Which line? The factory lines from the truck, van or Tahoe?

The 2WD coils spring 1500 trucks have a rack and pinion. The Factory 2500 hydroboost lines From a Hydroboost truck will fit but require some re-shaping.

Resurrecting for a sec here.

About to do this upgrade on a 2003 1500.

I see the rotors, calipers, pads, etc. and it all seems to make sense to me except for caliper brackets. Do I need to change the brackets as well to accommodate the larger rotors (thickness and diameter) or is that all handled by the calipers?

Also I have a whole hydroboost setup I got from a user here but I think I am lacking the pedal(s). Is it different enough that I should seek out a hydriboost pedal?

Lastly, I am shopping for the braided lines and I seem to keep finding line "sets" that only picture two lines. Is there a set with all 4 out there or do I need to be thinking separate front and rear sets?

I apologize for the relative newbie questions but the truck GM/LS platform is new to me.

Thanks!

Yes you need the new caliper brackets.

Yes you need the hydroboost pedal. You could maybe modify the stock one if you know how to weld, but for $20 for the pedal it's not worth it.

Yes Russel makes a 4 line kit.

FWIW my new 2015 1/2 ton(dual front caliper single rear caliper) stops better and better pedal pressure than any vehicle I have ever driven. Better than wife's 2002 Avalanche with dual rear calipers.

Thanks to everyone for the knowledge and experience with this upgrade, this thread has been a great help. I just picked up Raybestos PPV calipers for all four corners and Raybestos R300 rotors for my 2000 Z71. I'm having the calipers hydrodipped but before I got carried away, I decided to mock up the new stuff tonight. Everything checked out up front but the rear caiper braket did not align with the mounting holes. After digging a little bit further, it appears there are multiple options for the rear 2 piston caliper. My parts / research:

UPDATE: Looks like I have two sets of front calipers... somehow got the fronts instead of rears for the SUV upgrade. LOL.

FRONT
Rotors: Raybestos 580279PER
Calipers: Raybestos PPV calipers RC11714P / RC11713P

REAR
Rotors: Raybestos 58015PER
Calipers: Raybestos PPV RC11885P / RC11886P (if I can find them)

I also thank the folks in here for this great info. Saved me a lot of time and experimentation. Good stuff.

I ended up with a whole rear setup pulled from a 2005 Tahoe--seemed to fit fine-- and then the Stoptech KC2067-36 kit(330mm/13" front from from rear-drum truck) was offered through Amazon for $350 with free shipping so I splurged a little. I honestly didn't want the drilled/slotted rotors as they advertise a little visually but I figured I would give them a try.

I ordered the Russell 672470 from Summit which was a little pricier than I expected but not out of this world.

Next, I have a hydroboost setup in a crate somewhere I was saving for the Jeep but I think I might put on this truck as it will allow me to familiarize myself with the setup and know what will work out of the box and what will need work on that project.

Hopefully I will be putting myself through the windshield with the brake pedal soon.

Are you guys finding that it is worth running a premium or super premium brake fluid in these trucks or just good name brand from the parts store?

Thank you.

Update--

Guess I got what I wished for. Powerstop sent me two passenger-side rotors(different slotting; not side-specific from OEM). I didn't have patience for them and had some AutoZone points and coupons to burn so I picked up the Duralast Gold rotors(the black-coated "high carbon" pieces) and Duralast Maxx pads. Paid about $75 for each rotor and $50 for the pads before discounts and such. Just wanted to get it back on the road. I am going to send back the rotors and pads for a partial refund that hopefully equals about what I have in the Autozone parts. So I've got plain rotors albeit big ones.

This is the best-stopping truck I have ever experienced. I could not get the brakes to make a single bit of noise, stops over 60 were shorter than many typical non-performance cars I've driven and below 30MPH I don't feel like there was more than a truck length or two of stopping distance if I hung on and really laid into it. And this was on wet pavement. Guess the ABS was doing its job also.

I was previously considering wasting a hydroboost setup on this truck..I only say waste because it just isn't necessary for regular or aggressive driving I think.

Thanks again for those who did the work on this one. Very high bang-for-buck factor here.

Unless your ABS is activating every time you slam the brakes there is always room for improvement.
