This is a kit with two braided STAINLESS STEEL lines from the master cylinder under the tank to each of the line junctions on the fork legs above the brake calipers. It is for FRONT brakes only and fits these 1977 -ONLY Dual Disc models: R100RS & R100S - or any other model of that year which has been converted to dual discs. Replacement gasket washers are included with all brake lines. Bob’s braided stainless steel brake lines are hand crafted exclusively for us by a senior BMW Master Technician with whom we have a long standing partnership; and each one is made precisely to fit a specific BMW application -- the ONLY stainless brake lines available which can make that claim! You're assured of the highest quality and correct fit for your bike. The brake lines shown here on our e-Store are the most popular standard applications. But there are many more! If you don’t see the line you need, or if you are in search of something custom made for a specific application, please CALL! Why switch to stainless? Stock lines on most BMWs before 2004 are made of reinforced synthetic rubber which, even when new, expands under pressure, leading to a mushy feel. In older marginal systems this can lead to the brake lever running out of movement before full system pressure has been reached. Our brake lines consist of an extruded Teflon hose, tightly wrapped in stainless steel wire braid, then coated in clear plastic to protect painted surfaces. There is virtually no expansion and you get better braking performance!
