in a weekend.

Re: Disc Brake Upgrade Reference Thread
 

Thanks again, Captainfab! Do you sell your caliper brackets for the 12 bolt rears?

Re: Disc Brake Upgrade Reference Thread
 

Thanks for the info Capt. Doc.

Re: Disc Brake Upgrade Reference Thread
 

All of the rear disc brake brackets that I make are for the '64-'82 truck 12 bolts and the '80-'87 10 bolts. There are links to the for sale threads in my signature line \/ \/ \/

Re: Disc Brake Upgrade Reference Thread
 

1994 donor 2500 van will the a arms& spindles work on 65 1/2ton

Re: Disc Brake Upgrade Reference Thread
 

The a-arms are totally different and will not work. The spindles were previously thought to work, but a few members have had trouble with getting the correct camber degree. So until a solution is found, I would advise against using those spindles......unless you want to work out the issue.

Re: Disc Brake Upgrade Reference Thread
 

Nevermind.... This thread has changed since the last time I was on here my question was answered already.

James

Re: Disc Brake Upgrade Reference Thread
 

Well, I take that back. That did not exactly answer my question. What is the purpose of swapping the C20 LCAs onto my 64 for the 88-98 spindle swap? My spindles bolted right up yesterday, but I must be missing something somewhere?

James
