Front Brake Master Cylinder for SUZUKI GN125H
SUZUKI GN125H Front Disc Brake Upper Pump 59609-H05300H-000 is supplied against OEM reference 59609-H05300H-000 for SUZUKI GN125H. The front brake upper pump is the master cylinder at the handlebar: it converts lever travel into hydraulic pressure, and a worn bore or seal shows up as a lever that slowly sinks under steady pressure. Our front disc brake upper pumps are made of high-quality materials, with stable performance and long service life. The minimum order is one piece, packed neutral or under your own brand, with ISO9001 certification.

What the Part Is Built To Do
- Bore sized to the original master cylinder
- Reservoir and cover to the OEM pattern
- Outlet thread matched to the standard banjo bolt
- Individually packed
Symptoms That Point Here
- Lever slowly moving to the bar under constant pressure
- Fluid weeping at the lever pivot or the reservoir cover
- Spongy feel that does not improve after bleeding
- Brake dragging because the return port is blocked
How It Compares With the Alternatives
Compared with rebuilding the original with a seal kit
A rebuild only works if the bore is still smooth; a pitted bore will cut new seals within weeks.
Compared with a universal master cylinder
Bore size changes lever feel and braking balance, and the banjo thread may not match your hose.
Fitting and Service Notes
- Use fresh fluid of the grade marked on the reservoir cover and never re-use fluid from an open bottle.
- Bench bleed the cylinder before fitting where the design allows it.
- Keep the reservoir level while bleeding so no air is drawn in.
- Check the lever returns fully and the brake releases before the first ride.
