Heavy Duty Knorr Type Disc Brake Caliper Complete Mechanism Repair Kit for SL7/SM7/ST7

This heavy-duty Knorr type repair kit is made for SL7, SM7 and ST7 disc brake calipers, used to service and restore air disc brake calipers on commercial trucks and trailers. It comes with all the key internal parts needed to fix the caliper’s adjusting mechanism, getting worn or faulty brake calipers back to normal working order.
During daily use, disc brake calipers are always exposed to high heat, heavy load pressure and environmental dirt. As time goes on, internal parts like the adjusting mechanism, gears and wear components can lose accuracy or get stuck—this leads to uneven braking or weaker performance. This repair kit lets you replace those critical internal parts without replacing the entire caliper, making maintenance much more cost-saving.
It’s widely used in Knorr-type SL7, SM7 and ST7 brake systems, which are common on heavy-duty trucks, trailers and fleet vehicles. These vehicles are often used in long-haul transport, construction and logistics. The kit is especially handy for repair shops and fleet maintenance teams that need quick repairs and less vehicle downtime.
Every part in the kit is made to match OEM standards, so it fits perfectly and works smoothly after installation. It’s a complete repair solution that brings back consistent braking performance and extends the service life of the caliper.
