The "Tan Brick" aka my 1997 Express Cobra conversion

The lever (green arrow) is part of a spring wound around the cable take-up. The lever contacts the stop (blue arrow) when the brake pedal is released. This causes the spring to "unwind" slightly and release the take-up. The take-up is spring loaded and attempts to "wind up" the cable and take up slack. When the pedal is pressed the lever moves off the stop, the spring around the take-up contracts, and the take-up is held tight so the park brake can be applied.

So it looks like I need that K30 parking brake pedal assembly and the instructions on how to make it work. The parking brake has never applied very well on this Express. In fact if you set the parking brake, put the trans in gear, at anything above idle speed the van will move with the brake set.

The G30 cable needs to be cut shorter to work with the K series pedal. On the actual cable are two crimped steel "beads." One is at the end of the cable, the second, a larger rectangular bead, is about 4" - 5" from the end. We cut the "extra" 4-5" off the end and insert the larger rectangular bead into the new pedal. Red arrow shows bead... it must be cut in half.

GMC offered "2500" vans for upfitters for years that had few observable differences from the half ton cousins.

Let me see if I follow. I bet the G1500 cable is the same, atleast on the pedal end. The K30 (Is this the HD truck or your normal K3500 4x4) pedal bolts right on, cut the extra off the cable by cutting that rectangular bead in half.

I know they offered those. While they are extremely rare, I have seen a couple of conversion vans on G3500 with 454s and 8100s. Most notable one I can remember was sent to Quigley first for a 4wd conversion then went to a high end conversion company. 8100 + 4x4 + Conversion and was pretty tricked out.

I looked up a pedal for a 1999 K30 on Ebay, couldn't find one, but found a listing for a K3500. List to be the same pedal from 96-99 in the OBS trucks. I think I have one of these left over from the 1999 K1500 Suburban we parted out.

Sorry. I had to run off to a prior appointment.

Yes. The K30 was a normal truck.

They probably are the same in all C/K trucks in those years. We had a K30 here to borrow a pedal from on the day we were trying the first swap, so I always ordered a new pedal for that vehicle.

That 4WD conversion van sounds cool. I once found a Quigley conversion bus at a reasonable price but no matter how I tried I couldn't get upper management to go for it.

No problem! I got busy with work as well.

It was threatening rain this evening and the mosquitos are worse. Even Deep Woods OFF was not stopping their thirst for my blood. I only managed to get the wiper cowls fitted. I found a battery terminal puller makes getting the wiper arms off a breeze.
