master cylinder

Hi all, Rebuilt my rear master cylinder and installed new Speigler lines front and back and speed bleeders al around. Bled the front with no problem at all. Have just been trying to bleed the rear for well over an hour. No luck and what seems like an endless supply of air. All connections are...

Cafe project needs MC out from under custom tank and owner doesn't want MC on the bars. Has anyone simply remounted the under-tank MC assembly to a new location under the triple tree? There's room, hoses/cables reach, any downside? Anyone have a pic of a bracket?

Thanks to Lee 98 I rehabbed my leaking master cylinder. I'll share a few photos but first a short narrative. Only issue I had was separating the master cylinder from the bike after removing all the screws necessary because it had stuck from crud and had to be tapped apart. The piston was in...

My front master cylinder on my F650GS Twin has a milky residue in the bottom of the bobble head. I know this happens when water binds to the old fluid. Is there a way to flush it out or am I going to need to rebuild my master cylinder... Thanks for any words CUJO

A friend and I were changing our brake fluid on our 2011 and 2013 r1200rt bikes. The bikes have 30,000 miles on them but this is the first time we've changed the fluid on these ourselves. My 2013 has always had more front brake lever travel than my friend's 2011. When we started to bleed the...

Both my riding buddies from the '60's want to relocate the under tank front brake master cylinder to the handlebars. A '75 R75/6 and the other an original owner '75 R60/6. I know the information is here on the Forum and have looked and "Searched" (useless) for it to bump start the procedure...

Went out to ride my /7...while backing it out, the front brake lever sinks all the way to the handle. :scratch Back into the garage. Background: rebuilt the front brake in early January with a new piston, square o-ring, seal, and pads. Bled the brakes...used DOT 3/4. I've been out on the...

I have most of the original tool kit for my '75 R90S with the exception of that forked feeler gauge for setting clearance of the piston rod at the back of the master cylinder. What is the thickness of that feeler gauge?

Ok, found a great tutorial. Now I just need to know where I can get s rebuild kit/parts to overhaul master cylinder. A new master cylinder is over $500��. So, would appreciate being pointed in the direction where I can get s kit. Cheers

I've recently acquired my first motorcycle -- a 1982 BMW R65. Today I decided to do some work on the brakes but have run into problems. I rode it twice the day after getting it back from the mechanic for a tune-up since the bike had been sitting for a long time. He assured me the bike was in...

Has anyone tried/used an aftermarket "universal" hydraulic brake or clutch master cylinder? Do the "universals" have the same hydraulic pressure output? Is that something I need to think about? Obviously, I have no idea how these are rated. The point being, my 2004 r1150r has the master...

Does anyone have any specific information on Converting from original Master Brake Cyl. (under tank) to one on handlebars? I only have a single disk system and do not need to go to 2 disks. I understand it can be done, but I would like an itemized listing of all parts necessary, including...

I just purchased a 2002 R1150RT (16,500 miles on it) and decided to address what I saw as the major issues right off the bat. I also wanted to reset the maintenance schedule as the previous owner wasn't volunteering much information. My issue arose after replacing the brake lines...

I'm doing a restoration on a 1980 R100T I bought on e-Bay. One of my projects was to move the brake master cylinder from under the gas tank to the handlebars(all BMW parts except for the brake lines). Today a friend and I filled and bled the brakes for the first time. I'm using Motul RBF 600...

Hello I'm new to the forum and I have a few questions for you experts. My first question for you is related to a dual-disk front brake system. I just brought my friends 78' R100S home today and have been tinkering with various things and noticed the front brake lever has no pressure. I took...
