6 lug rear disc install done!

[Musclerodz]

Got the new brackets fabricated and welded on today. It was fairly easy to do. I will have to re-powdercoat the rear end but only after all the brake line and e-brake has been mocked up. Brakes are off '03 burb. I would have shown the calipers installed, but they sent me the wrong ones, correct ones should be here in a few days.

nice

2wd or a 4x4 blazer?
Must be a 4x4 with the 6 lug disks but maybe not.

What the overall plans for your blazer?
Lift/drive train/gearing/tires...ect. Sorry if I missed that somewhere...

Great start with the brakes.

Nice project, I'm interested in the final write up as well

All 1/2 ton 1999-2006 'New body style' FS pickups are 6 luggers. GM had 4 wheel discs until 2004 or so. Then they want back to the front disc / rear drum setup.

Right now I am still trying to work out the brake line that attaches to the rear and e-brake set up. The rear discs are off the shelf 2003 Suburban or equivelant Hollander interchange. The actual brackets are fabricated and can post dimensions. I am working with classic tube to get me the correct setup. As soon as the parts arrive and work, I will post a full article.

Ok I'm kind of a brake Newbee. Should you upgrade the front discs to keep up with the very efficient technology of the new rears?

Also, are these ABS. I can lock up my front discs on my 72' with no sweat.

[dennislbrooks]

cool - did you use the whole 3rd member from the 03 burb?

[Musclerodz]

4wd. I cutoff the old mounting flanges, and made new ones. They went right back in the same location, just clocked differently. Not sure they would fit under stock wheels yet. It has a 13" rotor. I am running 17x9 wheels, so no problem for me there. The best part about this swap is the part cost me $200 including shipping and it is all new GM stuff.

Sweeeeeeeeeeeeeeeeeet

Hey how'bout a parts list and a write up for the FAQ's if it's not too much of a hassle?

As soon as I get the e-brake cables figured out, be happy to do it.

Thanks Mike!

Finally got the rear calipers in. Man, these are huge. It will require a 16" wheel minimum to run these brakes.

[krue]

Can't wait to see the FAQ.

[Musclerodz]

Got to mount the axle to the chassis before I can figure out which ebrake cables to use. Since I am going with a 4" lift, I may end up using extended cab or long bed cables for the extra length. that will take some guessing. Should be able to finiah that this month. Next time I stop by the dealer I will get a full list of part numbers.

Musclerodz, any update on the parts list?

[69TowRig]

You will not get ABS because the tone ring, sensors, computer, and ABS controller, speed sensors, etc, would all have to be swapped over. All he did was use the brake hardware itself.

Nice work, I wonder if there is a similar OEM setup that I can put behind my 15" wheels.

[ghetto_superman]

bringin it back... any parts list yet?

[Musclerodz]

Yes, these brakes will require 17" or larger which is what I had planned from the start. Burbs are stock rear disc even of the '06 and '07 models. Trying to make this stuff work I found a rear disc brake option code JL2 for pickups. Here are a few part numbers:

Disc brakes: don't know, got them off car-part brand new 2003 Suburban
$209.00 with shipping
e-brake cables: 15087072 $39.95
15087071 $29.95
brake hose with bracket (would have bought stainless braided hoses but need the bracket that holds the hose and only serviced with the hose for some reason) : 21999529 $39.73
21999528 $39.91
clip (holds the RH e-brake cable and hard brake line on top of the pumkin):
15206266 $ 3.64
guide (on '06 JL2 trucks, hold the e-brake cables freely so they can move with the suspension):
15258706 $ 8.43
15221823 $ 1.71

Total parts to date : $379.79

Still have to come up with a custom hardline and figure out how to make the e-brake cable work, but that will all come one I get the rear end built and installed which is what I am working on now. Unfortunately progress has been slow the last few months and I am hoping that will change over the winter.

SWEET SWEET deal man! IIRC you have dual piston calipers on the rear.. ive got a set of single pistons (disc conversion kit w/ lowered spindles from brothers trucks) for my front already... and the question is.. would it be dumb to have singles in the front and doubles in the rear? would the 'correct' thing be to have them match?

I am putting the '03 brakes up front as well so they will match when done. What I forgot to mention above is that I had to machine the center of the rotors out to clear the large bore. Luckily I have a good friend who is a machinist.

It would be best if they matched, but you could run an adjustable proportioning valve to tune the balance on the brakes which I will be doing. The larger brakes serve a saftey issue most people ignore when installing bling wheels (22" and larger) or 40" off road tires. All that extra rotating mass requires larger binders to stop as effectively as the stock stuff stopped original equipment. I will be running 18" wheels and 33" tall Nitto tires.

[ghetto_superman]

ok i gotcha. so now when you say you had to machine out the rotors, do you mean the area that appears to be the e brake 'drum'? or just the hole in the face of the rotor that the axle hub pops through?

[Musclerodz]

The center hole of the rotor that fits over the axle hub.
