easy disc brake swap - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JJR · 01-07-2003, 02:40 PM

dream68 can you elaborate on the 88 truck you got the parts off of. Was it a 1/2 ton or 6 lug 3/4 ton? I have Hollanders on my laptop and would be able to post some info for folks. Hollanders does show the 67-70 vs 71-87 3/4 ton lower control arms being different. Which did you use? I have heard you could use the 88-91 3/4 ton 2wd 6-lug rotors on 71-up spindles using 71-up calipers. I went to Autozone and had them pull a 71 1/2 ton 5-lug rotor and a 88 3/4 ton six lug rotor and they were basically the same and appeared to use the same bearing.

dream68 · 01-07-2003, 03:24 PM

JJR: it was a 88 1/2 ton chev 2wd that all these parts came from. everything was ripped off the same truck, even the gearbox, but the gearbox will not fit...

JJR · 01-07-2003, 04:42 PM

Hollanders shows two spindles used on an 88 c1500 2wd. One for a 1" rotor and one for a 1 1/4" rotor. The spindle for the 1" rotor came on 88-91 c1500 and had a 1 1/4" inner bearing surface diameter. The spindle for the 1 1/4" rotor(which is probably what you have) came on the following:

This statement makes for some confusion: This arm (71-up) may have two different ball joints one being light duty, the other being heavy duty. I am assumming they would be different diameters.

I hope this info helps.

crazy longhorn · 01-08-2003, 01:48 AM

JJR,the info given to me on the 3/4 tons(from local napa) is the ball joints interchange from 71-86 or 87 on the pickups. I didnt see his book, so it was just info given to me. I do know from experience that the 71 3/4 ton lower ball joint will press into the 67-70 3/4 ton lower arms, but the steer stops are different on the older arms(same deal as the 1/2 tons, it will shorten the turning radius), & will require a little grinding on the stops on the spindles to straighten it up.......crazyL

JJR · 01-08-2003, 08:23 AM

That is good to know Crazy Longhorn. The local pull-a-part tends to have a good selection of 3/4 ton trucks and occationally an 88-up. The get $15 for control arms and spindles. I have also seen several sets of 88-up spindles on e-bay go dirt cheap. People put drop spindles on and basically give away the old ones. Since a already have a set of 71 1/2 ton control arms and spindles and new ball joints for them, I will probably end up buying a set of 6-lug rotors and use what I have.

dream68 · 01-08-2003, 04:22 PM

OK GUYS: the steering linkage is a tad sloppy in the spindle, so this is what you do. use the 68 intermediate shaft with the 88 tie rods. the inside tie rod end is changed to PART# : MOOG ES2020RL.(tie rod end). This setup fits and looks like a dream with no binding anywhere. the 88 tie rods are also bulkier than the 68 original setup..... I will be in touch with more updates as i go... KEEP ON TRUCKIN MAMA!!!!

dream68 · 01-08-2003, 05:04 PM

ALL PARTS NEEDED FOR BRAKE CONVERSION ON 68:::1968 1/2 ton top a-arm, 1970 3/4 ton bottom a-arm, 1988 1/2 ton ball joints(both), 1988 1/2 ton spindles, calipers, and rotors, 1968 1/2 ton intermediate shaft, 1988 1/2 ton tie rods, with the inner tie rod end changed to part#: MOOG ES2020. Brake lines can be changed if need be!!! GET TO WORK!!!

wnc mountain · 01-08-2003, 05:25 PM

This is great info...but...anyone know if this will work for a 70

dream68 · 01-08-2003, 05:49 PM

wnc mountain: i believe it should work because the boneyard told me the a-arms were the same from 68-70.

nac46 · 05-18-2003, 06:28 PM

New to the group and just saw your conversion. Tell me, i've got a streetable 72 donor truck. Can the front brakes be easily swapped in to a 68? Both are nonpower.

Mike Uerkvitz · 05-27-2003, 11:37 AM

I've followed this conversation with the understanding that this brake swap would apply for the 60-66. Can you offer your knowledge about this same swap applying to these year Chevys/GMCs?

Mike Uerkvitz · 05-28-2003, 11:37 AM

Will this conversion apply to the 60-66 model Chevys and GMCs. I have a '63 GMC 6 lug that desperately needs more stopping power.

jmcmahon · 11-17-2003, 01:43 PM

Has anyone else tried this conversion? It seems like a cheap way to add modern brakes to an old truck but I would like to hear from others that have tried it.

Tim Cline · 01-01-2004, 01:57 PM

Now where to find a set of 3/4 ton lower control arms cheap?

Blue Beard · 04-03-2004, 10:48 AM

Have you had it on the road yet...?

Was wondering if you felt any difference in the way it handled with the change..?

67ChevyC10Stepside · 01-30-2005, 12:04 AM

will the 73-87 stuff work? i've got a 86 frame im gonna be scrapping here in a couple weeks.

krue · 01-30-2005, 12:25 AM

You can just put the front crossmember off the 86 on your frame. A search on disc brakes should give you a lot of info on this subject.

67ChevyC10Stepside · 01-30-2005, 12:38 AM

i already have discs on my truck...was wondering if it was any use to anyone else.

FirstGen · 01-30-2005, 03:58 PM

the 73-87 stuff will not work for this style conversion unless you someone wanted to buy the aftermarket 6 lug rotors...

67ChevyC10Stepside · 01-30-2005, 05:05 PM

the 73-87 stuff has 5 lug.

FirstGen · 01-30-2005, 06:52 PM

Exactly. Not to mention it is a TOTALLY different swap. Parts used to do the swap are different.

FirstGen · 04-02-2005, 02:21 PM

yes, it looks like this... been running it for a while now so it doesn't look as nice but you get the idea. I used a 1990 chevy front end/parts that had 5 lug 1.25" thick rotors and went to AutoZone and bought new factory 6 lug 1.25" thick rotors and bolted them on.
Good luck.

Dano69c10 · 04-05-2005, 06:50 PM

This is probably going to make a lot of disc brake conversion vendors mad

.

Expect prices to go up on 3/4 ton lower a-arms and the 88 parts, or they will probably package your idea and still sell it for $700-$1000.

FirstGen · 04-05-2005, 09:03 PM

All in all, it's really not that cheap. I spent around $400 and I only bought what I had to plus two new rotors. You could easily spend $600 plus if you were buying all new bearings and rebuilding the calipers etc...

The only reason I did this swap was because I wanted to use all parts available at my local AutoZone, O-Riely's, etc. and not have to order special rotors from some company that could go out of business in 5 years.

shifty · 04-05-2005, 10:49 PM

Hey, FirstGen....

Can you provide any more detail about what exactly parts were necessary for your truck and what you got them off of? I've heard stories of people raiding 1994-1996 Impala/Caprice/Roadsters to get the 5-lug setup.

I am wondering if there is a need to get new a-arms (upper or lower), ball joints, tie rods or intermediate shaft with the method you chose?

I literally have the same truck as you (closer to stock though

) - I would probably do mine a bit different, just looking for some direction.

TIA

A search on disc brakes should give you a lot of info on this subject. __________________ "If it ain't broke, fix it 'til it is!" Being stupid ain't illegal.

I used a 1990 chevy front end/parts that had 5 lug 1.25" thick rotors and went to AutoZone and bought new factory 6 lug 1.25" thick rotors and bolted them on. Good luck.

Expect prices to go up on 3/4 ton lower a-arms and the 88 parts, or they will probably package your idea and still sell it for $700-$1000. __________________ '69 Fleet It ain't yours, if you didn't build it!

You could easily spend $600 plus if you were buying all new bearings and rebuilding the calipers etc... The only reason I did this swap was because I wanted to use all parts available at my local AutoZone, O-Riely's, etc. and not have to order special rotors from some company that could go out of business in 5 years. __________________ 1968 C10 build in process TT LSA/6L90e/9"

shifty Questionable Join Date: Mar 2005 Location: Atlanta Posts: 13,376	Hey, FirstGen.... Can you provide any more detail about what exactly parts were necessary for your truck and what you got them off of? I've heard stories of people raiding 1994-1996 Impala/Caprice/Roadsters to get the 5-lug setup. I am wondering if there is a need to get new a-arms (upper or lower), ball joints, tie rods or intermediate shaft with the method you chose? I literally have the same truck as you (closer to stock though ) - I would probably do mine a bit different, just looking for some direction. TIA __________________ If I've got anything up for grabs, it'll be here: 7-hole gauge cluster for a 67-72 p/u FREE (link) I can't check the forum daily.
