Cadillac Seville / Cadillac Eldorado Forum Discussion, Replacing Brake Line in Past Cadillac Vehicle Discussion; I have to replace a piece of brake line. This line feeds the left rear. One end of the line ...
I have to replace a piece of brake line. This line feeds the left rear. One end of the line bolts into the proportioner valve and the other end to the brake hose leadind to the caliper. The piece that came off (cracked and leaking brake fluid) is a U shaped piece. Went to local supplier and they sold me a straight piece. So the question, how can I bend this piece of pipe to the required U shape without compromising the passageway within. I have only the basic hand tools.
most parts store brake line can be bent by hand, the tool does help though, if its alluminum color line you have to use the tool
Did you find an exact replacement? I replaced this line and some others on my 94 sls and it was quite an adventure, about 4 different size fittings......at least you dont have to do the 11mm one at the abs unit that no one has available
it must be the line thats about 3" long that you are replacing??
yeah it would have been about 3/4 inches long if straightened out. But the replacement that I got is steel. I was thinking of using a piece of pipe that I have to bend it around. The piece that I got is 8 inches long, the smallest piece that the store had available. Yes talk about an adventure, I could not believe the location of that valve. And yes there are about a million different fittings, but the store had a selection of "females" and I had to check the fitting that I brought with me and the fitting on the piece of pipe till they both worked in the same "female"

Re: Replacing Brake Line
You can buy a brake line union. You cut out the bad part of the line, slip part of the union onto the line, flare the line with a flare tool, and add the union. You do not have to replace the entire length of line. It is actually easier than it sounds. I had to do it on the left rear brake line of my '02 SLS. It rusted away where it crosses from the right side of the car just in front of the rear cradle.
thats the problem, if it rusted away you should replace the whole line, it will give you problems later.
If you get the flare tool, i suppose you can do a regular flare, but if you do the bubble flare, the tool is very expensive and parts store dont carrry the line ends.
which part are you talking about, from the valve to the front of car? It goes all the way to the abs module under your airbox in the engine compartment
Im pretty sure the valve at my left rear, was for the right rear brake.......my left rear prop vavle was up by the engine bay.
I replaced both lines from abs unit back to that rear valve location, am im pretty sure your 94 was about like mine and splicing is a temp fix. Only issue is one of the fitting on the abs unit is 11mm and no one carries that line or end.
the proportioner valve for the left rear is lodged up there between the frame and suspension apparatus. I am sure of this. Anyway the pipe leads from the valve to the front(ABS unit) of the car is broken and it is broken right there at the fitting. The line that I am concerned about right now is not rusted this is why I am considering making a joint.
So it is one piece of pipe from ABS unit to p valve?
and what is this flaring tool?
first you need to find an end, unless you can reuse the one you have.
cut the line, put your end on, the flare tool will be in any auto parts store with the brake lines, but it will be a standard flare or double flare (not a bubble flare) You have to flare the line after the end is slid onto it. Then buy the coupler and a new piece of line to make it to the prop block, how long is your call, cut where needed once you get back with whatever length line will make it easier (like dont splice it up in there by the prop block) splice it down by the fuel lines or something thats easily accessable.
For sure when you reuse the bubble flare fitting at the block (and your going to have to use bubble flare here) you will need to put the fitting on the new piece of line, then get the bubble flare tool ( this tool is between $80 and $180) and create the flare.
And as long as you have to use bubble flare there, you might as well use bubble flare at the other purple fittings and the butt connector, since you will already have the tool anyway.
