Need Front brake master cylinder.

[Flyinfool]

Looking for a good front master cylinder.

I put on a delink kit and was unable to get a good lever action. I can easily pull the lever till it contacts the grip and only have a fairly good front brake action The front brake was better when I was only using one side. I have used every bleading trick ever written in this website and even some that were never written, but it still is not right.

 

I took my master apart to do a rebuild and the bore is very pitted.

So rather than spend $25 on a 14mm hone to try to clean it up (some of the pits are pretty deep) which still may not work.

I am looking for a good front master to buy.

 

I know there are a few people parting out bikes.

 

I am also watching a couple on flea bay. But I hate to buy one from a stranger on ebay, pay the shipping, and find out the bore is just as bad as what I have.

 

I STILL HAVE LAST YEARS GAS IN THE BIKE!!!

I'm pretty sure I have one around here somewhere. I'll see if I can dig it up. If so you can have it for shipping.. I am hoping to go to Bob's later in the week so I can ship it from his place (States Side) to save a few $$$

Cool, Keep me informed and let me know how much to send you.

Since you delinked the brakes, it would be helpful if you put a 9/16" master on at this time. That will give you more volume to drive the doubled caliper piston volume.

 

MKII's had 9/16" brake master's. MKI's were 1/2".

Wayne,

 

There is "14" cast into master reservoir near banjo bolt port on the 9/16" units. 14mm roughly equals 9/16" (.5511")

 

1/2" masters had "1/2" cast on them. Don't know why fractions once & metric on later unit.

My bike is an 88 and does have the 14mm master.

 

With all of the pitting inside it might be closer to 15mm in places now.

Mine's an 89 and has "14" stamped on the Master...

Well I got my new master installed and bled out, and now have front brakes again.

Thank you everyone.
