C20 Rear Brake Hose Solution - The 1947 - Present Chevrolet & GMC Truck Message Board Network

PepperTreeGarage · 01-24-2019, 11:04 PM

This was my solution to the C20 Rear Brake Hose dilemma. This all started when I got the wrong part from NAPA. They didn't have the correct hose for my '72 C20. The NAPA part number is 36765. They have this hose as fitting 1974-1986 C10s and C20s. Now this hose by itself doesn't quite work, but with adapters it does. I found that adapters are available when I went to the Hose-Man to have a rear brake hose made up out of braided line. It did cost a bit more than going with the NAPA hose. The NAPA hose with the adapters would cost approx. $30.00 total. This solution works for the C20's that have the distribution block as part of the brake hose. First pic is the stock hose. 2nd and 3rd pic is the NAPA hose. The 4th pic are the 3/8-24 to 7/16-24 adapters. Last pic is the new hose assembly on the DANA 60.

Here is the hose I used. No adapters necessary. NAPA 36683. And it looks as if your hose is pointing out the back of the axle instead of forward.

Yes, it's pointing towards the rear of the truck. It's a '72 C20 with the DANA 60. The Stock hose is 15 inches long. I looked up the NAPA 36683 hose and it is 20 inches long. Which would work nicely if my truck wasn't lowered. So I opted to have one made to the 15 inch length. The NAPA 36765 hose is 14.8 inches long, so it's closer to the stock length. Thanks for posting the hose part number that you used, as I'm sure it'll help out the next guy, which is the purpose of my original post.

Well I suppose I got lucky. The local NAPA here in Santa Clarita is an independent and the counter guy spent the time to sort through to match as close as possible to what I had. They had the longer one but also had a 38520 which is 18.625" and yes when I lower my C20 CS it will need to be tied up so I will install a loom on the underside of the bed to take up the extra 3".

Now I see what mine will look like...well sort of. Yours is lower.
Looks great! Although your bike is missing some parts mine has (plus my bike weighs just a tad more) LOL!

What are the details on your lowered c20?? It has the exact stance I'm looking for on my 71. And I saw that yours was leaf with a Dana 60.
