Inside the canister is a spring and a pancake like a brake chamber.. the spring is broken. The mechanic tells me it’s air over hydraulic… I don’t know… never seen anything like it. The van is in excellent condition everywhere else but sadly I’ve spent $2000 dollars on replacing everything brake...
I wish I knew. Turtle top did the conversion, they said they don’t mess with anything but the body. Chevrolet says they don’t list anything either. No stickers or stamps inside the doors or anywhere I can find.
My 98 3500 has air over hydraulic brake system. I need the single brake chamber in the rear. I’ve never seen a setup like this nor my mechanic. Chevrolet can’t help nor Turtle Top who did the body conversion.
