I just recieved the newest shop tour video and am trying to figure out the air brake shrinker of the Carter's in the beginning. I have an air brake off of a semi which is twice the size of theirs and has two fittings. One of the fittings lowers the piston and one raise it.Do I need to install a one way releif valve so the air goes in when I depress my pedal and goes out the valve when I release the pedal? Is there a simpler way that I can't see?I don't know how this brake is buuilt inside so I'm at a bit of a loss. Did they maybe cut theirs down and rig up a different type of valve? If you know or if you are one of the Carters please e-mail me at bugger130@mindspring.com I would also love to see ( buy )some plans for newest plannishing hammer of Stans.

Thanks all, Scott

Hi Scott:
From what you are describing, it sounds like you have a Spring Chamber Air Pot. These are the drive axle air chambers and incorporate the parking brake chambers and the road brake chambers. A word of caution! Unless you are familiar with air brakes DO NOT try to disassemble the pot without first caging the brake spring!
THe chamber that we use to power shrinkers and such are the single chamber units used on the steering axles. They are relatively inexpensive and should be available at any truck part distributor. Single Chambers come in a variety of sizes from 4" to 8" and larger. I think 6" is common for shrinkers but am not sure. Maybe one of the guys with that set and can tell us?

Stans set- up uses a common #24 {6"]Brake can . Truck supplies have them. I Paid $26.00 for mine . his lever ratio puts it at 7200 pounds of force at 100PSI it will do 16Gauge M.S. .He warned me of the limit , i fired mine up and broke off the finger which pushes the die down {haven't found it yet , i made a new one} "good low-dollar get worken metal"Tool .
Stans a Clever Man , the things he comes up with just unbelieveable . Strand him and Jim Bailie on an Island ,they will build a ship in 2 days to get home .
