Brake and Fuel lines

Post by keng on Wed Dec 19, 2012 1:31 pm

Well it's that time of the year when my R1100 migrates to my workshop. Being 15 years old I think it's time to rebuild brake parts and lines plus replace the fuel lines. Has anyone done this to have any words of wisdom? For example do I need a caliber kit with the pistons or just the seals, can I use normal 5/16 " fuel lines, etc?

I replaced the fuel lines on my R1100RS a few years back. Used BMW hoses. The fuel pump is a bit tricky to get out and back in, just take your time and be patient.

Suggest you replace brake lines with steel braided.

Galfer brake pads are popular Maybe Hemshaw can chime in with benefits of using the Galfer brand. Smile

Don't need pads, they should be ok. My calibers are sticking though, so need to replace seals and clean the insides. Will also replace the lines.

I've replaced the fuel filter before so know about the art of removing the tank guts:-) General advice seems to be to use BMW hoses since universal ones don't have the required bended shapes and cause grief.

For the brake lines, is there any advantage to the steel lines? I won't be racing:-) Maybe I should just replace with OEM rubber ones, since the originals still seem fine.

Rubber lines expand and diminish the breaking power. Having a steel braided line is almost equivalent to having a steel pipe between the master cylinder and the caliper. The full power of the MC is transferred to the piston(s) in the caliper

Most of the times, you don't need to purchase a rebuildr kit. A good cleaning and the addition of petroleum based lubricant (vaseline) on the piston seal will solve most of the problems.
A rebuild kit is only needed when you get a leak.

What #DOT fluid do you use? You have to replace with the same viscosity. Otherwise you may end up with gel...

Steel braided lines are probably cheaper than BMW replacements. You won't be sorry if you go steel braided, much better "feel" and control.

Thanks guys. I checked with 2 local dealers yesterday and neither can supply pre-fitted steel lines for my bike, so will go on-line. Speigler has a kit and probably others. Any experience here or are they all about the same?

I bought Speigler but other brands are probably just as good.

Just checked in.... from Cancun. Very Happy
Merry Xmas to all.!

Ken, I got good deals at denniskirk.com for lines. It was Goodridge brand.
I bought easy fittings to screw on that are reusable for longer/shorter lines.

Today I ordered Spiegler lines from Blue Streak Racing in Toronto. $199 with free shipping, no duty and a really nice guy to talk with. No extra charge for color either:-) Now I wait!
