DescriptionThe whole story▼

The MP006 is a pedal-operated rear brake master cylinder built with its fluid reservoir integrated into the unit itself, rather than requiring a separate tank to be plumbed in. It uses the larger 13.5 mm piston and a 15 ml tank capacity, and the reservoir cover, also CNC-worked aluminium, is offered in seven colours: black, blue, gold, green, orange, red and silver, letting the cover be matched to the rest of the motorcycle. Unlike the MP005, this is a standalone pedal master cylinder rather than a double-connection unit for combining controls.

Key Features

  • 13.5 mm piston diameter for a firmer pedal-operated rear brake
  • Fluid reservoir integrated into the body, 15 ml capacity
  • Reservoir cover available in seven colours to match the motorcycle
  • CNC-worked aluminium body with a black hard oxidation finish
  • 10 mm brake hose fitting with a 40 to 50 mm hose-fixing distance
  • Made entirely in Italy to Accossato's own tolerances
  • Not recommended for use together with a thumb brake master cylinder on one circuit

Construction and Material Quality

The main body is CNC-worked from aluminium and finished with a hard, black surface oxidation treatment, machined around the 13.5 mm bore to the same tolerances as the rest of Accossato's rear brake range. The reservoir is built into the casting rather than mounted remotely, which keeps the fluid circuit compact and removes one set of hose connections that a separate tank would need. The cover over the reservoir is a separate CNC-machined aluminium part, available in seven finishes, while the hose-fixing distance stays at 40 to 50 mm and the brake hose fitting at 10 mm, matching the other 13.5 mm units in the range.

Integrated Reservoir and Cover Colour Options

Building the reservoir into the master cylinder itself means the fluid tank moves and vibrates with the unit rather than as a separate component on its own bracket, which can simplify routing on a tidy rear brake installation. The 15 ml capacity is sized for a rear brake circuit of this piston size, and the seven cover colours let the finishing touch of the unit match paintwork, anodised parts or other coloured components on the motorcycle without affecting the hydraulics underneath. As with the MP001 and MP003, Accossato does not recommend mounting the MP006 together with a thumb brake master cylinder on the same circuit; riders wanting both a pedal and a thumb or hand control should use the double-connection MP005 instead.

Fitment and Compatibility

Accossato publishes no motorcycle fitment list for the MP006; as with the rest of the pedal-operated rear brake range, it is a universal part rather than one matched to a named model. Before ordering, check the 40 to 50 mm hose-fixing distance and 10 mm hose fitting against your own rear brake lines, confirm the 13.5 mm piston and 15 ml reservoir are right for your rear brake system, and pick the reservoir cover colour that suits the rest of your motorcycle.

Road Approval

This master cylinder is not supplied with German road-approval documentation; it is intended for off-road, competition and adaptive hand-control use.

Scope of Delivery

The package includes the Accossato MP006 rear brake master cylinder with the integrated 15 ml fluid reservoir and the reservoir cover in the colour selected, in black CNC-worked aluminium. The brake hose is not included and must be sourced separately.
