question about braided brake lines

[Downeaster]

Usually, yes. The two times I tried to use a Mike's MC kit, I wound up cleaning up the original piston, cup and spring and popping them back in.

Don't use anything but fresh brake fluid to clean things with, wear nitrile gloves (or whatever you prefer) and DO NOT get brake fluid on paint. It makes a great stripper...

You may need new piston seals on the caliper, but other than that a good cleaning and inspection works about 95% of the time in my experience.

So can I use brake clean to clean things up?

Only metal, NOT rubber parts

 

[bluesman650]

OK thanks. My snap ring pliers don't reach the snap ring on the MC. Does anyone know a source of the long reach pliers other than Mike's?

 

[gggGary]

I just buy a long nose micro needle nose and lightly grind the ends to fit the snap ring. It really helps to go in with an awl and get the snap ring freed up by probing, twisting it in the slot before trying to remove it.

Thanks Gary, I think I have a pair of those. I also might try using a pair of picks.

K&L makes a nice pair but they're not cheap .....

Thanks, it came out pretty easy using a straight pick and a offset one,

Depending on what MC you are using you need to pay attention to the orientation of the banjo fittings. That is why I like the ones Mike's sells because you can orientate the ends whichever way works best.

This is true, but you have also added 2 more spots on the line for potential leaks. FWIW.

I got my braided lines from here http://www.apexbrakes.com/custom.asp . Very reasonable prices, ship fast, and you can get any length you need up to 60"

HI, Do you remember what banjo bolt angle and what female end you ordered? The reason I ask is the only angle I see for the banjo is for 45 deg. and the ones Mike's sells say's it has a 20 deg angle. How important is the angle? The one at the MC on my rider is straight but the one on the parts bike is angled.
Thanks

What I got wouldn't help. I've got radial master cylinders, so for stock I couldn't say.

OK, Thanks

Parts manual Diagram.............45 Degree......Don't think so, 20 degree angle is for a reason

Kinda a conglomeration by Yamaha but if things are done properly there should never be leaks, and if you do find someone to make up 2 lines that eliminate the 2 steel brake lines then there are less joins to do so it will eliminate 2 joins.

Bike Bandit has a nice selection of fittings:

Goodridge Banjo Bolt

The angle on the MC banjo simply helps direct the hose properly. It's more important with stock or maybe higher bars. I have lower, narrower bars (Euro bend) and a straight fitting works just fine .....

 

[racerdave]

A 20 angle will help clear the caliper

 

[mrtwowheel]

I think the hose that I got from banggood described the angle as 45*, in reality the angle was much less than that.

Yes, down at the caliper, you want/need a slight angle, on banjo bolt types that is. His caliper is the threaded fitting type. I think they only come straight. That's why I would leave the factory steel pipe down there and just attach the new line to it.

 

[bluesman650]

OK, I want to leave both of the stock steel pipe and just replace the rubber hoses with braided lines. Or am I just wasting money for what I'll gain?

 

[5twins]

No, the original rubber lines need to be replaced. Stainless lines are the way to go. They pretty much never "wear out" and go soft like the rubber ones do, so this should be a one-time replacement deal. When the rubber lines go soft, the lever feel will be mushy and no amount of bleeding will fix it. The new stainless lines should restore the hard lever feel.

I'm surprised no one around here has ever reported the fitting size and type used on these lines. If you knew that, it would be easy to search out replacements or have custom ones made. I would imagine it is a metric thread.
