So my truck has looked like this for about a month since my 10 bolt took a dump.



Knowing this would happen eventually I had picked up a rusty old 14 bolt semi about 3 months prior that came with a matching front ifs and 4.11 for $100. (4.11 for sale BTW)It was a good Craigslist score but not one part of the brakes was useable. So after pricing out all the new parts for the drums I decided it would be cheaper to do a disc conversion. So after some careful planning a few wrong parts and lot's of time trying to figure out what parts go with what I ended up with all this.




From a local wrecking yard I got twin piston calipers and brackets of a 02 Escalade. The brackets have the same bolt pattern as the 14 bolt and with the use of a a spacer I machined myself they bolted together perfectly. The rotors are summit brand and the pads are EBC green stuff. Ordering the rotors and pads can get trickey due to the way some parts stores list out the options. I used 13" rotors that are 3 3/4 overall height and 2 piston calipers. The other option is 12.8" rotors that are 3 23/64" Overall Height and single piston calipers.





The only part of the swap I didn't like was the position of the caliper brackets. There is no left and right to them so you have to rotate them to put the caliper in the correct location but this puts the parking brake in mismatched position. I chose to put the caliper on the backside of the axle. This was all good for the drivers side the parking brake came out level at 6 o'clock. But the passenger side the the parking brake cable comes out straight towards the ground. I could get around this by rotating the caliper 90 degrees counter clockwise but then it would be down low at 8 o'clock. This thing sees mud and I wasn't to keen on a caliper down in the mud. The other option would be 90 degrees the other direction . This would make it a mirror image of the drivers side with the caliper on the front side of the axle and the ebrake cable exiting the towards the rear. This would probably be the best but it puts the bleeder screw at the bottom. You could buy a second left side caliper to solve the problem. With all that being said I didn't do any of it. I left the drivers side good where it was and the pass. side with the cable pointing down. I spent enough money on everything else I wans't going to get a new caliper.




And this would definatly not work with 15" rims I have 16" classic 2's and the is about 1/4" of clearence between the rim and caliper.

The end of the ebrake cable is also different. I haven't tackled that yet but have a pretty good plan on what to do.



I also did a u-bolt flip 5.13 gears and a trutrac while I was at it.

Sorry if this I too long but I wanted to include some of the details for people thinking of this swap. ]]> Axles + Brakes GTAmazing http://www.gmt400.com/forum/showthread.php?1856-13-quot-NBS-rear-disc-on-14-bolt-SF http://www.gmt400.com/forum/showthread.php?1845-got-a-wobble....need-help-figuring-out-what-it-is....&goto=newpost Fri, 03 Sep 2010 14:41:07 GMT alright started about 2 days ago...when i am driving...and you really cant feel it till you get about 45 or 50 since my shocks are shot....you can... alright started about 2 days ago...when i am driving...and you really cant feel it till you get about 45 or 50 since my shocks are shot....you can feel it in the steering wheel but it feels like the driver side tire is wobbling....what could cause this? ball joints? unbalanced tire? i havent checked the pressure in the tires but its not like a flat tire feeling wobble...TIA:hmm: ]]> Axles + Brakes jshawag12 http://www.gmt400.com/forum/showthread.php?1845-got-a-wobble....need-help-figuring-out-what-it-is.... http://www.gmt400.com/forum/showthread.php?1840-Need-help-with-tire-size!!&goto=newpost Thu, 02 Sep 2010 23:08:33 GMT Hi, I was wondering if anyone knows what are good tire choices/sizes for a 15x10 rims.

I feel so much more confident stopping his 7000 lb truck than my (maybe) 5000 lb suv. I don't see how it could have bigger rotors or calipers because the wheels are 16' on both.

I am starting to notice at stoplights and such, that when I hit the gas to take off, I feel a jerk. You know, the type of jerk that normally you'd hear a clunk to go with it, but I'm not hearing anything when this happens.
It feels like when you go to take off and hit the gas there's nothing for a split second then you feel a jerk and the truck starts moving.

I don't know if its my trans (works fine in every other way), or my u joints, or my rearend. How would I check my rearend for slack with out taking it apart?

Turns out my problem was kinda hard to describe, so I hope it makes sense, if anyone knows what could be causing this please let me know, thanks. ]]> Axles + Brakes frito-bandito http://www.gmt400.com/forum/showthread.php?1793-Driveline-Question-something-aint-right... http://www.gmt400.com/forum/showthread.php?1792-brake-line-size&goto=newpost Sat, 28 Aug 2010 18:58:35 GMT Hey, anyone know what size the steel line going to the back of the truck is, 3/16 or 6mm?

I know everyone uses the caddy setup. But I like to look as stock as possible so I can get upgrades without major work a 2nd time. I have come across the 2k+ s10 blazers with rear discs. I was wondering if anyone has tried this yet with the impala rotors. According to all measurements it should bolt up, also when I am ready this will make upgrading to c6 rotors and calipers very easy as the dimensions match with just replacement of rotors, calipers and caliper bracket. If anyone can confirm the bolt on of the hub to the rear axle with maybe a 1/4" spacer, I may have found a cheap avenue into this venture.

Just trying to get some information for my 97 rcsb before I do my major engine work. Want all my suspension and brakes setup just right so I can keep up with those sports cars in the turns. ]]> Axles + Brakes NoLoveRacing http://www.gmt400.com/forum/showthread.php?1757-So-I-have-been-researching... http://www.gmt400.com/forum/showthread.php?1743-14ff-brake-locking-up&goto=newpost Sat, 21 Aug 2010 05:07:32 GMT it started this monday, when i start the truck(everytime) and go, the first time i touch the pedal the left rear wheel locks up. then after that it... it started this monday, when i start the truck(everytime) and go, the first time i touch the pedal the left rear wheel locks up. then after that it only does it when the tire loses traction i.e. tire is in dirt or the truck flexes. works fine as long as it has traction or the truck is level.
