Description
TYPE 30 SPR.BRK.-TDM
Part Number: F3030TSC
Direct replacement (cross ref) for 3030-TS.
Product Overview
This Type 30 spring brake chamber is part of the truck’s air brake system and handles both service braking and parking brake operation. It replaces OEM part 3030-TS and is commonly used on heavy-duty truck and trailer applications. When these chambers start failing, you usually notice brake issues pretty quickly: weak braking, air leaks, or problems releasing the parking brake.
Brake chambers deal with constant pressure cycles, moisture, vibration, and road grime, so they wear out over time just like any other brake component.
What the Part Does
The chamber converts air pressure into mechanical force to apply the brakes. Inside, there’s a service diaphragm and a heavy spring section for parking brake function. When air pressure drops, the spring brake engages automatically.
A properly working chamber keeps brake application smooth and predictable. It also helps maintain safe stopping distance and proper parking brake operation.
This part works closely with components like the Automatic Slack Adjuster and clevis connection in the brake linkage.
Common Problems This Part Solves
A failing spring brake chamber can cause:
- Air leaks around the chamber
- Weak or inconsistent braking
- Parking brake not releasing properly
- Slow brake response
- Visible corrosion or diaphragm failure
Sometimes drivers hear constant hissing near the axle area. In colder weather, moisture inside the system can also speed up internal wear.
Why Replacement Matters
Brake chambers are not something to ignore. If one fails completely, the truck can become unsafe to operate or end up out of service during inspection.
Replacing a worn chamber restores proper brake function and prevents extra strain on other brake system parts. It’s also much cheaper to replace a weak chamber early than to deal with uneven brake wear or damaged components later.
Compatibility and Fitment
This aftermarket chamber replaces OEM part number 3030-TS. Always verify chamber size, mounting style, and air line configuration before ordering.
Correct chamber sizing matters because brake force and pushrod travel depend on it.
Installation and Service Notes
Brake chambers contain heavy internal spring pressure and should be handled carefully. The system must be fully depressurized before service.
During installation, inspect the slack adjuster, clevis, air lines, and mounting hardware. If the old chamber failed because of corrosion or contamination, nearby components should also be checked.
After installation, verify pushrod stroke and brake adjustment.
Use Case
Commonly used during brake overhauls, air system repairs, and fleet maintenance work on trucks showing brake imbalance, air leaks, or parking brake problems.
