Brake line question

Post by primekutzz » 20 Aug 2009 08:29

I'm gonna be doing a complete suspension and brake upgrade in a few months. I've sourced most of my suspension and brake parts from Ermish. However, for the braking system, the master cylinder is coming from Ebay. I don't have any brake lines on the car as it was a shell and never came with them. So I'm blessed with the task of bending up and fabbing up my own brake lines.

Question is: Anyone here done this before on the car? How hard was it? What tools do I need (bender and flare tool)? I have a few diagrams of a stock 510's brake lines, should I follow that general routing of the lines or should I see if I can improve on the layout? The car is currently undergoing a sr20de swap (non-turbo), should I make any special provisions or routing for the brake lines? Lastly, there are a few kits online, but does anyone know which one i should go with. I know Eastwood has 2, and total cost involved has a universal SS and regular steel kit. I don't know which one i should go with and what size tubing to use.

Anyone out there that can help?

I bent all the brake lines on my car. You need a pipe bender and a flaring tool. It helps having a friend there with you too. Doesn't the one stock brake line go to the rear brakes go up through the tranny tunnel? I re did that one, and just ran it back the same route as my fuel lines. I wouldn't buy any kits, it's too easy to do yourself man!! Get some 1/4" line, a tube bender,some fittings, and a flaring tool and go to town!

I did my own lines on my SR swap, all of them, the only one I reused was the one that goes to the rear, but I re-routed it similar to my fuel likes also. Here are some lessons I learned:
1. Get a good flaring tool, or find a shop that has one and have them flare your lines after you have them all bent up. This is probably the most important step. Those cheap flaring tools at your local parts store are just that, CHEAP. I wasted a ton of money on lines trying to flare them with one of those cheesy tools. It is very difficult to get a good double flare with these type tools. If you want to buy a good one it's gonna cost you about 320.00 for the nice hydraulic one they sell on ebay. Trust me here, it's worth the money, perfect flares every time.
2. Get a decent bender, doesn't have to be expensive, most any one will work.....they look like a pair of pliers with different sized dies that change out to accommodate different sized lines.
3. Do not over-bend the lines, it makes them weak and it's not good....remember your brakes stop you.....the single most important part on a moving car period.....a million HP ain't gonna help you in this department.
4. I bought the lines they sell at your local parts store, they have pre-made lines, in different lengths, with the fittings installed, get the closest one and cut one end to length, then you only have to flare one end.
5. I ran across two different color lines, one had a green type coating and the other was just the silver color, either will be good....I really don't know the difference?? There are also stainless steel lines, I think this is overkill.....I mean really, how many cars come from the factory with stainless lines???
6. For the line that runs from the proportion valve to the right side, I ran mine across the back side of the engine crossmember and used two ADEL clamps attaching it to the member. Gives a cleaner look.

...almost forgot, I used a piece of string to determine how long each line needed to be, then took all my strings to the parts store to make sure I got the lines long enough for each one.......

Hope this helps....Rich

If you haven't bought your line yet, consider this stuff.

http://www.fedhillusa.com/

It's the best stuff available, copper nickel alloy. Extremely easy to bend, I used my fingers for all but the trickiest sections, and totally corrosion resistant! It was a joy to work with, and I've done lots of work with the steel lines in the past, never again.

Also, use 3/16 for brake lines, and 1/4" for the clutch lines.

Wow...thanks for all the great input. I'm guessing 3/16" line is what I need. What size fittings do I need to get to make them fit a stock master cylinder and would it be overkill or unnecessary to get an adjustable proportioning valve like this one from Summit Racing...http://www.summitracing.com/parts/SSB-A0730PL/

This is another reason I bought the pre-made lines, it comes with the fittings, you will need the standard metric with standard double flare. just take one of the short lines with you to the parts store, you can be sure to match the thread pitch and ensure you get the right ones. As for the adjustable valve, it's always good to be able to adjust something, especially if you put disc brakes on the rear, but i used the stock stuff and mine stops fine.....is it perfect, I have no idea, but I am not a racer.....or a maniac driver.

i used a mate of mine who is a brake guy to do all new lines on the car when the shell was ready, now im in the middle of a small acco repair which has turned into another full respray, and this time im ditching the small factory splitter and valve that came with the 240k booster and master cylinder that i run on the car with a wilwood adjustable valve,

sorry to tread jack, but you know the 240k is worth big bucks in Japan, very rare here, there are many KenMary cars but the Aussie 240k is money here in Japan.
