R100 GS Front Brake
Hi All

My front brake on my GS is useless, it's been cleaned etc and had new pads but after having a break from the bike and riding my road bike. I forgot how bad it was.

Any one got any suggestions, brembo 4 pot caliper have been recommended and change the discs.

Cast Iron discs are much better than stainless steel - you could also try a goodridge brake line - I believe it's possible to have a twin disc conversion too - but this will probably require a change of forks - and from what I've heard it's not all that much better than the 4-pot option.

Forget the twin disks - way too heavy and expensive for the improvement.

I went for a 320mm disk from M.A.P. Engineering - although I'm sure ther are others available in the UK more easily that will work.

Cast Iron is good, but a pain - and ugly - for street / off-road use. A good high carbon stainless disk is fine.

Then I put a Performance Machine 6 piston caliper on it - a huge difference - even from my PM 4 pot caliper that was on it before, which was a big improvement over stock.

Add a braided stainless line, and you'll be most impressed, I guarantee it.

See the story on my bike for pics of the new brake.

Hi guys

Will have a look into the options, already have a braided hose on it so one less job to do.

hi julio
motorworks do a ready made conversion using a k1100 caliper which works a treat

cheers chris
