GKTech - HFM.Parts BM57 Brake Master Cylinder - RHD - HFM-NISS-BRK-00024-A

The HFM.Parts BM57 Master Cylinder features a 17/16 inch (27mm) piston bore size and is suited to both ABS and Non-ABS setups.

Perfect for if you intend to increase your braking performance and reduce that spongy pedal, giving a shorter, firmer pedal.

NOTE: The brake lever switch is a square plug, if your current one is different it will need to be modified to suit.

NOTE - If you have ABS you will need to block either the front most(closest to booster) or middle port (as they are the same port just split in two) with the provided tapered grub screw.

My brake lines feed from the top/bottom, can I still use this Brake Master? Yes. Although our brake master is designed with side ports, most brake lines can be massaged around until they reach the brake master’s ports. The fluid sensor connector is on the wrong side, what can I do? You can easily swap the sensor connector to either side of the BM57 by following these steps. On the terminal side, push a small flat screwdriver in between the sensor connector and the bottom of the reservoir to lightly pry apart the lock tab. On the opposite side of the sensor connector, push through to pop it out. This is much easier to do prior to installation! What is the thread pitch & flare on the outlets? The outlets use an 10x1 thread & ISO bubble flare with a 45deg taper or you can use a banjo fitting as the surfaces are machined.
