Knorr Type Disc Brake Caliper Repair Kit Adjuster Spindle KBCP004

This KBCP004 adjuster spindle repair kit fits Knorr-style air disc brake calipers, perfectly suited for routine overhaul and part replacement on heavy-duty trucks and trailers.
As a core drive component inside the brake caliper, the adjuster spindle governs the travel range of brake pads. It precisely balances the spacing between brake pads and brake discs, keeping the whole braking system well calibrated at all times.
Vehicles that carry heavy cargo and make frequent stops place continuous strain on brake assemblies. The spindle will gradually suffer surface wear and flexible sensitivity decline after long service hours, easily causing jittery braking, lagged pedal feedback and poor fitting between pads and discs.
This KBCP004 full repair kit offers a targeted replacement solution. It renews the aging spindle and matched accessories, effectively recovering the caliper’s original adjustment precision and making daily fleet maintenance more economical and efficient.
