Motorcycle Rear Brake Setup
« on: January 24, 2009, 02:23:23 PM »
This year for Bonneville I wanted to reduce the rotating weight and drag from the front brake. So I took the the front caliper and rotor off the bike. It would be tough to load and unload a bike off a pickup bed without a front brake to grab. I decided to use the front master with a long hose back to the rear caliper. Worked out fine. I would prefer to use the rear master with the rear caliper for stopping on the course and still keep the front master option for loading. Is there a way to combine the front master and the rear master with a tee connection into the rear caliper? Do I need a check valve?

You could use a standard Tee from Goodridge or earls and fit a line lock on the run from the bars to stop the back feeding of the resevoir

You could even use a thumb brake like the stunt riders use if you wanted to lose some bulk from the bars.
Just a thought.

For loading and unloading without a frt. brake....
..........put it in low gear and use engine comp. and the clutch lever.....................very simple.............

Tried that but the clutch drags just a bit too much when loading ... Joe

Put a small shut-off valve in the front brake line before you tee the front and rear lines together. Once you've unloaded, close the valve. Check with your local oval track late model/sprint car supplier for the valve; they're commonly used in those environments.   vic

I could be wrong but, you're gonna need 2 valves aren't ya. One to isolate each master cylinder.

Hooking the rear brake to the front master cyl. seems much simpler. KISS theory

Just my 2c

you cant have 2 m/cyl in line... when 1 m/c pressurizes it bleeds out the compensating port of the other m/c... you cant put in a 1 way check valve cuz it wont release pressure
