I had three bikes with linked brakes. RT linked front to rear, rear not linked to front. LT linked front and rear also had servo brakes. Honda ST1300, front to rear, mechanical system with another master cylinder mounted to the caliper. All worked well but also had anti-dive front suspension and ABS. Unless you know you can get the proportioning correct I wouldn't bother.

had em on a bmw r1150rt.
they were linked,abs and electrical power assist.
yes they were amazing.
but...
very very complicated with a bunch of solenoids and bleeders.
when the key was off it was just like a car with engine off,amost NO brakes.
you would have to grab with a death grip with very very little braking, then if they decided to come back on look out !!
i sold it because i believe brakes mean life or death on a bike and i did not trust them.
the price of new brake modulator was around $2000

I had the LBS on my Honda CBR1100. Loved them! Now if you're tracking the bike I agree you want independent control. But, for daily riding and panic stops LBS are fantastic!
Very complicated to bleed, and in your case, install I imagine.

I drilled so that the middle piston worked. Couldn't locate a non linked caliper.

I need to do more research on how honda links their brakes on the VFR...I'm pretty certain it isn't as complex as the BMW system you note. Especially the electric assist. Why would you need power brakes on a motorcycle? Isn't 2 finger braking enough?

My take on the bonneville line is that these are wonderful, simple to work on machines that keep the rider squarely planted in the direct experience of riding. There's no wind protection and no ABS or other electronic interventions - other than a rev limiter. That being said, I'm willing to buy the bits/plumb this up as necessary to get these linked up, but won't bother if the benefit doesn't outweigh the added complexity.

Thanks to all for their input.

Cheers,

--Rich

they were more like 1 finger....
with the key off though and just pushing the bike around by hand to park it or move around the garage they were pretty useless. if you blew a fuse or had an electrical fault someplace in the system you were screwed !! if i remember correctely the manual stated every 2 yrs complete fluid change. that was one heck of a complicated procedure with factory tools.

I may be oversimplifying this, but seems to me a double banjo at the rear m/c and a brakeline up to the front caliper should do it. It's not like you'd ever mash down hard on the rear brake anyway, and one pot pressing one side of the front wouldn't provide extensive braking under any circumstance. I'm just thinking with them linked, trail braking with the rear brake in a turn would be more effective and keep the bike more in trim (front to back balance). Just my $0.02.

Had 'em on my Blackbird and basically forgot they were there after a while. My 2 cents, I would NOT invest a lot of time and expense to make linked brakes work on a Thruxton.
