Nissan Cabstar Front Brake Caliper Repair Rebuild Kit 48mm (1998 - 2006)

Nissan Cabstar Front Brake Caliper Repair Rebuild Kit 48mm (1998 - 2006)

Engineered specifically for the heavy-duty Nissan Cabstar (1998 - 2006 / TL Chassis) light commercial truck and cab-over lineup, this premium 48mm Front Brake Caliper Repair Kit is designed to eliminate hydraulic fluid leaks, resolve caliper seizing, and overhaul sticking front brake piston mechanisms.

Composed of high-grade, heavy-duty rubber seals and protective dust boots, this rebuild kit restores tight hydraulic pressure under heavy hauling conditions, resolves spongy brake pedal issues, and ensures your front braking system operates with factory-spec efficiency.

Why Should You Rebuild Your Cabstar Front Brake Calipers?

Since the front braking system handles the vast majority of the vehicle's stopping weight, the front calipers on the Nissan Cabstar endure extreme mechanical stress and intense thermal loads under daily commercial cargo duties. Over time, environmental exposure to road mud, debris, and water tears the protective piston dust boots. This allows humidity inside the housing, causing the 48mm caliper piston to rust, seize up, and drag against the brake rotor.

Common symptoms of a failing front caliper seal include:

• The vehicle pulling sharply to one side during braking due to uneven front caliper pressure.

• Steering wheel shaking or pedal vibration/pulsation during high-speed deceleration or heavy downhill hauling.

• Visible brake fluid leaks around the front caliper assembly and dropping reservoir levels.

• Excessive brake dust, burning odors, and uneven or premature wear on the front brake pads and rotors.

This 48mm piston diameter seal kit allows you to completely rebuild your existing assembly, bypassing the extreme cost of purchasing a completely new commercial Nissan caliper housing.

Key Product Features:

• Precise 48mm Fitment: Designed as an exact direct match for Nissan Cabstar front disc brake calipers with 48mm piston setups.

• Premium Heavy-Duty Elastomers: Superior resilience against heavy brake fluids (DOT 4) and extreme front axle thermal cycles from high payload transportation.

• Comprehensive Front Component Set: Includes high-quality piston dust boots, internal hydraulic pressure seals, and guide pin boots for a full service.

• Cost-Effective Engineering: Restores maximum braking safety efficiently without discarding the expensive original caliper body.

Installation Tip: Because front axle braking performance is vital for commercial vehicle safety under heavy load conditions, always apply a thin layer of specialized high-temperature brake cylinder assembly paste to the new rubber seals and the piston to prevent tearing during insertion. Perform a complete brake system bleed afterward.
