R65LS Front Brakes

[wmsoller]

On the R65LS, there is a distribution body behind the headlight at which point the brake lines split into two for the twin brembos. Does that distribution body mount on the front or back side of the panel where the headlight mounts? I'm doing a project and wasn't certain how it should sit in there or how the line is situated between the distribution point and the master cylinder? I thought someone may be able to send me a few pics, which would be appreciated. I'm at wmsoller@yahoo.com

Thanks much for any help.

Without going out to the garage to look at mine, I believe the headlight mount sits too close to the steering head to mount it there. It seems like the only place that works is in front towards the headlight.

Will look in my collection of pics - getting that plastic inner side cover off is getting to be trickier as it ages.

Not an LS and not sure if the equipment is different but here's a couple of pics of my non-LS assembly.  Back of the headlight plate is where I remember the dual hydraulic line splitter being attached. Sorry for the big photo.

Mikes pic shows the line from the m/c connecting to the wrong side of the splitter for some reason. Also connecting with a steel brake tube, the standard rubber hose on my R65LS connected directly to the splitter as does my SS brake hoses.

I've been down to the garage and had a look, it's easy to see from below those pesky plastic infills.

The splitter fits to the back of the bracket and faces the steering head and the m/c hose loops down and back up to the m/c. Hope this helps.

The splitter is the same part on all R65's it just has 2 blanking bolts on the single disk model.
The extra blanking bolt on the dual disk bikes was for an old style brake light switch.

Maybe different fitment than your bike Bruce?  Seems to be right to me and exactly as assembled from the factory.  If something is truly wrong I would like to know what the corrections to be.

Hmmm...sounds like two different options. I think the bracket on Mike's must be only for the non-LS. Bruce's description sounds like what I thought it would be for the LS. I looked on Max's fiche and it's not clear which hose. It also presents two options, of with both appear no longer available. I suppose one could improvise...Thanks all for your descriptions and pics.

The pictures that Mike shows, is a setup for the dual disc '81 R65 .

Same as my '81, don't know if it's the same on the later bikes with one disc .

Some owners of single disc bikes, have removed the splitter and use one brake line from the master cylinder to the caliper .

Another version for dual disc that I've seen pictures of in a dual disc bike, is using one line from the master cylinder to the caliper, then using another line from one caliper to the other .

Can't remember how the line from one caliper to the other was secured .

What does the set up look like on your two LS models, Bob? Thanks. Will

There's one line from the master cylinder to the splitter .

At the splitter end, there is a 'banjo' fitting with a hollow bolt, then two lines out of the splitter to the calipers .

I'll have take a look at the line when I get home, but I think the master cylinder end of the line also had a 'banjo' fitting .

On my LS, it has the splitter mounted on the front of the steering head tube like yours is in the picture.   However, the line from the master cylinder connects up on the right hand side (same side that the M/C is on) and doesn't cross over to the opposite side.  

Like Bob R indicates, mine also has the single brake line (which has banjo fittings) that goes straight from the M/C housing to the splitter.  It does not connect to an intermediate steel pipe like your photos above show.    When I converted from tall, USA handlebars to the short, Euro style bars, I had to replace that line with a shorter one (ordered through BMW dealer) as it would otherwise have had a seriously kinked 3-4" loop trying to fit behind the headlight - wasn't going to happen..

On my 1982 R65LS, the distribution piece is bolted behind the panel - the side closer to the tank.

On both my 82LS and 84LS the splitter is mounted to the backside of the headlight mount plate, between the mount plate and the headtube. A short brake hose from the master cylinder goes into the nearest connection on the splitter with two hoses out the bottom, one to each caliper. The opening on the far side of the splitter (away from the mc) has a plug in it.

Here are a couple of pictures from my restoration of 1982LS.
