Has anybody installed aftermarket disc brakes to their Yukon?
I am looking for a good Complete package

You asked about brakes, the subject line says REAR BRAKE upgrade... 70% of the braking force is up front. I am going to be adding a larger than stock rotor package on my 03 Yukon. I think BREMBO makes a kit which includes larger diameter rotors and adapters to use the stock brake calipers. I think that would give the biggest advantage with the least amount of $$$ etc. Has anyone installed one of these BREMBO kits or perhaps another brand? I am a BREMBO dealer, for motorcycle parts, but I can order up anything that BREMBO makes for auto, motorcycle etc. Looking for feedback as well, thanks!

My 99 has drum brakes on the rear. I would prefer to change them to disc if a good package/price was available.

Oh yeah, my 03 has disks on all 4 corners. Now I get it with the rear upgrade question... Anyways, I will be going to some larger dia rotors all the way around sometime once I figure it all out.

Bevl Hvn--you're right, Brembo does offer brake upgrade kits for our trucks; they have a partial kit (14" rotors, pads, and--I think--SS brake lines only) and a full kit (similar to partial but also includes larger 4-piston calipers; there is also a 15" full kit--front only--which comes w/ either 4- or 8-piston calipers).

Unless money is no object, there is at least one reason why you should consider only the front kit--on our GM NBS fullsize trucks/SUVs, the full rear kit costs almost $500 more than the full front kit...
