    New brake pad edge scraping rotor

    Gold rotors should work out fine. The Centric 125.66009 are also very nice as they have a milled surface which really speeds up the bedding process.

    Maybe you got the pads for the 1ton??? They still clip in, but are larger overall.

    swap/upgrades to front calipers

    Just swapped out by JB6 equipped 1995 Yukon with JB7 3.15 Front Calipers and 1.25 Master as the pedal feel is much improved thanks mostly to getting rid of the low drag calipers and quick uptake master. Takes a little more effort but it's well worth it. Still running stock booster. The rear...

    JC Concepts GMT400 RC Body Including Snoop Nose!!

    Anyone build an RC Crawler or Monster truck using one of these GMT400 bodies?? The 11" body on a HPI Wheely King or King Crawler would be sweet or even using a MST CFX crawler kit. The Snoop Nose is really killer...i remember these as a kid...

    Master Cylinder Upgrade?

    If you are going back, why not try a JB7 master as it uses the same booster and you don't need any adapters. Then upgrade to the non-low drag 3/4 1 ton calipers.

    Anyone else force shifts by slightly lifting gas pedal?

    ?? While accelerating I let the gas pedal lift about 1/8 to force a shift. Seems like this is much better for trans. I've owned 4 GMT400s and have racked up close to 700,000 miles on them and had zero trans issues. All i have done is extracted 4 quarts of trans oils every 30,000-40,000 miles...

    Frozen Rotors Blank or Slotted

    Looking to purchase some Cryo rotors as mine are about past there prime...put over 80,000 hard miles on them and they can no longer be cut. I purchased these from Praise Dyno years ago and i see they are out of business. Any suggestions? I see Frozen Rotors.com but not sure they are the way to...

    JB5 JB6 JB7 JB8 Size Thread

    I thought of that also. I averaged 12.7 before the swap. I'll start recording my MPG again. My quess is that they didn't use low drag calipers on the 3/4 & 1 ton because the EPA doesn't require the MPG to published.

    JB5 JB6 JB7 JB8 Size Thread

    Should have come this way from factory. Well worth the effort. Put on about 90 miles today and they work great. Heat cycled them a few times and rear just starts to lock up when they are hot....but not full lock up. Although this might be due to my rear drums being warped. Trying to sort this...

    JB5 JB6 JB7 JB8 Size Thread

    I have 1995 and it uses the 4WAL Anti-Lock system. Just changed out MS to a JB7 series without the quick uptake and JB7 calipers and the pedal is rock hard...crazy amount of difference. The bench bleeding took about 1hr and found the trick was to push the cylinder at different angles and for...
