master cylinder

Hello, The last of the known faults is the front brake. I thought I might as well try it with some fresh brake fluid. Nothing dooin. No fluid getting thru. Decided to take it apart and check the seals. Its stood for years and the MC had been all clogged up. It came apart quite easily...

Brake Dudes, I believe I have it sorted out (new kit on bottom in pic, old parts on top - obviously!). Only question is, no brass disc in old parts and only place I see it going is between the rubber spring stopper and the metal piston (for what reason I don't know other than perhaps more...

My original M/C has a piston 65mm long. All sites seem to say the refit kit piston at 53mm will work. How can this be and what will the 12 mm less mean to performance? Any ideas? Its a 75 650xsB Getting real excited about firing it up but need a solid front end. Shipper

Hey folks. I'm In Vancouver BC and need some welding done. Hey there. Anyone in Vancouver BC willing to do some welding for some dough re me? I need mounts for my rear master cylinder. Really close to being done my first build, and itching to get it on the road! Thanks for yer time...

Hi guys So I'm up to getting my front brakes dialled in, and need to find myself a master cylinder. Can someone please help me out with identifying what type and size brakes these are and advise me what size Master Cyl they are running if they have the same brakes? My bikes a bit of a swap...

Can I make this Master cylinder/brake lever fit on my 1980 xs with the stock caliper? It has a remote reservoir so I can replace it with the right size.

Sorry if this is somewhere's on the site. So, the 1981 SH model, has the multi-part brake line to the front brake. What I'm wondering is...was the break up of the line done for aesthetics to keep the line from getting all wild? If I was to remove item #12, the joint, and just run...

little bit of background. Just rebuild the bike, new lines, no fluid in anything. This is the master cylinder I have: http://www.mikesxs.net/product/08-0255.html I have been trying to bleed these brakes for 2 days now, today I spent 2 hours trying to get them to bleed. (first using the...

I'm running apes on my bobber build and the stock MC is just too bulky... Any suggestions for what front master cylinder I should look for to run? Experiences? Any help is appreciated.

This will cover the procedure for rebuilding the front brake master cylinder (m/c). All 3 types will be covered. There are 3 stock types of front brake master cylinders on the XS650. The original Round Cover: insert round assembled here The "Standard", which has no angle, straight body...

Bike: 79 XS650, single front disk brake. All stock. So today I finally decided to stop putting it off and flush my front brakes (owned the bike for 3 years now). No surprise the fluid looks like red deck stain. Once I got most of the old fluid out of the bleed screw I added some fresh DOT3...

In a previous post I metioned the poor braking on my bike. I have a resurfaced and cross drilled single rotor. It takes a healthy squeeze to stop. I'm running a GSXR rear master cylinder with stock rotor/caliper and it seems to take a lot of force as well. In previously owned XS650's I...

Tell me about rebuild kits for the XS650B master cylinder. In the M/C for my '75 XS650B, I can move the plunger with compressed air and I can squirt brake cleaner through it. The plunger doesn't return on it's on, though. I see in the diagrams there's a spring in there....maybe my spring...

Hi Everyone I am new here I have 2 xs650 78 &79 The question is, is there a left side caliper that will fit as the mag wheel is drilled and taped for a rotor on both sides and the fork tube (left) has mounting lugs.

Was wondering why a front master cyl, that has sat for a long time off the bike, would be "stuck" such that I can't get the lever to push in and out etc. Its like once the little brake light switch touches, it won't go any farther after that. I have 3 different ones I could use and wouldn't...

Anybody using one? If so: Of the 2 "bellcrank" ones he sells, why did you choose one over the other? one seems to have a square shaped reservoir and the other a round one. Trying to figure out the difference between the 2 units, besides that one is black and one is silver, and shape of...

Hello, I found this forum through Facebook. Some of you may know me from other sites on the web... I hang a lot at the Sportster forum (www.xlforum.net) - lots of good folks there and some of them are even into XS's. Also the XS650 "list" the Micapeak list. I've been on that a long...

Hi guys, tryin to find some type of cable operated remote master cylinder I can use on my build so that I can run these inverted levers with internal cables. Any suggestions? Thanks
