Hi,
Hoping the power of the forum can help me.

I have a 96 ABS2 K1100. Last summer I noticed a small leak from the front brake lever area. Following the advice it seemed to be a piston problem at the bottom of the reservoir. I purchased a master cylinder repair kit, but the leak has returned within 500 miles and now the brake lever pin is solid so cannot take that apart.
Is my next option a replacement master cylinder. If so, any advice on a good place to buy second hand (UK or Europe).

Thanks

Andy

But probably not if you were in UK or Europe...

Andy - I have a 97K. Had the front master rebuilt twice - ended up getting a new one.

Problem now is that BMW sued Magura, the company that makes the master cylinders, because Magura was selling to re-sellers. BMW put a halt to that, which means you now have to pay the much, much higher dealer price - unless you can find a re-seller that has still has some on the shelf.

If I had seen this suit coming in time, I would have bought another new one to have on hand. On the other hand, the original lasted about 15, 16 years...

If you plan to keep the bike, a used master cylinder is probably going to be as problematic as yours.

My .02 - bite the bullet and buy a new one...

Thanks all.
The advice is appreciated.
I had looked at second hand and new - the price differential is not massive so probably going to go new.

No complaints, I reckon the one on there is the original.

Use red grease when installing and refresh grease every few years.
Red grease as in designed for brake seals.

So, no new stock available from Sherlocks so gone for reconditioned unit - 6 month guarantee. Unit is also resprayed so cosmetically good too.

Thanks to all those who posted advice and tips - the power of a good forum.

I had my bike service as the weekend and when I got it back I had a big smile as rode home. 19 years old and still a great ride. I had test ridden a brand new R1200RS earlier the same day and I got just as much pleasure from the K.

Confirms my plans to always have in the garage
