⚡ At a Glance
- • Brake Fitment: Direct replacement for many Chinese-made dirt pit bikes, intended for rear-wheel brake setups
- • Best for: Owners and mechanics working on 50cc–200cc Baja, Apollo, Taotao, Roketa, Sunl and SSR pit bikes
- • Not ideal for: Machines with non-standard caliper mounts or rear-wheel shaft sizes outside common pit-bike dimensions
Rear master cylinder and caliper assembly designed for popular Chinese pit-bike platforms. Fitment aims to simplify rear brake swaps and routine maintenance.
Secure alignment - with an adjustable linkage rod and wide mounting range
Linkage rod length is 110mm and can be adjusted by about 10mm either way, while mounting hole centres accept 40mm to 50mm centre-to-centre. These dimensions allow minor frame and caliper position variations to be accommodated during installation.
Easier alignment at installation reduces the need for aftermarket adapters and minimises trial-and-error adjustments at the workshop.
Ready to fit faster - with a fitted brake pad plus spare pair included
Package contains one rear brake master cylinder assembly with a brake pad pre-installed and one extra pair of spare brake pads included in the box.
Immediate replacement is possible without sourcing pads separately, cutting downtime and avoiding an extra parts run.
Practical routing and compatibility - thanks to common brake line length and shaft support
Brake line supplied is 50mm in length (about 19 inches) and the assembly is compatible with both 12mm and 15mm rear wheel shafts, noting a small gap when used on 12mm shafts that does not affect operation.
Simplified brake-line routing and broad shaft compatibility reduce trimming or custom fabrication on typical pit-bike frames.
