I need to replace brake lines. The car is a 95 Sedan De Ville, with a 4.9 liter motor.

It looks like replacing all lines are not that bad except the lines going from the master cylinder to the ABS unit. I think they are 1/4 inch lines, so I was going to use 1/4 lines with bubble (ISO) flare ends. Well, I just noticed that each of these lines has one short section made of stainless steel braided flexible line.

Apparently I should not replace them with just simple steel brake lines. Those stainless steel braided part seems to be non-removable from the old line. There are no fitting or connector that allow this braided part to come off... Where can I find this line? I checked GMpartsdirect, Rockauto etc, but no luck. Are they dealer items?

Also, if anyone knows any tricks or whatever about brake line replacement, that would be greatly appreciated (especially flare nut sizes).

Thank you in advance for your help!

Curiosity killed the cat but satisfaction brought it back. Why are you doing this total brake line replacement? I'm sure you have your reasons. Just wondering.

When I replace brake lines, they are usually in good condition at the front of the car so I just cut them off and double flare them and bolt on new lines. My 92 Deville had metric brake lines but when I double flared it, it fit just fine on a 3/16 brake fitting. 10 year old brake line fittings are such a pain that I actually prefer to cut and flare them if there is some good line there to work with.

AMENCADDY,

Curiosity killed the cat. The rusted brake lines can kill you... They are getting so bad that I have to replace now before I get killed.

cadillac_al,

You are right, my case, the lines right by the fuel filter are very bad. Also area where the lines going from engine bay to the underbody is bad, too. But the lines going from the master cylinder to the ABS are also bad enough... Didn't you need to replace those lines between the master cylinder and the ABS?

That's a good reason :thumbsup:. never saw a rusted out brake line. Now I'll have to go check mine. I guess nothing is safe from the Big R.

Found items that I need.

Available at a dealer near by. They said each costs about $52.

I thought I was able to connect the master cylinder and the ABS unit with metal rigid tubes, but there must be a reason GM put those short flexible section in those tubes...

Brake lines can get pretty rusty before they need replacing. I never noticed they had ones with a flexible chunk to them.
