Datsun 620 Brake Lines

[DATSTON]

How's it going gents.  I was wondering if anyone had the lengths of the brake lines.  I'm having a local datsun shop make some steel braided lines for me, but they need the lengths.  I'm currently at work and they need the lengths by today in order to have them ready for me by saturday.  if not then no worries, ill measure them over this weekend and have them made and pick them up next weekend instead.  was really hoping i could replace the brake lines this weekend so i can start taking the datsun to work on the weekdays.

 

thanks

Stay with hardlines.

Stay with hardlines.

not questioning you on this suggestion, but is there a reason to this?  i always though steel braided brake lines were more durable and holds pressure longer.  the old brake lines on the 620 is barely holding pressure.  im pushing the pedals through the floor just to stop.

so i wasnt able to find some prefabbed steel braided brake lines made for the 620.  but i did find these online.

 

i would need 2 for the front

and 1 of these for the rear

can anyone confirm?  are these lines any good?  i still want to go with steel braided lines, but if regular brake lines are suggested, then i might go with these instead since its already made to fit the 620.

i was able to get the rear brake line information through JC Whiteney.  I'll post the specs here in case anyone else in the future needs it.

Have you looked at Rockauto for the lines you need?

i haven't yet.  i have only checked on summitracing, jcwhitney, and datsun parts llc so far.  ill have a look at rock auto right now, thanks.

[DATSTON]

rockauto pretty much has the same parts as JC Whitney.  similar prices as well.

 

ill just repalce my current lines with regular brake lines for now.  ill look into getting steel braided lines later once i have everything out and measured.  thanks for all the help so far guys.

[DATSTON]

Rick Rat, rockauto turned out to be almost $30 cheaper for everything.  thanks for the suggestion man, i owe you one.

Hard lines will last longer...MUCH longer.If youare losing pressure and you see nothing wet,then the lines are NOT your issue.Last but not least(maybe),no line you have made will be DOT approved.Long lengths of braided line would make me nervous.

makes sense.  i just bought OEM replacement hoses.  i will be refilling the brake fluid and rebleeding the brakes.  lets see if it fixes the issue.

If you see no wet spots,then something is leaking internally-MC,caliper,wheel cylinder.

ill have a look over this weekend to see if anything is leaking.  previous owner told me the datsun had its MC replaced less than a year ago.  ill have a look to make sure.

saw this on ebay and it kind of threw me off.  according to datsun LLC when i called them, i was only suppose to have 2 brake lines up front and 1 down the center in the rear right?

this ebay post is selling a set of 4 hoses.  should i have ordered 4?

[datsunaholic]

There are only 3.  Well, there are 4 hydraulic hoses but one is for the clutch.

[Z-train]

Back the bus up-are you talking about the lines that run the length of the truck on the frame or the rubber ones to the rearend housing & the calipers?

[datsunaholic]

Pretty sure he's talking about the HOSES. 

 

I can see the confusion, since the brake LINES are the steel flared pipes.

hard lines last longer and DONT flex. SS lines still flex, just not as much as regular hoses.

if the braids arent coated and they move, they will cause abrasion to paint and any other parts they touch.

SS lines become 'work hardened' and are harder to work with.

hard lines can be bought at any auto parts store for pretty inexpensive
