Linked Brake Disassembly

Well, the linked brake unit is a bit of a dog's dinner compared to the system on the T-series big twins. Here is the assembled master cylinder. On the right is the connecting rod that goes to the foot lever. In the middle is a hydraulic hose that goes to the brake fluid reservoir, which is under the seat, and in front of the battery. On the left is a banjo bolt that takes brake juice to the rear brake, through a normal sizes hose, and to the front linked brake via a narrow bent pipe. This pipe is formed to the shape of the frame, and ultimately connects to standard brake hose to go to the front left caliper. At the top is the brake light switch.

Rear brake caliper has already been removed, but has not yet been drained.


Undo the banjo and drain the system. A bit messy.


The master cylinder js held on by two bolts. There are captive nuts welded onto the frame.

Showing the removed master cylinder next to its mounting points:


The brake footpedal is held in place by a small split pin, which can be removed with nosey pliers to remove the foot control.


At the front of the frame, the linked front brake host and carb cables go through a grommet with loop which acts like a cable tie:


This is the junction where the thin metal pipe turns into proper brake host:



Metal brake pipe has its own fancy rubber spacers that keep it slightly away from the frame:

The flasher relay is mounted in a rubber support that mounts next to the linked brake reservoir:

Removal is easy


Note the rubber strap that holds the tank in place, and the middle piece that provides a mounting for the flasher relay
