Why the railway line is not a straight line but full os bends

Here's one reason: Railroad tracks are made of steel which expands and contracts with temperature variation. If long straight sections of track don't have expansion joints in them (which they usually don't due to the continuous ribbon rails they use today) then expansion or contraction needs to be taken up by the nearest curve. Otherwise the track can experience "heat kinks" where the rails buckle upward. Very long straight sections are a problem in this regard so adding curves alleviates it. One other reason is that rail lines follow contours that offer very shallow grades. Trains don't do well on hills.

1999 ford escort SE rear brake line leak

You can replace line in full section or just a piece. Full section would be my suggestion, remove brake line from end to end that is bad..this doesent mean you have to remove the complete line clear up to the front of car,it should be in sections. After removing bad section take it to auto parts store and as the can give you the correct size without guessing. Most sections bought at auto stores are straight and can be bent useing brake line bender.They useually cost around 15 to 20 dollars.....after bending and replacing be sure to bleed brake system.....nedd more help fill free to contact me...good luck

The brake line i bought for my 1999 dodge caravan doesnt fit or the flare nuts are the wrong size what size do i need

If this is a formed metal line or a rubber brake line the best solution is to take the line to the auto parts store so they can match it up. I can't tell you how many times I had to go behind the counter to look at what they had in stock. If this is a metal line the auto parts store has lengths of straight line get a quality tubing bender to make the bends in the line. You will be an expert after you make the first couple of bends. Hope this helps

Tansmission line broken

U will need to make a new one from straight stock tubing, u will need to remove yours and use it as a template to bend a new line to fit, u will need a good quality tubing bending tool and a tubing flare maker tool kit.

I am looking for the rear brake line for 99 gr caravan it has about 7 bends in it and i cant seem to find part number or anything about it

You obtain the line straight and have to make the bends while installing. measure the lengths of the old line and get a length that closely matches. NAPA should have your line without costly dealer part.
