Re: 14 bolt rear discs
Did it 14 years ago..... I don't tow enough or wheel enough to really notice a difference. On top of it, I needed to do something about a parking brake (the Caddy calipers didn't work to hold my truck). In hind sight, probably not worth the effort, but it gave me bragging rights.

Re: 14 bolt rear discs
Like nonstop said, it's not really worth it unless you want bragging rights. My Caddys with rear discs work nice but forget about keeping the parking brake operational. Maybe another system would have possibilities but don't use those Caddy rear calipers.

Re: 14 bolt rear discs
Doesn't the late model stuff with factory discs work on older 14 bolts?

Re: 14 bolt rear discs
I thought so too.

Re: 14 bolt rear discs
If it does (I haven't tried it) that would solve the parking brake issue right?
Do discs (on the rear) really offer that much difference in braking performance? I've had several late 14 bolt trucks with drums and discs and really didn't notice any difference in braking. Holding ability of the parking brake with the drums was much better than the discs.

Re: 14 bolt rear discs
It's not a bolt on. You either need to weld the late model ends on, or make or buy an adapter. I think the place that made the adapters has since stopped. I forget the name of the place, but was in Gilroy or Hollister, and in excess of $200 if I'm not mistaken.

Re: 14 bolt rear discs
I think it was Right Gear or something like that. Can't find the adapters on their website anymore.

Re: 14 bolt rear discs
I have been looking at this kit.

The one bummer is, the disc rotor's go BEHIND the hub, or in my SF case, axle flange. So I have to pull an axle to change my rotor's, but it'll probably be five years before I wear them out anyway.

When I priced it out, newer stuff, rotors, backing plates, everything, came to 327 because of core charges. That plus the cost or difficulty of the spacer is what made me choose the Lugnut4x4.com kit.

Re: 14 bolt rear discs
I'm curious to see what you think of the disc performance compared to your drums.
What size rotors are those?

The rotor's are stock K20 squarebody size, according to Billavista they are 12.5" diameter, 1.3" thick. They barely clear my 16" wheels. Also, I used the larger JB7 calipers, 3 5/32" piston vs the standard 2 15/16", I was betting on my larger 3/4 MC being able to handle it, if it doesn't, I'll add hydroboost ![]()

Re: 14 bolt rear discs
I thought this conversion required larger wheels Like 19.5?
Do not remember any disc conversions that would clear 16" wheels. I would consider the conversion on mine if the parking brake problem could be resolved. Desert |

Re: 14 bolt rear discs
Converted from drum to discs, but went back to drums.

Re: 14 bolt rear discs
Because the braking performance wasn't there? Parking brake issues?

That isn't blanket criticism of rear discs, it's an individual opinion and I recommend doing what you like based on experience, usage, and goals. I know the mudders prefer disc to prevent clogging, off-roaders for weight savings, and it has a purpose. We all have different needs and I don't judge others. For me in this case I got glassy eyed and swapped when I didn't really need to. When I switched back to drums I went with 13 x 3 drums off a 3500 series Crew. That's a lot of brake, more than enough for me. In the end if your happy with the set-up that is what counts.

Agreed. I've had a few trucks with those and they worked great for me as well. Discs are sure easier to change the pads though ![]()

Re: 14 bolt rear discs
No doubt there, I'd be a happy clam if the 14BFF brake drums just slid right off like a pair of socks.

Re: 14 bolt rear discs
if you're gonna do it, just get an 02 disc rear and be done. rotors slide off, ebrake works. they make brackets to bolt all that on an older 14bolt, but they're expensive and its easier to just move the springpads and move on.

Re: 14 bolt rear discs
Check out the Wildwood parking brakes available at Summit (everywhere else I am sure too).
Anyone try one of these? https://www.summitracing.com/search/...ibanner=SREPD5 |
