brake line questions..........

I have read several threads here on aging brake lines. There is no date code on my lines, that I can see. They are actually made by Toyoda Gosei. Just wondering if anyone has run into this.
The number on the lines is NO 9667.

 

I did find this on this forum....

I guess that answers my question, unless anyone has anything else to add.

 

When in doubt swap them out.
You will get better braking performance with stainless steel braided lines.
If you recently purchase this bike you can expect to spend $600 - 800 on updating fundamental safety and reliability items. Brakes front and rear being a big one in both categories.

 

the brake systems should be rebuilt every 4 to 5 years. Calipers, master cylinder, and brake lines.
pads and shoes.

TECH TOPIC: The Real Costs of Maintenance

 

Braided steel lines have a liner that is essentially good for the life of the motorcycle, so those won't need to be replaced. They are worth the extra up-front expense.

 

so if your in it for the long haul get the braided lines, They come in different colors
but if budgets have to be met then save the cash get the regular ones you will have time to save for the next time in 4-5 years.
color adds a nice accent blue fuel line and vac line, blue Braid brake lines, blue Grips ,blue lic plate bolts, helmet, gloves.....stop me please.................
what ever color you you like that is available

 

My brake lines on my 82 750 Maxim also say Toyoda Gosei 9667 with no date code and I was curious if they are original or if they were replaced at some point, possibly with factory parts? They certainly do not look bran new, but they also do not look like 33 year old rubber parts. I don't think my motorcycle has spent any significant time sitting outside in the sun, which may explain why the lines do not look that old.

I do plan on replacing them with new SS ones this winter when I do a full front brake system overhaul and front fork rebuild. I realize that they can look perfectly fine on the outside but be compromised and dangerous.

 

Derp. Mine say 9667 as well. Guessing they're going to need to be replaced?

 

When in doubt, replace.

 

Yes sir!

 

I know of no instance of anyone replacing brake lines with new rubber lines. If they are rubber they are most likely the originals.

 

if you can't read the date code anymore, they should be replaced !

 

The brake lines on my bike (1981) were date coded October 1980, so they were made when I was 6 months old. They didn't look like 36 year old brake lines or any 36 year old rubber part, I guess testament to quality.

They were replaced.

 

It's the insides that deteriorate first.
