Air Brake Repair Sacramento — Commercial Truck & Semi Trailer Brake Service

AIR BRAKE REPAIR — standard BRAKES

Air brakes on commercial trucks and semi trailers are fundamentally different from the hydraulic brakes on standard vehicles. The air compressor, air lines, brake chambers, slack adjusters, and ABS systems require specialized knowledge, tools, and diagnostic equipment. 916 Truck Repair specializes in heavy-duty air brake systems for Class 8 commercial vehicles.

Our air brake repair service is mobile — we come to your truck for brake diagnostics, adjustment, and repair. No towing required for most brake issues.

AIR BRAKE SERVICES

Air Brake Diagnostics

Air leak detection, brake chamber testing, slack adjuster inspection, compressor performance testing, and ABS fault code reading. We diagnose the root cause of brake system problems.

Brake Chamber Replacement

Service brake and spring brake chamber replacement. Mobile installation with proper pushrod stroke adjustment and system testing.

Slack Adjuster Replacement

Manual and automatic slack adjuster replacement. Critical for maintaining proper brake stroke and DOT compliance.

Air Brake Adjustment

Brake adjustment to restore proper pushrod stroke and braking force. Regular adjustment prevents brake fade and ensures consistent stopping performance.

ABS Brake System Repair

ABS ECU diagnostics, wheel speed sensor replacement, modulator valve service, and trailer ABS repair.

Air Compressor Repair

Air compressor diagnostics, unloader valve service, and governor adjustment. The compressor is the heart of the air brake system.

Air Dryer Service

Air dryer cartridge replacement and desiccant service. Moisture in the air system causes ice formation in cold weather and corrosion year-round.

Brake Line Repair

Air line repair and replacement. We fix leaks in the air system from the compressor to the brake chambers.
