I have a 1995 GL1500 Aspencade with a Motortrike trike kit. As a disabled rider I am trying to combine most (if not all) of the brakes to the hand lever. Originally the hand lever only worked the right front disc brake. Last winter I had my mechanic route a new brake line to work the two drum brakes on the trike. He felt the hand lever master cylinder would support either the two front disc brakes or the two drum brakes in the back. I didn't think I would want both fronts only in an emergency situation, so opted to have the two rear drum brakes. I now find that the stopping power of only the rear drum brakes is not adequate. Not even as good as the original right front disc, so I need to add at least one front disc brake to the equation.
I have already tried to use a double banjo bolt with:
1) the new rear brake line to work the two drum brakes along with the original line to the right front disc brake.
Result: brakes were Very soft and in a simulated emergency situation the lever went back to the throttle as the front master cylinder could not push enough fluid...
2) rebuilt the front master cylinder
Result: no change...
3) bought a new OEM brake line to work the right front disc brake.
Result: no change...
4) placed a 10 psi residual valve at the front of the metal line going to the two drum brakes.
Result: no change...
So, right now I am back to just using the two drum brakes on the trike and down shifting a lot.
Has anyone accomplished this type of brake setup?
Is the Front master cylinder from a GL1800 bigger than the GL1500?
Does Honda make a bigger front master cylinder that will work?
I read somewhere that possibly one of the trike kit companys can bore out the front master cylinder and use the piston from the Valkyrie.
What about using a slave cylinder to actuate the Rear master cylinder, since it is already setup for the 2 rear and the left front brakes?
Any help would be most appreciated... Ron
