Heavy-Duty 30/30 Spring Brake Chamber for Semi Trucks

A spring brake chamber is an essential part of a commercial vehicle's air braking system. Combination spring brake chambers perform two important functions:

• Service Braking: Compressed air acts on the service diaphragm to apply the foundation brakes during normal braking.
• Parking and Emergency Braking: A powerful internal spring applies the brakes when parking-brake release pressure is removed or insufficient.

The Power Products 3030SB is intended for compatible heavy-duty trucks and trailers equipped with Type 30/30 standard-stroke spring brake chambers.

Potential applications include:

• Class 7 and Class 8 semi trucks
• Commercial truck tractors
• Heavy-duty trailers
• Vocational trucks
• Dump trucks
• Fleet maintenance vehicles
• Other compatible air-brake-equipped commercial vehicles

Important: Fitment must be confirmed by the original brake chamber specifications, mounting configuration, pushrod requirements, and stroke designation. Vehicle make and model alone do not guarantee compatibility.

Gold Epoxy Coating for Corrosion Protection

The Power Products 3030SB features a gold epoxy-coated steel housing designed to help protect against corrosion caused by road moisture, dirt, and harsh operating environments.

Its return and power springs are also epoxy coated, providing additional protection for internal spring components. This construction makes the chamber a practical choice for commercial vehicles exposed to demanding road conditions.

Reinforced Mounting Studs & Protective Dust Shield

Secure mounting and contamination protection are important to long-term brake chamber performance.

The 3030SB brake chamber incorporates reinforced mounting studs to improve rigidity and help prevent mounting-related damage. Its protective dust shield helps reduce the entry of road dirt, sand, and moisture.

Standard Stroke vs. Long Stroke Brake Chambers

The Power Products 3030SB is a standard-stroke Type 30/30 brake chamber with a nominal 2.5-inch maximum stroke.

Standard-stroke and long-stroke chambers are not automatically interchangeable. Long-stroke Type 30/30 chambers may have different travel capabilities, identification markings, and application requirements.

Do not substitute a standard-stroke chamber for a long-stroke chamber. Always verify the required stroke type before ordering.

Signs of a Failing Spring Brake Chamber

Brake chamber problems should be inspected promptly because they can affect commercial vehicle braking performance.

Common signs that a brake chamber requires inspection or replacement include:

• Air leakage around the brake chamber
• Failure to release the parking brakes correctly
• Abnormal brake chamber pushrod movement
• Corrosion or visible damage to the chamber housing
• Damaged mounting studs or mounting hardware
• Brake application or release problems
• Failed air brake system inspections

Inspect the complete braking system to determine whether the issue is caused by the chamber, air lines, valves, slack adjuster, foundation brake components, or another related part.

Installation & Fitment Verification

Before installing the Power Products 3030SB, verify the original brake chamber size, stroke designation, mounting stud spacing, pushrod length, clevis configuration, and all applicable vehicle brake system requirements.

Brake chamber pushrod length and adjustment must be determined according to the manufacturer's service procedure. Do not assume the replacement chamber can be installed without checking the complete brake linkage geometry.

Critical Safety Warning: Spring brake chambers contain a powerful compressed spring that can cause severe injury or death if improperly handled. Never cut, open, or attempt to disassemble the sealed spring brake housing. Follow the manufacturer's approved caging, removal, installation, and testing procedures.

Professional Installation Required: Commercial vehicle air brake systems are safety-critical. Installation, inspection, and adjustment should be performed by qualified technicians following the vehicle and brake manufacturer's instructions.
