Hello dear truckers,

I have a similar problem.
On my last trip I had less brake power on the front axle.
I took the drum down and saw that the wheel brake cylinder is leaking.
Now I want to change all of them. There are two cylinders per side, top and bottom installed.

But as always I have problems finding.
I saw some at Rockauto that should fit visually. However, the description says axle load.
Cylinders for 7000 pounds, 9000 pounds and 11000 pounds.
Unfortunately I do not know what I have mounted for an axle. It is a 1966 Chevrolet c60, 6.0 l 366 cui (Firetruck).
I took pictures of the cylinders (The start number is the same, the end numbers are different). Unfortunately I can't get any further with the numbers.
I hope again for the best forum.

Greetings from Germany

Brian
