Installation Instructions - MAGURA HC 3 Gebrauchsanleitung

WARNING!
Ensure that the piston diameter employed is suitable for the requirements on your
motorcycle – this will generally be considered to be a piston diameter the same or slightly
larger than the original equipment master cylinder. Large changes in hydraulic ratio
may lead to poor braking performance or lack of feel. In extreme cases this may lead
to an accident. Due to the improved feel from the patented Hard Core Technology it is
normally prudent to choose a piston diameter 1 to 2 mm above the original equipment.

Installation Instructions

Due to the radial design of this master, if it is replacing an axial master cylinder, the brake line will most
likely need to be replaced. The new brake line will need to be longer and should have the ring connector
turned at 90° to allow the installation below the master cylinder. In this case please order an appropriate
new brake line separately.
Installing the Brake-fluid Reservoir.
Install the Retaining Bracket with the bolt provided M5x10
Tightening Torque = 3 Nm
Install the Reservoir Hose and clamp into position with the hose clamps provided onto both the master
cylinder and the reservoir.
Finally attach the reservoir to the retaining bracket
Tightening Torque = 3 Nm (see pic.3 on page 15)
WARNING!
Depending on your location in the world the regulations may vary with regards to the
legal requirements for brake fluid reservoir volume. The reservoir provided is supplied
for sports riding and is suitable for all applications where the brake pad wear does not
exceed a brake fluid volume of 36 ml. In the event that your motorcycle employs a twin
6 piston calliper configuration the reservoir may not meet the legal requirements in
your country. MAGURA cannot accept any responsibility in the event that this reservoir
does not meet any local legal requirements. We supply the reservoir for track use and
can confirm that it meets all of our internal requirements for a brake fluid reservoir. The
responsibility with regards to all legal requirements regarding your motorcycle remains
firmly with the vehicle owner.
Install the HC³ master cylinder on the handlebar and hand secure the clamp retaining bolts. Adjust the
position of the master cylinder to ensure that the hand lever can be operated fully to the handlebar grip
without contacting the throttle housing or switch unit. Secure the master cylinder by tightening the
clamp retaining bolts in the following sequence – We recommend a safety gap of 15-20 mm to all fairing
components.
Top Bolt (T30) fixed securely to clamp = 5.7 Nm
Bottom Bolt (T30) with gap at clamp = 5.7 Nm (see pic.1 on page 15)
