Upgrade Motorsport Spherical Bearing Mount Master Cylinder - .625 Bore, .7 Bore & .75 Bore - Remote Reservoir Fitment
0.625" Bore Upgrade Spherical Bearing Mount Master Cylinder
Best for lightweight cars and applications where maximum pedal feel and fine modulation are required. Ideal for drift handbrakes, rear brake circuits, lightweight kit cars, and track cars where control is more important than outright pressure.
0.70" Bore Upgrade Spherical Bearing Mount Master Cylinder
A great all-round option offering a balance between pedal effort and fluid displacement. Well suited to dual-purpose road and track cars, rally builds, and balanced brake systems where predictable response is key.
0.75" Bore Upgrade Spherical Bearing Mount Master Cylinder
Designed for higher fluid volume and firmer pedal feel. Best suited to heavier vehicles, larger calipers, competition braking systems, and hydraulic handbrakes where rapid pressure build-up is required.
All Upgrade Motorsport spherical bearing master cylinders are precision machined for strength, consistency, and reliability under hard use.

Upgrade Motorsport Push Type Master Cylinder suitable for use in brake or clutch applications. The body is constructed from hard anodised aerospace grade aluminium to provide high strength and light weight.
The cylinder pivots on a 8mm I/D high grade spherical bearing to allow it to rotate with the arc of the pedal and the offset of the balance bar, minimising side loads on the piston seals.
Small compact and incredibly lightweight design allows installation into tighter envelopes, still utilising all the quality and performance techniques required to withstand the challenging world of motorsport.
