Hooking up sidecar brake on Tonti
« on: November 27, 2022, 11:23:57 AM »
hello Folks, I will shortly be hooking up a DMC M-72 sidecar on my 98 V 11 EV. The DMC has a Brembo disc brake on the sidecar wheel,and a long brake line with a banjo type fitting on the bike end. My question, is with the Guzzis linked brake system what is the best way to go about this, as in where to tap into the brake system for the sidecar brake?  Would it be better to de link the linked system, or leave it as is? Im sure with as many sidecars that have been added to EV's, other have dealt with this before.
any tips, and suggestions from the group, much appreciated.

I would think you need a larger master cylinder . Sorry but i don't have more than that.

I read a sidecar book from the 1920ís that suggested having the sidecar brake separate from the mc brake. They said that the sidecar brake did not add a great deal of braking to the total braking performance. It was much more useful if it could be used by itself. So thatís what I did on my Bassa. I used the top clamp cut off of a bar riser and mounted a stub on the handle bar with a lever clamped to it. The lever is above the clutch lever. From the lever I ran a cable to a master cylinder on the sidecar frame. I used a  master, rear wheel and brake from a T3. It didnít take long to get used to it and it is wonderful for maneuvering. Right turns are great after some practice. On the highway if I want to ease a little to the right I just brake the car wheel and the whole rig just easily moves right while staying straight. The only drawback is itís harder on the car tire if I am too aggressive having fun with it for it will skid if you unload the car wheel with too much brake applied . Iíll post a pic later. I did de link the mc brakes later on but it wasnít necessary

Hook it up to your hand brake.  Longer banjo fitting or another m/c on either left or right handle bar.

Pics not so good but ok, you get the idea. It does work well and I miss it on other rigs. Itís more suited for sporting

Thanks guys for the suggestions. Thats a neat way to hook it up, John. I like the idea of using the sidecar brake as a turning aid. I would have never thought of hooking things up that way....Brilliant!! :thumb:

There's a guy out here that has his clutch and front brake on the left handlebar.  Nice set-up.  He lost use of his right arm from an accident.

You have the brake so I am sure that you would like it to operate but  I have not found the need for a sidecar brake in the last 35,000 miles,  just 1 more thing to get accustomed to in my opinion.

I think I may be able to hook it up on the top of the rear master cylinder. There is a banjo there, and I think there may be enough room to stack the one from the sidecar there.
