Brake resevoir hose

[Stevehose]

I want to replace the original hoses from my reservoir to the master cylinder and want to keep the braided look, do I need special DOT 3 resistant hoses or will these work, and is the black hose the same as the blue one rubber-wise except for the cloth color, or do I need the blue version? They look the same. I prefer the stock looking black. TIA

Steve,

Although Continental makes both hoses, owns ATE, etc. The Blue hose is brake rated. Just like the a/c hoses, the formula and make up of hoses has changed over the years.

They do make a black cloth brake hose in their catalog, but I don't see it in your selection. maybe a little more searching and the black will show up.

steve,

just make sure that you choose a hose rated "brake use"

i can not tell which is the specification, for example i know that you need NBR rate type for fuel,

brake fluid is very particular, so make sure that you get the right material

i bought mine from walloth and it is blue rubber hose with blue cloth around

regards

The blue one is the original although they used to have a pronounced white thread in it but no longer.

I ordered this black cloth hose from penskeparts.com not too long ago for my master cylinder rebuild this spring: #21521163714 7.5 x 13(meter) for $9.12

Chris

this is supposed to be the original ?

 

[HB Chris]

Yes, blue is original except they used to have a white spiral thread around the hose. Today it is just blue with maybe white letters, made by Continental I think.

 

[Stevehose]

My brake hoses are original and they are black but am going to blue for a little more color under the hood.

Steve,

I hope you don't still have 40 year old hoses in your coupe!

Brake Hose Cutting

Has anyone come up with a way to keep the cloth from fraying? I know the tip about a piece of masking tape to get a clean cut.

DQ, the clamps look nice. I've seen tie wraps. Originally, I don't think there's anything b ut interference from the hose/ pipe.

Wax?

 

[HB Chris]

I believe they came with one clamp on the pipe but not on the reservoir end. Diagram 21/4 in RealOEM.

I do - replaced the rear brake hoses a couple months ago with SS - there was very little rear brake action, the fronts were changed about 10 years ago so SS going on there this weekend. The hoses from the reservoir to the MC and SC are original and also getting replaced, then everything bled. One (very corroded) clamp on the pipe to the SC, no other clamps - this will change. Also changing out the power brake vacuum hose and the power steering resevoir hose.

Steve,

I hope you don't still have 40 year old hoses in your coupe!

Thanks for this discussion. I will check all my hoses tomorrow. I wonder how many of us are driving with original hose. Is that possible, or would they have deteriorated by now

Doubtful! The original cloth braid will have frayed and disintegrated by now.

Be very careful with getting brake fluid on painted surfaces!

My '76 Si had the original hoses on it, still functional without leaks, but very stiff. You can see the "1-76" date code and the faint spiral white line running through it.

hi, when i work with black hoses, i use a piece of electric tape (the one from wurth that is made of cloth), and then i cut it with that garden scissors (those to cut flowers, you know), they make an astonishing clean cut, and the tape retains the cloth

i do not use conventional tape because with aging it spreads the glue out from it and everything gets sticky

in this case being blue hoses, i use the clamps close to the end of the hose to maintain the cloth inside them and nicely finished

DQ, the clamps look nice. I've seen tie wraps. Originally, I don't think there's anything b ut interference from the hose/ pipe.

yes, you are right, ther is no need of clamps or tie wraps, because there is no pressure over there, but as the fluid is not water, but the damned corrosive brake oil, i prefer to secure my steps, ha, ha

Wax?

hi luis,

good to see that you are working on it !

I can not see the lateral pipe coming out from your brake fluid reservoir, I mean the one that in my case goes to the clutch master cylinder (you can see how it is in my car in the pic i posted a couple of days ago)

explanation ?

 

[Luis A.]

DQ,

Good eye on the missing reservoir outlet. Automatic cars, having no hydraulic clutch, require only two pipes so there exist two different resevoir styles.

In regards to hose cutting. My favorite tool is the Sear/Craftsman Handi Cut. Scary sharp and strong blade:
