Knorr Type Commercial Vehicle Disc Brake Caliper Repair Kits Caliper Tappet-69mm

The Knorr-type disc brake caliper repair kit, featuring a 69mm tappet, is made for servicing air disc brake calipers on commercial vehicles—like trucks, trailers, and buses. The 69mm tappet is a key moving part inside the caliper; its job is to transfer force and keep the brake pad in tight contact with the disc.
During long-term use, the internal parts of the caliper are exposed to heat, friction, dust, and constant heavy loads. Over time, the tappet can wear out or get stuck, which might cause uneven braking, slower response, or uneven pad wear. This repair kit solves that problem perfectly—you can replace the worn parts directly, no need to change the entire caliper, saving time and cost.
It’s widely used in Knorr-type braking systems on heavy-duty transport vehicles, ideal for fleet maintenance and workshop repairs. The 69mm size ensures it fits the corresponding caliper models, helping restore stable braking performance quickly after replacement.
